Multi basic auth with spring security

To implement multi basic authentication with Spring Security, you can follow these steps:

  1. Configure Spring Security: Start by adding the necessary dependencies to your project's build file. Then, create a security configuration class that extends the WebSecurityConfigurerAdapter class. Override the configure(HttpSecurity http) method to specify the security rules for your application.

  2. Configure Multiple Authentication Providers: In the configure(AuthenticationManagerBuilder auth) method of your security configuration class, configure multiple authentication providers. Each provider should be responsible for a specific type of authentication, such as basic authentication or form-based authentication.

  3. Define Authentication Filters: Create authentication filters for each type of authentication you want to support. These filters will intercept incoming requests, extract the necessary authentication information, and attempt to authenticate the user.

  4. Implement Authentication Providers: Implement the AuthenticationProvider interface for each authentication method you want to support. This interface has a single method, authenticate(Authentication authentication), which should return a fully authenticated Authentication object if the authentication is successful.

  5. Configure Authentication Manager: In the configure(AuthenticationManagerBuilder auth) method, use the authentication providers you implemented in the previous step to configure the authentication manager.

  6. Configure Access Rules: In the configure(HttpSecurity http) method, specify access rules for different URLs or paths in your application. You can use the antMatchers() method to define URL patterns and the hasRole() method to specify the required roles for accessing those URLs.

  7. Enable HTTP Basic Authentication: Use the httpBasic() method in the configure(HttpSecurity http) method to enable HTTP Basic Authentication. This will add a BasicAuthenticationFilter to the filter chain, which will handle basic authentication requests.

  8. Test the Multi Basic Authentication: Finally, test your multi basic authentication implementation by sending requests that require basic authentication. Make sure you include the necessary authentication headers in your requests, such as "Authorization: Basic base64(username:password)".

By following these steps, you should be able to implement multi basic authentication with Spring Security in your application.
