spring|spring web|拦截器、过滤器、aop
基于spring-boot 4.0.x
五大核心组件
- ●Filter 过滤器（Servlet层）| 管原始HTTP报文，Spring容器之外
- ●Interceptor 拦截器（SpringMVC层）|管Controller接口请求，做登录/Token拦截
- ●AOP 切面（Bean方法层）|管Java方法执行，做业务增强（日志/事务/耗时）
- ●Request/ResponseBodyAdvice（MVC消息层）| 只修饰、不拦截、不中断请求
- ●ControllerAdvice 全局异常（MVC兜底层） | 只修饰、不拦截、不中断请求
