Have you worked with Java 21 and microservices?

Java 21 is one of the latest versions of Java, which includes new features and performance improvements. In the context of microservices, Java 21 can be used with modern frameworks such as Spring Boot, Micronaut, or Quarkus, which support reactive programming, native compilation, and simplify microservice development.

Experience with Java 21 and microservices typically includes:

• Creating RESTful APIs using Spring Boot or similar frameworks.
• Using containerization (Docker) and orchestration (Kubernetes).
• Implementing patterns such as Circuit Breaker, Service Discovery, API Gateway.
• Monitoring and logging microservices.

Example of a simple microservice using Spring Boot:

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String hello() {
        return "Hello from Java 21 microservice!";
    }
}
