1、在控制器添加异常处理@Exception'Handle（异常类名）public String handle（类名）{ return “异常的页面”；}发生指定异常时跳转
2、这种异常处理方式并不能处理404请求错误，需要在web.xml配置错误页面<error-page> <exception-type>java.lang.Throwable</exception-type> <location>/WEB-INF/views/error/404.jsp</location> </error-page>
4、@RequestMapping(value="/delete",method=RequestMethod.GET,produces="text/html;charset=UTF-8") public String delete(RedirectAttributes ra,String id,HttpServletRequest request){
6、return "redirect:1/dealerList?jyxkz="+StringUtils.nullTo(d.get("jyxkz"))+"&name="+StringUtils.nullTo(d.get("name"))
