第2步: 创建子工程 - YuHaiQing233/explore-cloud-alibaba GitHub Wiki

1. 创建maven工程

2. 选择SDK

3. 设置子工程名称

4. 配置子工程中的相关依赖

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>explore-cloud-alibaba</artifactId>
        <groupId>com.explore</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloud-user</artifactId>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>

        <!-- web工程依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- Spring Boot 程序监控器 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

    </dependencies>

</project>

5. 创建 application.yaml,并且配置服务名称与端口

server:
  port: 10001

spring:
  application:
    name: cloud-user

6. 创建 启动类 与 控制器类

启动类 UserApplication

package com.explore.user;

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

/**
 * 用户服务 启动类
 *
 * @author: YuHaiQing
 * @time: 2022/2/1 18:40
 */
@SpringBootApplication
public class UserApplication {

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

}

控制器类 UserController

package com.explore.user.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 用户 控制器类
 *
 * @author: YuHaiQing
 * @time: 2022/2/1 18:40
 */
@RestController
@RequestMapping("/api/user")
public class UserController {

    @Value("${server.port}")
    private Integer port;

    @GetMapping("/info")
    public String info(){
        return "服务名称: cloud-user, 端口: " + port;
    }
    
}

7. 启动 用户服务

8. 访问接口

9. 按照创建用户服务的步骤，创建 产品服务 与 订单服务
