The server does not support version 3.1 of the JEE Web module specification.

The server does not support version 3.1 of the JEE Web module specification.

在服务器Tomcat 7部署时，提示“The server does not support version 3.1 of the JEE Web module specification.”，即服务器不支持3.1版的JEE Web模块规范。

打开项目根目录下.settings的文件夹，该文件夹下有一个org.eclipse.wst.common.project.facet.core.xml文件，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<runtime name="com.genuitec.runtime.generic.jee70"/>
<fixed facet="java"/>
<fixed facet="wst.jsdt.web"/>
<fixed facet="jst.web"/>
<installed facet="java" version="1.7"/>
<installed facet="jst.web" version="3.1"/>
<installed facet="jst.web.jstl" version="1.2.2"/>
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="me.hibernate" version="4.1"/>
</faceted-project>

把

<installed facet="jst.web" version="3.1"/>改成

<installed facet="jst.web" version="3.0"/>这样就可以了
