构建父工程
- 打开Pycharm,新建工程，选择Maven
创建工程
- 填写GroupID和ArtifactID
groupId ：the unique identifier of the organization or group that created the project
artifactId ：unique base name of the primary artifact being generated by this project
GroupID 是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。
ArtifactID是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。 - 创建项目，完善pom文件
工程目录
在pom文件中增加<packaging>pom</packaging>
构建其它模块
-
分别构建api、common、mapper、pojo、service模块
构建子模块
同样选择Maven，其余步骤与创建父模块相同

- 各个模块依赖关系
pojo->common
mapper->pojo
service->mapper
api->service
注意在各个pom中添加相关依赖
添加项目依赖
在父模块的pom文件中添加项目所需依赖

Install模块
image.png
Install成功在控制台会报build success
试运行
- 在api模块Java目录下com.jc(你自己的groupId)下创建Application文件
package com.imooc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import tk.mybatis.spring.annotation.MapperScan;
@SpringBootApplication
// 扫描 mybatis 通用 mapper 所在的包
//@MapperScan(basePackages = "com.jc.mapper")
// 扫描所有包以及相关组件包
//@ComponentScan(basePackages = {"com.jc", "org.n3r.idworker"})
public class Application {
public static void main(String [] args){
SpringApplication.run(Application.class, args);
}
}
- 在api模块创建controller包，创建IndexController文件
package com.jc.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class IndexController {
@GetMapping("/hello")
public Object hello(){
return "hello world";
}
}
- 在api模块resource文件夹下创建application.yml

运行application.java文件，访问http://localhost:8088/hello，即可看到结果
