一、搭建父项目

创建第一个maven项目作为父项目

 

 创建完之后建议删掉src文件夹

pom.xml

 <packaging>POM</packaging>
       <!--依赖版本的锁定-->
      <properties>
           <java.version>1.8</java.version>
           <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
           <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
           <spring-boot.version>2.3.2.RELEASE</spring-boot.version>
           <spring-cloud.version>Hoxton.SR9</spring-cloud.version>
           <spring-cloud-alibaba.version>2.2.6.RELEASE</spring-cloud-alibaba.version>
       </properties>

       <dependencyManagement>
           <dependencies>
               <!-- SpringBoot 依赖配置 -->
               <dependency>
                   <groupId>org.springframework.boot</groupId>
                   <artifactId>spring-boot-dependencies</artifactId>
                   <version>${spring-boot.version}</version>
                   <type>pom</type>
                   <scope>import</scope>
               </dependency>
           </dependencies>

       </dependencyManagement>
    

版本的锁定：注意对应关系https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E

 

 

二、搭建基础子项目

再创建一个子项目作为基础项目

 

 

 

基础项目shop-common 里的 pom.xml

<modelVersion>4.0.0</modelVersion>
       <parent>
             <!-- artifactId里放父项目的项目名-->
            <artifactId>spcloud-shop</artifactId>
            <groupId>com.zsx</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>

    <artifactId>shop-common</artifactId>

    <!--依赖-->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.56</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.44</version>
        </dependency>
    </dependencies>

 父项目的pom.xml

创建子模块

User

package com.zsx.model;//用户

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {

    private Integer uid;//主键
    private String username;//用户名
    private String password;//密码
    private String telephone;//手机号
}

三、创建springboot项目

 

 

 

修改刚创好的项目里的pom.xml文件

 <parent>
        <artifactId>spcould-shop</artifactId>
        <groupId>com.zsx</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>shop-user</artifactId>

    <dependencies>
        <!--springboot-web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--shop-common-->
        <dependency>
            <groupId>com.zsx</groupId>
            <artifactId>shop-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

最关键一步，点击maven，在父工程下install初始化一下，这时父子工程才能关联。关联成功控制台会出现BUILD SUCCESS。

在shop-user里写个controller进行测试

package com.zsx.shopuser.controller;

import com.zsx.model.User;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author zsx
 * @site 15595.....
 * @company 爱情废柴
 * @create 2022-11-24-15:38
 */
@RestController
@RequestMapping("/user")
public class UserController {
    @RequestMapping("/get/{uid}")
    public User get(@PathVariable("uid") Integer uid){
        return new User(uid,"zs","12345","10086");
    }
}

启动ShopUserApplication

package com.zsx.shopuser;

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

@SpringBootApplication
public class ShopUserApplication {

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

}

在打开浏览器输入localhost:8080/user/get/1
