spring boot 下 500 404 错误页面处理

<bean
  class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
  <property name="exceptionMappings">
   <props>
    <prop key="org.apache.shiro.authz.UnauthenticatedException">pages/403</prop>
    <prop key="org.apache.shiro.authz.UnauthorizedException">pages/403</prop>
    <prop key="org.apache.shiro.authc.LockedAccountException">pages/locked</prop>
    <prop key="java.lang.Throwable">pages/500</prop>
   </props>
  </property>
 </bean>

1. 

先设置dispatcherServlet

 @Bean
 public ServletRegistrationBean dispatcherRegistration(DispatcherServlet dispatcherServlet) {
     ServletRegistrationBean registration = new ServletRegistrationBean(
             dispatcherServlet);
     dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
     return registration;
 }

@ControllerAdvice
public class GlobalControllerExceptionHandler {
 public static final String DEFAULT_ERROR_VIEW = "pages/404";

    @ExceptionHandler(value = NoHandlerFoundException.class)
    public ModelAndView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", e);
        mav.addObject("url", req.getRequestURL());
        mav.setViewName(DEFAULT_ERROR_VIEW);
        return mav;
    }
}

2. 集成ErrorController 

@Controller
public class MainsiteErrorController implements ErrorController {

 private static final String ERROR_PATH = "/error";
 
 @RequestMapping(value=ERROR_PATH)
    public String handleError(){
        return "pages/404";
    }
 
 @Override
 public String getErrorPath() {
  // TODO Auto-generated method stub
  return ERROR_PATH;
 }

}
