首先是Web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class> org.directwebremoting.servlet.DwrServlet </servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>context</servlet-name>
<servlet-class>
org.springframework.web.context.ContextLoaderServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 监听器 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
其次是applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="UserManager" class="com.test.UserManager">
</bean>
</beans>
然后是dwr.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr/dwr20.dtd">
<dwr>
<allow>
<create javascript="liushumiao" creator="spring">
<param name="beanName" value="UserManager" />
</create>
</allow>
</dwr>
//编写的测试方法
package com.test;
public class UserManager {
public boolean getUser(String username)
{
System.out.println(username);
if (username.equals("aaa"))
{
return true;
}
else
{
return false;
}
}
}
接下来就是jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type='text/javascript' src='/Ds/dwr/interface/liushumiao.js'></script>
<script type='text/javascript' src='/Ds/dwr/engine.js'></script>
<script type='text/javascript' src='/Ds/dwr/util.js'></script>
<script type="text/javascript">
function checkUser(){
liushumiao.getUser("aaa",callback);
}
function callback(data){
if(data==true){
alert("我成功了");
}else{
alert("我也成功了")
}
}
</script>
</head>
<body οnlοad="checkUser()">
</body>
</html>
最主要的就是导入应有的jar包
