In my Spring Boot application, I'm trying to configure custom error pages, for example for 404, I have added a following Bean to my application configuration:
@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
container.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/404.html"));
}
};
}
Also, I have created a following simple Thymeleaf template:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<head>
<title>404 Not Found</title>
<meta charset="utf-8" />
</head>
<body>
<h3>404 Not Found</h3>
<h1 th:text="${errorCode}">404</h1>
<p th:utext="${errorMessage}">Error java.lang.NullPointerException</p>
<a href="/" th:href="@{/}">Back to Home Page</a>
</body>
</html>
and added it into /resources/templates/
folder. Right now on the 404 error I can see only white screen.
What am I doing wrong and how to correctly setup my 404 page? Also, is it possible to use templates and not only static pages for custom error pages?
