- org.springframework.web.socket.adapter.standard.ConvertingEncoderDecoderSupport<T,M>

类型参数:
T - the type being converted to (for Encoder) or from (for Decoder)
M - the WebSocket message type (String or ByteBuffer)
直接已知子类:
ConvertingEncoderDecoderSupport.BinaryDecoder, ConvertingEncoderDecoderSupport.BinaryEncoder, ConvertingEncoderDecoderSupport.TextDecoder, ConvertingEncoderDecoderSupport.TextEncoder
```
public abstract class ConvertingEncoderDecoderSupport<T,M>
extends Object
```
Base class that can be used to implement a standard Encoder and/or Decoder. It provides encode and decode method implementations that delegate to a Spring ConversionService.
By default, this class looks up a ConversionService registered in the active ApplicationContext under the name 'webSocketConversionService'. This works fine for both client and server endpoints, in a Servlet container environment. If not running in a Servlet container, subclasses will need to override the getConversionService() method to provide an alternative lookup strategy.
Subclasses can extend this class and should also implement one or both of Encoder and Decoder. For convenience ConvertingEncoderDecoderSupport.BinaryEncoder, ConvertingEncoderDecoderSupport.BinaryDecoder, ConvertingEncoderDecoderSupport.TextEncoder and ConvertingEncoderDecoderSupport.TextDecoder subclasses are provided.
Since JSR-356 only allows Encoder/Decoder to be registered by type, instances of this class are therefore managed by the WebSocket runtime, and do not need to be registered as Spring Beans. They can, however, by injected with Spring-managed dependencies via @Autowire.
Converters to convert between the type and String or ByteBuffer should be registered.

  - init

public void init(EndpointConfig config)

  - destroy

    另请参阅:
    Encoder.destroy(), Decoder.destroy()
  - getConversionService
```
protected ConversionService getConversionService()
```
    Strategy method used to obtain the ConversionService. By default this method expects a bean named 'webSocketConversionService' in the active ApplicationContext.
    返回:
    the ConversionService (never null)
  - getApplicationContext
```
protected ApplicationContext getApplicationContext()
```
    Returns the active ApplicationContext. Be default this method obtains the context via ContextLoader.getCurrentWebApplicationContext(), which finds the ApplicationContext loaded via ContextLoader typically in a Servlet container environment. When not running in a Servlet container and not using ContextLoader, this method should be overridden.
    返回:
    the ApplicationContext or null
  - getType
```
protected TypeDescriptor getType()
```
    Returns the type being converted. By default the type is resolved using the generic arguments of the class.
  - getMessageType
```
protected TypeDescriptor getMessageType()
```
    Returns the websocket message type. By default the type is resolved using the generic arguments of the class.
  - encode
```
public M encode(T object)
         throws EncodeException
```
    抛出:
