通过Apache CXF 2.x为soap客户端生成代码时出现NoSuchMethodError

Question

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

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

Answer 1

您在pom.xml中使用较旧的jaxb-impl依赖。

此处列出了所有jaxb-impl版本

Answer 2

[在评论中解决]

JDK附带来自java6的JAXB。 确保在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
