本文介绍如何使用DWR实现在Java Web应用中的实时数据交互。首先将DWR.jar添加到项目中，并配置web.xml文件引入DWR Servlet。接着在JSP页面引入必要的JavaScript文件并编写客户端调用服务端方法的示例代码。

首先下载DWR.jar然后拷贝到工程目录中，加入工程然后在web.xml中设置dwrservlet

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet-mapping> <servlet-name>dwrservlet</servlet-name> <url-pattern>/dwr/*</url-pattern> </servlet-mapping> <servlet> <servlet-name>dwrservlet</servlet-name> <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>true</param-value> </init-param> </servlet> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

注意设置init-param参数后才可以查看

http://localhost:8080/web/dwr/index.html

获取可用java类映射

然后在JSP中加入对应代码

<%@page contentType="text/html" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <mce:script type="text/javascript" src="extjs/adapter/ext/ext-base.js" mce_src="extjs/adapter/ext/ext-base.js"></mce:script> <mce:script type="text/javascript" src="extjs/ext-all.js" mce_src="extjs/ext-all.js"></mce:script> <mce:script type='text/javascript' src="/web/dwr/interface/DwrTime.js" mce_src="web/dwr/interface/DwrTime.js"></mce:script> <mce:script type='text/javascript' src="/web/dwr/engine.js" mce_src="web/dwr/engine.js"></mce:script> <mce:script type='text/javascript' src="/web/dwr/util.js" mce_src="web/dwr/util.js"></mce:script> <mce:script language="javascript" type="text/javascript"></mce:script> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>JSP Page</title> </head> <body> username:<input type="text" οnchange="sendreq()" name="username" value="" /> password:<input type="text" name="password" value="" /> </body> </html>

然后启动服务在username中任意输入值后在password处返回时间
