Spring Boot Remove Whitelabel Error Page for web application
提问by Manu
I have a spring boot web application,which I am deploying as a war file in tomcat. I do not want the user to be displyed the white-label error page. I have progressed a bit on this, but need to re-direct the same to error page.
我有一个 spring boot web 应用程序，我将它部署为 tomcat 中的一个 war 文件。我不希望用户显示白标错误页面。我在这方面取得了一些进展，但需要将其重新定向到错误页面。
The below code is /error white-label error page is custom error message. But i want it to be re-directed to a error.jsp or error.html available under the template folder in resources of my web application. I tried changing the @RestControllerto @Controllerwith no luck.
下面的代码是 /error 白标错误页面是自定义错误消息。但我希望它被重定向到我的 web 应用程序资源中模板文件夹下可用的 error.jsp 或 error.html。我尝试将@RestController更改为@Controller，但没有运气。
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";
}
}

Turn off whitelabel error pages in application.properties
关闭白标错误页面 application.properties
server.error.whitelabel.enabled=false
server.error.whitelabel.enabled=false

You can write your own exception handler in Spring and redirect to the error page
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
Below one is to handler the Exceptionand its sub classes
下面一个是处理Exception和它的子类
@ExceptionHandler(Exception.class)
public ModelAndView globalExceptionHandler(Exception e) {
ModelAndView modelAndView = new ModelAndView("error");
modelAndView.addObject("message", e.getMessage());
return modelAndView;
}
You can write any number of exception handlers in controller, also narrow the exception you need in handlers, return appropriate error page.
您可以在控制器中编写任意数量的异常处理程序，还可以缩小处理程序中所需的异常范围，返回适当的错误页面。
Have a look at the documentation
