Spring Security: Why Aren\'t My Multiple HTTP Configurations Working?

Spring Security: Multiple HTTP Configurations not Working

This article explores a Spring Security issue where multiple HTTP configurations are not functioning as expected.

Problem

A developer attempted to establish different login pages and protected URL sets using multiple WebSecurityConfigurerAdapter classes and encountered an implementation problem. The security for one group of URL patterns was working correctly, but the other group was not being secured, resulting in no redirection to the login page.

Solution

To solve this issue, the developer needed to ensure the proper order of execution for the WebSecurityConfigurerAdapter configurations. Spring Security processes configurations in the order they are declared. In this case, the first configuration restricted access only to a specific URL pattern (/admin/), while the second configuration aimed to secure all other URLs. However, since the first configuration matched all URLs (/), it took precedence and effectively prevented the second configuration from being applied.

Proper Configuration

@Configuration
@Order(1)
public static class ProviderSecurity extends WebSecurityConfigurerAdapter {

    // Configure security for /admin/**

}

@Configuration
@Order(2)
public static class ConsumerSecurity extends WebSecurityConfigurerAdapter {

    // Configure security for /consumer/**

}

By assigning an @Order value of 2 to the ConsumerSecurity configuration, we ensure that it is processed after the ProviderSecurity configuration. This way, it can restrict access to the /consumer/** URLs as intended.
