WSDL2Java generated Client

也就是依据wsdl文件生成java客户端，直接调用。查看调用方式，也就是OrderProcessService的getOrderProcessPort方法，获得服务的引用。

启动服务端

mvn test –Pserver

在启动服务端时，通过maven-compiler-plugin编译class，通过cxf-codegen-plugin依据src/main/resources/OrderProcess.wsdl生成存根类OrderProcessService

启动客户端

mvn test -PStubClient

JAX-WS Proxy

和生成存根类的方式相反，proxy是不需要执行wsdl2java的。但是在编译环境中需要接口类和VO类。这里，通过指定WSDL_LOCATION和PORT_NAME，使用Service.create创建service，使用service.getPort获得服务引用。

Java代码

package demo.order.client;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import demo.order.Order;
import demo.order.OrderProcess;
public class ProxyClient {
private static final QName SERVICE_NAME = new QName("http://order.demo/", "OrderProcessService");
private static final QName PORT_NAME = new QName("http://order.demo/", "OrderProcessPort");
private static final String WSDL_LOCATION = "http://localhost:8080/OrderProcess?wsdl";
public static void main(String args[]) throws Exception {
URL wsdlURL = new URL(WSDL_LOCATION);
Service service = Service.create(wsdlURL, SERVICE_NAME);
OrderProcess port = service.getPort(PORT_NAME, OrderProcess.class);
Order order = new Order();
order.setCustomerID("C001");
order.setItemID("I001");
order.setPrice(100.00);
order.setQty(20);
String result = port.processOrder(order);
System.out.println("The order ID is " + result);
}
}

package demo.order.client;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.ws.Service;import demo.order.Order;import demo.order.OrderProcess;public class ProxyClient {    private static final QName SERVICE_NAME = new QName("http://order.demo/", "OrderProcessService");    private static final QName PORT_NAME = new QName("http://order.demo/", "OrderProcessPort");    private static final String WSDL_LOCATION = "http://localhost:8080/OrderProcess?wsdl";    public static void main(String args[]) throws Exception {        URL wsdlURL = new URL(WSDL_LOCATION);        Service service = Service.create(wsdlURL, SERVICE_NAME);        OrderProcess port = service.getPort(PORT_NAME, OrderProcess.class);  Order order = new Order();order.setCustomerID("C001");order.setItemID("I001");order.setPrice(100.00);order.setQty(20);        String result = port.processOrder(order);        System.out.println("The order ID is " + result);        }    }

启动服务端

mvn test –Pserver

启动客户端

mvn test -PProxyClient

Client Proxy

使用JaxWsProxyFactoryBean 类简化Proxy。

Java代码

package demo.order.client;
import demo.order.Order;
import demo.order.OrderProcess;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class ClientProxyClient {
public static void main(String args[]) throws Exception {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(OrderProcess.class);
factory.setAddress("http://localhost:8080/OrderProcess");
OrderProcess service = (OrderProcess)factory.create();
Order order = new Order();
order.setCustomerID("C001");
order.setItemID("I001");
order.setPrice(100.00);
order.setQty(20);
String result = service.processOrder(order);
System.out.println("The order ID is " + result);
}
}

package demo.order.client;import demo.order.Order;import demo.order.OrderProcess;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;public class ClientProxyClient {    public static void main(String args[]) throws Exception {        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();        factory.setServiceClass(OrderProcess.class);        factory.setAddress("http://localhost:8080/OrderProcess");        OrderProcess service = (OrderProcess)factory.create();Order order = new Order();order.setCustomerID("C001");order.setItemID("I001");order.setPrice(100.00);order.setQty(20);        String result = service.processOrder(order);        System.out.println("The order ID is " + result);        }    }

启动服务端

mvn test –Pserver

启动客户端

mvn test -PClientProxyClient

Dynamic Client

甚至不需要SEI接口类，

Reflection API

JaxWsDynamicClientFactory.newInstance获得JaxWsDynamicClientFactory实例。通过dcf.createClient获得Client客户端引用。

Java代码

package demo.order.client;
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("demo.order.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]);
}
}

package demo.order.client;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("demo.order.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]);}}

启动服务端

mvn test –Pserver

启动客户端

mvn test -POrderProcessJaxWsDynamicClient

Service Model API

最后，Service Model是CXF内置的获取Service的信息。

Java代码

package demo.order.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://order.demo/", "OrderProcessServiceSoapBinding");
BindingInfo binding = serviceInfo.getBinding(bindingName);
QName opName = new QName("http://order.demo/", "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]);
}
}
