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

1. package demo.order.client; 
2.  
3. import java.net.URL; 
4. import javax.xml.namespace.QName; 
5. import javax.xml.ws.Service; 
6.  
7. import demo.order.Order; 
8. import demo.order.OrderProcess; 
9.  
10. public class ProxyClient { 
11.  
12.     private static final QName SERVICE_NAME = new QName("http://order.demo/", "OrderProcessService"); 
13.     private static final QName PORT_NAME = new QName("http://order.demo/", "OrderProcessPort"); 
14.  
15.     private static final String WSDL_LOCATION = "http://localhost:8080/OrderProcess?wsdl"; 
16.  
17.     public static void main(String args[]) throws Exception { 
18.         URL wsdlURL = new URL(WSDL_LOCATION); 
19.         Service service = Service.create(wsdlURL, SERVICE_NAME); 
20.         OrderProcess port = service.getPort(PORT_NAME, OrderProcess.class);   
21.  
22.         Order order = new Order(); 
23.         order.setCustomerID("C001"); 
24.         order.setItemID("I001"); 
25.         order.setPrice(100.00); 
26.         order.setQty(20); 
27.  
28.         String result = port.processOrder(order); 
29.         System.out.println("The order ID is " + result); 
30.          
31.     } 
32.      
33. } 

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

1. package demo.order.client; 
2.  
3.  
4. import demo.order.Order; 
5. import demo.order.OrderProcess; 
6. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; 
7.  
8. public class ClientProxyClient { 
9.  
10.     public static void main(String args[]) throws Exception { 
11.         JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); 
12.         factory.setServiceClass(OrderProcess.class); 
13.         factory.setAddress("http://localhost:8080/OrderProcess"); 
14.         OrderProcess service = (OrderProcess)factory.create(); 
15.  
16.         Order order = new Order(); 
17.         order.setCustomerID("C001"); 
18.         order.setItemID("I001"); 
19.         order.setPrice(100.00); 
20.         order.setQty(20); 
21.  
22.         String result = service.processOrder(order); 
23.         System.out.println("The order ID is " + result); 
24.          
25.     } 
26.      
27. } 

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

1. package demo.order.client; 
2.  
3. import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory; 
4. import org.apache.cxf.endpoint.Client; 
5.  
6. import java.lang.reflect.Method; 
7.  
8. public class OrderProcessJaxWsDynamicClient { 
9.     public OrderProcessJaxWsDynamicClient() { 
10.     } 
11.  
12.     public static void main(String str[]) throws Exception { 
13.         JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); 
14.         Client client = dcf.createClient("http://localhost:8080/OrderProcess?wsdl"); 
15.                  
16.         Object order = Thread.currentThread().getContextClassLoader().loadClass("demo.order.Order").newInstance(); 
17.         Method m1 = order.getClass().getMethod("setCustomerID", String.class); 
18.         Method m2 = order.getClass().getMethod("setItemID", String.class); 
19.         Method m3 = order.getClass().getMethod("setQty", Integer.class); 
20.         Method m4 = order.getClass().getMethod("setPrice", Double.class); 
21.         m1.invoke(order, "C001"); 
22.         m2.invoke(order, "I001"); 
23.         m3.invoke(order, 100); 
24.         m4.invoke(order, 200.00); 
25.                  
26.         Object[] response = client.invoke("processOrder", order); 
27.         System.out.println("Response is " + response[0]); 
28.  
29.     } 
30. } 

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

1. package demo.order.client;

25.         Client client = dcf.createClient("http://localhost:8080/OrderProcess?wsdl"); 
26.         Endpoint endpoint = client.getEndpoint(); 
27.  
28.  
29.         // Make use of CXF service model to introspect the existing WSDL 
30.         ServiceInfo serviceInfo = endpoint.getService().getServiceInfos().get(0); 
31.         QName bindingName = new QName("http://order.demo/", "OrderProcessServiceSoapBinding"); 
32.         BindingInfo binding = serviceInfo.getBinding(bindingName); 
33.         QName opName = new QName("http://order.demo/", "processOrder"); 
34.         BindingOperationInfo boi = binding.getOperation(opName); // Operation name is processOrder 
35.         BindingMessageInfo inputMessageInfo = null; 
36.         if (!boi.isUnwrapped()) { 
37.             //OrderProcess uses document literal wrapped style. 
38.             inputMessageInfo = boi.getWrappedOperation().getInput(); 
39.         } else { 
40.             inputMessageInfo = boi.getUnwrappedOperation().getInput(); 
41.         } 
42.  
43.         List<MessagePartInfo> parts = inputMessageInfo.getMessageParts(); 
44.         MessagePartInfo partInfo = parts.get(0); // Input class is Order 
45.  
46.         // Get the input class Order 
47.         Class<?> orderClass = partInfo.getTypeClass(); 
48.         Object orderObject = orderClass.newInstance(); 
49.  
50.         // Populate the Order bean 
51.         // Set customer ID, item ID, price and quantity 
52.         PropertyDescriptor custProperty = new PropertyDescriptor("customerID", orderClass); 
53.         custProperty.getWriteMethod().invoke(orderObject, "C001"); 
54.         PropertyDescriptor itemProperty = new PropertyDescriptor("itemID", orderClass); 
55.         itemProperty.getWriteMethod().invoke(orderObject, "I001"); 
56.         PropertyDescriptor priceProperty = new PropertyDescriptor("price", orderClass); 
57.         priceProperty.getWriteMethod().invoke(orderObject, Double.valueOf(100.00)); 
58.         PropertyDescriptor qtyProperty = new PropertyDescriptor("qty", orderClass); 
59.         qtyProperty.getWriteMethod().invoke(orderObject, Integer.valueOf(20)); 
60.  
61.         // Invoke the processOrder() method and print the result 
62.         // The response class is String 
63.         Object[] result = client.invoke(opName, orderObject); 
64.         System.out.println("The order ID is " + result[0]); 
65.     } 
66. }
