• java 网站用户在线和客服聊天



    注:本文来源于《java 网站用户在线和客服聊天



    这是应用到项目中的一个例子。

    实现原理是将信息存储到Application域里面。然后使用Struts2 Action 用json格式的数据进行前后台交互。

    前台用户界面:

    后台客服界面:

    编辑框采用的Ueditor 可以发送图片表情文字格式、涂鸦。。。。等等!功能十分的强大!

    代码部分:

    用到了两个Action,分别为用户和管理员服务。

    Struts.xml

    <!-- 聊天功能实现  -->
    	<package name="chat" extends="struts-default,json-default">
    		<!-- 用户发送消息  -->
    		<action name="chatMessageSend" class="com.shop.chat.MessageAction" method="send">
    			<result name="success" type="json"></result>
    		</action>
    
    		<!-- 用户接受消息  -->
    		<action name="chatMessageGet" class="com.shop.chat.MessageAction">
