我有正在侦听web-socket的应用程序作用域bean。收到消息后,我想更新咆哮。但是下面的内容不起作用,因为它不在请求/响应时间内。有可能这样做吗?
RequestContext.getCurrentInstance().update("growl");
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Message", "value"));
答案 0 :(得分:1)
您需要做的是将Bean中的PrimeFaces推送事件发送到所有客户端共享的常规websocket上的所有连接客户端。在那种情况下,您会发送一条消息,例如PrimeFaces push notify示例
public void send() {
EventBus eventBus = EventBusFactory.getDefault().eventBus();
eventBus.publish(CHANNEL, new FacesMessage(StringEscapeUtils.escapeHtml(summary), StringEscapeUtils.escapeHtml(detail)));
}
然后在页面中显示该消息
<p:growl widgetVar="growl" showDetail="true" />
<p:socket onMessage="handleMessage" channel="/notify" />
<script type="text/javascript">
function handleMessage(facesmessage) {
facesmessage.severity = 'info';
PF('growl').show([facesmessage]);
}
</script>
