Spring boot Restful 拦截

1、过程

如图filter(过滤器) -> interceptor(拦截器)->ControllerAdvice（自定义异常处理机制）->Aspect(切面)->Controoler(控制器) 

2、过滤器

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)

只能拿到请求和相应，拿不到具体的控制器信息

3、拦截器

public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)

能拿到控制器，但拿不到方法参数

//成功执行后
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
			ModelAndView modelAndView)
//finally
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)

4、切面

通过@Around，ProceedingJoinPoint可以获取控制器的相应信息

public Object handleControllerMethod(ProceedingJoinPoint pjp)
