maven学习笔记

1.安装和配置

　　去maven官网下载，这里用的是3.1的版本。然后解压。我这里是D:JavaIDEapache-maven-3.1.0

　　然后是配置环境变量：新增环境变量 MAVEN_HOME:D:JavaIDEapache-maven-3.1.0

　　然后在path的变量中添加;%MAVEN_HOME%in;

2.设置eclipse的maven

3.配置好后，新建maven项目

4.新建web项目时无法出现src/main/java文件夹的解决方法:

在项目上右键选择properties，然后点击java build path，在Librarys下，编辑JRE System Library，选择workspace default jre就可以了。

 5.附上spring4整合hibernate4的pom。

注：有些能通过maven的依赖管理自动下载的jar包就没有写了，反正它自己也会引入的，而且还避免了版本冲突。

　　用的是开源中国的maven库，下载速度那是杠杠滴，配置方法：http://maven.oschina.net/help.html
