How to show custom 404 page when user enters invalid URL in spring boot application?

java spring spring-security spring-boot

Solution 1

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 Found case:

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 ErrorController and provides some auxiliary methods like 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:

@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.

Solution 2

Whould you like to add this @Bean to your spring application config, like this :

@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.html in your static folder.

Reference : http://www.sporcic.org/2014/05/custom-error-pages-with-spring-boot/

Solution 3

Here you go 

@RestController
public class RestErrorController implements ErrorController{

private static final String PATH = "/error";

@Autowired
private ErrorAttributes errorAttributes;

@RequestMapping(value=PATH,method=RequestMethod.GET)
public ApiErrorExtended error(HttpServletRequest request, HttpServletResponse response){
     return new ApiErrorExtended( response.getStatus(),getErrorAttributes(request, true));
}

private Map<String, Object> getErrorAttributes(HttpServletRequest request, boolean includeStackTrace) {
    RequestAttributes requestAttributes = new ServletRequestAttributes(request);
    return errorAttributes.getErrorAttributes(requestAttributes, includeStackTrace);
}  

public String getErrorPath() {
    return PATH;
} 
}

This is my rest error controller. You can modify it to return whatever u want.

    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:

    @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

    <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.

    Also, I am not using embedded tomcat. I am deploying war to the external tomcat. I have this in my application.yml file:

    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 /error in case of invalid URL:

    Did u try removing <error-page> <error-code>404</error-code> <location>/pageNotFound</location> </error-page> <error-page> <error-code>500</error-code> <location>/error</location> </error-page> all together? I believe 404 will be resolved by default. Anyways i am gonna take a closer look at my config. when i get back to my pc.

    What excpetion do you get when your remove the error pages in your web.xml.Probably Spring is throwing another exception wihich is not 404 due to a setup error. Post the error being displayed on tomcat`s default error page

    I have tried that also. Does not work. Actually, it used to work in other non spring boot apps.
