Axis、Axis2、CXF调用WebService的几种方式

第一种：
Axis调用webService：

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.SOAPHeaderElement;
（注意这里引用的包不是axis2是axis）

public static String ask(String url,String method,Object[] params){
String result = null;
try {
            Service service = new Service();

            Call call = (Call) service.createCall();
            call.setTargetEndpointAddress(new java.net.URL(url));
        
            call.setProperty(Call.CONNECTION_TIMEOUT_PROPERTY, new Integer(
60 * 60000));
call.setTimeout(new Integer(60 * 60000));
            call.setOperationName(method);//WSDL里面描述的接口名称

            result = (String)call.invoke(params);

} catch (Exception e) {
log.error("调用webservice接口异常");
e.printStackTrace();
}
return result;
}


第二种：
axis2调用webService
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.rpc.client.RPCServiceClient;

（注意这里引用的是axis2的包）

    public void testRPC(){
        try{
            RPCServiceClient client = new RPCServiceClient();
            Options options = client.getOptions();
//            String url = "http://localhost:8080/axis2/services/HelloWebService?wsdl";
            String url = "http://localhost:8089/webserviceServer/TestService?wsdl";
            EndpointReference end = new EndpointReference(url);
            options.setTo(end);
            Object[] obj = new Object[]{"tom"};
             Class<?>[] classes = new Class[] { String.class }; 
            QName qname = new QName("http://testClick", "sayHello");
            String result = (String) client.invokeBlocking(qname, obj,classes)[0];
            System.out.println(result);
        }catch(AxisFault e){
            e.printStackTrace();
        }
    }

第三种：

import javax.xml.namespace.QName;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.rpc.client.RPCServiceClient;
（引入的包同第二种一样）
    public void testOMElement(){
        try{
            ServiceClient sc = new ServiceClient();
            Options opts = new Options();
            String url = "http://localhost:8080/axis2/services/HelloWebService?wsdl";
            EndpointReference end = new EndpointReference(url);
            opts.setTo(end);
            opts.setAction("sayHello");
            sc.setOptions(opts);
            
            OMFactory fac = OMAbstractFactory.getOMFactory(); 
            OMNamespace omNs = fac.createOMNamespace("http://testClick", ""); 
            OMElement method = fac.createOMElement("sayHello",omNs); 
            OMElement value = fac.createOMElement("name",omNs);
            value.setText("admin");
            method.addChild(value);
            OMElement res = sc.sendReceive(method);
            res.getFirstElement().getText(); 
            System.out.println(res.getFirstElement().getText());
        }catch(AxisFault e){
            e.printStackTrace();
        }
    }


CXF调用webService:
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
String cvsUrl = "http://xxxxxx?wsdl";
Client client = dcf.createClient(cvsUrl);
String params = "{\"username\":\""+config.getDataAcc()+"\",\"password\":\""+config.getDataPwd()+"\",\"jobName\":\""+holeTask.getTaskName()+"\"}";
objects = client.invoke("generalAssetResult", params);
