Spring 4中用于websocket的动态消息映射 [英] dynamic message-mapping for websockets in Spring 4

问题描述

我想在springs新的websocket/stomp支持下进行小型聊天. 我想我不能使用这样的东西:

I want to develop a small chat with springs new websocket/stomp support. I guess i cannot use something like this:

@MessageMapping("/connect/{roomId}")
@SendTo("/topic/newMessage")
public String connectToChatRoom(@PathVariable String roomId, Principal p) {
    return getTimestamp() + " " + p.getName() + " connected to the room.";
}

在这里，我有哪些动态映射选项?作为客户，我只想预订我所在的房间.

What are my options for dynamic mapping here? As a client i want to subscribe only to the room I'm in.

提前谢谢！

推荐答案

弄清楚了，您需要使用@DestinationVariable而不是@PathVariable

Figured it out, you need to use @DestinationVariable instead of @PathVariable
