How to Fix: Spring Boot Remove Whitelabel Error Page

The white label error page is a common issue in Spring Boot applications, especially when trying to remove it. This error occurs when the application cannot find a controller mapping for the requested URL.

This issue affects developers who are using Spring Boot and have not properly configured their controllers or mappings.

💡 Why You Are Getting This Error

• The primary cause of this error is that the @RestController annotation is missing on the IndexController class. This annotation is required to indicate that the class contains RESTful controllers.
• Another possible cause is that the controller mapping for the '/error' URL is not correctly defined or is missing altogether.

✅ Best Solutions to Fix It

🎯 Final Words

To resolve this issue, enable annotation-based mapping by adding the @RestController annotation to the IndexController class. Additionally, update the controller mapping for the '/error' URL using the @ExceptionHandler annotation or a custom error handling mechanism. If the issue persists, check for other controllers or mappings that might be interfering with the '/error' URL and ensure all necessary dependencies and configurations are included in the application.
