IDEA创建父子项目

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>POMpackaging>
       
      <properties>
           <java.version>1.8java.version>
           <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
           <project.reporting.outputEncoding>UTF-8project.reporting.outputEncoding>
           <spring-boot.version>2.3.2.RELEASEspring-boot.version>
           <spring-cloud.version>Hoxton.SR9spring-cloud.version>
           <spring-cloud-alibaba.version>2.2.6.RELEASEspring-cloud-alibaba.version>
       properties>
 
       <dependencyManagement>
           <dependencies>
               
               <dependency>
                   <groupId>org.springframework.bootgroupId>
                   <artifactId>spring-boot-dependenciesartifactId>
                   <version>${spring-boot.version}version>
                   <type>pomtype>
                   <scope>importscope>
               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>4.0.0modelVersion>
       <parent>
             
            <artifactId>spcloud-shopartifactId>
            <groupId>com.zsxgroupId>
            <version>1.0-SNAPSHOTversion>
        parent>
 
    <artifactId>shop-commonartifactId>
 
    
    <dependencies>
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-data-jpaartifactId>
        dependency>
        <dependency>
            <groupId>org.projectlombokgroupId>
            <artifactId>lombokartifactId>
        dependency>
        <dependency>
            <groupId>com.alibabagroupId>
            <artifactId>fastjsonartifactId>
            <version>1.2.56version>
        dependency>
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>5.1.44version>
        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-shopartifactId>
        <groupId>com.zsxgroupId>
        <version>1.0-SNAPSHOTversion>
    parent>
    <modelVersion>4.0.0modelVersion>
 
    <artifactId>shop-userartifactId>
 
    <dependencies>
        
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>
        
        <dependency>
            <groupId>com.zsxgroupId>
            <artifactId>shop-commonartifactId>
            <version>1.0-SNAPSHOTversion>
        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
