一、技术选型

1.1. maven坐标说明

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

1.2. 环境准备

jdk	jdk1.8.0_202
maven	3.6.1
服务器	tomcat7插件
开发工具	IntelliJ IDEA 2019.1

二、工程所属关系

2.1. 项目结构总览

ly-parent :父工程，打包方式pom，管理jar包的版本号,项目中所有工程都应该继承父工程|______ly-common 				 :通用的工具类和枚举类|______ly-manager  			 :服务层工程,聚合工程,Pom工程|______ly-entity		 :实体类|______ly-dao			 :接口|______ly-interface		 :服务接口|______ly-service 		 :逻辑处理层|______ly-web      	     :表现层工程，打包方式war

2.2. 工程所属关系总览

工程名	说明	打包方式	项目所属关系
ly-parent	统一的依赖管理	pom	聚合工程
ly-manager	统一的依赖管理	pom	聚合工程
ly-common	枚举和工具类	jar	子工程
ly-entity	实体类	jar	子工程
ly-dao	mapper接口	jar	子工程
ly-interface	服务接口	jar	子工程
ly-service	逻辑处理层	jar	子工程
ly-web	表现层工程	war	子工程

三、创建聚合工程

3.1. 聚合工程_ly-parent

3.2. 聚合工程_ly-manager

• 在ly-parent项目，右击【new】-【modular】
  

四、创建子项目

• 这4个子项目打包方式都是jar，创建方式一样

项目名称	打包方式
ly-common	jar
ly-entity	jar
ly-dao	jar
ly-interface	jar
ly-service	jar

4.1 创建子工程服务ly-common

• 在ly-parent项目，右击【new】-【modular】
  

4.2 创建子工程服务ly-entity

• 在ly-manager项目，右击【new】-【modular】
  

4.3 创建子工程服务ly-dao

• 在ly-manager项目，右击【new】-【modular】
  

4.4 创建子工程服务ly-interface

• 在ly-manager项目，右击【new】-【modular】
  

4.5 创建子工程服务ly-service

• 在ly-manager项目，右击【new】-【modular】
  

4.6 创建子工程服务ly-web

• 在ly-manager项目，右击【new】-【modular】
• 这个子项目打包方式都是war

项目名称	打包方式
ly-web	war

• 工程总览：

六、启动工程

6.1. 配置tomcat插件

• 需要在ly-manager 的pom工程中，配置tomcat插件。启动的端口号，和工程名称

<!-- 配置tomcat7插件 --><build><plugins><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><configuration><port>8080</port><path>/</path></configuration></plugin></plugins></build>

6.2. 查看tomcat7插件

6.3. 重新编译/安装

• 执行以下命令即可

#重新编译并将jar安装到本地仓库，在此过程中跳过测试
mvn clean install -Dmaven.test.skip=true

• 效果图：
  
  

6.4. 双击tomcat7:run

6.5. 浏览器验证

http://localhost:8080/

到此，所需依赖已经整合完成，工程搭建完成！！！
