1.0. 使用maven的好处

1.使用maven管理工程。

2.Jar包的管理

3.工程之间的依赖管理

4.自动打包

1.1. 后台工程搭建分析

Maven的常见打包方式：jar、war、pom

Pom工程一般都是父工程，管理jar包的版本、maven插件的版本、统一的依赖管理。聚合工程。

e3-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。

|--e3-common：通用的工具类通用的pojo。打包方式jar

|--e3-manager：服务层工程。聚合工程。Pom工程

|--e3-manager-dao：打包方式jar

|--e3-manager-pojo：打包方式jar

|--e3-manager-interface：打包方式jar

|--e3-manager-service：打包方式：jar

    |--e3-manager-web：表现层工程。打包方式war

1.2. 工程搭建

1.2.1. e3-parent

Pom工程。

开发环境：eclipse mars2

Maven：3.3.9

本地仓库：默认位置在~/.m2/repository

Eclipse不需要配置，只需要把本地仓库放到当前用户目录下的.m2下。

如果不是啊的话需要手动配置路径本地仓库位置 需要settings.xml 

更新本地仓库路径

这是我的本地路径

D:\E3商城\工具\MavenRepository\MavenRepository\.m2\.m2\repository

1.1.1. e3-manager-pojo

是一个maven模块，打包方式jar。

pom.xml

<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">

</project>

聚合工程

.....以此类推 建立 

e3-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。

|--e3-common：通用的工具类通用的pojo。打包方式jar

|--e3-manager：服务层工程。聚合工程。Pom工程

|--e3-manager-dao：打包方式jar

|--e3-manager-pojo：打包方式jar

|--e3-manager-interface：打包方式jar

|--e3-manager-service：打包方式：jar

    |--e3-manager-web：表现层工程。打包方式war

最后启动项目时 需要配置Tomcat

 

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<display-name>e3-manager-web</display-name>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	
	
</web-app>

1.1. 启动工程

启动e3-manager工程。

需要在e3-manager 的pom工程中，配置tomcat插件。启动的端口号，和工程名称。

在e3-manager的pom文件中添加如下配置：

<!-- 配置tomcat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>

启动tomcat插件：

clean tomcat7:run

先把e3-parent、e3-common安装到本地仓库。然后再启动。

启动成功！
