🏗️ 核心架构设计

微服务模块划分

yudao-cloud采用清晰的服务边界划分，每个模块职责单一：

服务模块	功能描述	技术特点
`yudao-gateway`	API网关服务	Spring Cloud Gateway + 动态路由
`yudao-server`	主业务服务	聚合所有业务模块
`yudao-module-system`	系统管理	RBAC权限+多租户
`yudao-module-infra`	基础设施	监控+配置+任务调度
`yudao-module-member`	会员中心	用户体系+积分管理
`yudao-module-bpm`	工作流程	Flowable引擎
`yudao-module-pay`	支付系统	多支付渠道集成

依赖管理架构

项目采用Maven BOM（Bill of Materials）统一管理依赖版本：

🚀 快速开始：5分钟搭建微服务环境

环境准备

# 1. 克隆项目
git clone https://gitcode.com/gh_mirrors/yu/yudao-cloud

# 2. 安装依赖
cd yudao-cloud
mvn clean install -DskipTests

# 3. 启动Nacos（使用Docker）
docker run --name nacos -e MODE=standalone -p 8848:8848 nacos/nacos-server:2.2.3

# 4. 启动Redis
docker run --name redis -p 6379:6379 redis:6.2-alpine

# 5. 启动MySQL
docker run --name mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 mysql:8.0

数据库初始化

执行SQL脚本初始化数据库：

-- 创建数据库
CREATE DATABASE IF NOT EXISTS `yudao-cloud` DEFAULT CHARACTER SET utf8mb4;

-- 导入基础表结构
SOURCE /path/to/yudao-cloud/sql/mysql/ruoyi-vue-pro.sql;

-- 导入Quartz定时任务表
SOURCE /path/to/yudao-cloud/sql/mysql/quartz.sql;

服务配置

配置Nacos作为配置中心：

# application.yml
spring:
  application:
    name: yudao-server
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yaml
        shared-configs:
          - data-id: common.yaml
            refresh: true
          - data-id: datasource.yaml
            refresh: true
          - data-id: redis.yaml
            refresh: true

🔧 核心组件深度解析

1. Spring Cloud Gateway网关配置

# gateway路由配置
spring:
  cloud:
    gateway:
      routes:
        - id: system-route
          uri: lb://yudao-system-service
          predicates:
            - Path=/system/**
          filters:
            - name: RequestRateLimiter
              args:
                redis-rate-limiter.replenishRate: 10
                redis-rate-limiter.burstCapacity: 20
            - name: StripPrefix=1

2. Nacos服务发现与配置

// 服务注册示例
@SpringBootApplication
@EnableDiscoveryClient
public class SystemServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(SystemServiceApplication.class, args);
    }
}

// 配置动态刷新
@RefreshScope
@RestController
public class ConfigController {
    
    @Value("${app.config.value}")
    private String configValue;
    
    @GetMapping("/config")
    public String getConfig() {
        return configValue;
    }
}

3. Sentinel流量控制

// 资源保护注解
@SentinelResource(value = "userQuery", blockHandler = "handleBlock")
@GetMapping("/users/{id}")
public User getUser(@PathVariable Long id) {
    return userService.getUserById(id);
}

// 降级处理方法
public User handleBlock(Long id, BlockException ex) {
    return User.fallbackUser(id);
}

// 规则配置
@PostConstruct
public void initRules() {
    List<FlowRule> rules = new ArrayList<>();
    FlowRule rule = new FlowRule();
    rule.setResource("userQuery");
    rule.setGrade(RuleConstant.FLOW_GRADE_QPS);
    rule.setCount(100); // 每秒100个请求
    rules.add(rule);
    FlowRuleManager.loadRules(rules);
}

4. Seata分布式事务

// 全局事务注解
@GlobalTransactional
@PostMapping("/order/create")
public Order createOrder(@RequestBody OrderRequest request) {
    // 1. 创建订单
    Order order = orderService.createOrder(request);
    
    // 2. 扣减库存
    inventoryService.deductStock(request.getProductId(), request.getQuantity());
    
    // 3. 扣减余额
    accountService.deductBalance(request.getUserId(), order.getAmount());
    
    return order;
}

    participant Nacos
    participant ServiceA
    participant ServiceB
    participant Sentinel
    participant Database

    Client->>Gateway: 请求/api/service
    Gateway->>Nacos: 获取服务实例
    Nacos-->>Gateway: 返回健康实例列表

    Database-->>ServiceB: 返回结果
    ServiceB-->>ServiceA: 返回数据

熔断降级配置

# Sentinel熔断规则
spring:
  cloud:
    sentinel:
      transport:
        dashboard: localhost:8080
      datasource:
        ds1:
          nacos:
            server-addr: localhost:8848
            dataId: sentinel-rules
            groupId: DEFAULT_GROUP
            rule-type: flow

# Hystrix配置（备用）
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 10000
      circuitBreaker:
        requestVolumeThreshold: 20
        sleepWindowInMilliseconds: 5000

🛡️ 安全与监控

JWT认证体系

// JWT工具类
@Component
public class JwtTokenUtil {
    
    private static final String SECRET_KEY = "yudao-cloud-secret";
    private static final long EXPIRATION = 86400000; // 24小时
    
    public String generateToken(UserDetails userDetails) {
        return Jwts.builder()
                .setSubject(userDetails.getUsername())
                .setIssuedAt(new Date())
                .setExpiration(new Date(System.currentTimeMillis() + EXPIRATION))
                .signWith(SignatureAlgorithm.HS512, SECRET_KEY)
                .compact();
    }
    
    public boolean validateToken(String token, UserDetails userDetails) {
        final String username = extractUsername(token);
        return (username.equals(userDetails.getUsername()) && !isTokenExpired(token));
    }
}

监控体系搭建

# Spring Boot Admin配置
spring:
  boot:
    admin:
      client:
        url: http://localhost:9090
        instance:
          service-host-type: ip
  application:
    name: yudao-monitor

# SkyWalking APM配置
skywalking:
  agent:
    service_name: yudao-cloud
    collector:
      backend_service: localhost:11800
    logging:
      level: INFO

🎯 性能优化策略

数据库优化

-- 索引优化
CREATE INDEX idx_user_tenant ON sys_user(tenant_id);
CREATE INDEX idx_user_dept ON sys_user(dept_id);
CREATE INDEX idx_log_time ON sys_operate_log(operate_time);

-- 分表策略
-- 按时间分表：sys_log_202501, sys_log_202502
-- 按租户分表：sys_user_tenant1, sys_user_tenant2

缓存策略

// 多级缓存设计
@Service
public class UserService {
    
    @Cacheable(value = "users", key = "#id", unless = "#result == null")
    public User getUserById(Long id) {
        return userMapper.selectById(id);
    }
    
    @CacheEvict(value = "users", key = "#user.id")
    public void updateUser(User user) {
        userMapper.updateById(user);
    }
    
    // 本地缓存 + Redis分布式缓存
    @Cacheable(value = "userDetail", key = "#id", 
               condition = "#id != null", 
               unless = "#result == null")
    public UserDetail getUserDetail(Long id) {
        return userDetailMapper.selectById(id);
    }
}

线程池优化

@Configuration
public class ThreadPoolConfig {
    
    @Bean("taskExecutor")
    public ThreadPoolTaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(50);
        executor.setQueueCapacity(200);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("yudao-task-");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
}

🔍 常见问题解决方案

1. 服务雪崩防护

// 服务降级方案
@Service
public class FallbackService {
    
    @SentinelResource(value = "fallbackService", 
                     fallback = "fallbackHandler",
                     fallbackClass = FallbackHandler.class)
    public String businessMethod() {
        // 业务逻辑
        return "success";
    }
}

// 降级处理类
public class FallbackHandler {
    public static String fallbackHandler(Throwable ex) {
        return "服务暂时不可用，请稍后重试";
    }
}

2. 分布式锁实现

// Redisson分布式锁
@Service
public class DistributedLockService {
    
    @Autowired
    private RedissonClient redissonClient;
    
    public void doWithLock(String lockKey, Runnable task) {
        RLock lock = redissonClient.getLock(lockKey);
        try {
            if (lock.tryLock(10, 30, TimeUnit.SECONDS)) {
                task.run();
            }
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        } finally {
            if (lock.isHeldByCurrentThread()) {
                lock.unlock();
            }
        }
    }
}

3. 数据一致性保障

// 最终一致性方案
@Service
public class EventualConsistencyService {
    
    @Transactional
    public void createOrder(Order order) {
        // 1. 本地事务
        orderMapper.insert(order);
        
        // 2. 发送领域事件
        applicationContext.publishEvent(new OrderCreatedEvent(order));
    }
    
    @EventListener
    @Async
    public void handleOrderCreatedEvent(OrderCreatedEvent event) {
        // 3. 异步处理其他业务
        inventoryService.deductStock(event.getOrder());
        accountService.deductBalance(event.getOrder());
    }
}
