- org.springframework.web.socket.handler.WebSocketSessionDecorator
- - org.springframework.web.socket.handler.ConcurrentWebSocketSessionDecorator

所有已实现的接口:
Closeable, AutoCloseable, WebSocketSession
```
public class ConcurrentWebSocketSessionDecorator
extends WebSocketSessionDecorator
```
Wrap a WebSocketSession to guarantee only one thread can send messages at a time.
If a send is slow, subsequent attempts to send more messages from other threads will not be able to acquire the flush lock and messages will be buffered instead. At that time, the specified buffer-size limit and send-time limit will be checked and the session will be closed if the limits are exceeded.
从以下版本开始:

public ConcurrentWebSocketSessionDecorator(WebSocketSession delegate,
                                           int sendTimeLimit,

```
    Create a new ConcurrentWebSocketSessionDecorator.
    参数:
    delegate - the WebSocketSession to delegate to
    sendTimeLimit - the send-time limit (milliseconds)
    bufferSizeLimit - the buffer-size limit (number of bytes)

  - getSendTimeLimit
```
public int getSendTimeLimit()
```
    Return the configured send-time limit (milliseconds).
    从以下版本开始:
    4.3.13
  - getBufferSizeLimit
```
public int getBufferSizeLimit()
```
    Return the configured buffer-size limit (number of bytes).
    从以下版本开始:
    4.3.13
  - getBufferSize
```
public int getBufferSize()
```
    Return the current buffer size (number of bytes).
  - getTimeSinceSendStarted
```
public long getTimeSinceSendStarted()
```
    Return the time (milliseconds) since the current send started, or 0 if no send is currently in progress.
  - sendMessage
```
public void sendMessage(WebSocketMessage<?> message)
                 throws IOException
```
    从接口复制的说明: WebSocketSession
    Send a WebSocket message: either TextMessage or BinaryMessage.
    Note: The underlying standard WebSocket session (JSR-356) does not allow concurrent sending. Therefore sending must be synchronized. To ensure that, one option is to wrap the WebSocketSession with the ConcurrentWebSocketSessionDecorator.
    指定者:
    sendMessage 在接口中 WebSocketSession
    覆盖:
    sendMessage 在类中 WebSocketSessionDecorator
    抛出:
    IOException

  - close

```
    从接口复制的说明: WebSocketSession
    Close the WebSocket connection with the given close status.
    指定者:
    close 在接口中 WebSocketSession
    覆盖:
    close 在类中 WebSocketSessionDecorator
    抛出:

  - toString
```
public String toString()
