springboot 添加自定义错误页面

1. 书写 configration的bean

@Configuration
public class ErrorConfig  implements ErrorPageRegistrar {

    @Override
    public void registerErrorPages(ErrorPageRegistry registry) {
        // TODO Auto-generated method stub
         ErrorPage error400Page = new ErrorPage(HttpStatus.BAD_REQUEST, "/error400Page");
            ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/error401Page");
            ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/error404Page");
            ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error500Page");
            registry.addErrorPages(error400Page,error401Page,error404Page,error500Page);
    }

    
}

2 书写 controller

@Controller
public class ErrorController {

      @RequestMapping(value = "/error400Page")
        public String error400Page(Model model) {
          model.addAttribute("code","400错误");
            model.addAttribute("msg","......");  
          return "404";
        }
        @RequestMapping(value = "/error401Page")
        public String error401Page(Model model) {
            model.addAttribute("code","401错误");
            model.addAttribute("msg","......");
            return "404";
        }
        @RequestMapping(value = "/error404Page")
        public String error404Page(Model model) {
            model.addAttribute("code","404错误");
            model.addAttribute("msg","找不到页面......");
            return "404";
        }
        @RequestMapping(value = "/error500Page")
        public String error500Page(Model model) {
             model.addAttribute("code","500错误");
             model.addAttribute("msg","服务器参数错误......");
            return "404";
        }
}
