 1、页面跳转形式；2、ajax；3、统一返回异常的形式

异常处理web请求或ajax请求

@ControllerAdvicepublic class GlobalExceptionHandler(){  @ExceptionHandler(value=Exception.class)  @ResponseBody  private Object exceptionHandler(HttpServletRequest req,Exception e) {     e.printStackTrace();    if(isAjax(req)){        return RestltBean();//返回异常结果类    }else{        ModeAndView mav = new ModeAndView();           mav.addObject("Exception",e);        mav.addObject("url",req.getRequestURL());        mav.setViewName("error");        return mav;    }  　 } }

 

判断是否是ajax请求

 

public static Boolean isAjax(HttpServletRequest req){  return req.getHeader("X-Requested-With") != null && "XMLHttpRequest".equals(req.getHeader("X-Requested-With").toString());}
