java: axis2 Web Service四种调用模式

package userguide.clients;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;

public class ClientUtil {

    public static OMElement getEchoOMElement() {
        OMFactory fac = OMAbstractFactory.getOMFactory();
        OMNamespace omNs = fac.createOMNamespace(
                "http://example1.org/example1", "example1");
        OMElement method = fac.createOMElement("echo", omNs);
        OMElement value = fac.createOMElement("Text", omNs);
        value.addChild(fac.createOMText(value, "Axis2 Echo String "));
        method.addChild(value);

        return method;
    }

    public static OMElement getPingOMElement() {
        OMFactory fac = OMAbstractFactory.getOMFactory();
        OMNamespace omNs = fac.createOMNamespace(
                "http://example1.org/example1", "example1");
        OMElement method = fac.createOMElement("ping", omNs);
        OMElement value = fac.createOMElement("Text", omNs);
        value.addChild(fac.createOMText(value, "Axis2 Ping String "));
        method.addChild(value);

        return method;
    }

}

发送请求返回响应并且阻塞的客户端

 try {
OMElement payload = ClientUtil.getPingOMElement();
Options options = new Options();
options.setTo(targetEPR);
ServiceClient serviceClient = new ServiceClient();
serviceClient.setOptions(options);
serviceClient.fireAndForget(payload);
 
Thread.sleep(500);
} catch (AxisFault axisFault) {
axisFault.printStackTrace();
}

发送请求返回响应,非阻塞,使用一条连接传输

package userguide.clients;

import org.apache.axiom.om.OMElement;
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.client.async.AsyncResult;
import org.apache.axis2.client.async.Callback;

public class EchoNonBlockingClient {
    private static EndpointReference targetEPR = new EndpointReference("http://127.0.0.1:8080/axis2/services/MyService");

    public static void main(String[] args) {
        ServiceClient sender = null;
        try {
            OMElement payload = ClientUtil.getEchoOMElement();
            Options options = new Options();
            options.setTo(targetEPR);
            options.setAction("urn:echo");

            //Callback to handle the response
            Callback callback = new Callback() {
                public void onComplete(AsyncResult result) {
                    System.out.println(result.getResponseEnvelope());
                }

                public void onError(Exception e) {
                    e.printStackTrace();
                }
            };

            //Non-Blocking Invocation
            sender = new ServiceClient();
            sender.setOptions(options);
            sender.sendReceiveNonBlocking(payload, callback);

            //Wait till the callback receives the response.
            while (!callback.isComplete()) {
                Thread.sleep(1000);
            }

        } catch (AxisFault axisFault) {
            axisFault.printStackTrace();
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            try {
                sender.cleanup();
            } catch (AxisFault axisFault) {
                //
            }
        }

    }
