方式一:
配置CXF环境变量,用wsdl2java工具自动产生代码。项目结构目录如下:
其中com.yq.webservice下面的所有的java类都是wsdl2java工具自动产生的。
JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
factoryBean.getInInterceptors().add(new LoggingInInterceptor());
factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
factoryBean.setServiceClass(HelloWorldDao.class);
factoryBean.setAddress(":8080/WebServiceTest/webservice/helloworld?wsdl");
HelloWorldDao impl = (HelloWorldDao) factoryBean.create();
impl.sayHello("zhengmo");
其中:
http//:8080/WebServiceTest/webservice/helloworld?wsdl是服务端提供的web service的端口地址。
上面的代码就是WebServiceClient.java中main方法里面的代码。
方式二:
任然需要先用wsdl2java工具生成相应的java代码。
HelloWorldDaoService factory = new HelloWorldDaoService();
HelloWorldDao helloWorldDao = factory.getHelloWorldDaoPort();
helloWorldDao.sayHello("zhengmo");
方式三:
最后一种方式不需要使用wsdl2java工具在客户端产生代码。
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
String wsUrl = "http//:8080/WebServiceTest/webservice/helloworld?wsdl";
Client client = dcf.createClient(wsUrl);
String method = "sayHello";//webservice的方法名
Object[] result = null;
try {
result = client.invoke(method, "zhengmo");//调用webservice
} catch (Exception e) {
e.printStackTrace();
}
CXF提供了很多client端的调用方法。这里让你快速了解这些选择,帮助你判断使用哪种。
参见:
http://cxf.apache.org/docs/how-do-i-develop-a-client.html
源代码主体使用PacktPub.Apache.CXF.Web.Service.Development.Dec.2009书中的代码。本例中,将5种调用方式集中在一个工程中,并使用Maven重组的调用方式。

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);
-
- }
-
- }
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);
-
- }
-
- }
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]);
-
- }
- }
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 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]);
- }
- }
//这种方法动态获取服务端对象也可以(亲测成功,jar版本cxf3.0.3)
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://localhost:8080/cxfservice/services/getZdxmlist?wsdl");
Object[] result = client.invoke("getZdxmlist", "在建","2016","zd_ctx");
System.out.println("Echo response: " + result[0]);
JSONArray ja=JSONArray.fromObject(result[0]);
Object objs[]=ja.toArray();
for (int i = 0; i < objs.length; i++) {
System.out.println(JSONObject.fromObject(objs[i]).get("mc"));//输出各个对象的名称属性
}
有可能汇报这个错误:
CXF 异常 Caused by: org.apache.cxf.binding.soap.SoapFault: Unexpected wrapper element
解决 方法:将客户端中的Service的包名改成与服务端中的一致,问题解决。
