这是一个用Java的调用C＃版的WebService接口的例子：
C＃接口：
<span style="font-size: 11px;">
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Services.Description;
[WebService(Namespace = "http://www.tangs.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service () ...{
//如果使用设计的组件，请取消注释以下行
//InitializeComponent();
}
[SoapRpcMethod(Action = "http://www.tangs.com/Add", RequestNamespace = "http://www.tangs.com/T", ResponseNamespace = "http://www.tangs.com/T", Use = SoapBindingUse.Literal)]
[WebMethod]
public int Add(int a, int b)
...{
return a + b;
}
[SoapRpcMethod(Action = "http://www.tangs.com/Hello", RequestNamespace = "http://www.tangs.com/T", ResponseNamespace = "http://www.tangs.com/T", Use = SoapBindingUse.Literal)]
[WebMethod]
public String HelloWorld()
...{
return "Hello, world!";
}
}
...</span>Java的调用这个web服务中的添加方法和HelloWorld的方法：
1，有参方法：添加
<span style="font-size: 11px;">
public static void addTest() {
try ...{
Integer i = 1;
Integer j = 2;
//WebService URL
String service_url = "http://localhost:4079/ws/Service.asmx";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(service_url));
//设置要调用的方法
call.setOperationName(new QName("http://www.tangs.com/T", "Add"));
//该方法需要的参数
call.addParameter("a", org.apache.axis.encoding.XMLType.XSD_INT,
javax.xml.rpc.ParameterMode.IN);
call.addParameter("b", org.apache.axis.encoding.XMLType.XSD_INT,
javax.xml.rpc.ParameterMode.IN);
//方法的返回值类型
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT);
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://www.tangs.com/Add");
//调用该方法
Integer res = (Integer)call.invoke(
new Object[]...{
i, j
}
);
System.out.println( "Result: " + res.toString());
} catch (Exception e) ...{
System.err.println(e);
}
}...
</span>运行，结果返回：结果：3
2.无参方法：的HelloWorld
<span style="font-size: 11px;">
public static void helloTest() {
try ...{
String endpoint = "http://localhost:4079/ws/Service.asmx";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName(new QName("http://www.tangs.com/T", "HelloWorld"));
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://www.tangs.com/Hello");
String res = (String)call.invoke(
new Object[]...{
null
}
);
System.out.println( "Result: " + res);
} catch (Exception e) ...{
System.err.println(e.toString());
}
}...
</span>可以看到，调用无参的web服务和有参的基本相同，不过无参调用时，不需要调用呼叫的addParameter方法和setReturnType方法
执行查询查询结果报道查看：你好，世界！
