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!
