使用XFire+Spring+Struts构建Web Service及测试
<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" 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 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" 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
