spring整合DWR步骤简单说明
一、导入dwr包【dwr.jar】并在web.xml中添加如下代码
<listener><listener-class>org.directwebremoting.servlet.DwrListener</listener-class></listener><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><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dwr-invoker</servlet-name><url-pattern>/dwr/*</url-pattern></servlet-mapping>
二、编写service类，如下
package cn.com.songjy.service;import org.springframework.stereotype.Service;@Service("dwrService")public class DwrService {public String hello(String name){return "你好," + name;}public String hello_1(String name){return "Hello," + name;}public String getName(String name){return name;}}三、在WEB-INF目录下创建dwr.xml文件，如下
<?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><!-- DwrServiceJs是页面引用时要用到的名称 --><create creator="spring" javascript="DwrServiceJs"><!-- dwrService是spring注入cn.com.songjy.service.DwrService类时名称 --><param name="beanName" value="dwrService" /><!-- 对外公布方法列表，当须全部公布时，则无需配置include --><include method="hello"/><include method="hello_1"/></create></allow></dwr>
四、编写页面脚本测试【dwr.jsp】，如下
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title><script type="text/javascript" src="<%=request.getContextPath()%>/dwr/engine.js"></script><script type="text/javascript" src="<%=request.getContextPath()%>/dwr/interface/DwrServiceJs.js"></script></head><script type="text/javascript">DwrServiceJs.hello("张三", function(data){alert(data);});</script><body></body></html>最后访问【dwr.jsp】即可测试！
