java调用webservice的几种方法

package client;

import javax.xml.namespace.QName;

import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;

public class RPCClient {
public static void main(String[] args) throws Exception {
// 使用RPC方式调用WebService
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
// 指定调用WebService的URL
EndpointReference targetEPR = new EndpointReference(
"http://localhost:9090/axis2/services/SimpleService");
options.setTo(targetEPR);
// 指定getGreeting方法的参数值
Object[] opAddEntryArgs = new Object[] { "超人" };
// 指定getGreeting方法返回值的数据类型的Class对象
Class[] classes = new Class[] { String.class };
// 指定要调用的getGreeting方法及WSDL文件的命名空间
QName opAddEntry = new QName("http://ws.apache.org/axis2",
"getGreeting");
// 调用getGreeting方法并输出该方法的返回值
System.out.println(serviceClient.invokeBlocking(opAddEntry,
opAddEntryArgs, classes)[0]);
// 下面是调用getPrice方法的代码，这些代码与调用getGreeting方法的代码类似
classes = new Class[] { int.class };
opAddEntry = new QName("http://ws.apache.org/axis2", "getPrice");
System.out.println(serviceClient.invokeBlocking(opAddEntry,
new Object[] {}, classes)[0]);
}
}


第二种：使用WSDL2Java根据wsdl生成java客户端，直接调用客户端即可
package ws.client;



public class Client
{
    public static void main(String[] args) throws Exception 
    {

    MyServiceLocator service = new MyServiceLocator();
    MyServicePortType stub = service.getmyServiceHttpSoap12Endpoint();
   
    System.out.println(stub.getGreeting("wolao"));
    }
}
