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

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

############################################################

#

    username: root
    password: root
    hikari:
      connection-timeout: 30000 # 等待连接池分配连接的最大时长（毫秒），超过这个时长还没可用的连接则发生SQ
      minimum-idle: 5 # 最小连接数
      maximum-pool-size: 20 # 最大连接数
      auto-commit: true # 自动提交
      idle-timeout: 600000 # 连接超时的最大时长（毫秒），超时则被释放（retired），默认:10分钟
      pool-name: DateSourceHikariCP # 连接池名字
      max-lifetime: 1800000 # 连接的生命时长（毫秒），超时而且没被使用则被释放（retired），默认:30分钟
      connection-test-query: SELECT 1

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