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:definitions name="HelloWorldImplService" targetNamespace="http://test/" xmlns:ns1="http://schemas.xmlsoap.org/wsdl/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://test/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

- <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!
