A recent have a look at the Spring Framework

@RestController
public class MovieController {

    personal ultimate MovieRepository movieRepository;

    public MovieController(MovieRepository movieRepository) {
        this.movieRepository = movieRepository;
    }

    // Discover the return kind
    @GetMapping("/films")
    public Flux<Film> getAllMovies() {
        return movieRepository.findAll();
    }
}

When utility necessities name for high-throughput knowledge processing, WebFlux is a perfect resolution.

Java persistence with Spring Knowledge

Spring Knowledge is a extremely refined, persistence-aware framework that has been refined through the years. Along with supporting Java’s Jakarta Persistence API, Spring gives straightforward entry to newer approaches akin to the next repository class. Be aware that this class doesn’t require any annotation as a result of Spring Boot acknowledges it subclasses a persistence base-class:

import org.springframework.knowledge.repository.reactive.ReactiveCrudRepository;

public interface MovieRepository extends ReactiveCrudRepository<Film, String> {
    
	// You outline the strategy signature; Spring Knowledge R2DBC gives the implementation
	Flux<Film> findByGenre(String style);
}

This code makes use of Spring R2DBC, a relational database connection library that makes use of asynchronous reactive drivers. The wonder is that the engine itself gives the implementation primarily based on the fields and strategies of the info object; because the developer, you should not have to implement the findByGenre methodology.
