Resolving Frequent Custom Provider Calls with Spring 6 Basic Authentication

Upgrading a web application can often introduce unexpected challenges, especially when it comes to frameworks as complex as Spring. One common issue developers encounter when upgrading from Spring Boot 2 to Spring Boot 3, which uses Spring 6, is the behavior of authentication providers. In this guide, we’ll explore a specific problem: why a custom authentication provider is called on every request when using Basic Authentication—and how to solve it!

The Problem

After modifying your security configuration to accommodate the Spring 6 changes, you might find that your custom authentication provider is being invoked on every single request. This differs from the previous behavior in Spring Boot 2, where it would only be called once per session. The increased frequency of calls to the authentication provider can lead to heavy database traffic and performance issues, which is particularly concerning in a production environment.

Overview of the Security Configuration

The following sample code snippet illustrates a typical security configuration that leads to this issue:

In this configuration, the httpBasic() method is being utilized, which is critical to understanding the behavior of authentication calls.

Behavior Comparison

ConfigurationBehavior.formLogin()1x Login / Provider Call.httpBasic()1x Login per Session / 1x Provider Call per RequestWhen using form login, your provider is called just once when the user logs in. However, Basic Authentication leads to the provider being triggered on every request, creating a significant overhead.

The Solution

To revert to the original session behavior similar to what you experienced with Spring Boot 2, you can adjust the session management policy within your security filter chain. This configuration limits when a new session will be created and can effectively help mitigate the excessive calls to the custom authentication provider.

Steps to Restore Old Behavior

Here’s how you can modify your security configuration to fix the issue:

Locate the filterChain method in your SecurityConfig class

Add session management settings to specify the session creation policy.

Here’s the updated code snippet:

This adjustment tells Spring Security to only create a session if one is needed, thus ensuring that your custom authentication provider doesn’t get called on every request.

Key Takeaways

Make sure to include session management in your Spring Security configuration when using Basic Authentication.

Use SessionCreationPolicy.IF_REQUIRED to prevent the custom provider from executing unnecessarily and reduce database traffic.

Conclusion

Upgrading to new versions of frameworks like Spring can often reveal intricate bugs and unexpected behaviors. By fine-tuning your security configurations, such as adjusting session management, you can restore expected behaviors and enhance performance in your application.

If you've faced a similar challenge when upgrading your applications, implementing the session management changes we've discussed will help you address the inefficiencies related to your authentication provider. Happy coding!
