XFire入门-优快云博客

本文介绍使用XFire框架实现WebService的全过程，包括定义接口、创建实现类、配置服务及发布WSDL，还提供了两种客户端调用示例。

XFire简单示例：
1.声明一个接口

package com.webservice.rowen;
public interface IHelloService {
    public String Hello(String name);
}

2.接口实现类

package com.webservice.rowen;
public class HelloServiceIml implements IHelloService {
    public String Hello(String name) {
        if (null == name) {
            return "Hello Guest";
        } else {
            return "Hello" + name;
        }
    }
}

3.配置service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
 <service>
  <name>HelloService</name>
  <namespace>http://rowen.webservice.com/HelloService</namespace>
  <serviceClass>com.webservice.rowen.IHelloService</serviceClass>
  <implementationClass>com.webservice.rowen.HelloServiceIml
  </implementationClass>
 </service>
</beans>

4.配置web.xml

<servlet>
    <servlet-name>XFireServlet</servlet-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet
   </servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/servlet/XFireServlet/*</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>

4.发布wsdl
发布到Tomcat:http://localhost:8088/XFire/services/HelloService
5.客户端调用（两种方法）
1）自写

package com.webservice.rowen;

	import java.net.MalformedURLException;

	import org.codehaus.xfire.XFireFactory;
	import org.codehaus.xfire.client.XFireProxyFactory;
	import org.codehaus.xfire.service.Service;
	import org.codehaus.xfire.service.binding.ObjectServiceFactory;

	public class ClientInvoke {
		public static void main(String[] args) {
			Service svcModel = new ObjectServiceFactory()
					.create(IHelloService.class);
			XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
					.newInstance().getXFire());
			String helloServiceURL = "http://localhost:8088/XFire/services/HelloService";
			try {
				IHelloService svcHello = (IHelloService) factory.create(svcModel,
						helloServiceURL);
				System.out.println(svcHello.Hello("Rowen"));
			} catch (MalformedURLException e) {
				e.printStackTrace();
			}
		}
	}

2）通过IDE(MyEclipse)生成
File ->New->Other->Web Service -> Web Service Client -->填好 WSDL(或URL) 和生成类所在的包位置,点Finish 就OK了。。
在生成的****Client文件里的
Add custom client code here//从这里开始写代码
6.最小JAR包问题：
