Wicket组件使用JMS侦听器自动刷新

Question

I am trying to create a notification panel using Wicket 7 and Spring boot 1.5.3 as backend. For notifications I am using JMS and ActiveMQ with Spring boot JMS with Spring Boot .

My question is how can I auto refresh (re-render/update) a wicket component as soon as a message comes in from my JMS Listener.

Answer 1

You have two options:

1. Use AbstractAjaxTimerBehavior and poll for updates every N seconds
2. Use WebSocketBehavior and push the updates whenever they come. See https://ci.apache.org/projects/wicket/guide/7.x/single.html#_native_websockets

Using WebSockets is recommended but depends whether your application is used by old browsers (IE9 and older).
