WebService服务的实现及调用

eclipse下新建webapp项目

此WebService服务由Axis实现,样例项目所需要jar包及目录：

Web.xml配置

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

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
  <display-name>Apache-Axis</display-name>
    
  <!--实际servlet程序，这里是AxisServlet-->
  <servlet>
    <servlet-name>AxisServlet</servlet-name>
    <display-name>Apache-Axis Servlet</display-name>
    <servlet-class>
        org.apache.axis.transport.http.AxisServlet
    </servlet-class>
  </servlet>
 
  <!-- 定义servlet和url的对应关系-->
  <servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>


</web-app>

WebService服务:

package com.archie.service;

/**
 * 服务MyService
 * @author archie
 *
 * since 2011-7-13 下午02:34:57
 */
public class SayHelloService {

    /**
     * 输出List集中字符串
     * @return
     */
    public String SayHello2WS(String name){
        return "Hello,WebService!"+"_____by"+"\t"+name;
    }
}

WebService服务的配置(server-config.xml)

server-config.xml(WEB-INF目录下)

该服务的调用:

package com.archie.service.test;

import javax.xml.namespace.QName;
import javax.xml.rpc.Call;
import javax.xml.rpc.ParameterMode;

import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;

/**
 * WebService接口测试
 * @author archie
 *
 * since 2011-7-13 下午02:06:37
 */
public class TestSayHello {

    public static void main(String[] args) throws Exception {
        //创建一个服务对象
        Service service = new Service();
        //创建一个对方法的调用
        Call call = service.createCall();
        /**
         * 设置调用的终端地址
         * AnotherMethod为server-config.wsdd的Service配置名称
         */
        String url = "http://localhost:8080/MyWebService/services/SayHelloService";
        call.setTargetEndpointAddress(
                url);
        call.setReturnType(XMLType.XSD_STRING);
        //设置操作名，即所调用的方法的名称
        call.setOperationName(new QName("SayHello2WS"));
        //添加参数（参数名，参数类型，参数传递模式）
        call.addParameter("name", XMLType.XSD_STRING, ParameterMode.IN);
        //调用方法
        String res = (String) call.invoke(new Object[]{"archie"});
        
        System.out.println("调用返回结果:"+res);
        
    }
}

运行结果：
