通过 Apache CXF 2.x 为肥皂客户端生成代码时出现 NoSuchMethodError

Question

当我通过 Apache CXF 2.x WSDL2Java 为 SOAP 客户端生成所需的类时，我得到了这个异常。任何帮助深表感谢。谢谢！

线程“主”java.lang.NoSuchMethodError 中的异常：com.sun.xml.bind.v2.util.XmlFactory.allowExternalAccess(Ljavax/xml/validation/SchemaFactory;Ljava/lang/String;Z)Ljavax/xml /验证/架构工厂； 在 com.sun.tools.xjc.reader.internalizer.DOMForest.weakSchemaCorrectnessCheck(DOMForest.java:478) 在 com.sun.tools.xjc.api.impl.s2j.SchemaCompilerImpl.bind(SchemaCompilerImpl.java:260) 在 com.sun.tools.xjc.api.impl.s2j.SchemaCompilerImpl.bind(SchemaCompilerImpl.java:95) 在 org.apache.cxf.tools.wsdlto.databinding.jaxb.JAXBDataBinding.initialize(JAXBDataBinding.java:460) 在 org.apache.cxf.tools.wsdlto.WSDLToJavaContainer.generateTypes(WSDLToJavaContainer.java:727) 在 org.apache.cxf.tools.wsdlto.WSDLToJavaContainer.processWsdl(WSDLToJavaContainer.java:271) 在 org.apache.cxf.tools.wsdlto.WSDLToJavaContainer.execute(WSDLToJavaContainer.java:165) 在 org.apache.cxf.tools.wsdlto.WSDLToJavaContainer.execute(WSDLToJavaContainer.java:416) 在 org.apache.cxf.tools.common.toolspec.ToolRunner.runTool(ToolRunner.java:103) 在 org.apache.cxf.tools.wsdlto.WSDLToJava.run(WSDLToJava.java:113) 在 org.apache.cxf.tools.wsdlto.WSDLToJava.run(WSDLToJava.java:86) 在 org.apache.cxf.tools.wsdlto.WSDLToJava.main(WSDLToJava.java:184)

Answer 1

您在 pom.xml 中使用的是较旧的 jaxb-impl 依赖项。

所有 jaxb-impl 版本都列出了here

Answer 2

[用cmets求解]

JDK 随 java6 的 JAXB 一起提供。确保类路径中没有旧版本的 jaxb。如果您使用 CXF 2.7，请包含 2.7.x CXF 发行版中的 stax2-api 和 Woodstox-core-asl jar
