WebService CXF学习（进阶篇3）：对象传递

前面几节都是讲一些理论知识，现在又用一个例子来说明一下，这一节我们就CXF框架对象传递进行讲解。第一步：创建传输对象Customer

@XmlRootElement(name="Customer") @XmlAccessorType(XmlAccessType.FIELD) @XmlType(propOrder = {"name","age"}) public class Customer { private int age; private String name; public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

@XmlRootElement-指定XML根元素名称（可选） @XmlAccessorType-控制属性或方法序列化四种方案： FIELD-对每个非静态，非瞬变属性JAXB工具自动绑定成XML，除非注明XmlTransient NONE-不做任何处理 PROPERTY-对具有set/get方法的属性进行绑定，除非注明XmlTransient PUBLIC_MEMBER -对有set/get方法的属性或具有共公访问权限的属性进行绑定，除非注明XmlTransient @XmlType-映射一个类或一个枚举类型成一个XML Schema类型第二步：创建WebService接口

@WebService public interface HelloService { public void save(Customer c1,Customer c2); public void test(String args); public Customer get(int id); }

每三步：创建WebService接口实现类

@WebService public class HelloServiceImpl implements HelloService { public void save(Customer c1, Customer c2) { System.out.println(c1.getAge()+"---"+c2.getAge()); System.out.println(c1.getName()+"---"+c2.getName()); } public void test(String args) { System.out.println(args); } public Customer get(int id) { Customer cus = new Customer(); cus.setAge(100); cus.setName("Josen"); return cus; } }

第四步：创建服务端

public class SoapServer { ublic static void main(String[] args){ //两种方法，任选一种发布WebService接口 //Endpoint.publish("http://localhost:8080/helloService", new HelloServiceImpl()); JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean(); factory.setAddress("http://localhost:8080/helloService"); factory.setServiceClass(HelloServiceImpl.class); factory.getInInterceptors().add(new LoggingInInterceptor()); factory.getOutInterceptors().add(new LoggingOutInterceptor()); factory.create(); }

第五步：创建客户端

public class SoapClient { public static void main(String[] args){ JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setAddress("http://localhost:8080/helloService"); factory.setServiceClass(HelloService.class); factory.setServiceClass(HelloServiceImpl.class); factory.getInInterceptors().add(new LoggingInInterceptor()); HelloService service = (HelloService)factory.create(); Customer c1 = new Customer(); c1.setAge(1); c1.setName("aaa"); Customer c2 = new Customer(); c2.setAge(2); c2.setName("bbb"); service.save(c1, c2); service.test("aaaaaaaaaaaaa"); } }

最后，测试程序运行服务端程序，在浏览器地址栏输入http://localhost:8080/helloService?wsdl查看接口是否发布成功。成功则运行一下客户端程序，看看对象传输是否成功。现在我们来分析一下控制打印的日志信息。

当客户端向服器发送请求时，服务端LoggingInInterceptor拉截客户端发送过来的SOAP消息，如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <ns1:sayHi xmlns:ns1="http://client.itdcl.com/"> <text>Josen</text> </ns1:sayHi> </soap:Body> </soap:Envelope>

客户端将请求信息封闭在<soap:Body></soap:Body>中，当然也可以将其放到<soap:Header></soap:Header>，只要在@WebParam中的header设置成true,默认为false; 服务器接到请求之后，响应客户端。同样以SOAP形式将信息封装好发回客户端，SOAP信息如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <text xmlns="http://client.itdcl.com/">hi Josen</text> </soap:Header> <soap:Body> <ns1:sayResponse xmlns:ns1="http://client.itdcl.com/"></ns1:sayResponse> </soap:Body> </soap:Envelope>

正文到此结束
