java - JAXB Soap 服务运行时错误(未找到 XPath 方法)

Question

我正在创建一个基于 SOAP 的 Web 服务，使用 JAXB 和 Spring 框架将它们组合在一起。我正在使用 spring 的 Web 服务动态生成 wsdl 文件，但是当我尝试访问它时，出现以下错误:

java.lang.NoSuchMethodError: org.apache.xpath.XPathContext.<init>(Z)V
at org.apache.xpath.jaxp.XPathExpressionImpl.eval(XPathExpressionImpl.java:115)
at org.apache.xpath.jaxp.XPathExpressionImpl.eval(XPathExpressionImpl.java:99)
at org.apache.xpath.jaxp.XPathExpressionImpl.evaluate(XPathExpressionImpl.java:184)
at org.springframework.xml.xpath.Jaxp13XPathExpressionFactory$Jaxp13XPathExpression.evaluate(Jaxp13XPathExpressionFactory.java:114)
at org.springframework.xml.xpath.Jaxp13XPathExpressionFactory$Jaxp13XPathExpression.evaluateAsNodeList(Jaxp13XPathExpressionFactory.java:106)
at org.springframework.ws.transport.http.WsdlDefinitionHandlerAdapter.transformLocations(WsdlDefinitionHandlerAdapter.java:200)
at org.springframework.ws.transport.http.WsdlDefinitionHandlerAdapter.handle(WsdlDefinitionHandlerAdapter.java:128)
at org.springframework.ws.transport.http.MessageDispatcherServlet.doService(MessageDispatcherServlet.java:213)

at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:778)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:734)

现在首先，我以前从未在 NoSuchMethodError 末尾见过 (Z)V，所以我不确定这意味着什么，但我在这里也得到了非常有限的堆栈跟踪。我也不明白同一项目中的类如何调用不存在的方法。如果有人对我应该从哪里开始解决这个问题有一些想法，那就太好了。当然可以根据要求提供更多信息。

编辑:

因此，使用 mvn depedency:tree 命令查看是否存在具有不同 xpath 版本的多个 jar，我得到以下输出:

我没有看到任何可疑的东西，所以我不确定还能去哪里。我正在继续尝试使用 glassfish 的 -verbose 选项来跟踪错误。谢谢大家。

编辑 2:因此在 glassfish 日志中显示以下内容:

[Loaded org.springframework.web.context.request.AbstractRequestAttributes from file:/C:/glassfish/glassfish/domains/domain1/applications/licensingSoap/WEB-INF/lib/spring-web-3.1.0.RELEASE.jar]

[Loaded org.apache.xml.utils.IntStack from file:/C:/glassfish/glassfish/domains/domain1/applications/licensingSoap/WEB-INF/lib/xalan-2.6.0.jar]

这肯定表明 xalan-2.6.0 jar 正在加载，但是当我查看 maven 项目的 target\licensingSoap 文件夹时，只有 xalan-2.7.1 jar，我假设这是我想要的。我不知道这个 jar 是如何在 glassfish 上运行时出现的。有什么想法吗？

Answer 1

您可能会从某个地方获取错误版本的类文件。使用 -verbose:class 重新运行以查看所有这些类是从哪里加载的。如果您需要帮助解释结果，请在此处发布结果(如果可以的话 - 不知道允许的尺寸是多少!)。

HTH，
