CXF WebService Dynamic Client

すなわち、実行中にメモリに動的にClient(SEIとData Class)を生成する.CXFにはJaxWsDynamicClientFactoryが用意されています.
Dynamic Client.

1.簡単なDynamic Clientを作成する

import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.endpoint.Client;

import java.lang.reflect.Method;

public class OrderProcessJaxWsDynamicClient {
	public OrderProcessJaxWsDynamicClient() {
	}

	public static void main(String str[]) throws Exception {
		
		JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
		Client client = dcf.createClient("http://localhost:8080/OrderProcess?wsdl");
		Object order = Thread.currentThread().getContextClassLoader().loadClass("org.pcdp.sample.webservice.server.Order").newInstance();
		Method m1 = order.getClass().getMethod("setCustomerID", String.class);
		Method m2 = order.getClass().getMethod("setItemID", String.class);
		Method m3 = order.getClass().getMethod("setQty", Integer.class);
		Method m4 = order.getClass().getMethod("setPrice", Double.class);
		m1.invoke(order, "C001");
		m2.invoke(order, "I001");
		m3.invoke(order, 100);
		m4.invoke(order, 200.00);
		Object[] response = client.invoke("processOrder", order);
		System.out.println("Response is " + response[0]);
	}
}

出力の実行:

 : Created classes: org.pcdp.sample.webservice.server.ObjectFactory, org.pcdp.sample.webservice.server.Order, org.pcdp.sample.webservice.server.ProcessOrder, org.pcdp.sample.webservice.server.ProcessOrderResponse
Response is ORD1234

2. Using the CXF service model for building dynamic client

import java.beans.PropertyDescriptor;
import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.endpoint.Endpoint;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.service.model.BindingInfo;
import org.apache.cxf.service.model.BindingMessageInfo;
import org.apache.cxf.service.model.BindingOperationInfo;
import org.apache.cxf.service.model.MessagePartInfo;
import org.apache.cxf.service.model.ServiceInfo;

public class OrderProcessJaxWsDynClient {
	public OrderProcessJaxWsDynClient() {
	}

	public static void main(String str[]) throws Exception {
		JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
		Client client = dcf.createClient("http://localhost:8080/OrderProcess?wsdl");
		Endpoint endpoint = client.getEndpoint();

		// Make use of CXF service model to introspect the existing WSDL
		ServiceInfo serviceInfo = endpoint.getService().getServiceInfos().get(0);
		QName bindingName = new QName("http://server.webservice.sample.pcdp.org/","OrderProcessServiceSoapBinding");
		BindingInfo binding = serviceInfo.getBinding(bindingName);
		QName opName = new QName("http://server.webservice.sample.pcdp.org/", "processOrder");
		BindingOperationInfo boi = binding.getOperation(opName); // Operation name is processOrder
		
		BindingMessageInfo inputMessageInfo = null;
		if (!boi.isUnwrapped()) {
			// OrderProcess uses document literal wrapped style.
			inputMessageInfo = boi.getWrappedOperation().getInput();
		} else {
			inputMessageInfo = boi.getUnwrappedOperation().getInput();
		}

		List<MessagePartInfo> parts = inputMessageInfo.getMessageParts();
		MessagePartInfo partInfo = parts.get(0); // Input class is Order

		// Get the input class Order
		Class<?> orderClass = partInfo.getTypeClass();
		Object orderObject = orderClass.newInstance();

		// Populate the Order bean
		// Set customer ID, item ID, price and quantity
		PropertyDescriptor custProperty = new PropertyDescriptor("customerID",orderClass);
		custProperty.getWriteMethod().invoke(orderObject, "C001");
		PropertyDescriptor itemProperty = new PropertyDescriptor("itemID",orderClass);
		itemProperty.getWriteMethod().invoke(orderObject, "I001");
		PropertyDescriptor priceProperty = new PropertyDescriptor("price",orderClass);
		priceProperty.getWriteMethod().invoke(orderObject,Double.valueOf(100.00));
		PropertyDescriptor qtyProperty = new PropertyDescriptor("qty",orderClass);
		qtyProperty.getWriteMethod().invoke(orderObject, Integer.valueOf(20));

		// Invoke the processOrder() method and print the result
		// The response class is String
		Object[] result = client.invoke(opName, orderObject);
		System.out.println("The order ID is " + result[0]);
	}
}
