How to return custom error message in Spring Boot for /error page
Question
I have a spring boot project and some UI with thymeleaf. I have designed a /error page instead of the White level error, and it is working as expected. However I need to pass some string to /error and display that string in the error page. I am wondering how to do that.
This is my /error page :
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Error Occurred.</title>
<link rel="stylesheet" type="text/css" th:href="@{/css/styles.css}">
</head>
<body>
<th:block th:include="/_header"></th:block>
<th:block th:include="/menu"></th:block>
<div class="page-title">Error!</div>
<h3 style="color: red;">Sorry! Something went wrong !</h3>
</body>
</html>
Error method :
@RequestMapping("/error")
public String error() {
logger.info("Error Page called...");
return "error";
}
Instead of the error message Sorry! Something went wrong ! Sorry! Something went wrong ! I want to send something specific from the caller. How to do that.

You can do it this way
Template
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Error Occurred.</title>
<link rel="stylesheet" type="text/css" th:href="@{/css/styles.css}">
</head>
<body>
<th:block th:include="/_header"></th:block>
<th:block th:include="/menu"></th:block>
<div class="page-title">Error!</div>
<h3 style="color: red;" th:text="${errorMsg}">Sorry! Something went wrong !</h3>
</body>
</html>
// Controller
@RequestMapping("/error")
public String error() {
logger.info("Error Page called...");
mmodel.addAttribute("errorMsg", "Custom Error Message");
return "error";
}

I could find a simple way at last using redirectAttributes.addFlashAttribute .
Here is my some controller method from where I am redirecting the /error with reason :
String errorMsg = "Cart is Empty. Add some products to Cart." ;
CustomErrorMessage error = new CustomErrorMessage(errorMsg);
redirectAttributes.addFlashAttribute("errorForm", error);
return "redirect:/error";
Ans here is my error page :
<div class="page-title">
<h3 style="color: red">Sorry! Something went wrong !</h3>
<th:block th:if="${errorForm == null}">
<h4>Go to Home Page : <a th:href="@{/}">Home</a></h4>
</th:block>
<th:block th:if="${errorForm != null}">
<div><ul><li>Error reason : <span th:utext="${errorForm.errorMsg}"></span></li></ul></div>
<h4>Go to Home Page : <a th:href="@{/}">Home</a></h4>
</th:block>
</div>
