WebService CXF 使用例子-优快云博客

本文介绍了一个简单的WebService搭建过程，包括Apache CXF的安装配置、接口定义及实现、服务器端与客户端的创建步骤，并展示了如何通过浏览器验证服务是否正常运行。

学习了一下WebService, 做了个小例子，以供参考:

1. 下载 apache-cxf-2.2.12.zip 包，地址: http://cxf.apache.org/

2. 创建 java 工程，导入相关的jar包.

3. 创建一个接口(使用注解声明webservice @WebService )

package test;

import javax.jws.WebService;

@WebService
public interface HelloWorld {

    public String sayHello(String name);

}

4. 实现创建的接口

package test;

import javax.jws.WebService;

@WebService
public class HelloWorldImpl implements HelloWorld {
	public String sayHello(String name) {
		// TODO Auto-generated method stub
		System.out.println("接口实现类!");
		return "Hello "+name+" ! ";
	}

}

5. 创建WebService服务器端

package test;

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class MainServer {

            /**
               * 创建一个服务端
          */
             public static void main(String[] args) {
                 // 创建一个WebService服务端工厂类
           JaxWsServerFactoryBean factory =new JaxWsServerFactoryBean();
                 //定义webService具体实现类,而不是接口
           factory.setServiceClass(HelloWorldImpl.class);  
	 //发布webServer到这个地址
	factory.setAddress("http://localhost:9001/HelloWorld");
		
	//得到Server,并启动
	Server server= factory.create() ;
	server.start();
            }

}

启动服务器端程序， IE浏览器中 http://localhost:9001/HelloWorld?WSDL

可以看到, 服务器端正常

<?xml version="1.0" encoding="UTF-8" ?>

- <wsdl:input name="sayHello">
  <soap:body use="literal" /> 
  </wsdl:input>
- <wsdl:output name="sayHelloResponse">
  <soap:body use="literal" /> 
  </wsdl:output>
  </wsdl:operation>
  </wsdl:binding>
- <wsdl:service name="HelloWorldImplService">
- <wsdl:port binding="tns:HelloWorldImplServiceSoapBinding" name="HelloWorldImplPort">
  <soap:address location="http://localhost:9001/HelloWorld" /> 
  </wsdl:port>
  </wsdl:service>
  </wsdl:definitions>

6. 创建webService客户端

package test;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class HelloClient {

	/**
	 * 创建WebService客户端
	 */
	public static void main(String[] args) {
		// 创建代理工厂类(客户端)
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();	
		factory.setAddress("http://localhost:9001/HelloWorld");
		//客户端定义实现接口
		factory.setServiceClass(HelloWorld.class);
		
		HelloWorld hello= (HelloWorld)factory.create();
		System.out.println(hello.sayHello("中 国"));
 
	}

}

最后启动服务器端程序MainServer,客户端HelloClient ，会显示

2011-7-24 17:42:00 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://test/}HelloWorldService from class test.HelloWorld
Hello 中 国 !

此时WebService发布成功!
