请看上一章架构讲解：
整体父工程Project
  1.新建父工程microservicecloud，切记Packaging是pom模式
主要是定义POM文件，将后续各个子模块公用的jar包等统一起来microservicecloud（root）根目录的pom：

<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">

子工程，注意是在父工程里面建立module
microservicecloud-api的pom

<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">
    <modelVersion>4.0.0</modelVersion>

    <parent><!-- 子类里面显示声明才能有明确的继承表现，无意外就是父类的默认版本否则自己定义 -->
        <groupId>com.atguigu.springcloud</groupId>
        <artifactId>microservicecloud</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>microservicecloud-api</artifactId><!-- 当前Module我自己叫什么名字 -->

    <dependencies><!-- 当前Module需要用到的jar包，按自己需求添加，如果父类已经包含了，可以不用写版本号 -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>

 目录结构

entities Dept

@Data
@AllArgsConstructor
@NoArgsConstructor
@Accessors(chain = true)   //链式结构注解
public class Dept implements Serializable {
    private Long deptno; // 主键
    private String dname; // 部门名称
    private String db_source; //来自哪个数据库,因为微服务架构可以一个服务对应一个数据库
}

 

 导入成功后Install
