maven环境变量的安装以及myeclipse上搭建maven支持的SSM：Spring+SpringMVC+Mybatis项目

1.官网下载链接

http://maven.apache.org/download.cgi

下载：apache-maven-3.5.4-bin.tar.gz

2.配置环境变量

新建系统变量：MAVEN_HOME

变量值：maven的路径，例如：D:\apache-maven-3.5.4\apache-maven-3.5.4

添加到path中

%MAVEN_HOME%\bin

3.验证maven安装成功

 windows+R ， cmd进入命令提示符窗口，输入 mvn -v 出现maven的版本信息说明安装成功

4.更改maven本地仓库的位置（maven的仓库概念自行百度）

在maven安装目录下找到conf，将其中setting.xml的<localRepository>/path/to/local/repo</localRepository>

改为

<localRepository>此处填自己建的路径</localRepository>

主要要把此放在注释<!-- -->之外

5.在myeclipse中配置maven

打开myeclipse，window->preferences->搜索maven找到installations->add->更改为本地的maven。

更改setting.xml:在installations同级中找到user settings，将user settings，和global settings改为4步骤中自己建的本地仓库的位置。点击update settings，再点击apply，再点击OK完成配置。

下面就开始搭建maven项目

1.打开myeclipse，file->project->maven project->next两次->选择maven-archetype-quickstart->在弹出的位置填写包名等等(如下图)->finish等待

2.搭建父项目时打包方式选择pom，在创建好父项目后，打开pom.xml,点击create就可创建子项目

3.如果要创建java项目则在1步骤中选择maven-archetype-quickstart，

如果要创建web项目则在1步骤中选择maven-archetype-webapp.

4.如果搭建的是web工程，则在刚创建完后index.jsp会报错，在<dependencies>中加入以下依赖的包就行，

<dependency>

<groupId>javax</groupId>

<artifactId>javaee-api</artifactId>

<version>7.0</version>

</dependency>

并且此web项目的src/main/java和src/test/java源码包是隐藏的，此时按以下步骤添加jre就行：

项目右键->buildPath configure Build Path->点击选项卡Libraries->选中JRE System Library->

点击edit->选中Alternate JRE->选择jdk

点击finish，点击ok，自动出现src/main/java和src/test/java

5.在创建子项目是如果是java项目打包类型就是jar，如果是web项目就是war。

maven项目搭建好了，下面导入SSM项目所需要的依赖，即用到的jar包

在pom.xml中添加依赖：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
