1. 开发环境:
        JDK 1.5,   Tomcat 5.5.25,   MyEclipse 6.0 其实也没什么特别之处.

2. 建立工程, 配好环境:
        在MyEclipse下建立Web Project,取名为:wss, (意为:Webservice, Spring, Struts)

        对wss增加:Web Service Capabilities, 记得选择XFire的Core Libraries

        对wss增加:Struts Capabilities

 

3.修改web.xml,使之响应不同的请求以及XFire与Spring的结合

 

http://java.sun.com/dtd/web-app_2_3.dtd">

YMCN-XFireService


    contextConfigLocation
    /WEB-INF/applicationContext.xml,/WEB-INF/xfire-servlet.xml

 

 

    encodingFilter
    org.ymcn.filter.CharacterEncoding

    encodingFilter
   

 

4.在/WEB-INF/下编写applicationContext.xml 和 xfire-servlet.xml两文件,此二文件是必须的,前一个是Spring的,后一个是XFire的,其为被XFire自动加载.

applicationContext.xml 的内容:

http://www.springframework.org/dtd/spring-beans.dtd">

 

5.xfire-servlet.xml 的内容:

http://www.springframework.org/dtd/spring-beans.dtd">

  
  
  
  

  
   

           

       
   
  

  
  
  
  
 

 

此时,我们就已经构建出了一个Web Service,我们在IE中输入:http://localhost:8888/wss/HelloWorldService.ws?wsdl

就能看到WSDL.

 

6.通过Java application 测试:编写JAVA简单测试类:

首先,在wss/src下建个客户端调用Web Service的Spring配置文件:client.xml,内容为:

http://www.springframework.org/dtd/spring-beans.dtd">

   org.ymcn.ws.HelloWorld
   http://localhost:8888/wss/HelloWorldService.ws?wsdl

 

到此我们可以通过client.xml获得HelloWorld

 

package org.ymcn.test.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.ymcn.ws.HelloWorld;

 

public class HelloWorld2 {
    HelloWorld helloWorld = null;
  
    public static void main(String[] args) {
       HelloWorld2 test = new HelloWorld2();
       test.testClient();
    }

    public void testClient() {
       ApplicationContext ctx = new ClassPathXmlApplicationContext("client.xml");
       helloWorld = (HelloWorld)ctx.getBean("HelloWorldService");
     
       System.out.println(helloWorld.sayHello("老牛啊"));
    }
}

运行此程序,如输出:你好啊,老牛啊 说明正确.

 

7.在表示层(Struts)通过JSP调用Web Service:

JSP文件:

 

 

<%@ page language="java" pageEncoding="utf-8"%>
<%@ taglib prefix="html" uri="html" %>
<%@ taglib prefix="bean" uri="bean" %>
<%@ taglib prefix="logic" uri="logic" %>

用户名：

 

8，struts-config.xml文件:

http://struts.apache.org/dtds/struts-config_1_2.dtd">

     
   

 

9.JSP请求Action类:WSHelloWorld

package org.ymcn.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.ymcn.ws.HelloWorld;

public class WSHelloWorldAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response) throws Exception {
 
   String name = (String)request.getParameter("name");
 
   ApplicationContext ctx = new ClassPathXmlApplicationContext("client.xml");
     HelloWorld helloWorld = (HelloWorld)ctx.getBean("HelloWorldService");
     String result = helloWorld.sayHello(name);
   
 
     if(result == null) {
     result = "对不起, 调用WEB服务失败, 请重试......";
     }
   
     request.setAttribute("NAME", result);
   
   return mapping.findForward("hello-ok");
}
}

 

到些,所有的工作已完成,部署WEB工程,启动Tomcat

 

10.在IE中输入:http://localhost:8888/wss/ws/helloWorld.jsp

恭喜你,你的工作得到了回报~~~~~~~~~~~~~~~~~~~~~~~~~~

最后是过滤器类了,我用的全是UTF-8,内容如下:

 

package org.ymcn.filter;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class CharacterEncoding implements Filter
{
    protected String encoding;
    protected FilterConfig filterConfig;

    public void init(FilterConfig filterConfig) throws ServletException
    {
        this.filterConfig = filterConfig;
        this.encoding = "utf-8";
    }

    public void destroy( )
    {
        this.encoding = null;
        this.filterConfig = null;
    }

    public void doFilter(ServletRequest request, ServletResponse response,
       FilterChain chain) throws IOException, ServletException
    {
    request.setCharacterEncoding(encoding);
        chain.doFilter(request, response);
    }

    protected String selectEncoding(ServletRequest request)
    {
        return (this.encoding);
    }
}

好的,所有工作做完了
