tomcat 迁移到weblogic 问题

问题1：

Caused by: java.lang.UnsupportedClassVersionError:
com/audaque/datadiscovery/soap/service/impl/JobManagerWSImpl :
unsupported classversion 52.0

原因：

jdk1.8版本不兼容，weblogic 11g 只支持jdk1.6

解决：使用jdk 1.6编译

问题2：

weblogic中使用commons-lang包报java.lang.NoSuchMethodErro

原因：weblogic先加载自带的commons-lang包

解决：

web-inf/weblogic.xml 下

<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

原因：项目xml-apis.jar 与 weblogic 包冲突

解决：maven pom中排除，IDEA使用maven helper 插件查看依赖
