所有已实现的接口:
SubProtocolCapable, WebSocketHandler
```
public class SockJsWebSocketHandler
extends TextWebSocketHandler
implements SubProtocolCapable
```
An implementation of WebSocketHandler that adds SockJS messages frames, sends SockJS heartbeat messages, and delegates lifecycle events and messages to a target WebSocketHandler.
Methods in this class allow exceptions from the wrapped WebSocketHandler to propagate. However, any exceptions resulting from SockJS message handling (e.g. while sending SockJS frames or heartbeat messages) are caught and treated as transport errors, i.e. routed to the handleTransportError method of the wrapped handler and the session closed.

```
    从接口复制的说明: WebSocketHandler
    Invoked after the WebSocket connection has been closed by either side, or after a transport error has occurred. Although the session may technically still be open, depending on the underlying implementation, sending messages at this point is discouraged and most likely will not succeed.
    指定者:
    afterConnectionClosed 在接口中 WebSocketHandler
