利用MyEclipse快速创建webService服务

创建web项目

添加webservice支持，使用xfire

 添加支持以后，MyEclipse自动配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 <!-- start 添加webservice支持以后，Myeclipse自动配置XFire -->
  <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>/services/*</url-pattern>
  </servlet-mapping>
  <!-- end 添加webservice支持以后，Myeclipse自动配置XFire -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 创建接口

package com.hx.webservice;

public interface IWebServiceTest {
	public String getStr();
}

 创建实现类

package com.hx.webservice.imp;

import com.hx.webservice.IWebServiceTest;

public class WebServiceTest implements IWebServiceTest{

	public String getStr() {
		// TODO Auto-generated method stub
		return "webservice  调用成功！";
	}

}

配置service文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>  
        <!-- webserviceq名称，调用时需要指定这个 -->  
        <name>testService</name>  
        <!-- 自己服务的地址 -->  
        <namespace>http://localhost:8080/WebService</namespace>  
        <!-- 接口类 -->  
        <serviceClass>com.hx.webservice.IWebServiceTest</serviceClass>  
        <!-- 实现类 -->  
        <implementationClass>com.hx.webservice.imp.WebServiceTest</implementationClass>  
    </service>  
</beans>

 启动Tomcat，地址栏输入：http://localhost:8080/WebService/services/testService?wsdl

 部署成功。

创建client端，访问webservice服务：

package com.hx.client;

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;

import com.hx.webservice.IWebServiceTest;


public class Client {
	public static void main(String agrs[]){
		//这里是创建一个service，需要传入一个接口类，因为我们后面必须调用相应的接口方法
		Service srcModel = new ObjectServiceFactory().create(IWebServiceTest.class);
		//代理工厂，这里是为了后面创建相应的接口类
		XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire());
		//webservice地址，不需要加wsdl
		String testServiceUrl = "http://localhost:8080/WebService/services/testService";
		
		//利用工厂返回相应的接口类
		IWebServiceTest iTest = null;
		try {
			iTest = (IWebServiceTest)factory.create(srcModel,testServiceUrl);
			String str = iTest.getStr();
			System.out.println(str);
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

 出现错误:

 添加包commons-httpclient-3.0.jar，继续运行：

 成功，几分钟搞定。说到底任何技术都是方便我们使用。更多的精力还是要花在业务上面。
