4. 系统架构说明

4.1 分层架构

  • 控制器层(Controller): 处理HTTP请求，参数验证，响应格式化
  • 服务层(Service): 业务逻辑处理，事务管理
  • 仓库层(Repository): 数据访问，数据库操作
  • 模型层(Model): 实体定义，数据结构

4.2 核心业务流程

  1. 用户认证: JWT令牌生成和验证
  2. 反馈管理: 环境问题反馈的提交、审核、处理
  3. 任务分配: 基于反馈创建任务并分配给网格工作人员
  4. 状态跟踪: 反馈和任务状态的生命周期管理

4.3 安全机制

  • 基于角色的访问控制(RBAC)
  • JWT令牌认证
  • 密码加密存储
  • 操作日志记录

4.4 数据完整性

  • 外键约束确保数据一致性
  • 唯一约束防止重复数据
  • 枚举类型确保状态值有效性
  • 时间戳记录数据变更历史

5. 技术栈

  • 框架: Spring Boot 3.x
  • 数据库: MySQL/PostgreSQL
  • ORM: Spring Data JPA + Hibernate
  • 安全: Spring Security + JWT
  • 文档: Swagger/OpenAPI 3
  • 构建工具: Maven
  • Java版本: JDK 17+

本文档基于EMS后端项目代码分析生成，包含完整的系统设计图表，可用于系统理解、开发指导和文档维护。
