maven 建立一个web-app后. 选择JDK1.7. 不能选择Dynamic Web Module3.0的修改办法.


第一步: 先选择JDK1.7

第二步: 修改pom.xml 添加:

 
        
            org.apache.maven.plugins
            maven-compiler-plugin
            3.0
            
                1.7
                1.7

第三步: 修改/WEB-INF/web.xml 替换整个头文件

	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                             http://xmlns.jcp.org/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
