使用XFire+Spring+Struts构建Web Service及测试

  FROM: http://shade8109.blog.163.com/blog/static/130110604200911294257292/?fromdm&fromSearch&isFromSearchEngine=yes

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

 

<?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>YMCN-XFireService</display-name>
<!-- begin Spring配置 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml,/WEB-INF/xfire-servlet.xml</param-value>
</context-param>

 

 

<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.ymcn.filter.CharacterEncoding</filter-class>
</filter>

<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>

 

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:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
</beans>

 

5.xfire-servlet.xml 的内容:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 引入XFire预配置信息 -->
<import resource="classpath:org/codehaus/xfire/spring/xfire.xml"/>

<!-- 使用XFire导出器 -->
<bean id="baseWebService" class="org.codehaus.xfire.spring.remoting.XFireExporter" lazy-init="false" abstract="true">
   <!-- 引用xfire.xml中定义的工厂 -->
   <property name="serviceFactory" ref="xfire.serviceFactory"/>
   <!-- 引用xfire.xml中的xfire实例 -->
   <property name="xfire" ref="xfire"/>
</bean>

<!-- 定义所有访问 WEB服务的url -->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
   <property name="urlMap">
    <map>
        <entry key="/HelloWorldService.ws">

            <ref local="HelloWorldService"/>

        </entry>
    </map>
   </property>
</bean>

<!-- HelloWorld WEB服务 -->
<bean id="HelloWorld" class="org.ymcn.ws.impl.HelloWorldImpl"/>

<bean id="HelloWorldService" parent="baseWebService">
   <!-- 业务服务bean -->
   <property name="serviceBean" ref="HelloWorld"/>
   <!-- 业务服务bean的窄接口类 -->
   <property name="serviceClass" value="org.ymcn.ws.HelloWorld"/>
  </bean>

</beans>

 

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:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<bean id="HelloWorldService" class="org.codehaus.xfire.spring.remoting.XFireClientFactoryBean">
   <property name="serviceClass"><value>org.ymcn.ws.HelloWorld</value></property>
   <property name="wsdlDocumentUrl"><value>http://localhost:8888/wss/HelloWorldService.ws?wsdl</value></property>
</bean>

</beans>

 

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" %>
<html>
<head>
<title>测试WebService - HelloWorld</title>
</head>

<body>

<logic:present name="NAME" scope="request">
<font color="red"><bean:write name="NAME" scope="request"/></font>
</logic:present>

<br>
<form action="/wss/ws/HelloWorld.ymcn" method="post">
用户名：<input type="text" name="name" style="width:500px">
<br><br>
<input type="submit" name="Submit" value=" 提交 "/>
</form>

</body>
</html>

 

8，struts-config.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards />

<action-mappings>
<action path="/ws/HelloWorld" type="org.ymcn.struts.action.WSHelloWorldAction" scope="request" validate="false">
      <forward name="hello-ok" path="/ws/helloWorld.jsp"/>
    </action>
</action-mappings>

<message-resources parameter="org.ymcn.struts.i18n.i18n" />
</struts-config>

 

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

 

 

点击提交:

 

 

 

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
