javaWebserviceClient：使用纯文本xml而不是对象层次结构

我正在用Java编写一个简单的代理：

>读取XML文件
>将请求发送到Web服务
>阅读Web服务响应
>将响应写入文件

我的第一次尝试是使用JAXB读取xml文件并生成Java对象.
然后,我使用JAX-WS(IBM WebSphere)发送对象.
我收到的响应是“ ResponseObject”,然后将其生成为xml代码.我将XML代码写入文件.

此设置效果很好.但…

将Java对象发送到WebService时,将生成xml,并且响应还会创建Java对象.我真的不需要那些请求和响应对象.
有没有一种方法可以使用纯文本xml直接调用WebService？并以纯文本xml而不是那些响应对象的形式读取响应？

(假设xml文件始终有效.)

谢谢

解决方法:

可以使用SAAJ(带有Java附件API的SOAP)运行,其运行级别低于JAX-WS.我希望它比JAX-WS使用更少的系统资源.

请参见以下示例(从users.skynet.be/pascalbotte/rcx-ws-doc/saajpost.htm复制)

No more dynamic construction of the SOAP message this time, let’s use a simple text editor and type the soap message we want to send.

Example 1-13. The formated SOAP message in a text file: prepared.msg

SOAP-ENV:encoding
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:enc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">


your message or e-mail





Now the code will be shorter and you can easily use it for testing purpose.

Example 1-14. Post a SOAP message in a text file, to a web service using SAAJ

import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
import java.io.FileInputStream;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamResult;
public class Client {
public static void main(String[] args) {
try {
// Create the connection
SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
SOAPConnection cOnn= scf.createConnection();
// Create message
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage msg = mf.createMessage();
// Object for message parts
SOAPPart sp = msg.getSOAPPart();
StreamSource prepMsg = new StreamSource(
new FileInputStream("path/prepared.msg"));
sp.setContent(prepMsg);
// Save message
msg.saveChanges();
// View input
System.out.println("\n Soap request:\n");
msg.writeTo(System.out);
System.out.println();
// Send
String urlval = "http://www.pascalbotte.be/rcx-ws/rcx";
SOAPMessage rp = conn.call(msg, urlval);
// View the output
System.out.println("\nXML response\n");
// Create transformer
TransformerFactory tff = TransformerFactory.newInstance();
Transformer tf = tff.newTransformer();
// Get reply content
Source sc = rp.getSOAPPart().getContent();
// Set output transformation
StreamResult result = new StreamResult(System.out);
tf.transform(sc, result);
System.out.println();
// Close connection
conn.close();
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
