weblogic10.3.6 启动项目报 weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS WERE FOUND

<Nov 9, 2017 2:47:56 PM CST> <Error> <J2EE> <BEA-160197>
<Unable to load descriptor /payment/applications/payment-api/WEB-INF/web.xml
of module payment-api. The error is weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS WERE FOUND
problem: cvc-enumeration-valid:
string value '3.0' is not a valid enumeration value for web-app-versionType in namespace http://java.sun.com/xml/ns/javaee:<null>

......
原因：
项目中用到的是javaEE6.0，生成的web.xml中默认是web-app_3_0.xsd的定义，而 weblogic10.3.6并不支持web-app_3_0.xsd的定义，需要weblogic 12c版本才支持

解决办法:
将web.xml中web-app版本改为2.5即可。
如下：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns="http://java.sun.com/xml/ns/javaee"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"    version="2.5">
