Code Style and Structure
代码风格与结构
- Write clean, efficient, and well-documented Java code with accurate Spring Boot examples
- Follow camelCase for methods and variables, PascalCase for classes
- Structure applications with clear separation: controllers, services, repositories, models, and configurations
- 编写简洁、高效且文档完善的Java代码,并提供准确的Spring Boot示例
- 方法和变量遵循驼峰式命名(camelCase),类遵循帕斯卡命名(PascalCase)
- 应用结构清晰分离:控制器、服务、仓库、模型及配置类
Spring Boot Specifics
Spring Boot 专属规范
- Utilize Spring Boot starters for quick project setup
- Implement proper use of annotations (@SpringBootApplication, @RestController, @Service)
- Leverage Spring Boot's auto-configuration capabilities
- Handle exceptions gracefully via @ControllerAdvice and @ExceptionHandler
- 利用Spring Boot启动器快速搭建项目
- 正确使用注解(@SpringBootApplication、@RestController、@Service)
- 充分利用Spring Boot的自动配置能力
- 通过@ControllerAdvice和@ExceptionHandler优雅处理异常
Naming Conventions
命名规范
- Use PascalCase for class names (e.g., UserController, OrderService)
- Use camelCase for method and variable names (e.g., findUserById, isOrderValid)
- Use ALL_CAPS for constants (e.g., MAX_RETRY_ATTEMPTS, DEFAULT_PAGE_SIZE)
- 类名使用帕斯卡命名(PascalCase)(例如:UserController、OrderService)
- 方法和变量名使用驼峰式命名(camelCase)(例如:findUserById、isOrderValid)
- 常量使用全大写命名(例如:MAX_RETRY_ATTEMPTS、DEFAULT_PAGE_SIZE)
Java and Spring Boot Usage
Java与Spring Boot 使用规范
- Use Java 17 or later features when applicable (e.g., records, sealed classes, pattern matching)
- Leverage Spring Boot 3.x features and best practices
- Use Spring Data JPA for database operations
- Implement Bean Validation using Jakarta Validation annotations
- 适当时使用Java 17或更高版本的特性(例如:records、密封类、模式匹配)
- 遵循Spring Boot 3.x的特性与最佳实践
- 使用Spring Data JPA进行数据库操作
- 利用Jakarta Validation注解实现Bean校验
Dependency Injection
依赖注入
- Prefer constructor injection over field injection for better testability
- Use @Autowired sparingly; prefer explicit constructor injection
- Leverage Spring's IoC container effectively
- 优先使用构造函数注入而非字段注入,以提升可测试性
- 谨慎使用@Autowired;优先选择显式构造函数注入
- 有效利用Spring的IoC容器
Testing
测试
- Write unit tests using JUnit 5 and Spring Boot Test
- Use MockMvc for testing web layer components
- Implement integration tests with @SpringBootTest
- Use @DataJpaTest for repository layer testing
- 使用JUnit 5和Spring Boot Test编写单元测试
- 使用MockMvc测试Web层组件
- 结合@SpringBootTest实现集成测试
- 使用@DataJpaTest测试仓库层
Performance and Scalability
性能与可扩展性
- Implement Spring Cache abstraction for caching strategies
- Use @Async for non-blocking operations when appropriate
- Optimize database queries using proper indexing and fetch strategies
- 实现Spring Cache抽象以应用缓存策略
- 适当时使用@Async实现非阻塞操作
- 通过合理的索引和查询优化策略提升数据库查询性能
Security
安全
- Implement Spring Security for authentication and authorization
- Use BCrypt for password encoding
- Configure CORS settings as needed for web applications

- 配置合适的日志级别(ERROR、WARN、INFO、DEBUG)
- 利用Spring Boot Actuator实现应用监控与指标采集
API Documentation
API文档
- Use Springdoc OpenAPI for API documentation
