Disable Whitelabel Error Page and Free /error Endpoint
When developing a Spring Boot application, you may encounter the default “Whitelabel Error Page” when an error occurs. This generic error page is Spring Boot’s default behavior when no custom error handling is configured. While useful during development, the Whitelabel Error Page is not suitable for production applications, as it provides little information to end-users. In this article, we will explore several approaches to removing the Whitelabel Error Page and implementing a more user-friendly error handling solution.

Understanding Whitelabel Error Page
The Whitelabel Error Page is a default error page generated by Spring Boot when an unhandled exception occurs in your application. This error page provides a basic HTML representation of the error details, including the HTTP status code and a brief error message. The Whitelabel Error Page is useful during development as it helps in identifying and debugging errors quickly. However, in production environments, it is recommended to customize the error handling to provide more detailed and user-friendly error messages.
Disabling Whitelabel Error Page
To disable the White’label Error Page, you can use one of the following methods:
1. Property File
You can disable the White’label Error Page by setting the server.error.whitelabel.enabled property to false in your application’s application.properties or application.yml file:
propertiesserver.error.whitelabel.enabled=false
yamlserver:
error:
whitelabel:
enabled: false
2. Excluding ErrorMvcAutoConfiguration
Another way to disable the White’label Error Page is to exclude the ErrorMvcAutoConfiguration bean from auto configuration. This can be done by adding the following configuration to your application.properties or application.yml file:
propertiesspring.autoconfigure.exclude=org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration
yamlspring:
autoconfigure:
exclude: org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration
Customizing Error Handling
Disabling the Whitelabel Error Page is only the first step in customizing error handling in Spring Boot. You can create a custom error page by creating a dedicated controller class to handle error handling. Here’s an example:
java@Controller
public class ErrorController implements org.springframework.boot.web.servlet.error.ErrorController {
@RequestMapping("/error")
public String handleError(HttpServletRequest request) {
Integer statusCode = (Integer) request.getAttribute(RequestDispatcher.ERROR_STATUS_CODE);
if (statusCode == HttpStatus.NOT_FOUND.value()) {
return "error/404";
} else if (statusCode == HttpStatus.INTERNAL_SERVER_ERROR.value()) {
return "error/500";
} else {
return "error/generic";
}
}
@Override
public String getErrorPath() {
return "/error";
}
}
Creating a Custom Error Page
To create a custom error page, you need to add a new HTML template file to the src/main/resources/templates directory of your Spring Boot project. This file will be used to render the error page. For example, you can create a 404.html file with the following content:
html<!DOCTYPE html>
<html>
<head>
<title>Error 404 - Page Not Found</title>
</head>
<body>
<h1>Error 404 - Page Not Found</h1>
<p>The requested page could not be found.</p>
</body>
</html>
Handling Exceptions Globally
To handle exceptions globally, you can create a custom exception handler. Here’s an example:
java@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(Exception.class)
public String handleException(Exception e) {
return "error/generic";
}
}
Conclusion
In this article, we have seen how to disable the White’label Error’Page and implement a custom error handling solution in Spring Boot. We have covered various methods to disable the Whitelabel Error’Page, including using properties files and excluding auto configuration beans. We have also seen how to create a custom error page and handle exceptions globally. By following these steps, you can provide more user-friendly and application-specific error responses when exceptions occur in your Spring Boot application.

Transitioning to a new website host can be challenging yet rewarding for administrators and business owners. As technology evolves and website needs grow, selecting the right hosting provider is crucial. This decision impacts website performance, security, and overall user experience. In 2025, several key considerations will guide individuals and organizations in making this transition smoothly and efficiently.
Understanding the Importance of WordPress Hosting
In 2025, WordPress hosting options will continue to offer a variety of features catering to different website sizes and traffic levels. Engaging with a host that excels in WordPress management ensures that essential updates and security patches are implemented effectively, allowing site owners to concentrate on content creation and user engagement. Liquid Web is an excellent host for WordPress due to its options for businesses of all sizes. Its managed services act as an extension of your team by handling updates, security, and performance. With 24/7 expert support and optimized infrastructure, it ensures faster load times, high uptime, and a hassle-free experience for website owners.
Evaluating Performance and Uptime Guarantees
Performance metrics play a significant role in selecting a new website host. A reliable hosting provider should guarantee high uptime rates, which refer to when a site remains operational without interruptions. A provider offering a 99.9% uptime guarantee helps ensure that users can access the website consistently, reducing the risk of lost visitors and potential revenue.
Site speed is another essential performance indicator. A host that optimizes loading times enhances user experience, as faster websites tend to have higher engagement and lower bounce rates.
Assessing Customer Support Options
Strong customer support is vital when transitioning to a new website host. Hosting providers should offer 24/7 customer service, allowing users to resolve issues swiftly. Knowledgeable representatives, available through phone, chat, or email support, can greatly reduce stress during the migration process.
Users should consider researching the reputation of potential hosting providers regarding support quality. A responsive support team can make a significant difference in navigating any difficulties that may arise during the transition.
Considering Scalability and Flexibility
In an ever-changing digital landscape, scalability and flexibility are essential for a long-term hosting solution. As website traffic levels fluctuate, having a host that allows easy upgrades without downtime can be beneficial. Choosing a provider offering upgraded plans and additional resources ensures site owners can adapt to growth seamlessly.
Flexibility in hosting options is equally essential. With the emergence of various content management systems and tools, selecting a host that supports different applications and integrations is vital. This adaptability facilitates incorporating new features or functionalities that enhance website operations in the future.
Reviewing Security Features
Security must be balanced when transitioning to a new website host. Cyber threats increasingly target websites, making a robust security protocol a necessary consideration. Prospective hosting providers should offer features such as SSL certificates, firewalls, and daily backups to ensure that websites and user data remain secure.
Additionally, it is crucial to understand how a hosting provider manages security updates. Regular patches and updates are vital for maintaining site integrity and protecting against vulnerabilities. A host committed to proactive security measures can provide peace of mind during the transition process.
Transitioning to a new website host in 2025 involves carefully considering various factors impacting site performance and user experience. Website owners can make informed decisions by understanding the advantages of specialized hosting, evaluating performance guarantees, and assessing customer support options.
Security features and scalability also play essential roles in ensuring the chosen host meets long-term needs. With thorough research and evaluation, a smooth transition can lead to enhanced website functionality and a better overall user experience.
