Customizing Whitelabel error in Thymeleaf

Spring Boot by default installs a ‘whitelabel’ Error page that you see in a browser client if you encounter a server error. You can customize it as needed based on your view technology, find the below post to override it in thymeleaf.

Step 1: Disable default error page in application.properties

#Disabling Default while lable error
server.error.whitelabel.enabled=false

Step 2: Adding a custom error page (error.html)

Overriding the error page with your own depends on the templating technology that you use. Here since I am using Thymeleaf, i have added error.html template.

Step 3: Configure pom.xml

Just add web, thymeleaf starter to your pom or gradle file.

Step 4: Launch as Spring boot application (CustomwhitelabelErrorApplication.java)

package com.candidjava.customwhitelabel_error;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CustomwhitelabelErrorApplication {

 public static void main(String[] args) {
  SpringApplication.run(CustomwhitelabelErrorApplication.class, args);
 }

}
