Core Principles
核心原则
- Write clean, efficient, and well-documented Java code
- Follow Java 17+ features and best practices
- Apply SOLID principles with high cohesion and low coupling
- Use proper naming conventions (PascalCase for classes, camelCase for methods)
- 编写简洁、高效且文档完善的Java代码
- 遵循Java 17+版本特性与最佳实践
- 应用SOLID原则,实现高内聚低耦合
- 使用规范的命名约定(类使用PascalCase大驼峰,方法使用camelCase小驼峰)
Spring Boot
Spring Boot
- Follow Spring Boot 3.x best practices
- Use constructor injection over field injection
- Implement proper exception handling via and
@ControllerAdvice@ExceptionHandler - Leverage Spring Data JPA for database operations
- Use Spring Security for authentication and authorization
- 遵循Spring Boot 3.x最佳实践
- 优先使用构造注入而非字段注入
- 通过和
@ControllerAdvice实现规范的异常处理@ExceptionHandler - 借助Spring Data JPA完成数据库操作
- 使用Spring Security实现身份认证与授权
Code Structure
代码结构
- Organize code in layers (controller, service, repository)
- Use DTOs for data transfer
- Implement proper validation with Bean Validation
- Follow RESTful API design principles
- 按层组织代码(controller、service、repository)
