🔐 Spring Security: Using JWT and Basic Auth for Different URL Patterns
- Spring Security allows for the use of both JWT and Basic Auth in the same Spring Boot application for different URL patterns, catering to specific authentication needs.
- Real-world scenarios may require different authentication methods like Basic Auth for public APIs, JWT for client-side authentication, and more, which can be achieved using Spring Security.
- To implement multiple authentication types, developers can create distinct SecurityFilterChain beans for each type, define corresponding authentication providers, and register configurations with @Order to set priority.
- For Basic Authentication on /api/admin/** endpoints, a SecurityFilterChain bean with BasicAuthSecurityConfig class and user details setup along with password encryption can be used.
- JWT Authentication for /api/user/** involves JWT utility classes for token generation, user validation, and filtering setup with JwtAuthFilter and JwtSecurityConfig.
- Dependencies required in pom.xml for Spring Boot 3.x include spring-boot-starter-security and Jwt dependencies for implementing JWT features.
- Testing examples involve using curl commands to access secured endpoints using Basic Auth and JWT token for respective URL patterns.
- Spring Security's flexibility with filter chains and @Order simplifies the process of combining multiple authentication mechanisms in a single Spring Boot application.
- Developers aiming to support backward compatibility with Basic Auth and modern stateless security with JWT can benefit from this dual-authentication approach.
- The article provides a detailed guide on implementing JWT and Basic Auth together in Spring Security, catering to different URL patterns in the Spring Boot application.
