来源：互联网发布：k60单片机编程用什么编辑：程序博客网时间：2024/06/05 04:48

1.引入dwr.jar和commons-logging-1.0.4.jar

2.修改Web.xml 添加
    <servlet>
    <servlet-name>dwraaa</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>dwraaa</servlet-name>
    <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

3.编写dwr.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 3.0//EN" "http://getahead.org/dwr/dwr30.dtd">
<dwr>
<allow>
  <create creator="new" javascript="HahaDemo1">
       <param name="class" value="com.haha.action.Demo1"/>
  </create>
  
  
  <convert converter="exception" match="java.lang.Exception"/>
  <convert converter="bean" match="java.lang.StackTraceElement"/>
</allow>
</dwr>

添加业务类
<create creator="new" javascript="js访问的类名">
<param name="class" value="对应的java类"/>
</create>
添加实体类
<convert converter="bean" match="java的实体类"/>

4.在jsp或html中使用
4.1 引入JS
<script type='text/javascript' src='dwr/engine.js'> </script>
<script type='text/javascript' src='dwr/util.js'> </script>
<script type='text/javascript' src='dwr/interface/[dwr.xml中所配置的js访问类名].js'> </script>

js访问的类名.方法(参数1,参数2...,callbackJs[回调函数]);
