DWR集成与Spring结合-优快云博客

1.首先将jar包烤入到lib目录下

2，修改web.xml文件，添加dwr servlet配置

3.在web-inf下面添加dwr.xml配置文件

eg:

首先配置web.xml：

<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>

配置dwr.xml：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd"> <dwr> <allow> <create javascript="SayHello" creator="new" scope="page"> <param name="class" value="com.gengyang.dwr.SayHello" /> </create> </allow> </dwr>

java代码：

package com.gengyang.dwr; public class SayHello { public String sayHelloTo(String name){ return "Hello:"+name; } }

jsp页面注意导入的js文件：

window.onload = function(){

function callback(str){

$("output").innerHTML = str; }

SayHello.sayHelloTo("gengyang",callback); }

</script>

<body>

如果类是有sping创建的，则dwr和Spring集成，dwr配置为：
