Springboot拦截器配置
@Component

@Reference(interfaceClass = UserService.class,version = "1.0.0",check = false,timeout = 15000)//使用了dubbo,可以不加
private UserService userService;
//preHandler方法实在连接到达前进行判断,false为连接拒绝,true为连接通过
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

/*
postHandler用于对拦截信息处理完毕后进行其他操作
需要perHandler方法的返回值为true时才能执行
通肠胃preHandler通过后,就会执行
*/

HandlerInterceptor.super.postHandle(request, response, handler, modelAndView);
}
/* 需要perHandler方法的返回值为true时才能执行
该方法主要用于清理资源等
它将在整个请求完成之后，也就是DispatcherServlet渲染了视图执行后,才会运行
*/
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
HandlerInterceptor.super.afterCompletion(request, response, handler, ex);
