+# 数据同步微服务
+
+## 项目简介
+
+数据同步微服务用于从第三方接口同步人员、项目和报告数据到MySQL数据库。支持定时任务自动同步和手动触发同步。
+
+## 功能特性
+
+1. **数据同步**
+   - 从第三方接口同步人员数据
+   - 从第三方接口同步项目（工程）数据
+   - 从第三方接口同步报告数据
+   - 支持字段大小写兼容
+
+2. **同步方式**
+   - 定时任务：每晚12点自动执行全量同步
+   - 手动触发：通过REST API手动触发同步
+
+3. **同步策略**
+   - 先删除表中所有现有数据
+   - 再全量同步接口返回的数据
+   - 使用接口返回的ID作为主键
+

+
+## API接口
+
+### 1. 同步所有数据
+- **URL**: `/api/v1/sync/all`
+- **方法**: POST
+- **说明**: 同步人员、项目和报告数据
+
+### 2. 同步人员数据
+- **URL**: `/api/v1/sync/employees`
+- **方法**: POST
+- **说明**: 仅同步人员数据
+
+### 3. 同步项目数据
+- **URL**: `/api/v1/sync/projects`
+- **方法**: POST
+- **说明**: 仅同步项目数据
+
+### 4. 同步报告数据
+- **URL**: `/api/v1/sync/reports`
+- **方法**: POST
+- **说明**: 仅同步报告数据
+
+## 定时任务
+
+定时任务配置在 `DataSyncScheduledTask` 类中，使用 cron 表达式：
+- **执行时间**: 每晚12点（0 0 0 * * ?）
+- **执行内容**: 同步所有数据（人员、项目、报告）
+
+## 部署说明
+
+### 1. 数据库初始化
+
+执行 `src/main/resources/db/schema.sql` 创建数据库表。
+
+### 2. 构建项目
+
+```bash
+mvn clean package
+```
+
+### 3. Docker部署
+
+```bash
+docker build -t data-sync-service:1.0.0 .
+docker run -d -p 8080:8080 \
+  -e MYSQL_HOST=your-mysql-host \
+  -e MYSQL_USERNAME=your-username \
+  -e MYSQL_PASSWORD=your-password \
+  data-sync-service:1.0.0
+```
+
+## 注意事项
+
+1. **字段大小写兼容**: 使用 `@JsonProperty` 注解处理接口返回字段的大小写差异
+2. **ID使用**: 使用接口返回的ID作为数据库主键，不自动生成
+3. **同步策略**: 
+   - 人员数据：增量同步（不删除现有数据），新增用户密码为手机号后六位，老用户密码保持不变
+   - 项目和报告数据：全量同步（先删除后插入）
+4. **密码管理**: 
+   - 新增用户：密码自动设置为手机号后六位
+   - 更新用户：密码字段不会被修改，保持原有密码
+5. **事务管理**: 同步操作使用事务，失败时会回滚
+6. **日志记录**: 所有同步操作都会记录详细日志
+
+## 开发规范
+
+本项目遵循《微服务开发规范文档.md》中的开发规范，包括：
+- 代码风格规范
+- 命名规范
+- 异常处理规范
+- 日志规范

+# label_backend 标准目录扁平化 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 把 `com.label.module.*` 与 `com.label.common.aop/common.config` 迁移到规范要求的扁平目录，保证行为不变。
+
+**Architecture:** 先写迁移守卫测试，再按 `基础设施 -> 数据层 -> 服务层 -> 控制层 -> 清理回归` 的顺序做 `git mv` 和导包修正，每阶段都用最小测试集验证。
+
+**Tech Stack:** Java 21、Spring Boot 3.1.5、MyBatis-Plus、Shiro、JUnit 5、AssertJ、Maven

+

+
+Expected: 没有 Java 文件残留；确认后删除空目录。

+## 自检
+
+- 覆盖了 `annotation / aspect / config / event / listener / dto / entity / mapper / service / controller`
+- 没有引入 `service.impl`
+- 没有拆分 `dto/request`、`dto/response`

+@TableName("table_name")
+public class EntityName {
+    @TableId(type = IdType.AUTO)
+    private Long id;
+    
+    private String fieldName;
+    
+    @TableField("is_deleted")
+    private Integer isDeleted;
+    
+    @TableField(exist = false)

+    
+    private final ModuleService moduleService;
+
+    @Operation(summary = "接口描述")
+    @GetMapping("/endpoint")
+    public Result<ResponseType> methodName() {
+        // 业务逻辑
+        return Result.success(data);
+    }
+}
+```
+

+    com.example.{service-name}: DEBUG
+
+# Feign配置
+feign:
+  client:
+    config:
+      default:
+        connectTimeout: 5000
+        readTimeout: 10000
+        loggerLevel: basic
+  compression:
+    request:
+      enabled: true
+    response:
+      enabled: true
+```
+
+### 2. 生产环境配置 (application-pro.yml)

+    com.example.{service-name}: INFO
+
+feign:
+  client:
+    config:
+      default:
+        loggerLevel: basic
+```
+
+## 新微服务MongoDB配置
+
+### 1. 添加MongoDB依赖
+```xml
+<!-- MongoDB依赖 -->
+<dependency>
+    <groupId>org.springframework.boot</groupId>
+    <artifactId>spring-boot-starter-data-mongodb</artifactId>
+</dependency>
+```
+
+### 2. MongoDB配置类
+```java
+@Configuration
+@EnableMongoRepositories(basePackages = "com.example.{service-name}.repository")
+public class MongoConfig {
+    
+    @Bean
+    public MongoTemplate mongoTemplate(MongoDatabaseFactory mongoDatabaseFactory) {
+        return new MongoTemplate(mongoDatabaseFactory);
+    }
+}
+```
+
+### 3. MongoDB实体类规范
+```java
+@Document(collection = "collection_name")
+@Data
+public class MongoEntity {
+    @Id
+    private String id;
+    
+    @Field("field_name")
+    private String fieldName;
+    
+    @CreatedDate
+    private LocalDateTime createdAt;
+    
+    @LastModifiedDate
+    private LocalDateTime updatedAt;
+}
+```
+
+### 4. MongoDB Repository规范
+```java
+@Repository
+public interface MongoEntityRepository extends MongoRepository<MongoEntity, String> {
+    // 自定义查询方法
+    List<MongoEntity> findByFieldName(String fieldName);
+}
+```
+
+## 开发规范
+
+### 1. 包命名规范
+- 基础包名: `com.example.{service-name}`
+- 服务名使用小写字母和连字符，如: `user-service`, `order-service`
+
+### 2. 类命名规范
+- 实体类: 使用名词，如 `User`, `Order`
+- 控制器: 以 `Controller` 结尾，如 `UserController`
+- 服务类: 以 `Service` 结尾，如 `UserService`
+- DTO类: 以 `Request`/`Response` 结尾，如 `UserRequest`, `UserResponse`
+- 常量类: 以 `Constants` 结尾，如 `UserConstants`
+
+### 3. 方法命名规范
+- 查询方法: `get`, `find`, `list`, `query`
+- 创建方法: `create`, `add`, `save`
+- 更新方法: `update`, `modify`
+- 删除方法: `delete`, `remove`
+
+### 4. 异常处理规范
+- 使用统一的异常处理机制
+- 自定义业务异常继承 `RuntimeException`
+- 使用 `@ControllerAdvice` 进行全局异常处理
+
+### 5. 日志规范
+- 使用 `@Slf4j` 注解
+- 日志级别: DEBUG(开发), INFO(生产)
+- 关键操作必须记录日志
+
+## 部署配置
+
+### 1. Dockerfile规范
+```dockerfile
+FROM registry.bjzgzp.com:4433/library/eclipse-temurin:21-jdk-ubi10-minimal
+
+WORKDIR /app
+
+COPY ./target/{service-name}.jar /app/{service-name}.jar
+
+EXPOSE 8080
+
+ENTRYPOINT ["java", "-Djava.net.preferIPv4Stack=true", "-jar", "/app/{service-name}.jar"]
+```
+
+### 2. Maven配置
+```xml
+<build>
+    <finalName>${project.artifactId}</finalName>
+    <plugins>
+        <plugin>
+            <groupId>org.springframework.boot</groupId>
+            <artifactId>spring-boot-maven-plugin</artifactId>
+        </plugin>
+        <plugin>
+            <groupId>org.apache.maven.plugins</groupId>
+            <artifactId>maven-surefire-plugin</artifactId>
+            <configuration>
+                <skipTests>true</skipTests>
+            </configuration>
+        </plugin>
+        <plugin>
+            <groupId>org.apache.maven.plugins</groupId>
+            <artifactId>maven-compiler-plugin</artifactId>
+            <version>3.11.0</version>
+            <configuration>
+                <source>21</source>
+                <target>21</target>
+            </configuration>
+        </plugin>
+    </plugins>
+</build>
+```
+
+## 注意事项
+
+1. **数据库选择**: 新微服务使用MongoDB 6.x，移除MySQL相关依赖
+2. **版本兼容性**: 确保所有依赖版本与当前项目保持一致
+3. **配置管理**: 使用环境变量管理敏感配置信息
+4. **服务发现**: 使用Nacos进行服务注册与发现
+5. **API文档**: 使用SpringDoc OpenAPI 3生成API文档
+6. **缓存策略**: 使用Redis进行缓存和会话管理
+7. **监控日志**: 集成适当的监控和日志记录机制
+
+## 快速开始模板
+
+创建新微服务时，可以参考以下步骤：
+
+1. 复制当前项目的 `pom.xml`，修改 `artifactId` 和 `name`
+2. 移除MySQL相关依赖，添加MongoDB依赖
+3. 复制项目结构，修改包名
+4. 配置MongoDB连接信息
+5. 创建基础的Controller、Service、Repository
+6. 配置Dockerfile和部署脚本
+
+遵循以上规范可以确保新微服务与现有系统保持一致的技术栈和代码风格。
