How can you secure microservices using OAuth2 and JWT in a Spring Boot application?
- Configure each microservice with its own OAuth2 authorization server.
- JWTs are not suitable for microservices security.
- Use API Gateway as a central OAuth2 authorization server.
- Use username and password for microservices authentication.
To secure microservices using OAuth2 and JWT in a Spring Boot application, you can use an API Gateway as a central OAuth2 authorization server. This allows the API Gateway to authenticate and authorize requests to microservices using JWT tokens. Each microservice doesn't need its own authorization server, as this would be complex and harder to manage. Username and password-based authentication is not a recommended approach for microservices security. JWTs are suitable for securing microservices when used in conjunction with OAuth2 for access control.
