使用两种方式，实现拦截http请求的后台运行时间。

废话不多说直接上代码

/** * Http请求时间统计 * 拦截所有请求 */public class HttpRquestTimeInterceptor extends HandlerInterceptorAdapter {    ThreadLocal
    
      localThread = new ThreadLocal
     
      ();    @Override    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {        //线程方式        localThread.set(System.currentTimeMillis());        //request方式        request.setAttribute("_startTime", System.currentTimeMillis());        return true;    }    @Override    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {        Long endTime = System.currentTimeMillis();        System.out.println(request.getServletPath() + " >> http请求结束线程：" + (endTime - localThread.get()));        Long startTime = (Long)request.getAttribute("_startTime");        System.out.println(request.getServletPath() + " >> http请求结束:" + (endTime - startTime));    }}
     
    

Spring 配置
