如何正确的使用spring boot拦截器

package com.example.interceptor;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;public class IndexInterceptor implements HandlerInterceptor{  @Override  public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)      throws Exception {    System.out.println(">>>IndexInterceptor>>>>>>>在整个请求结束之后被调用，也就是在DispatcherServlet 渲染了对应的视图之后执行（主要是用于进行资源清理工作）");  }  @Override  public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)      throws Exception {    System.out.println(">>>IndexInterceptor>>>>>>>请求处理之后进行调用，但是在视图被渲染之前（Controller方法调用之后）");  }  @Override  public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception {     System.out.println(">>>IndexInterceptor>>>>>>>在请求处理之前进行调用（Controller方法调用之前）");     // 只有返回true才会继续向下执行，返回false取消当前请求     return true;  }}
