问题描述
我在我的应用程序中都使用了Spring Web服务和Axis2.它们是完全独立的，并且运行良好，只是Spring WebServiceTemplate开始在下面引发异常.
I use Spring web services and Axis2 both in my app. They are completely independent and it works great, except that Spring WebServiceTemplate started throwing the exception below..
我怀疑是因为Spring需要saaj.jar(具有javax.xml.soap.SOAPElement)，而Axis2需要axiom-dom.jar(具有org.apache.axiom.om.impl.dom.ElementImpl)
I suspect it's happening because Spring requires saaj.jar (which has javax.xml.soap.SOAPElement) and Axis2 requires axiom-dom.jar (which has org.apache.axiom.om.impl.dom.ElementImpl)
这两个接口都扩展了org.w3c.dom.Element并通过某种方式让Spring从axiom-dom.jar中获取了一个
Both the interfaces extend org.w3c.dom.Element and somehow Spring in picking up the one from axiom-dom.jar
除了防止将axiom-dom.jar重命名为z-axiom-dom.jar之外，其他任何有关防止Spring在运行时获取错误实现的想法，
Any ideas as to what i can do to prevent Spring from picking up the wrong implementation at runtime other than perhaps renaming axiom-dom.jar to z-axiom-dom.jar, so its later in the classpath?

推荐答案
这不是saaj和axiom-dom之间的冲突，而是saaj和axis2-saaj.jar之间的冲突. axis2-saaj使用公理-dom，这就是为什么异常引用公理的原因.如果您不使用Axis2提供的JAX-WS实现，则不需要axis2-saaj，因此根据您的用例，删除它可能是一个解决方案.
This is not a conflict between saaj and axiom-dom, but a conflict between saaj and axis2-saaj.jar. axis2-saaj uses axiom-dom which is why the exception refers to Axiom. If you don't use the JAX-WS implementation provided by Axis2, then you don't need axis2-saaj, so depending on your use case, removing it may be a solution.
