📦 核心服务实现

1. API网关服务设计

gateway-service架构：

// GatewayApplication.java
@SpringBootApplication
@EnableDiscoveryClient
public class GatewayApplication {public static void main(String[] args) {SpringApplication.run(GatewayApplication.class, args);}
}// 网关配置
@Configuration
public class GatewayConfig {@Beanpublic RouteLocator customRouteLocator(RouteLocatorBuilder builder) {return builder.routes().route("user-service", r -> r.path("/api/user/**").filters(f -> f.stripPrefix(2).addRequestHeader("X-Gateway", "spring-cloud-gateway").circuitBreaker(config -> config.setName("userServiceCB"))).uri("lb://user-service")).route("product-service", r -> r.path("/api/product/**").filters(f -> f.stripPrefix(2).retry(retryConfig -> retryConfig.setRetries(3))).uri("lb://product-service")).route("order-service", r -> r.path("/api/order/**").filters(f -> f.stripPrefix(2).requestRateLimiter(config -> {config.setRateLimiter(redisRateLimiter());config.setKeyResolver(userKeyResolver());})).uri("lb://order-service")).build();}@Beanpublic RedisRateLimiter redisRateLimiter() {return new RedisRateLimiter(10, 20, 1);}@Beanpublic KeyResolver userKeyResolver() {return exchange -> exchange.getRequest().getHeaders().getFirst("X-User-Id") != null ? Mono.just(exchange.getRequest().getHeaders().getFirst("X-User-Id")) :Mono.just("anonymous");}
}// 全局异常处理
@Component
@Order(-1)
public class GlobalErrorHandler implements ErrorWebExceptionHandler {@Overridepublic Mono<Void> handle(ServerWebExchange exchange, Throwable ex) {ServerHttpResponse response = exchange.getResponse();response.getHeaders().add("Content-Type", "application/json;charset=UTF-8");String errorMsg = switch (ex) {case ConnectTimeoutException ignored -> "服务连接超时";case CircuitBreakerOpenException ignored -> "服务熔断，请稍后重试";case RetryExhaustedException ignored -> "服务重试次数耗尽";default -> "网关内部错误";};String result = """{"code": 500,"message": "%s","timestamp": %d}""".formatted(errorMsg, System.currentTimeMillis());DataBuffer buffer = response.bufferFactory().wrap(result.getBytes());return response.writeWith(Mono.just(buffer));}
}

gateway配置文件：

# application.yml

management:endpoints:web:exposure:include: health,info,gatewayendpoint:health:show-details: always# 日志配置
logging:level:org.springframework.cloud.gateway: DEBUGreactor.netty.http.client: DEBUG

2. 用户服务实现

用户服务核心代码：

// UserService
@Service
@Transactional
@Slf4j
public class UserService {@Autowiredprivate UserRepository userRepository;@Autowiredprivate RedisTemplate<String, Object> redisTemplate;@Autowiredprivate UserEventPublisher eventPublisher;public UserDTO createUser(CreateUserRequest request) {log.info("创建用户: {}", request.getUsername());// 检查用户名是否存在if (userRepository.existsByUsername(request.getUsername())) {throw new BusinessException("用户名已存在");}// 创建用户User user = User.builder().username(request.getUsername()).email(request.getEmail()).password(passwordEncoder.encode(request.getPassword())).phone(request.getPhone()).status(UserStatus.ACTIVE).build();User savedUser = userRepository.save(user);// 发布用户创建事件eventPublisher.publishUserCreatedEvent(savedUser);// 清除相关缓存redisTemplate.delete("user:list:*");log.info("用户创建成功: {}", savedUser.getId());return convertToDTO(savedUser);}@Cacheable(value = "user:detail", key = "#userId", unless = "#result == null")public UserDTO getUserById(Long userId) {User user = userRepository.findById(userId).orElseThrow(() -> new BusinessException("用户不存在"));return convertToDTO(user);}@CacheEvict(value = "user:detail", key = "#userId")public UserDTO updateUser(Long userId, UpdateUserRequest request) {User user = userRepository.findById(userId).orElseThrow(() -> new BusinessException("用户不存在"));// 更新用户信息user.setEmail(request.getEmail());user.setPhone(request.getPhone());User savedUser = userRepository.save(user);// 发布用户更新事件eventPublisher.publishUserUpdatedEvent(savedUser);return convertToDTO(savedUser);}private UserDTO convertToDTO(User user) {return UserDTO.builder().id(user.getId()).username(user.getUsername()).email(user.getEmail()).phone(user.getPhone()).status(user.getStatus()).createTime(user.getCreateTime()).build();}
}// UserController
@RestController
@RequestMapping("/users")
@Validated
@Slf4j
public class UserController {@Autowiredprivate UserService userService;@PostMappingpublic Result<UserDTO> createUser(@Valid @RequestBody CreateUserRequest request) {UserDTO user = userService.createUser(request);return Result.success(user);}@GetMapping("/{userId}")public Result<UserDTO> getUserById(@PathVariable Long userId) {UserDTO user = userService.getUserById(userId);return Result.success(user);}@PutMapping("/{userId}")public Result<UserDTO> updateUser(@PathVariable Long userId, @Valid @RequestBody UpdateUserRequest request) {UserDTO user = userService.updateUser(userId, request);return Result.success(user);}@GetMapping("/{userId}/orders")public Result<List<OrderDTO>> getUserOrders(@PathVariable Long userId) {// 通过Feign调用订单服务List<OrderDTO> orders = orderServiceClient.getOrdersByUserId(userId);return Result.success(orders);}
}// Feign客户端
@FeignClient(name = "order-service",fallbackFactory = OrderServiceFallbackFactory.class,configuration = FeignConfig.class
)
public interface OrderServiceClient {@GetMapping("/orders/user/{userId}")List<OrderDTO> getOrdersByUserId(@PathVariable("userId") Long userId);@PostMapping("/orders/{orderId}/cancel")Result<Void> cancelOrder(@PathVariable("orderId") Long orderId);
}// Feign降级处理
@Component
public class OrderServiceFallbackFactory implements FallbackFactory<OrderServiceClient> {@Overridepublic OrderServiceClient create(Throwable cause) {log.error("订单服务调用失败", cause);return new OrderServiceClient() {@Overridepublic List<OrderDTO> getOrdersByUserId(Long userId) {// 返回缓存数据或空列表return Collections.emptyList();}@Overridepublic Result<Void> cancelOrder(Long orderId) {return Result.error("订单服务暂时不可用，请稍后重试");}};}
}

3. 订单服务实现

订单服务核心业务：

// OrderService
@Service
@Transactional
@Slf4j
public class OrderService {@Autowiredprivate OrderRepository orderRepository;@Autowiredprivate UserServiceClient userServiceClient;@Autowiredprivate ProductServiceClient productServiceClient;@Autowiredprivate InventoryServiceClient inventoryServiceClient;@Autowiredprivate PaymentServiceClient paymentServiceClient;@Autowiredprivate RocketMQTemplate rocketMQTemplate;@GlobalTransactional(rollbackFor = Exception.class)public OrderDTO createOrder(CreateOrderRequest request) {log.info("创建订单开始: {}", request);try {// 1. 验证用户信息UserDTO user = userServiceClient.getUserById(request.getUserId());if (user == null) {throw new BusinessException("用户不存在");}// 2. 验证商品信息并计算价格List<OrderItem> orderItems = new ArrayList<>();BigDecimal totalAmount = BigDecimal.ZERO;for (CreateOrderRequest.OrderItemRequest itemRequest : request.getItems()) {ProductDTO product = productServiceClient.getProductById(itemRequest.getProductId());if (product == null) {throw new BusinessException("商品不存在: " + itemRequest.getProductId());}// 检查库存boolean hasStock = inventoryServiceClient.checkStock(itemRequest.getProductId(), itemRequest.getQuantity());if (!hasStock) {throw new BusinessException("库存不足: " + product.getName());}OrderItem orderItem = OrderItem.builder().productId(itemRequest.getProductId()).productName(product.getName()).price(product.getPrice()).quantity(itemRequest.getQuantity()).amount(product.getPrice().multiply(BigDecimal.valueOf(itemRequest.getQuantity()))).build();orderItems.add(orderItem);totalAmount = totalAmount.add(orderItem.getAmount());}// 3. 创建订单Order order = Order.builder().userId(request.getUserId()).orderNo(generateOrderNo()).totalAmount(totalAmount).status(OrderStatus.PENDING).orderItems(orderItems).build();Order savedOrder = orderRepository.save(order);// 4. 扣减库存for (OrderItem item : orderItems) {inventoryServiceClient.reduceStock(item.getProductId(), item.getQuantity());}// 5. 创建支付订单CreatePaymentRequest paymentRequest = CreatePaymentRequest.builder().orderId(savedOrder.getId()).userId(savedOrder.getUserId()).amount(savedOrder.getTotalAmount()).build();PaymentDTO payment = paymentServiceClient.createPayment(paymentRequest);// 6. 发送订单创建消息OrderCreatedEvent event = OrderCreatedEvent.builder().orderId(savedOrder.getId()).userId(savedOrder.getUserId()).totalAmount(savedOrder.getTotalAmount()).build();rocketMQTemplate.convertAndSend("order-topic:created", event);log.info("订单创建成功: {}", savedOrder.getId());return convertToDTO(savedOrder, payment);} catch (Exception e) {log.error("订单创建失败", e);throw new BusinessException("订单创建失败: " + e.getMessage());}}@Transactional(readOnly = true)public OrderDTO getOrderById(Long orderId) {Order order = orderRepository.findById(orderId).orElseThrow(() -> new BusinessException("订单不存在"));return convertToDTO(order, null);}@GlobalTransactional(rollbackFor = Exception.class)public void cancelOrder(Long orderId) {Order order = orderRepository.findById(orderId).orElseThrow(() -> new BusinessException("订单不存在"));if (!order.canCancel()) {throw new BusinessException("订单状态不允许取消");}// 恢复库存for (OrderItem item : order.getOrderItems()) {inventoryServiceClient.restoreStock(item.getProductId(), item.getQuantity());}// 取消支付paymentServiceClient.cancelPayment(order.getId());// 更新订单状态order.setStatus(OrderStatus.CANCELLED);orderRepository.save(order);// 发送订单取消消息OrderCancelledEvent event = OrderCancelledEvent.builder().orderId(orderId).userId(order.getUserId()).build();rocketMQTemplate.convertAndSend("order-topic:cancelled", event);}private String generateOrderNo() {return "ORD" + System.currentTimeMillis() + String.format("%04d", new Random().nextInt(10000));}private OrderDTO convertToDTO(Order order, PaymentDTO payment) {return OrderDTO.builder().id(order.getId()).orderNo(order.getOrderNo()).userId(order.getUserId()).totalAmount(order.getTotalAmount()).status(order.getStatus()).items(order.getOrderItems().stream().map(this::convertItemToDTO).collect(Collectors.toList())).payment(payment).createTime(order.getCreateTime()).build();}
}// 支付回调处理
@RocketMQMessageListener(topic = "payment-topic",consumerGroup = "order-payment-consumer",selectorExpression = "success || failed"
)
@Component
public class PaymentResultListener implements RocketMQListener<PaymentResultEvent> {@Autowiredprivate OrderService orderService;@Overridepublic void onMessage(PaymentResultEvent event) {log.info("收到支付结果: {}", event);try {if ("success".equals(event.getStatus())) {orderService.handlePaymentSuccess(event.getOrderId(), event.getPaymentId());} else {orderService.handlePaymentFailed(event.getOrderId(), event.getReason());}} catch (Exception e) {log.error("处理支付结果失败", e);// 可以发送到死信队列或者重试}}
}

4. 配置中心与服务发现

Nacos配置管理：

# 公共配置 (common.yml)
spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverhikari:minimum-idle: 5maximum-pool-size: 20idle-timeout: 300000connection-timeout: 20000max-lifetime: 1200000jpa:hibernate:ddl-auto: validateshow-sql: falseproperties:hibernate:dialect: org.hibernate.dialect.MySQL8Dialectredis:host: localhostport: 6379database: 0timeout: 3000mslettuce:pool:max-active: 8max-idle: 8min-idle: 0# RocketMQ配置

logging:level:com.example: INFOorg.springframework.cloud: DEBUGpattern:console: "%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level [%X{traceId}] %logger{36} - %msg%n"

🔧 分布式事务处理

Seata分布式事务配置

AT模式事务处理：

// 分布式事务配置
@Configuration
public class SeataConfig {@Beanpublic GlobalTransactionScanner globalTransactionScanner() {return new GlobalTransactionScanner("microservice-seata", "microservice-group");}
}// 事务管理器
@Component
public class DistributedTransactionManager {@GlobalTransactional(rollbackFor = Exception.class, timeoutMills = 30000)public void executeDistributedTransaction(TransactionContext context) {try {// 执行业务逻辑context.getActions().forEach(action -> {try {action.execute();} catch (Exception e) {log.error("分布式事务执行失败", e);throw new RuntimeException("事务执行失败", e);}});} catch (Exception e) {log.error("分布式事务回滚", e);throw e;}}
}// TCC模式实现示例
@LocalTCC
public interface InventoryTccService {@TwoPhaseBusinessAction(name = "reduceStock",commitMethod = "commit",rollbackMethod = "rollback")boolean reduceStock(BusinessActionContext context, @BusinessActionContextParameter("productId") Long productId,@BusinessActionContextParameter("quantity") Integer quantity);boolean commit(BusinessActionContext context);boolean rollback(BusinessActionContext context);
}@Service
public class InventoryTccServiceImpl implements InventoryTccService {@Autowiredprivate InventoryRepository inventoryRepository;@Overridepublic boolean reduceStock(BusinessActionContext context, Long productId, Integer quantity) {log.info("TCC Try: 冻结库存 productId={}, quantity={}", productId, quantity);// 冻结库存而不是直接扣减Inventory inventory = inventoryRepository.findByProductId(productId);if (inventory.getAvailableStock() < quantity) {throw new BusinessException("库存不足");}inventory.setFrozenStock(inventory.getFrozenStock() + quantity);inventoryRepository.save(inventory);return true;}@Overridepublic boolean commit(BusinessActionContext context) {Long productId = Long.valueOf(context.getActionContext("productId").toString());Integer quantity = Integer.valueOf(context.getActionContext("quantity").toString());log.info("TCC Commit: 确认扣减库存 productId={}, quantity={}", productId, quantity);Inventory inventory = inventoryRepository.findByProductId(productId);inventory.setActualStock(inventory.getActualStock() - quantity);inventory.setFrozenStock(inventory.getFrozenStock() - quantity);inventoryRepository.save(inventory);return true;}@Overridepublic boolean rollback(BusinessActionContext context) {Long productId = Long.valueOf(context.getActionContext("productId").toString());Integer quantity = Integer.valueOf(context.getActionContext("quantity").toString());log.info("TCC Rollback: 释放冻结库存 productId={}, quantity={}", productId, quantity);Inventory inventory = inventoryRepository.findByProductId(productId);inventory.setFrozenStock(inventory.getFrozenStock() - quantity);inventoryRepository.save(inventory);return true;}
}

📊 监控与链路追踪

Spring Cloud Sleuth + Zipkin

链路追踪配置：

# 链路追踪配置
spring:sleuth:sampler:probability: 1.0  # 采样率100%（生产环境建议0.1）zipkin:base-url: http://localhost:9411sender:type: webweb:client:enabled: truefeign:enabled: truerocketmq:enabled: true

自定义链路追踪：

// 链路追踪组件
@Component
public class TraceService {private final Tracer tracer;public TraceService(Tracer tracer) {this.tracer = tracer;}public <T> T traceCall(String operationName, Supplier<T> supplier) {Span span = tracer.nextSpan().name(operationName);try (Tracer.SpanInScope ws = tracer.withSpanInScope(span)) {span.start();return supplier.get();} catch (Exception e) {span.tag("error", e.getMessage());throw e;} finally {span.end();}}public void addTag(String key, String value) {Span currentSpan = tracer.currentSpan();if (currentSpan != null) {currentSpan.tag(key, value);}}
}// 使用示例
@Service
public class OrderTraceService {@Autowiredprivate TraceService traceService;public OrderDTO createOrder(CreateOrderRequest request) {return traceService.traceCall("create-order", () -> {traceService.addTag("user.id", request.getUserId().toString());traceService.addTag("order.items.count", String.valueOf(request.getItems().size()));// 执行业务逻辑return doCreateOrder(request);});}
}

🚀 部署配置

Docker化部署

多服务docker-compose：
