一、serverspringcloud整体父工程Project创建
创建父工程，Packageing是pom模式
主要是定义POM文件，将后续各个子模块公用的jar包等统一提出来，类似一个抽象父类
POM文件：
<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>
<groupId>com.smilexl.springcloud</groupId>
<artifactId>servicespringcloud</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>

<maven.compiler.target>1.8</maven.compiler.target>
<junit.version>4.12</junit.version>
<log4j.version>1.2.17</log4j.version>
<lombok.version>1.16.18</lombok.version>
</properties>

二、serverspringcloud-api公共子模块module
<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>
<!-- 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 -->
<parent>
<groupId>com.smilexl.springcloud</groupId>
<artifactId>microservicecloud</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>microservicecloud-api</artifactId><!-- 当前Module我自己叫什么名字 -->
<!-- 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 -->
<dependencies>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
</dependencies>
新建部门Entity且配合Lombok使用：
package com.smilexl.springcloude.entities;
import java.io.Serializable;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;
@SuppressWarnings("serial") //压制警告
@NoArgsConstructor //无参构造方法
@Data // setter、getter 方法
@Accessors(chain=true) //链式结构
public class Dept implements Serializable{ //必须实现序列化
private Long id; //主键
private String dname;// 部门名称
private String db_source; //来自哪个数据库
}
mvn clean install后给其它模块引用，达到通用目的。即用到部门实体的话，不用每一个工程都定义一份，直接引用模块即可。
