Spring 4异常处理：没有合适的参数解析器

通过在请求本身中传递自定义参数来解决该问题。

代码如下：

控制者

@RequestMapping(method = RequestMethod.GET, value = "/exception2")public String getException1(ModelMap model, @CRequestParam("p") String p, HttpServletRequest request) {  System.out.println("Exception 2 " + p);  request.setAttribute("p", p);  throw new CustomGenericException("1", "2");}

异常处理程序

@ExceptionHandler(CustomGenericException.class)public ModelAndView handleCustomException(CustomGenericException ex, HttpServletRequest request) {  ModelAndView model2 = new ModelAndView("error/generic_error");  model2.addObject("exception", ex);  System.out.println(request.getAttribute("p"));  System.out.println("CustomGenericException  ");  return model2;}
