Introduction

If you're developing a Spring MVC application and implementing security features, you might run into a frustrating issue where pages are accessible without proper authentication. This can be particularly concerning in a production environment where sensitive data needs to be protected. In this guide, we will explore a common problem: Spring Security does not restrict access. We will break down the issue and present a straightforward solution to help you get your application secured.

Problem Overview

When setting up your Spring MVC project with security, you might find that paths intended to be protected (like /product or /test) are still accessible publicly. Despite configuring your security settings to enforce authentication, it may seem like the authentication filters are not being applied. You may have already checked that your configuration methods are being executed by the Spring context, yet the expected security behavior is absent.

Example of Security Configuration

Here’s an example of a standard SecureConfig configuration that may not seem to work as intended:

In this configuration, the intention is that any request made to the application should be authenticated.

However, users may find they can access any page without being required to log in.

Diagnosing the Issue

Dependency Considerations

Before jumping into solutions, ensure that your dependencies are correctly set. Here are the right dependencies for Spring Security:

Importance of Filter Initialization

You may think that you've configured everything correctly, but one crucial aspect might be missing: the Spring Security Filter chain isn't set up correctly. This can occur if you're not explicitly initializing the security filters in your application context.

Solution

To ensure that Spring Security is applied correctly and the filters are operational, you need to add the following class:

Explanation of the Solution

Extend AbstractSecurityWebApplicationInitializer:

By creating this class, you are informing the Spring framework to register the SpringSecurityFilterChain, which is essential for handling the security features.

Registering the Filter:

The absence of this class can lead to Spring Security filters not being invoked, resulting in unrestricted access to your application.

Conclusion

In summary, the issue of Spring Security not denying access to secured routes in your application can often stem from not initializing the security filter correctly. By adding the SpringSecurityInitializer class, you can help the Spring framework properly manage security functionalities. Always remember to check your dependencies and ensure proper configuration to safeguard your application effectively.

If you find that you are still having issues after following this guide, consider revisiting your security configuration and ensuring that no other aspects of your application are conflicting with the security filters.

By implementing these changes, your application will be better equipped to handle security, ensuring that users can only access permitted resources.
