Migrating from Spring Security 5 to Spring Security 6: An Overview

As technology evolves, so does the need for developers to adapt to new frameworks and their features. One such change is the migration from Spring Security 5 to Spring Security 6. While this upgrade can bring enhancements and improved security features, it often introduces challenges, especially for developers who are accustomed to the previous version. One common question that arises during this transition pertains to the HttpSecurity configurations.

In this guide, we'll address a specific migration issue: What is the alternative in Spring Security 6 for certain configurations used in Spring Security 5? We’ll provide a clear solution along with an explanation to ensure a smooth transition.

Understanding the HttpSecurity Configuration

In Spring Security 5, you may have used the following code to configure the HttpSecurity for securing application endpoints:

This configuration essentially does the following:

It restricts access to paths matching /hub/** to users with specific permissions (SOME_LAYER).

It defines a custom access denied handler to manage exceptions.

It ensures that any other request requires authentication.

Lastly, it sets a session management policy to never create sessions.

Transitioning to Spring Security 6

Spring Security 6 introduces a more streamlined way of configuring security, but the way you express these configurations has changed. The equivalent HttpSecurity configuration in Spring Security 6 can be implemented as follows:

Breakdown of Spring Security 6 Configuration

SecurityFilterChain Bean:

In Spring Security 6, you define a SecurityFilterChain bean to contain your HttpSecurity configurations. This is a fundamental shift from the previous approach.

Authorization Requests:

The method authorizeHttpRequests becomes the primary method for managing access control.

Within this method, the requestMatchers function retains its purpose but is now chained more fluently.

The access control logic now requires instantiating a WebExpressionAuthorizationManager to specify your permission requirements.

Access Denied Handling:

The approach remains similar with the exceptionHandling method accepted as an argument in a lambda format, which improves readability.

Session Management:

The session management configuration remains unchanged, but is now applied using fluent syntax.

Conclusion

Migrating to Spring Security 6 may initially seem daunting, particularly regarding HttpSecurity configurations. However, by adopting the new bean structure and familiarizing yourself with the changes in method calls, you can transition seamlessly to this enhanced framework. Familiarizing yourself with these configurations will not only improve your security practices but also ensure that your application remains robust and up-to-date with the latest standards.
