Hi, In a plain Spring Boot application (without Wicket-SpringBoot) you can do it with ErrorPageRegistrar:
import org.springframework.boot.web.servlet.ErrorPage; import org.springframework.boot.web.servlet.ErrorPageRegistrar; import org.springframework.boot.web.servlet.ErrorPageRegistry; import org.springframework.http.HttpStatus; public class MyErrorPageRegistrar implements ErrorPageRegistrar { @Override public void registerErrorPages(final ErrorPageRegistry registry) { registry.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, MyApplication.PAGE_NOT_FOUND_MOUNT_PATH)); } } In MySpringContext.java: @Bean public ErrorPageRegistrar errorPageRegistrar(){ return new MyErrorPageRegistrar(); } In MyApplication.java: mountPage(PAGE_NOT_FOUND_MOUNT_PATH, Error404Page.class); Martin Grigorov Wicket Training and Consulting Looking for a remote position with Wicket ?
