How do Spring Boot microservices communicate with each other?
Spring Boot microservices typically communicate using REST APIs or messaging queues. REST APIs allow synchronous communication, while messaging queues like RabbitMQ or Kafka enable asynchronous communication.
What are the advantages of using messaging queues?
Messaging queues provide decoupling between services, improve scalability, and enhance fault tolerance. They allow services to communicate without being directly connected.
Can you explain how to implement REST communication?
To implement REST communication, you can use Spring Web to create REST controllers. Define endpoints using @GetMapping, @PostMapping, etc., and use RestTemplate or WebClient for client-side calls.
What about security in microservices communication?
For security, you can use OAuth2 for authentication and JWT for secure token-based communication between microservices.
