Comparison of advantages and disadvantages of Java frameworks

The most popular Java frameworks are: Spring, Spring Boot, Hibernate, Jakarta EE and Play Framework. Spring and Spring Boot are moderately easy to use, while Hibernate, Jakarta EE, and Play Framework are relatively easy to use. Spring and Spring Boot are more flexible, while Hibernate, Jakarta EE and Play Framework are very flexible. The moderate performance of Spring and Jakarta EE contrasts with the high performance of Hibernate, Spring Boot and Play Framework. All frameworks have high community support, except Play Framework which has medium community support. In terms of learning curve, Spring is steep, Spring Boot is gentle, Hibernate is medium, Jakarta EE is steep, and Play Framework is medium.

Comparison of advantages and disadvantages of Java framework

Introduction

Java framework for Java development People provides powerful tools to build applications quickly and easily. However, choosing the right framework can be daunting, and each framework has its own unique strengths and weaknesses.

Mainstream Java Frameworks

The following are some of the most popular Java frameworks and their main features:

• Spring : A comprehensive framework that provides application foundation, web services, security and persistence.
• Spring Boot: A lightweight version of the Spring framework for quickly starting Java applications.
• Hibernate: An object-relational mapping (ORM) framework that simplifies interaction with databases.
• Jakarta EE: An enterprise-level Java platform that provides service-oriented architecture and Web services.
• Play Framework: An agile and extensible web framework based on the Model-View-Controller (MVC) architecture.

Practical case

Build a RESTful Web service using Spring Boot

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@RestController
@RequestMapping("/api/greeting")
class GreetingController {

    @GetMapping("/")
    public String helloWorld() {
        return "Hello World!";
    }
}

Use Hibernate to access relational database

package com.example.demo;

import javax.persistence.*;

@Entity
public class Message {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;
    private String content;

    // Getters and setters omitted for brevity
}

// ...

Session session = sessionFactory.openSession();
session.beginTransaction();

Message message = new Message();
message.setContent("This is a message.");
session.save(message);

session.getTransaction().commit();
