推荐答案
您会要么需要使用的WebSockets 或客户方投票。
You'll either want to use WebSockets or clientside polling.
有几个Java库都来帮你提取从底层机制，可以回退到轮询的WebSockets，如果没有浏览器支持：
There's a few java libraries out there to help abstract you from the underlying mechanics which can fallback to polling if websockets are not supported by the browser:
- cometd
- atmosphere
- DWR's reverse-ajax
- spring mvc
我肯定还有更多但会得到您开始：）
Im sure there's more but that'll get you started :)
