DWR SSH Spring Hibernate Bean

几经周折，SSH集成DWR终于成功了。

struts2.0,spring2.5,hibernate3.0,dwr3.0.

下面，贴下我的配置文件。

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="spring" javascript="login" >
			
			
			<param name="beanName" value="com.lc.action.OperatorAction" />
		</create>
		
		<convert converter="bean" match="com.lc.domain.Operator" />
	</allow>
	
</dwr>

注意：dwr.xml的 <create creator="spring" javascript="login" > 要与页面引入的js文件名一致，比如<script src="dwr/interface/login.js"></script>，切要与spring配置文件里的<dwr:remote>标签引入的js名一致，见如下的配置。

在需要用到dwr的页面引入下面三个JS

JSP页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<script src="dwr/engine.js"></script>
	<script src="dwr/util.js"></script>
	<script src="dwr/interface/login.js"></script>
  </head>
  <script type="text/javascript">
  	function check() {
  		var id = document.getElementById("ope.user_id").value;
  		var password = document.getElementById("ope.user_pass").value;
  		
  		login.find(id,checkFun);
  	}
  	function checkFun(data) {
  		if(data)
  			alert("ok");
  		else
  			alert("failed"); 
  	}
  
  </script>
  <body>
  	
    <form action="login.action" method="post">
    	<input type="text" name="ope.user_id" id="ope.user_id" ><br>
    	<input type="password" name="ope.user_pass" onblur="check()"><br/>
    	<input type="submit" value="提交">
    </form>
  </body>
</html>

我的demo是用MyEclipse8.5开发的，下面把源代码，和所用到的jar包截图传上来，希望对大家有所帮助。
