Column(unique true, nullable false) private String code; // 商品编码如 SKU-2024-001 Column(nullable false) private String name; Column(name unit_weight_kg) private BigDecimal unitWeightKg; Column(name shelf_life_days) private Integer shelfLifeDays; // 保质期天数用于临期预警 }// src/main/java/com/example/warehouse/entity/Warehouse.java Entity Table(name t_warehouse) Data public class Warehouse { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id; Column(unique true, nullable false) private String code; // 仓库编码如 WH-BJ-01 private String name; private String address; private Boolean isActive true; }// src/main/java/com/example/warehouse/entity/Location.java Entity Table(name t_location) Data public class Location { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id;

ManyToOne(fetch FetchType.LAZY) JoinColumn(name sku_id, nullable false) private Sku sku; ManyToOne(fetch FetchType.LAZY) JoinColumn(name warehouse_id, nullable false) private Warehouse warehouse; ManyToOne(fetch FetchType.LAZY) JoinColumn(name location_id, nullable false) private Location location; Column(name quantity, nullable false) private Integer quantity 0; Column(name batch_no) private String batchNo; // 批次号用于先进先出 FIFO Column(name production_date) private LocalDate productionDate; Column(name expire_date) private LocalDate expireDate; Column(name updated_at) LastModifiedDate private LocalDateTime updatedAt; }注意LastModifiedDate来自EnableJpaAuditing需在主启动类添加该注解并确保Stock类实现PersistableLong或使用CreatedDate/LastModifiedDate配合EntityListeners(AuditingEntityListener.class)。此处采用后者在Stock类顶部添加EntityListeners(AuditingEntityListener.class)即可。2.3 实现库存增删改查 REST API带事务与校验的 Controller创建StockController暴露/api/stocks接口支持按 SKU 查询库存、新增入库记录、扣减出库数量// src/main/java/com/example/warehouse/controller/StockController.java RestController RequestMapping(/api/stocks) RequiredArgsConstructor public class StockController { private final StockService stockService; /** * 查询某 SKU 在指定仓库的实时库存 * GET /api/stocks?skuCodeSKU-2024-001warehouseCodeWH-BJ-01 */ GetMapping public ResponseEntityListStock listBySkuAndWarehouse( RequestParam String skuCode, RequestParam String warehouseCode) { return ResponseEntity.ok(stockService.findBySkuCodeAndWarehouseCode(skuCode, warehouseCode)); } /** * 入库操作增加库存数量支持批量 * POST /api/stocks/inbound * Body: [{skuCode:SKU-2024-001,warehouseCode:WH-BJ-01,locationCode:A-01-01-01,quantity:100,batchNo:BATCH-20240501}] */ PostMapping(/inbound) public ResponseEntityString inbound(Valid RequestBody ListInboundRequest requests) { stockService.inbound(requests); return ResponseEntity.ok(入库成功); } /** * 出库操作扣减库存需校验可用库存是否充足 * POST /api/stocks/outbound * Body: {skuCode:SKU-2024-001,warehouseCode:WH-BJ-01,quantity:50} */ PostMapping(/outbound) public ResponseEntityString outbound(Valid RequestBody OutboundRequest request) { stockService.outbound(request); return ResponseEntity.ok(出库成功); } }配套请求 DTO带校验注解// src/main/java/com/example/warehouse/dto/InboundRequest.java Data public class InboundRequest { NotBlank(message SKU 编码不能为空) private String skuCode; NotBlank(message 仓库编码不能为空) private String warehouseCode; NotBlank(message 货位编码不能为空) private String locationCode; Min(value 1, message 入库数量必须大于 0) private Integer quantity; private String batchNo; private LocalDate productionDate; private LocalDate expireDate; }// src/main/java/com/example/warehouse/dto/OutboundRequest.java Data public class OutboundRequest { NotBlank(message SKU 编码不能为空) private String skuCode; NotBlank(message 仓库编码不能为空) private String warehouseCode; Min(value 1, message 出库数量必须大于 0) private Integer quantity; }Service 层实现关键逻辑事务控制 库存校验// src/main/java/com/example/warehouse/service/StockService.java Service Transactional RequiredArgsConstructor public class StockService { private final StockRepository stockRepository; private final SkuRepository skuRepository; private final WarehouseRepository warehouseRepository; private final LocationRepository locationRepository; public ListStock findBySkuCodeAndWarehouseCode(String skuCode, String warehouseCode) { return stockRepository.findBySku_CodeAndWarehouse_Code(skuCode, warehouseCode); } public void inbound(ListInboundRequest requests) { for (InboundRequest req : requests) { Sku sku skuRepository.findByCode(req.getSkuCode()) .orElseThrow(() - new IllegalArgumentException(SKU 不存在: req.getSkuCode())); Warehouse warehouse warehouseRepository.findByCode(req.getWarehouseCode()) .orElseThrow(() - new IllegalArgumentException(仓库不存在: req.getWarehouseCode())); Location location locationRepository.findByCode(req.getLocationCode()) .orElseThrow(() - new IllegalArgumentException(货位不存在: req.getLocationCode())); Stock existing stockRepository.findBySku_IdAndWarehouse_IdAndLocation_Id( sku.getId(), warehouse.getId(), location.getId()).orElse(null); if (existing null) { // 新建库存记录 Stock stock new Stock(); stock.setSku(sku); stock.setWarehouse(warehouse); stock.setLocation(location); stock.setQuantity(req.getQuantity()); stock.setBatchNo(req.getBatchNo()); stock.setProductionDate(req.getProductionDate()); stock.setExpireDate(req.getExpireDate()); stockRepository.save(stock); } else { // 累加数量 existing.setQuantity(existing.getQuantity() req.getQuantity()); stockRepository.save(existing); } } } public void outbound(OutboundRequest request) { Sku sku skuRepository.findByCode(request.getSkuCode()) .orElseThrow(() - new IllegalArgumentException(SKU 不存在: request.getSkuCode())); Warehouse warehouse warehouseRepository.findByCode(request.getWarehouseCode()) .orElseThrow(() - new IllegalArgumentException(仓库不存在: request.getWarehouseCode())); // 查找该 SKU仓库 下所有库存记录按 expireDate 升序实现 FIFO ListStock stocks stockRepository.findBySku_IdAndWarehouse_IdOrderByExpireDateAsc( sku.getId(), warehouse.getId()); int remaining request.getQuantity(); for (Stock stock : stocks) { if (remaining 0) break; if (stock.getQuantity() remaining) { stock.setQuantity(stock.getQuantity() - remaining); stockRepository.save(stock); remaining 0; } else { remaining - stock.getQuantity(); stock.setQuantity(0); stockRepository.save(stock); } } if (remaining 0) { throw new IllegalStateException(库存不足缺货 remaining 件); } } }逻辑说明outbound()方法实现了FIFO先进先出出库策略通过Query在StockRepository中定义排序查询见下文确保优先消耗最早生产的批次。Transactional保证整个出库过程原子性——若某条记录扣减失败全部回滚。Valid触发InboundRequest和OutboundRequest的NotBlank/Min校验失败时自动返回400 Bad Request及错误字段。Repository 接口需补充自定义查询方法在StockRepository.java中// src/main/java/com/example/warehouse/repository/StockRepository.java public interface StockRepository extends JpaRepositoryStock, Long { ListStock findBySku_CodeAndWarehouse_Code(String skuCode, String warehouseCode); Stock findBySku_IdAndWarehouse_IdAndLocation_Id(Long skuId, Long warehouseId, Long locationId); ListStock findBySku_IdAndWarehouse_IdOrderByExpireDateAsc(Long skuId, Long warehouseId); }3. 引入 Redis 缓存与 RabbitMQ 事件驱动让系统真正“智能”3.1 用 Redis 缓存热点库存数据降低数据库压力库存查询是高频操作扫码枪每秒多次请求直接查 DB 易成为瓶颈。SpringBoot 整合 Redis 极简只需添加 Starter 并配置连接。在pom.xml中加入dependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-data-redis/artifactId /dependency在application.yml中配置 Redis使用本地 Docker 容器spring: redis: host: localhost port: 6379 database: 0 timeout: 2000 lettuce: pool: max-active: 8 max-idle: 8 min-idle: 0 max-wait: 10000启用缓存功能在主启动类添加EnableCachingSpringBootApplication EnableJpaAuditing EnableCaching // ← 关键注解 public class WarehouseApplication { public static void main(String[] args) { SpringApplication.run(WarehouseApplication.class, args); } }在StockService的查询方法上添加CacheableCacheable(value stockBySkuAndWarehouse, key #skuCode _ #warehouseCode) public ListStock findBySkuCodeAndWarehouseCode(String skuCode, String warehouseCode) { return stockRepository.findBySku_CodeAndWarehouse_Code(skuCode, warehouseCode); }参数说明value stockBySkuAndWarehouse是缓存名称对应 Redis 中的 Hash 结构key #skuCode _ #warehouseCode指定缓存键生成规则确保不同参数组合存入不同 key当方法被调用时Spring 先查 Redis命中则返回未命中才执行方法体并存入缓存。但缓存带来新问题数据一致性。入库/出库后必须同步失效对应缓存。使用CacheEvictCacheEvict(value stockBySkuAndWarehouse, key #req.skuCode _ #req.warehouseCode) public void inbound(ListInboundRequest requests) { ... } CacheEvict(value stockBySkuAndWarehouse, key #request.skuCode _ #request.warehouseCode) public void outbound(OutboundRequest request) { ... }注意CacheEvict的key必须与Cacheable完全一致否则无法精准清除。若inbound方法接收的是ListInboundRequest需确保#req.skuCode能正确解析——实际中建议拆分为单条处理或使用 SpEL 表达式遍历此处为简化展示。3.2 用 RabbitMQ 解耦库存变动通知触发预警与同步当库存低于安全阈值如 10 件系统应自动发送短信或邮件。若在outbound()方法内直接调用短信 SDK会导致事务阻塞、耦合度高、失败影响主流程。最佳实践是发布事件由独立消费者处理。添加 AMQP Starterdependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-amqp/artifactId /dependency配置 RabbitMQapplication.ymlspring: rabbitmq: host: localhost port: 5672 username: guest password: guest virtual-host: / listener: simple: prefetch: 1 acknowledge-mode: manual定义库存变动事件消息体// src/main/java/com/example/warehouse/event/StockChangeEvent.java Data public class StockChangeEvent { private String skuCode; private String warehouseCode; private Integer delta; // 变动量正为入库负为出库 private Integer currentQuantity; private LocalDateTime occurredAt; }在StockService的inbound/outbound方法末尾发布事件使用RabbitTemplateService Transactional RequiredArgsConstructor public class StockService { private final RabbitTemplate rabbitTemplate; public void inbound(ListInboundRequest requests) { // ... 原有入库逻辑 requests.forEach(req - { StockChangeEvent event new StockChangeEvent(); event.setSkuCode(req.getSkuCode()); event.setWarehouseCode(req.getWarehouseCode()); event.setDelta(req.getQuantity()); event.setCurrentQuantity(/* 查询最新总量 */); event.setOccurredAt(LocalDateTime.now()); rabbitTemplate.convertAndSend(stock.change.topic, stock.change, event); }); } }创建消费者监听器处理低库存预警// src/main/java/com/example/warehouse/listener/StockAlertListener.java Component RequiredArgsConstructor public class StockAlertListener { private final StockRepository stockRepository; private final SmsService smsService; // 假设已实现 RabbitListener(queues stock.alert.queue) public void handleStockAlert(StockChangeEvent event, Channel channel, Message message) throws IOException { // 查询该 SKU仓库 当前总库存 ListStock stocks stockRepository.findBySku_CodeAndWarehouse_Code( event.getSkuCode(), event.getWarehouseCode()); int total stocks.stream().mapToInt(Stock::getQuantity).sum(); if (total 10) { String content String.format(【智能仓储预警】SKU %s 在 %s 仓库库存仅剩 %d 件请及时补货, event.getSkuCode(), event.getWarehouseCode(), total); smsService.send(13800138000, content); // 实际应查管理员手机号 } channel.basicAck(message.getMessageProperties().getDeliveryTag(), false); } }说明RabbitListener监听stock.alert.queue该队列需通过Bean方式绑定到stock.change.topicExchange 并设置 Routing Key 为stock.change。此处省略声明式绑定代码实际项目中应在RabbitMQConfig.java中定义Queue、TopicExchange和Binding。4. 实现货位智能推荐基于规则引擎的上架策略4.1 定义货位分配规则温度分区 体积匹配 FIFO 原则“智能”在仓储中首先体现为货位推荐新入库商品应放在哪里不能随意堆放。需综合考虑温度要求药品/生鲜需冷藏区普通商品放常温区体积/重量重型货物放底层轻小件放高层批次管理同 SKU 不同批次需隔离存放避免混批动态负载优先选择当前占用率 70% 的货位。我们不引入 Drools 等重型规则引擎而是用 SpringBoot 的Service 策略模式实现轻量级推荐// src/main/java/com/example/warehouse/strategy/LocationRecommendationStrategy.java public interface LocationRecommendationStrategy { OptionalLocation recommend(Sku sku, Warehouse warehouse); } Component RequiredArgsConstructor public class TemperatureAndVolumeStrategy implements LocationRecommendationStrategy { private final LocationRepository locationRepository; Override public OptionalLocation recommend(Sku sku, Warehouse warehouse) { // Step 1: 过滤同仓库、同温度区的货位 String zone getZoneBySku(sku); ListLocation candidates locationRepository.findByWarehouse_IdAndZone( warehouse.getId(), zone); // Step 2: 过滤未满载货位capacity 0 且 isOccupied false candidates candidates.stream() .filter(loc - !loc.getIsOccupied() loc.getCapacity() ! null) .collect(Collectors.toList()); // Step 3: 按容量升序排序优先选小容量货位放小件留大容量给大件 candidates.sort(Comparator.comparing(Location::getCapacity)); // Step 4: 返回第一个可用货位 return candidates.isEmpty() ? Optional.empty() : Optional.of(candidates.get(0)); } private String getZoneBySku(Sku sku) { if (sku.getShelfLifeDays() ! null sku.getShelfLifeDays() 30) { return 冷藏区; } else if (sku.getUnitWeightKg() ! null sku.getUnitWeightKg().compareTo(BigDecimal.valueOf(20)) 0) { return 重型区; } else { return 常温区; } } }4.2 在入库流程中集成推荐策略修改StockService.inbound()在新建Stock前调用推荐public void inbound(ListInboundRequest requests) { for (InboundRequest req : requests) { // ... 获取 sku/warehouse/location 对象 // 若未指定 locationCode则自动推荐 if (req.getLocationCode() null || req.getLocationCode().trim().isEmpty()) { Location recommended locationRecommendationStrategy .recommend(sku, warehouse) .orElseThrow(() - new IllegalStateException(无可用货位)); req.setLocationCode(recommended.getCode()); } // 后续逻辑不变... } }优势策略可插拔。未来若需支持“ABC 分类法”A 类高周转品放黄金货位只需新增AbcClassificationStrategy实现同一接口并通过Primary或Qualifier切换无需修改业务主干。5. 生产环境就绪配置分离、健康检查与 JVM 调优5.1 多环境配置分离dev/test/prod 使用不同数据库与中间件SpringBoot 默认通过spring.profiles.active切换配置。在src/main/resources下创建application.yml公共配置application-dev.yml开发环境H2 内存库 本地 Redisapplication-prod.yml生产环境MySQL 远程 Redis RabbitMQapplication.yml示例spring: profiles: active: activatedProperties application: name: warehouse-service jackson: date-format: yyyy-MM-dd HH:mm:ss time-zone: GMT8 datasource: driver-class-name: com.mysql.cj.jdbc.Driver hikari: maximum-pool-size: 20 minimum-idle: 5 connection-timeout: 30000 idle-timeout: 600000 max-lifetime: 1800000application-prod.yml关键片段spring: profiles: prod datasource: url: jdbc:mysql://prod-mysql:3306/warehouse?useSSLfalseserverTimezoneAsia/ShanghaiallowPublicKeyRetrievaltrue username: warehouse_user password: ${WAREHOUSE_DB_PASSWORD:changeme} # 从环境变量读取 redis: host: prod-redis port: 6379 rabbitmq: host: prod-rabbit port: 5672 virtual-host: warehouse_vhost management: endpoints: web: exposure: include: health,info,metrics,prometheus,loggers endpoint: health: show-details: when_authorized说明activatedProperties在 Maven 构建时由pom.xml的resources配置替换为实际 profile如prod密码等敏感信息通过docker run -e WAREHOUSE_DB_PASSWORDxxx注入避免硬编码。5.2 启用 Actuator 健康检查与 Prometheus 监控添加 Actuator Starterdependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-actuator/artifactId /dependency访问http://localhost:8080/actuator/health可得 JSON 响应{ status: UP, components: { db: { status: UP, details: { database: MySQL, validationQuery: isValid() } }, redis: { status: UP }, rabbit: { status: UP } } }若需对接 Prometheus添加 Micrometer 依赖并暴露/actuator/prometheus端点已在application-prod.yml中配置expose: prometheus。5.3 JVM 启动参数调优适用于 4C8G 服务器在生产启动脚本中添加java \ -Xms2g -Xmx2g \ -XX:UseG1GC \ -XX:MaxGCPauseMillis200 \ -XX:PrintGCDetails \ -XX:PrintGCDateStamps \ -Xloggc:/var/log/warehouse/gc.log \ -jar warehouse.jar \ --spring.profiles.activeprod参数说明-Xms2g -Xmx2g堆内存固定为 2GB避免动态扩容导致 GC 波动-XX:UseG1GC使用 G1 垃圾收集器适合大堆且需可控停顿时间-XX:MaxGCPauseMillis200设定 GC 最大暂停目标为 200ms-Xloggc输出 GC 日志便于分析内存泄漏提示若系统频繁 Full GC需用jstat -gc pid查看 Eden/Survivor/Old 区使用率并结合jmap -histo pid分析对象分布。常见瓶颈是 Redis 缓存未设置 TTL 导致Stock对象长期驻留堆中。最后验证启动服务后执行一次入库请求观察http://localhost:8080/actuator/metrics/jvm.memory.used是否平稳增长调用/api/stocks?skuCode...查看响应时间是否 100msRedis 缓存生效检查 RabbitMQ Management UI 中stock.change.topic的消息流入量是否与入库次数一致——三者齐备即表明智能仓储主干已稳定运行。本文还有配套的精品资源点击获取 SpringBoot构建智能仓储系统：Redis缓存与RabbitMQ事件驱动实战

int remaining request.getQuantity(); for (Stock stock : stocks) { if (remaining 0) break; if (stock.getQuantity() remaining) { stock.setQuantity(stock.getQuantity() - remaining); stockRepository.save(stock); remaining 0; } else { remaining - stock.getQuantity(); stock.setQuantity(0); stockRepository.save(stock); } } if (remaining 0) { throw new IllegalStateException(库存不足缺货 remaining 件); } } }逻辑说明outbound()方法实现了FIFO先进先出出库策略通过Query在StockRepository中定义排序查询见下文确保优先消耗最早生产的批次。Transactional保证整个出库过程原子性——若某条记录扣减失败全部回滚。Valid触发InboundRequest和OutboundRequest的NotBlank/Min校验失败时自动返回400 Bad Request及错误字段。Repository 接口需补充自定义查询方法在StockRepository.java中// src/main/java/com/example/warehouse/repository/StockRepository.java public interface StockRepository extends JpaRepositoryStock, Long { ListStock findBySku_CodeAndWarehouse_Code(String skuCode, String warehouseCode); Stock findBySku_IdAndWarehouse_IdAndLocation_Id(Long skuId, Long warehouseId, Long locationId); ListStock findBySku_IdAndWarehouse_IdOrderByExpireDateAsc(Long skuId, Long warehouseId); }3. 引入 Redis 缓存与 RabbitMQ 事件驱动让系统真正“智能”3.1 用 Redis 缓存热点库存数据降低数据库压力库存查询是高频操作扫码枪每秒多次请求直接查 DB 易成为瓶颈。SpringBoot 整合 Redis 极简只需添加 Starter 并配置连接。在pom.xml中加入dependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-data-redis/artifactId /dependency在application.yml中配置 Redis使用本地 Docker 容器spring: redis: host: localhost port: 6379 database: 0 timeout: 2000 lettuce: pool: max-active: 8 max-idle: 8 min-idle: 0 max-wait: 10000启用缓存功能在主启动类添加EnableCachingSpringBootApplication EnableJpaAuditing EnableCaching // ← 关键注解 public class WarehouseApplication { public static void main(String[] args) { SpringApplication.run(WarehouseApplication.class, args); } }在StockService的查询方法上添加CacheableCacheable(value stockBySkuAndWarehouse, key #skuCode _ #warehouseCode) public ListStock findBySkuCodeAndWarehouseCode(String skuCode, String warehouseCode) { return stockRepository.findBySku_CodeAndWarehouse_Code(skuCode, warehouseCode); }参数说明value stockBySkuAndWarehouse是缓存名称对应 Redis 中的 Hash 结构key #skuCode _ #warehouseCode指定缓存键生成规则确保不同参数组合存入不同 key当方法被调用时Spring 先查 Redis命中则返回未命中才执行方法体并存入缓存。但缓存带来新问题数据一致性。入库/出库后必须同步失效对应缓存。使用CacheEvictCacheEvict(value stockBySkuAndWarehouse, key #req.skuCode _ #req.warehouseCode) public void inbound(ListInboundRequest requests) { ... } CacheEvict(value stockBySkuAndWarehouse, key #request.skuCode _ #request.warehouseCode) public void outbound(OutboundRequest request) { ... }注意CacheEvict的key必须与Cacheable完全一致否则无法精准清除。若inbound方法接收的是ListInboundRequest需确保#req.skuCode能正确解析——实际中建议拆分为单条处理或使用 SpEL 表达式遍历此处为简化展示。3.2 用 RabbitMQ 解耦库存变动通知触发预警与同步当库存低于安全阈值如 10 件系统应自动发送短信或邮件。若在outbound()方法内直接调用短信 SDK会导致事务阻塞、耦合度高、失败影响主流程。最佳实践是发布事件由独立消费者处理。添加 AMQP Starterdependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-amqp/artifactId /dependency配置 RabbitMQapplication.ymlspring: rabbitmq: host: localhost port: 5672 username: guest password: guest virtual-host: / listener: simple: prefetch: 1 acknowledge-mode: manual定义库存变动事件消息体// src/main/java/com/example/warehouse/event/StockChangeEvent.java Data public class StockChangeEvent { private String skuCode; private String warehouseCode; private Integer delta; // 变动量正为入库负为出库 private Integer currentQuantity; private LocalDateTime occurredAt; }在StockService的inbound/outbound方法末尾发布事件使用RabbitTemplateService Transactional RequiredArgsConstructor public class StockService { private final RabbitTemplate rabbitTemplate; public void inbound(ListInboundRequest requests) { // ... 原有入库逻辑 requests.forEach(req - { StockChangeEvent event new StockChangeEvent(); event.setSkuCode(req.getSkuCode()); event.setWarehouseCode(req.getWarehouseCode()); event.setDelta(req.getQuantity()); event.setCurrentQuantity(/* 查询最新总量 */); event.setOccurredAt(LocalDateTime.now()); rabbitTemplate.convertAndSend(stock.change.topic, stock.change, event); }); } }创建消费者监听器处理低库存预警// src/main/java/com/example/warehouse/listener/StockAlertListener.java Component RequiredArgsConstructor public class StockAlertListener { private final StockRepository stockRepository; private final SmsService smsService; // 假设已实现 RabbitListener(queues stock.alert.queue) public void handleStockAlert(StockChangeEvent event, Channel channel, Message message) throws IOException { // 查询该 SKU仓库 当前总库存 ListStock stocks stockRepository.findBySku_CodeAndWarehouse_Code( event.getSkuCode(), event.getWarehouseCode()); int total stocks.stream().mapToInt(Stock::getQuantity).sum(); if (total 10) { String content String.format(【智能仓储预警】SKU %s 在 %s 仓库库存仅剩 %d 件请及时补货, event.getSkuCode(), event.getWarehouseCode(), total); smsService.send(13800138000, content); // 实际应查管理员手机号 } channel.basicAck(message.getMessageProperties().getDeliveryTag(), false); } }说明RabbitListener监听stock.alert.queue该队列需通过Bean方式绑定到stock.change.topicExchange 并设置 Routing Key 为stock.change。此处省略声明式绑定代码实际项目中应在RabbitMQConfig.java中定义Queue、TopicExchange和Binding。4. 实现货位智能推荐基于规则引擎的上架策略4.1 定义货位分配规则温度分区 体积匹配 FIFO 原则“智能”在仓储中首先体现为货位推荐新入库商品应放在哪里不能随意堆放。需综合考虑温度要求药品/生鲜需冷藏区普通商品放常温区体积/重量重型货物放底层轻小件放高层批次管理同 SKU 不同批次需隔离存放避免混批动态负载优先选择当前占用率 70% 的货位。我们不引入 Drools 等重型规则引擎而是用 SpringBoot 的Service 策略模式实现轻量级推荐// src/main/java/com/example/warehouse/strategy/LocationRecommendationStrategy.java public interface LocationRecommendationStrategy { OptionalLocation recommend(Sku sku, Warehouse warehouse); } Component RequiredArgsConstructor public class TemperatureAndVolumeStrategy implements LocationRecommendationStrategy { private final LocationRepository locationRepository; Override public OptionalLocation recommend(Sku sku, Warehouse warehouse) { // Step 1: 过滤同仓库、同温度区的货位 String zone getZoneBySku(sku); ListLocation candidates locationRepository.findByWarehouse_IdAndZone( warehouse.getId(), zone); // Step 2: 过滤未满载货位capacity 0 且 isOccupied false candidates candidates.stream() .filter(loc - !loc.getIsOccupied() loc.getCapacity() ! null) .collect(Collectors.toList()); // Step 3: 按容量升序排序优先选小容量货位放小件留大容量给大件 candidates.sort(Comparator.comparing(Location::getCapacity)); // Step 4: 返回第一个可用货位 return candidates.isEmpty() ? Optional.empty() : Optional.of(candidates.get(0)); } private String getZoneBySku(Sku sku) { if (sku.getShelfLifeDays() ! null sku.getShelfLifeDays() 30) { return 冷藏区; } else if (sku.getUnitWeightKg() ! null sku.getUnitWeightKg().compareTo(BigDecimal.valueOf(20)) 0) { return 重型区; } else { return 常温区; } } }4.2 在入库流程中集成推荐策略修改StockService.inbound()在新建Stock前调用推荐public void inbound(ListInboundRequest requests) { for (InboundRequest req : requests) { // ... 获取 sku/warehouse/location 对象 // 若未指定 locationCode则自动推荐 if (req.getLocationCode() null || req.getLocationCode().trim().isEmpty()) { Location recommended locationRecommendationStrategy .recommend(sku, warehouse) .orElseThrow(() - new IllegalStateException(无可用货位)); req.setLocationCode(recommended.getCode()); } // 后续逻辑不变... } }优势策略可插拔。未来若需支持“ABC 分类法”A 类高周转品放黄金货位只需新增AbcClassificationStrategy实现同一接口并通过Primary或Qualifier切换无需修改业务主干。5. 生产环境就绪配置分离、健康检查与 JVM 调优5.1 多环境配置分离dev/test/prod 使用不同数据库与中间件SpringBoot 默认通过spring.profiles.active切换配置。在src/main/resources下创建application.yml公共配置application-dev.yml开发环境H2 内存库 本地 Redisapplication-prod.yml生产环境MySQL 远程 Redis RabbitMQapplication.yml示例spring: profiles: active: activatedProperties application: name: warehouse-service jackson: date-format: yyyy-MM-dd HH:mm:ss time-zone: GMT8 datasource: driver-class-name: com.mysql.cj.jdbc.Driver hikari: maximum-pool-size: 20 minimum-idle: 5 connection-timeout: 30000 idle-timeout: 600000 max-lifetime: 1800000application-prod.yml关键片段spring: profiles: prod datasource: url: jdbc:mysql://prod-mysql:3306/warehouse?useSSLfalseserverTimezoneAsia/ShanghaiallowPublicKeyRetrievaltrue username: warehouse_user password: ${WAREHOUSE_DB_PASSWORD:changeme} # 从环境变量读取 redis: host: prod-redis port: 6379 rabbitmq: host: prod-rabbit port: 5672 virtual-host: warehouse_vhost management: endpoints: web: exposure: include: health,info,metrics,prometheus,loggers endpoint: health: show-details: when_authorized说明activatedProperties在 Maven 构建时由pom.xml的resources配置替换为实际 profile如prod密码等敏感信息通过docker run -e WAREHOUSE_DB_PASSWORDxxx注入避免硬编码。5.2 启用 Actuator 健康检查与 Prometheus 监控添加 Actuator Starterdependency groupIdorg.springframework.boot/groupId artifactIdspring-boot-starter-actuator/artifactId /dependency访问http://localhost:8080/actuator/health可得 JSON 响应{ status: UP, components: { db: { status: UP, details: { database: MySQL, validationQuery: isValid() } }, redis: { status: UP }, rabbit: { status: UP } } }若需对接 Prometheus添加 Micrometer 依赖并暴露/actuator/prometheus端点已在application-prod.yml中配置expose: prometheus。5.3 JVM 启动参数调优适用于 4C8G 服务器在生产启动脚本中添加java \ -Xms2g -Xmx2g \ -XX:UseG1GC \ -XX:MaxGCPauseMillis200 \ -XX:PrintGCDetails \ -XX:PrintGCDateStamps \ -Xloggc:/var/log/warehouse/gc.log \ -jar warehouse.jar \ --spring.profiles.activeprod参数说明-Xms2g -Xmx2g堆内存固定为 2GB避免动态扩容导致 GC 波动-XX:UseG1GC使用 G1 垃圾收集器适合大堆且需可控停顿时间-XX:MaxGCPauseMillis200设定 GC 最大暂停目标为 200ms-Xloggc输出 GC 日志便于分析内存泄漏提示若系统频繁 Full GC需用jstat -gc pid查看 Eden/Survivor/Old 区使用率并结合jmap -histo pid分析对象分布。常见瓶颈是 Redis 缓存未设置 TTL 导致Stock对象长期驻留堆中。最后验证启动服务后执行一次入库请求观察http://localhost:8080/actuator/metrics/jvm.memory.used是否平稳增长调用/api/stocks?skuCode...查看响应时间是否 100msRedis 缓存生效检查 RabbitMQ Management UI 中stock.change.topic的消息流入量是否与入库次数一致——三者齐备即表明智能仓储主干已稳定运行。本文还有配套的精品资源点击获取
