【SaaS-Export项目】项目搭建 Maven父子项目 父工程被子项目继承 子项目与子项目之间的依赖

一.导入数据库

导入已经存在的数据库

二.创建父项目 parent

创建export_parent项目

创建project,但是不要勾选使用模板(create from archetype),因为不要使用web,所以不用勾选,否则会十分麻烦

添加依赖 pom.xml

在新建每个父工程或者子工程之后，都得点击执行clean,还有install,来生成jar

创建.gitignore

创建.gitignore来过滤不要上传到本地仓库的文件

*.iml
*.jar
*.class
.idea/
target/

规划其他工程

设计子模块
1.jar
export_domain
export_dao
export_system_service
2.war
export_web_manager

<packaging>pom</packaging>
export_parent

<packaging>jar</packaging>
export_domain
export_dao
export_system_service

<packaging>war</packaging>
export_web_manager

创建子项目

创建

在父工程export_parent下面创建子项目export_domain,export_system_service,export_dao,export_web_manager
其中export_web_manager要使用到web,要勾选模板以外其他都不要选择模板
而且 每个模块创建完，第一次，要执行clean与install

测试子模块完全继承父项目中的配置

子模块中没有添加依赖,但是它可以继承父项目中添加的依赖

import org.junit.Test;

public class TestModule {
    
    
    @Test
    public  void  test(){
    
    
        System.out.println("测试子模块完全继承父项目的pom.xml");
    }
}

结果

添加子工程与子工程之间的依赖

A子工程依赖B子工程,所以A工程可以使用B工程中的java类
