在JAX-WS消息中删除XML声明
我正在尝试使用Java代码调用Web服务。 所以我使用JAX-WS和JAXB从wsdl文件生成我的对象。
当我调用webservice时，它会响应此错误：
Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: The [javax.xml.transform.TransformerException] occurred during XSLT transformation: javax.xml.transform.TransformerException: org.xml.sax.SAXParseException: The XML declaration must end with "?>". Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: The [javax.xml.transform.TransformerException] occurred during XSLT transformation: javax.xml.transform.TransformerException: org.xml.sax.SAXParseException: The XML declaration must end with "?>". at com.sun.xml.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:189) at com.sun.xml.ws.fault.SOAPFaultBuilder.createException(SOAPFaultBuilder.java:122) at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:119) at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:89) at com.sun.xml.ws.client.sei.SEIStub.invoke(SEIStub.java:118) 因此，通过wireshark，我分析了正在发送的xml消息。 并试图用soapUI重新发送它。
并发现我的xml包含xml声明
当我从SoapUI中删除它并重新发送它。 消息没问题。
我的java代码是这样的：
public static Data receiveSIBS(webserviceclient.Data input) { webserviceclient.Starter service = new webserviceclient.Starter(); webserviceclient.PortType port = service.getSOAPEventSource(); BindingProvider bp = (BindingProvider) port; bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpoint); return port.receiveSIBS(input); }
如果没有这个xml声明，如何在Java中生成我的消息？ 因为xml消息全部是使用JAX-WS和JAXB生成的。
提前致谢！
找到我自己的解决方案
首先，正如其他post中所提到的，我实现了一个SOAPHandler来编辑这两个属性：
soapMsg.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-16"); soapMsg.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "false");
但是虽然这两个属性会在handleMessage（）方法中更改消息实例，但它不会像它一样发送，并且会发送带有默认xml声明的消息。
而不是设置此属性，解决方案是设置这两个NamespaceDeclaration：
SOAPEnvelope env = sp.getEnvelope(); env.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema"); env.addNamespaceDeclaration("xsi", "http://www.w3.org/2001/XMLSchema-instance");
我不明白为什么我们得到“XML声明必须结束”？>“”错误。 因为我的解决方案没有删除xml声明。 可能与xml结构有关（但我没有足够的知识来确认它）。
我需要参考http://blog.jdevelop.eu/?p=67post，让我参考这个解决方案，一些调试代码来自这篇文章。
接下来，我将完整的CustomHandler类放入其中，以便它可以容纳任何人。
