利用CXF框架开发WebService(�?

西瓜 — Tue, 24 Nov 2009 13:20:00 GMT

开发工��P��MyEclipse 6.0

开发环境：

1. jdk1.5

2. CXF框架�Q�版�?span style="font-family: Helvetica; color: black; font-size: 14pt;">apache-cxf-2.2.3.zip�Q�到http://cxf.apache.org/download.html下蝲

注：如��?span style="color: red;">jdk1.6�q�行开发，需下蝲jaxb-api.jar�?span style="color: red;">jaxws-api.jar�Q�然后在本机安装JDK的地方，�?span style="color: red;">jdk1.6.0�?span style="color: red;">jre文�g夹下�?span style="color: red;">lib文�g夹中新徏endorsed文�g夹，攑օ�以上两个jar包才可以�q�行开�?/strong>�?/span>

�W�一步，先在MyEclipse新徏一�?/strong>java��目�Q�项目名�?/strong>HelloWebService�?/span>

�W�二步，在项目中引入apache-cxf-2.2.3.zip�?/strong>lib下的所�?/strong>jar包�?/strong>

�W�三步，�~�写��试用接口以及其实现�c�：

接口�Q?/span>

Java代码

package test;



import javax.jws.WebService;



public interface Hello {



    public String sayHello(String str);



}

package test; import javax.jws.WebService; public interface Hello { public String sayHello(String str); }

实现�c�：

Java代码

package test;



public class HelloImpl implements Hello {



    public String sayHello(String str) {



        System.out.println("调用成功");

        return "Hello " + str;

    }



}

package test; public class HelloImpl implements Hello { public String sayHello(String str) { System.out.println("调用成功"); return "Hello " + str; } }

在接口中��d��WebService的注解，��其标注�?span style="font-size: 14pt;">WebService的服务接口�?/p>

Java代码

@WebService

public interface Hello {

@WebService public interface Hello {

�W�四步，�~�写WebService的服务器端�?/strong>

Java代码

package test;



import org.apache.cxf.endpoint.Server;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;



public class MainServer {



    public static void main(String[] args) {

        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();

        factory.setAddress("http://localhost:8080/HelloWebService");

        factory.setServiceClass(HelloImpl.class);

        Server server = factory.create();

        server.start();

    }

}

package test; import org.apache.cxf.endpoint.Server; import org.apache.cxf.jaxws.JaxWsServerFactoryBean; public class MainServer { public static void main(String[] args) { JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean(); factory.setAddress("http://localhost:8080/HelloWebService"); factory.setServiceClass(HelloImpl.class); Server server = factory.create(); server.start(); } }

factory.setAddress("http://localhost:8080/HelloWebService");

讄��服务在服务器上部�|�的位置

factory.setServiceClass(HelloImpl.class);

讄��服务暴露的接口实现类

完成之后�q�行MainServer中的main�Ҏ��?/p>

注：因�ؓCXF框架中有Jetty 6 服务器，所以这个的demo发布在其中运行�?/p>

之后打开��览器，输入�Q?/p>
http://localhost:8080/HelloWebService?wsdl

如能看见以下画面�?span style="font-size: 14pt;">WebService发布成功�Q?/p>

Xml代码

�W�五步，�~�写客户�?/strong>

Java代码

package test;



import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;



public class Client {

    public static void main(String[] args) {

        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

        factory.setServiceClass(Hello.class);

        factory.setAddress("http://localhost:8080/HelloWebService");

        Hello hello = (Hello)factory.create();



        System.out.println(hello.sayHello("weberyb"));

    }



}

package test; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setServiceClass(Hello.class); factory.setAddress("http://localhost:8080/HelloWebService"); Hello hello = (Hello)factory.create(); System.out.println(hello.sayHello("weberyb")); } }

factory.setServiceClass(Hello.class);

讄��讉K��服务器端的指定接口�?/p>

factory.setAddress("http://localhost:8080/HelloWebService");

讄��讉K��的服务的地址�?/p>

factory.create()

创徏代理对象以供�q�程调用

之后�q�行Client�?span style="font-size: 14pt;">main�Ҏ��Q�可以在控制台的服务器端看见如下输出�Q?/p>

Java代码

....................

2009-8-13 14:00:42 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass

信息: Creating Service {http://test/}HelloService from class test.Hello

Hello weberyb

.................... 2009-8-13 14:00:42 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass 信息: Creating Service {http://test/}HelloService from class test.Hello Hello weberyb

说明客户端调�?span style="font-size: 14pt;">WebService成功�?/p> ��x��Q�这个简单的WebService开发完�?br /> ��试�q�jdk1.6   它的包会变成import org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean; �q�且没有factory.setAddress�q�个�Ҏ�� 采用自带的例子进行测�?会出现参数null错误�Q�但是客��L��调用服务器端都调用成功，可能原因是没有加载那两个JAR文�g的问题，暂时没有��试
