服务依赖关系
# 服务间调用关系
gateway-service:
- routes to all services
order-service:
- calls: user-service, product-service, inventory-service, payment-service
- sends: notification-service (async)
payment-service:
- calls: user-service
- sends: order-service (callback)
inventory-service:
- calls: product-service
notification-service:
- receives: order-service, payment-service
📦 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 {
@Bean
public 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();
}
@Bean
public RedisRateLimiter redisRateLimiter() {
return new RedisRateLimiter(10, 20, 1);
}
@Bean
public 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 {
@Override
public 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));
}
}

2. 用户服务实现
用户服务核心代码：
// UserService
@Service
@Transactional
@Slf4j
public class UserService {
@Autowired
private UserRepository userRepository;
@Autowired
private RedisTemplate<String, Object> redisTemplate;
@Autowired
private 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 {
@Autowired
private UserService userService;
@PostMapping
public 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> {
@Override
public OrderServiceClient create(Throwable cause) {
log.error("订单服务调用失败", cause);
return new OrderServiceClient() {
@Override
public List<OrderDTO> getOrdersByUserId(Long userId) {
// 返回缓存数据或空列表
return Collections.emptyList();
}
@Override
public 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 {
@Autowired
private OrderRepository orderRepository;
@Autowired
private UserServiceClient userServiceClient;
@Autowired
private ProductServiceClient productServiceClient;
@Autowired
private InventoryServiceClient inventoryServiceClient;
@Autowired
private PaymentServiceClient paymentServiceClient;
@Autowired
private 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> {
@Autowired
private OrderService orderService;
@Override
public 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

🔧 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 {
@Bean
public 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 {
@Autowired
private InventoryRepository inventoryRepository;
@Override
public 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;
}
@Override
public 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;
}
@Override
public 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:9411
sender:
type: web
web:
client:
enabled: true
feign:
enabled: true
rocketmq:
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 {
@Autowired
private 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);
});
}
}
