1.定义全局异常处理器，为全局的异常，如出现将调用 error.JSP

     
     	
      		
       			
        			
        
         error
        		
       	
      
     

　

@RequestMapping("hello.do")	public String excute(@ModelAttribute("username") String username,String pwd,Model model){		model.addAttribute("name","TOM");		//有可能抛出异常		String s = null;		s.length();		return "hello";	}

　2.定义局部异常处理，Controller里面的请求捕获

　

//局部异常处理，当前Controller发生错误调用dateerror.jsp	@ExceptionHandler	public String handleException(		HttpServletRequest request,		Exception ex){		request.setAttribute("error", ex);		return "dateerror";	}
