Java Soap客戶端太慢

Question

我有一個Java Soap客戶端，該客戶端將帶有服務和方法的XML請求發送到遠程服務器，但是它通常很慢，不能被專業使用。 有沒有辦法加快處理速度，還是有更快的方式處理Soap請求？

謝謝您的回答。 這是我的Soap客戶的摘錄。

private SOAPMessage makeMessage(String nodeName, String xmlStr, boolean asResponse) throws Exception {
MessageFactory msgFactory = MessageFactory.newInstance();
SOAPMessage message = msgFactory.createMessage();
SOAPPart part = message.getSOAPPart();
SOAPEnvelope envelope = part.getEnvelope();

envelope.addNamespaceDeclaration("xsi", "http://www.w3.org/1999/XMLSchema-instance");
envelope.addNamespaceDeclaration("xsd", "http://www.w3.org/1999/XMLSchema");

SOAPBody body = envelope.getBody();

SOAPElement element = body.addChildElement(envelope.createName("ns1:" + this.method + (asResponse ? "Response" : "")));
element.addAttribute(envelope.createName("xmlns:ns1"), "urn:" + this.service);
element.addAttribute(envelope.createName("ns1"), "http://schemas.xmlsoap.org/soap/encoding");

SOAPElement ele2 = element.addChildElement(envelope.createName(nodeName));
ele2.addAttribute(envelope.createName("xsi:type"), "xsd:string");
ele2.addTextNode(xmlStr);


if (!asResponse) message.saveChanges();

return message;
}

private boolean sendRequest() throws Exception {
 try {
  SOAPConnectionFactory conFactory = SOAPConnectionFactory.newInstance();
  SOAPConnection con = conFactory.createConnection();
  URL endpoint = new URL(this.getURI());

  SOAPMessage message = this.makeMessage("msgstr", this.request.toString(), false);
  SOAPMessage retval = con.call(message, endpoint);
    //extraction du XML en String lisible du message SOAP
  this.response = extractXML(retval);

} catch (Exception e) {
  this.response = e.getMessage();
}
return true;
}

您應該啟用用於客戶端的框架的所有跟蹤/日志信息，以查看問題出在哪里。

如果您使用的是jax-ws，則一種簡單的方法是：

System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");
