java-springboot

Cuando se use este skill, genera los archivos de un microservicio Spring Boot 3.2.0 con Java 17 y Maven, siguiendo la estructura de paquete com.example.msrandomnumber.

[Setup] — Estructura inicial y configuración del proyecto

Genera los siguientes archivos:

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
         https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.2.0</version>
    <relativePath/>
  </parent>

  <groupId>com.example</groupId>
  <artifactId>ms-random-number</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>ms-random-number</name>
  <description>Microservicio que retorna un número aleatorio del 1 al 9</description>

  </build>
</project>

src/main/java/com/example/msrandomnumber/MsRandomNumberApplication.java

package com.example.msrandomnumber;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MsRandomNumberApplication {

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

[Service] — Capa de servicio

Genera los siguientes archivos:

src/main/java/com/example/msrandomnumber/service/RandomNumberService.java

package com.example.msrandomnumber.service;

public interface RandomNumberService {

    int getRandomNumber();
}

src/main/java/com/example/msrandomnumber/service/RandomNumberServiceImpl.java

package com.example.msrandomnumber.service;

import org.springframework.stereotype.Service;
import java.util.concurrent.ThreadLocalRandom;

@Service
public class RandomNumberServiceImpl implements RandomNumberService {

    @Override
    public int getRandomNumber() {
        return ThreadLocalRandom.current().nextInt(1, 10);
    }
}

[Controller] — Controlador REST

Genera el siguiente archivo:

src/main/java/com/example/msrandomnumber/controller/RandomNumberController.java

package com.example.msrandomnumber.controller;

import com.example.msrandomnumber.service.RandomNumberService;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

@RestController
@RequestMapping("/api")
public class RandomNumberController {

    private final RandomNumberService randomNumberService;

    public RandomNumberController(RandomNumberService randomNumberService) {
        this.randomNumberService = randomNumberService;
    }

    @GetMapping("/random")
    public ResponseEntity<Map<String, Integer>> getRandom() {
        int number = randomNumberService.getRandomNumber();
        return ResponseEntity.ok(Map.of("number", number));
    }
}
