使用SAAJ发送向WebService发送soap之后，返回的消息中文出现乱码
是这样的，我参考http://www.ibm.com/developerworks/cn/xml/x-jaxmsoap/中的示例，进行测试，由于示例中的WebService不能用，我自己用myEclipse中的JAX-WS框架创建了一个简单的WebService——myFirstWS，myFirstWS对外提供一个sayHello(String name)方法，这个方法返回name+",this is my first Jaxws!".
当客户端调用时，当传入的name为中文的时候，在服务器端接受到的参数很正常，不出现乱码，但是返回到客户端的消息中就会出现乱码。具体代码如下：
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
public class SOAPTip {
public static void main(String args[]) {
try {
// First create the connection
SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnFactory.createConnection();
//Next, create the actual message
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage message = messageFactory.createMessage();
message.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "gb2312");
SOAPPart soapPart = message.getSOAPPart();
//Create objects for the message parts
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPBody body = envelope.getBody();
//Populate the body
//Create the main element and namespace
SOAPElement bodyElement = body.addChildElement(envelope.createName("sayHello", "ns1", "http://jaxws.shaw.com/"));
//Add content
String city = "北京";
bodyElement.addChildElement("arg0").addTextNode(city);
//Save the message
message.saveChanges();
//Check the input
System.out.println("\\nREQUEST:\\n");
message.writeTo(System.out);
System.out.println();
//Send the message and get a reply
//Set the destination
String destination = "http://localhost:8080/myFirstWS/HelloJaxwsPort?wsdl";
//Send the message
SOAPMessage reply = connection.call(message, destination);
//Check the output
System.out.println("\\nRESPONSE:\\n");
//Create the transformer
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
//Extract the content of the reply
Source sourceContent = reply.getSOAPPart().getContent();
//Set the output for the transformation
StreamResult result = new StreamResult(System.out);
transformer.transform(sourceContent, result);
System.out.println();
// Close the connection
connection.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
上面的程序传入的name为“北京”，运行之后，客户端接收到如下消息：
<?xml version="1.0" encoding="UTF-8" standalone="no"?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:sayHelloResponse xmlns:ns2="http://jaxws.shaw.com/"><return>鍖椾含,this is my first Jaxws!</return></ns2:sayHelloResponse></S:Body></S:Envelope>
请各位帮忙看一下问题出在什么地方？谢谢。
另外，myFirstWS的wsdl和xsd文档如下：

[解决办法]
统一字符集，服务器端和客户端都使用统一的字符集UTF-8
