公司的項目裏使用了dwr ，一個 Ajax 的框架，於是乎，學習一下，
①，配置web.xml文件
<?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>
<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>
</web-app>
②，編寫 dwr.xml 文件
把dwr.xml文件放在web.xml文件同目錄下面
<?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 creator="new" javascript="Demo">
<param name="class" value="com.dwrTest.Hello"/>
</create>
</allow>
</dwr>
③，編寫 java 文件
package com.dwrTest;
/**

public class Hello {
public String hi(String youName){
return "你好,"+youName+" 這裏是 dwr 學校";
}
}
