java无法从给定源创建信封，因为根元素未命名为envelope
我在SoapUI中测试了一个SOAP请求。我成功地得到了想要的回应
当我在下面if (isSuccessResponse(soapResponse)) {测试响应是否成功时，代码中出现了问题：
public static void main(String[] args) throws Exception {
// Establish SOAP connection
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
// Generate SOAP request
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), namespaceURI);
// Test to see if SOAP response is available
System.out.print("SOAP Response:");
System.out.println();
soapResponse.writeTo(System.out);
// Close connection
soapConnection.close();
if (isSuccessResponse(soapResponse)) {
System.out.println("Success!");
} else {
System.out.println("Fault!");
}
}
成功
private static boolean isSuccessResponse(SOAPMessage soapResponse) throws Exception {
NodeList responseNodes = soapResponse.getSOAPBody().getElementsByTagNameNS("*", "HelpDesk_QueryList_Service");
if (responseNodes.getLength() == 1)
return true;
else
return false;
}
请求： 这段代码实际上打印出了正确的请求，因为它与SoapUI中的工作请求相同。那么，为什么我不能从实际回复中获得相关信息呢？打印响应是空白缺省响应，具有所有必需的标题，但没有来自我的请求的期望信息：
private static SOAPMessage createSOAPRequest() throws Exception {
MessageFactory messageFactory = MessageFactory.newInstance();
// Create SOAP Message
SOAPMessage soapMessage = messageFactory.createMessage();
// Add request envelope, headers, and nodes from SOAP request
SOAPPart soapPart = soapMessage.getSOAPPart();
// I used ? here for privacy reasons
String xmlns = "?";
String username = "?";
String password = "?";
String qualification = "'?";
SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration("urn", xmlns);
SOAPHeader soapHeader = envelope.getHeader();
SOAPElement authInfoElem = soapHeader.addChildElement("AuthenticationInfo", "urn");
createElementAndSetText(authInfoElem, "userName", username);
createElementAndSetText(authInfoElem, "password", password);
SOAPBody soapBody = envelope.getBody();
SOAPElement bodyElem = soapBody.addChildElement("HelpDesk_QueryList_Service", "urn");
createElementAndSetText(bodyElem, "Qualification", qualification);
MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("SOAPAction", xmlns + "/HelpDesk_QueryList_Service");
// Save request
soapMessage.saveChanges();
// Print the request message
System.out.print("SOAP Request:");
System.out.println();
soapMessage.writeTo(System.out);
System.out.println();
System.out.println();
return soapMessage;
}
错误：我得到以下错误，但我不确定原因

首先，您的错误似乎发生在SAAJ框架处理响应时。因此，我不会深入研究请求的创建，我认为这很好，特别是因为您提出的情况与SoapUI伪造的请求相同。您还可以检查HTTP头以确保这一点
堆栈跟踪的重要部分是：
这告诉我们SOAP框架无法处理响应信封。假设回答确实有效，这看起来很可疑
看看你的代码，我怀疑这是对SAAJ API的滥用：
在实际使用该消息之前，请先关闭连接。如果SAAJ实现是懒惰的（我想是的，这是有道理的），那么消息不会立即从网络套接字解析。通过在使用响应消息之前关闭连接，实际上是在读取套接字之前关闭了它，因此实现无法读取消息
我建议在使用响应对象后延迟关闭与的连接
代码的这一部分也可以提出同样的论点：
通过将响应转储到控制台，实际上是让框架使用套接字（读取HTTP响应）。稍后，当您要求框架将响应流解析为信封时，如果它没有缓存流的内容，那么该操作将失败：没有更多的字节需要解析
因此，简而言之：在框架有机会真正解析结果之前，不要“触摸”连接或repsonse对象。从API设计的角度来看，这并不明显，但这是一种可以理解的行为
其他一些线索： stackoverflow上的其他人报告说，他们的旧版本的Xerces/Xalan是罪魁祸首（这些是XML解析器，JDK内置了自己版本的Xerces），所以您可能也想检查一下： Java Spring WS org.springframework.ws.soap.saaj.SaajSoapEnvelopeException: Could not access envelope http://mmmsoftware.blogspot.fr/2009/06/xml-namespace-error-with-spring-ws.html
