java.lang.Object
- org.springframework.web.socket.handler.PerConnectionWebSocketHandler

所有已实现的接口:
Aware, BeanFactoryAware, WebSocketHandler
```
public class PerConnectionWebSocketHandler
extends Object
implements WebSocketHandler, BeanFactoryAware
```
A WebSocketHandler that initializes and destroys a WebSocketHandler instance for each WebSocket connection and delegates all other methods to it.
Essentially create an instance of this class once, providing the type of WebSocketHandler class to create for each connection, and then pass it to any API method that expects a WebSocketHandler.
If initializing the target WebSocketHandler type requires a Spring BeanFctory, then the setBeanFactory(BeanFactory) property accordingly. Simply declaring this class as a Spring bean will do that. Otherwise, WebSocketHandler instances of the target type will be created using the default constructor.

public void setBeanFactory(BeanFactory beanFactory)
```
    从接口复制的说明: BeanFactoryAware
    Callback that supplies the owning factory to a bean instance.
    Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.
    指定者:
    setBeanFactory 在接口中 BeanFactoryAware
    参数:
    beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
    另请参阅:
    BeanInitializationException
  - afterConnectionEstablished
```
public void afterConnectionEstablished(WebSocketSession session)
                                throws Exception
```
    从接口复制的说明: WebSocketHandler
    Invoked after WebSocket negotiation has succeeded and the WebSocket connection is opened and ready for use.
    指定者:
    afterConnectionEstablished 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - handleMessage
```
public void handleMessage(WebSocketSession session,
                          WebSocketMessage<?> message)
                   throws Exception
```
    从接口复制的说明: WebSocketHandler
    Invoked when a new WebSocket message arrives.
    指定者:
    handleMessage 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - handleTransportError
```
public void handleTransportError(WebSocketSession session,
                                 Throwable exception)
                          throws Exception
```
    从接口复制的说明: WebSocketHandler
    Handle an error from the underlying WebSocket message transport.
    指定者:
    handleTransportError 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - afterConnectionClosed
```
public void afterConnectionClosed(WebSocketSession session,
                                  CloseStatus closeStatus)
                           throws Exception
```
    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
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - supportsPartialMessages
```
public boolean supportsPartialMessages()
```
    从接口复制的说明: WebSocketHandler
    Whether the WebSocketHandler handles partial messages. If this flag is set to true and the underlying WebSocket server supports partial messages, then a large WebSocket message, or one of an unknown size may be split and maybe received over multiple calls to WebSocketHandler.handleMessage(WebSocketSession, WebSocketMessage). The flag WebSocketMessage.isLast() indicates if the message is partial and whether it is the last part.
    指定者:
    supportsPartialMessages 在接口中 WebSocketHandler
  - toString
```
public String toString()
```
    覆盖:
    toString 在类中 Object
