我在java中創建了一個Soap客戶端，並且出現了一個奇怪的錯誤。SOAPExceptionImpl錯誤響應：404Not未找到，如果我不做soapMessage.writeTo（System.out）;
摘要客戶
public abstract class AbstractSoapClient {
private ServerContext context;
private String path;
private static final String WSSE = "";
private static final String CURL = "";
private static final String CURL_PASSWORD = "";
private static final String SECURITY_NODE = "";
private static final String USERNAME_TOKEN = "";
private static final String USERNAME_NODE = "";
private static final String PASSWORD_NODE = "";
public AbstractSoapClient(ServerContext context) {
this.context = context;
}
protected SOAPMessage createRequest(String path) throws SOAPException {
this.path = assembleEndpoint(path);
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), this.path);
soapConnection.close();
return soapResponse;
}
protected void setCredentials(SOAPEnvelope envelope) throws SOAPException {
SOAPHeader tHeader = envelope.getHeader();
Name tWsseHeaderName = envelope.createName(SECURITY_NODE, WSSE, CURL);
SOAPHeaderElement tSecurityElement = tHeader.addHeaderElement(tWsseHeaderName);
tSecurityElement.setMustUnderstand(false);
Name tUserTokenElementName = envelope.createName(USERNAME_TOKEN, WSSE, CURL);
SOAPElement tUserTokenElement = tSecurityElement.addChildElement(tUserTokenElementName);
tUserTokenElement.removeNamespaceDeclaration(WSSE);
tUserTokenElement.addNamespaceDeclaration("wsu", CURL);
// user name child
Name tUsernameElementName = envelope.createName(USERNAME_NODE, WSSE, CURL);
SOAPElement tUsernameElement = tUserTokenElement.addChildElement(tUsernameElementName);
tUsernameElement.removeNamespaceDeclaration(WSSE);
tUsernameElement.addTextNode(context.getUsername());
// password child
Name tPasswordElementName = envelope.createName(PASSWORD_NODE, WSSE, CURL);
SOAPElement tPasswordElement = tUserTokenElement.addChildElement(tPasswordElementName);
tPasswordElement.removeNamespaceDeclaration(WSSE);
tPasswordElement.setAttribute("Type", CURL_PASSWORD);
tPasswordElement.addTextNode(context.getPassword());
}
private String assembleEndpoint(String path) {
return context.getUrl().concat(path);
}
protected abstract SOAPMessage createSOAPRequest() throws SOAPException;
public ServerContext getContext() {
return context;
}
public String getPath() {
return path;
}
}
SOAP客戶端執行
public class SoapClient extends AbstractSoapClient {
public SoapClient(ServerContext context) {
super(context);
}
@Override
public SOAPMessage createSOAPRequest() throws SOAPException {
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
setCredentials(envelope);
buildBody(envelope);
soapMessage.saveChanges();
try {
soapMessage.writeTo(System.out);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return soapMessage;
}
private void buildBody(SOAPEnvelope envelope) throws SOAPException {
envelope.addNamespaceDeclaration("sch", "------");
SOAPBody soapBody = envelope.getBody();
SOAPElement soapBodyElem = soapBody.addChildElement("sampleData", "sampleData");
SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("sampleData");
soapBodyElem1.addTextNode("sampleData");
SOAPElement soapBodyElem2 = soapBodyElem.addChildElement("sampleData");
soapBodyElem2.addTextNode("sampleData");
SOAPElement soapBodyElem3 = soapBodyElem.addChildElement("sampleData");
soapBodyElem3.addTextNode("Y");
SOAPElement soapBodyElem4 = soapBodyElem.addChildElement("sampleData");
soapBodyElem4.addTextNode("sampleData");
SOAPElement soapBodyElem5 = soapBodyElem.addChildElement("sampleData");
soapBodyElem5.addTextNode("sampleData");
SOAPElement soapBodyElem6 = soapBodyElem.addChildElement("sampleData");
soapBodyElem6.addTextNode("sampleData");
}
public static void main(String[] args) throws SOAPException, IOException {
SoapClient client = new SoapClient(
new ServerContext("url", "user", "password"));
SOAPMessage response = client.createRequest("endpoint");
response.writeTo(System.out);
}
}
奇怪的一點是在這部分代碼：
try {
soapMessage.writeTo(System.out);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
如果我COMM耳鼻喉科這個代碼，只打印請求之前發送它，我得到一個異常：

，但如果我不評論這條線，我可以得到正確的響應，對我來說這是沒有意義的，因爲爲什麼它發送一個404未找到如果我在發送它之前沒有在控制檯中寫入請求。
但是，爲什麼一個的writeTo方法，只有打印流中的請求頭添加到消息，真的是一個很好的做法？ –
我知道這聽起來很奇怪，而且肯定不是一個好習慣，但MessageImpl.writeTo源代碼可以做到這一點。 – fernandospr
