How to show custom 404 page when user enters invalid URL in spring boot application?
提问by ashishjmeshram
I am using java config in spring boot, spring security application. I have configured the error controller as below. But whenever, I enter an invalid URL it goes to error.jsp, which is configured to handle the errors in the application:
我在 spring 启动、spring 安全应用程序中使用 java 配置。我已按如下方式配置了错误控制器。但是每当我输入一个无效的 URL 时，它会转到error.jsp，它被配置为处理应用程序中的错误：
@Controller
public class AppErrorController implements ErrorController {
private static final String PATH = "/error";
@RequestMapping(value = "/pageNotFound", method = { RequestMethod.GET, RequestMethod.POST })
public String pageNotFound() {
return "pageNotFound";
}
@RequestMapping(value = "/accessDenied", method = { RequestMethod.GET, RequestMethod.POST })
public String accessDenied() {
return "accessDenied";
}
@RequestMapping(value = PATH)
public String error() {
return "error";
}
@Override
public String getErrorPath() {
return PATH;
}
}
web.xml
网页.xml
<error-page>
<error-code>404</error-code>
<location>/pageNotFound</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/error</location>
</error-page>
404 is never thrown when the invalid URL is entered.
输入无效 URL 时，永远不会抛出 404。
Also, I am not using embedded tomcat. I am deploying war to the external tomcat. I have this in my application.ymlfile:
另外，我没有使用嵌入式 tomcat。我正在将War部署到外部 tomcat。我的application.yml文件中有这个：
server:
error:
whitelabel:
enabled: false
Below is the log in case if I enter a invalid URL. There is no error. It just redirects to /errorin case of invalid URL:
如果我输入了无效的 URL，下面是登录情况。没有错误。它只是/error在 URL 无效的情况下重定向到：

回答by Ali Dehghani
First off, define an exception for each especial HTTP error you're going to handle. Here i'm just defining one for handling 404 Not Foundcase:
首先，为您要处理的每个特殊 HTTP 错误定义一个异常。在这里，我只是定义了一个处理404 Not Found案例：
public class NotFoundException extends RuntimeException {}
To replace the default Spring Boot's error handling mechanism completely, we can implement ErrorController. Instead of just implementing the ErrorController, here i'm extending AbstractErrorController, which implements the ErrorControllerand provides some auxiliary methods like getStatus().
要完全替换默认的 Spring Boot 错误处理机制，我们可以实现ErrorController. 而不是仅仅实现ErrorController，这里我正在扩展AbstractErrorController，它实现了ErrorController并提供了一些辅助方法，比如getStatus()。
Anyway, the basic idea is to handle all errors using an endpoint, say /error, and throw those pre-defined exceptions in case of their corresponding HTTP status codes:
无论如何，基本思想是使用端点处理所有错误，例如/error，并在对应的 HTTP 状态代码的情况下抛出这些预定义的异常：
@Controller
public class CustomErrorController extends AbstractErrorController {
private static final String ERROR_PATH= "/error";
@Autowired
public CustomErrorController(ErrorAttributes errorAttributes) {
super(errorAttributes);
}
/**
* Just catching the {@linkplain NotFoundException} exceptions and render
* the 404.jsp error page.
*/
@ExceptionHandler(NotFoundException.class)
public String notFound() {
return "404";
}
/**
* Responsible for handling all errors and throw especial exceptions
* for some HTTP status codes. Otherwise, it will return a map that
* ultimately will be converted to a json error.
*/
@RequestMapping(ERROR_PATH)
public ResponseEntity<?> handleErrors(HttpServletRequest request) {
HttpStatus status = getStatus(request);
if (status.equals(HttpStatus.NOT_FOUND))
throw new NotFoundException();
return ResponseEntity.status(status).body(getErrorAttributes(request, false));
}
@Override
public String getErrorPath() {
return ERROR_PATH;
}
}
Of course, this solution is only suitable for Traditional Deployment. If you're planning to use an Embedded Servlet Container, you're better off defining an EmbeddedServletContainerCustomizer.
当然，这个方案只适用于传统部署。如果您打算使用嵌入式 Servlet 容器，最好定义一个EmbeddedServletContainerCustomizer.

Whould you like to add this @Beanto your spring application config, like this :
你想把它添加@Bean到你的 spring 应用程序配置中，像这样：
@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/error404.html");
container.addErrorPages(error404Page);
}
};
}
and put error404.htmlin your static folder.
并放入error404.html您的静态文件夹中。
