大气框架中的长轮询间隔约为60秒。即使在AtmosphereRequest中设置pollingInterval属性后,请求也会在60秒后发送到服务器。如何在请求中设置pollingInterval? 这是javascript中的请求: 请求:{         url:document.location.toString()+'echo',
        运输:'websocket',         fallbackTransport:'long-polling',         trackMessageLength:是的,         重新连接:是的,         pollingInterval:10,
        maxReconnectOnClose:Number.MAX_VALUE,
        reconnectInterval:10,         connectTimeout:-1 }

在服务器端,在web.xml中,您可以设置这两个init-param条目:

 <init-param>
    <param-name>org.atmosphere.cpr.AtmosphereInterceptor</param-name>        
    <param-value>org.atmosphere.interceptor.HeartbeatInterceptor</param-value>
 </init-param>
<init-param>
    <param-name>org.atmosphere.interceptor.HeartbeatInterceptor.heartbeatFrequencyInSeconds</param-name>
    <!-- value in seconds, default 60 -->
    <param-value>10</param-value>
 </init-param>
