What are the latest development trends of Java frameworks?

The latest Java framework trends include: microservice architecture (increases flexibility), containerization (simplifies deployment), cloud-native development (emphasis on scalability), reactive programming (increases resource utilization) and low-code development ( reduce programming requirements). For example, using the Spring Boot framework you can create a microservice: add Spring Boot Web and Eureka Client dependencies, implement the HelloController class, and set up Eureka as a service discovery tool. Run the application and access the URL, which will display "Hello from Spring Boot!" .

Latest Development Trends in Java Frameworks

Java frameworks are constantly evolving to keep up with the demands of modern software development. Here are some of the latest trends:

Microservice architecture

Microservice architecture decomposes applications into a series of loosely coupled, independently deployable services that can improve Development speed and flexibility. Frameworks such as Spring Cloud and Micronaut provide support for microservices development.

Containerization

Containerization technologies, such as Docker, enable applications to run in isolated environments, simplifying deployment and portability. Container orchestration platforms such as Kubernetes are also becoming popular tools for managing containerized applications.

Cloud native development

The cloud native development method uses cloud services to build and run applications, emphasizing scalability, elasticity and pay-as-you-go features. Frameworks such as Spring Boot, Quarkus, and Helidon provide cloud-native development capabilities.

Reactive Programming

The reactive programming model enables non-blocking programming, allowing applications to handle concurrent requests while maximizing resource utilization. The Reactor Project provides powerful support for reactive programming.

Low-code development

Low-code development platforms allow developers to quickly build applications using visual tools and code generators, reducing the requirements for programming knowledge. Frameworks like Mendix and OutSystems are popular choices for low-code development.

Practical Case: Spring Boot Microservices

To demonstrate these trends, we can create a microservice example using Spring Boot.

Create a Spring Boot project and add the following dependencies in it:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

Create the following controller class:

@RestController
@RequestMapping("/hello")
public class HelloController {

    @GetMapping
    public String hello() {
        return "Hello from Spring Boot!";
    }
}

Finally, use Eureka as the service discovery tool:

application.properties
spring.application.name=demo-service
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

Run the application and access it using the following command:

curl http://localhost:8080/hello

You should see the response "Hello from Spring Boot!", which indicates that the microservice is running normally.
