Spring Boot删除Web应用程序的Whitelabel错误页面

Question

我有一个spring boot web应用程序，我将其部署为tomcat中的war文件。我不希望用户显示白标错误页面。我已经取得了一些进展，但需要将其重新指向错误页面。

以下代码是/ error白标错误页面是自定义错误消息。但是我想将它重定向到我的Web应用程序资源中的模板文件夹下的error.jsp或error.html。我尝试将 @RestController 改为 @Controller 而没有运气。

import org.springframework.boot.autoconfigure.web.ErrorController;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class CustomErrorController implements ErrorController {

    private static final String PATH = "/error";

    @RequestMapping(value = PATH)
    public String error() {
        return "Unexpected error has happened.Please contact administrator!!!";
    }

    @Override
    public String getErrorPath() {
        System.out.println("-- Error Page GET --");
            return "error";
    }

}

Answer 1

关闭application.properties

中的whitelabel错误页面

server.error.whitelabel.enabled=false

Answer 2

您可以在Spring中编写自己的异常处理程序并重定向到错误页面

下面是处理Exception及其子类

@ExceptionHandler(Exception.class)
public ModelAndView globalExceptionHandler(Exception e) {
    ModelAndView modelAndView = new ModelAndView("error");
    modelAndView.addObject("message", e.getMessage());
    return modelAndView;
}

您可以在控制器中编写任意数量的异常处理程序，也可以缩小处理程序中需要的异常，返回相应的错误页面。
