用Soap消息调用Web Services（续）

上篇《用Soap消息调用Web Services》只是简单的调用一个返回值为String的无参数WebService，这次改成调用一个参数为int型的返回值为一个类对象的WebService<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

服务器端WebService：

public class userimplementsSerializable
{
privateStringname;
publicuser()
{

}
publicStringgetName(){
returnname;
}
publicvoidsetName(Stringname){
this.name=name;
}

}

public class classDemoimplementsSerializable
{
privateuser[]users;

publicuser[]getUsers(){
returnusers;
}

publicvoidsetUsers(user[]users){
this.users=users;
}
}

public class HelloWorldServiceImplimplementsIHelloWorldService
{

publicclassDemoGetUsersInRoom(intrID)
{
classDemocd=newclassDemo();
user[]a=newuser[2];
a[0]=newuser();
a[0].setName("aa");
a[1]=newuser();
a[1].setName("bb");
cd.setUsers(a);
returncd;
}

}

客户端代码：

public static void doSoapPost()
{
try
{
//Firstcreatetheconnection
SOAPConnectionFactorysoapConnFactory=
SOAPConnectionFactory.newInstance();
SOAPConnectionconnection=
soapConnFactory.createConnection();

//Next,createtheactualmessage
MessageFactorymessageFactory=MessageFactory.newInstance();
SOAPMessagemessage=messageFactory.createMessage();

//Createobjectsforthemessageparts
SOAPPartsoapPart=message.getSOAPPart();
SOAPEnvelopeenvelope=soapPart.getEnvelope();
SOAPBodybody=envelope.getBody();

//PopulatetheMessage
StreamSourcepreppedMsgSrc=newStreamSource(
newFileInputStream("E://soap.msg"));
soapPart.setContent(preppedMsgSrc);
//Savethemessage
message.saveChanges();
//Checktheinput
System.out.println("/nREQUEST:/n");
message.writeTo(System.out);
System.out.println();
//Sendthemessageandgetareply

//Setthedestination
Stringdestination=
"http://localhost:8080/HelloWorld/services/HelloWorldService";
//Sendthemessage
SOAPMessagereply=connection.call(message,destination);

//Checktheoutput
System.out.println("/nRESPONSE:/n");
//Createthetransformer
TransformerFactorytransformerFactory=
TransformerFactory.newInstance();
Transformertransformer=
transformerFactory.newTransformer();
//Extractthecontentofthereply
SourcesourceContent=reply.getSOAPPart().getContent();
//Settheoutputforthetransformation
StreamResultresult=newStreamResult(System.out);

transformer.transform(sourceContent,result);
System.out.println();
//Closetheconnection
connection.close();
}
catch(Exceptione)
{
System.out.println(e.getMessage());
}
}

客户端Soap请求格式：

REQUEST:
<? xmlversion = " 1.0 " encoding = " UTF-8 " ?>
< soap:Envelopexmlns:soap = " http://schemas.xmlsoap.org/soap/envelope/ " xmlns:xsd = " http://www.w3.org/2001/XMLSchema " xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance " >
< soap:Body >
< ns1:GetUsersInRoomxmlns:ns1 = " http://phinecos.cnblogs.com " >
< in0xsi:type = ' xsd:int ' > 3
</ in0 >
</ ns1:GetUsersInRoom >
</ soap:Body >
</ soap:Envelope >

服务器端响应结果：
