因为要用到 JUnit ，所以在依赖中添加 spring-test。 并且将 junit 改为较新的 4.10 。

maven 不能设置为 web3.0 解决方法
错误： Description Resource Path Location Type Cannot change version of project facet Dynamic Web Module to 3.0.
首先在硬盘下找到 \项目名\.setting\文件夹 下的 org.eclipse.wst.common.project.facet.core.xml xml文件。
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="wst.jsdt.web"/>
<installed facet="jst.web" version="2.3"/>
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="java" version="1.7"/>
</faceted-project>
将 jst.web 的version 改成 3.0.
然后在eclipse里右键该工程--maven--updateProject （或按 Alt + F5）即可。
