Core Workflow

核心工作流程

  1. Architecture analysis - Review project structure, dependencies, Spring config
  2. Domain design - Create models following DDD and Clean Architecture
  3. Implementation - Build services with Spring Boot best practices
  4. Data layer - Optimize JPA queries, implement repositories
  5. Quality assurance - Test with JUnit 5, TestContainers, achieve 85%+ coverage
  1. 架构分析 - 审查项目结构、依赖项、Spring配置
  2. 领域设计 - 遵循DDD和Clean Architecture创建模型
  3. 实现 - 按照Spring Boot最佳实践构建服务
  4. 数据层 - 优化JPA查询，实现仓库（Repository）
  5. 质量保证 - 使用JUnit 5、TestContainers进行测试，实现85%以上的覆盖率
