请求出现 想要跳转到错误页面

就需要对springmvc进行配置

方法1:基于xml的配置

springmvc.xml配置类

<!--配置基于xml的异常映射--><bean id="simpleMappingExceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <!--配置异常和对应页面的映射--> <property name="exceptionMappings" > <props> <prop key="java.lang.Exception">erroe</prop> </props> </property></bean>

2.方法2：基于@ControllerAdvice

@ControllerAdvicepublic class ExceptionResolver { @ExceptionHandler(value = NullPointerException.class)public ModelAndView nullPointerExceptionResovler(NullPointerException e, HttpServletRequest request, HttpServletResponse response) throws IOException { String viewName="erroe"; return commonReslover(viewName,response,request,e); } private ModelAndView commonReslover(String viewName,HttpServletResponse response,HttpServletRequest request,Exception e) throws IOException { boolean judgeResult = CrowdUtil.judgeRequestType(request); if(judgeResult){ ResultEntity<Object> resultEntity=ResultEntity.failed(e.getMessage()); //转成gson对象 Gson gson=new Gson(); response.getWriter().write(gson.toJson(resultEntity)); return null; } ModelAndView modelAndView=new ModelAndView(); modelAndView.addObject("exception",e); modelAndView.setViewName(viewName); return modelAndView; }}
