首先在web.xml中要添加如下部分
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<display-name>DWR Servlet</display-name>
<!--最好指定為org.directwebremoting.servlet.DwrServlet-->
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>config-vnd</param-name>
<!--在這裡指定dwr的設定檔-->
<param-value>/WEB-INF/dwr-demo.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
然後在指定的目錄，這裡是/WEB-INF/下面建立一個名字dwr-demo.xml(名字可以自己取)
這個檔案的格式如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
<allow>
<!--這裡指明使用dwr需要的參數，沒有則可以不寫-->
<convert converter="bean" match="com.yjb.vo.DwrDemoVO"/>
<!--這裡指明使用何種方式產生你在dwr中需要使用的類以及別名-->
<create creator="new" javascript="dwrDemoBD">
<param name="class" value="com.yjb.DwrDemoBD"/>
<!--包含要使用的方法-->
<include method="sayHellow"/>
</create>
<!--我這裡使用spring整合，改成下面-->
<!--
<create creator="spring" javascript="dwrDemoBD">
<param name="beanName" value="dwrDemoBD"/>
<!--包含要使用的方法-->
<include method="sayHellow"/>
</create>
-->
</allow>
</dwr>
java代碼
package com.yjb
public class DwrDeomBD
{
public String sayHellow(String youName)
{
reutrn "Hellow "+youName;
}
}
最後就是一個jsp
<%@ page language="java" pageEcoding="UTF-8" %>
<html>
<head>
<title>dwr樣本</title>
<script type='text/javascript' src='js/util.js'></script>
<script type='text/javascript' src='js/engine.js'></script>
<script type='text/javascript' src='dwr/interface/dwrDemoBD.js'></script>
<script type='text/javascript'>
function dwrDemo()
{
dwrDemoBD.sayHello("user",callBackHello);
}
function callBackHello(data)
{
alert(data);
}
</script>
</head>
<body>
<input type="button" name="button" value="測試Dwr" onclick="dwrDemo()"/>
</body>
</html>
最後當然別忘了把dwr.jar放到lib目錄下哦 呵呵
