---------------------在jsp页面中加入----------------------
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<base href="<%=basePath%>">
//从官网下载
<script type="text/javascript" src="<%=path%>/cc/util/js/ajax-pushlet-client.js"></script>
<script type="text/javascript">
PL._init();
//监听mutiSend时间,mutiSend是我定义的
PL.joinListen(‘/mutiSend‘);
function onData(event) {
try{
//读取内容
var context=event.get("msg");
//解决汉字乱码问题
context=decodeURIComponent(context);
if(null!=context&&"undefined"!=context){
//var a=document.getElementById("contex");
//a.innerHTML=context;
pushInfoShowDiv(context);
}
}catch(e){
}
// 离开
// PL.leave();
}
</script>
--------------------------web.xml文件中加入
<!-- pushlet --> <servlet> <servlet-name>pushlet</servlet-name> <servlet-class>nl.justobjects.pushlet.servlet.Pushlet</servlet-class> <load-on-startup>3</load-on-startup> </servlet> <servlet-mapping> <servlet-name>pushlet</servlet-name> <url-pattern>/pushlet.srv</url-pattern> </servlet-mapping>
------------------------java文件-----------------
//向所有和****名称匹配的事件进行推送 public void mutiSend(){ try { //获得数据 List<RemindInfo> list = retrieve(null,null,null,null,null); String remindContent=""; if(null!=list&&0!=list.size()){ remindContent=list.get(0).getRemindContent(); } Event event =Event.createDataEvent("/mutiSend"); event.setField("msg", URLEncoder.encode(remindContent+"<br/>推送时间:"+new Date().toLocaleString(),"UTF-8"));//解决乱码 Dispatcher.getInstance().multicast(event); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
如果需要页面点击发送,然后推送给各个客户端,在action或者servlet中加入
Event event =Event.createDataEvent("/mutiSend");
event.setField("msg", URLEncoder.encode(remindContent+"<br/>推送时间:"+new Date().toLocaleString(),"UTF-8"));//解决乱码
Dispatcher.getInstance().multicast(event);
这三句代码即可
------------效果-------------
pushlet服务端推送
