```
boolean canEncode(ResolvableType elementType,
                  @Nullable
                  MimeType mimeType)
```
    Whether the encoder supports the given source element type and the MIME type for the output stream.
    参数:
    elementType - the type of elements in the source stream
    mimeType - the MIME type for the output stream (can be null if not specified)
    返回:
    true if supported, false otherwise

```
    Encode a stream of Objects of type T into a DataBuffer output stream.
    参数:
    inputStream - the input stream of Objects to encode. If the input should be encoded as a single value rather than as a stream of elements, an instance of Mono should be used.
    bufferFactory - for creating output stream DataBuffer's
    elementType - the expected type of elements in the input stream; this type must have been previously passed to the canEncode(org.springframework.core.ResolvableType, org.springframework.util.MimeType) method and it must have returned true.
    mimeType - the MIME type for the output content (optional)
    hints - additional information about how to encode
    返回:
    the output stream
  - encodeValue
```
default DataBuffer encodeValue(T value,
                               DataBufferFactory bufferFactory,
                               ResolvableType valueType,

                               Map<String,Object> hints)
```
    Encode an Object of type T to a data buffer. This is useful for scenarios, that distinct messages (or events) are encoded and handled individually, in fully aggregated form.
    By default this method raises UnsupportedOperationException and it is expected that some encoders cannot produce a single buffer or cannot do so synchronously (e.g. encoding a Resource).
    参数:
    value - the value to be encoded
    bufferFactory - for creating the output DataBuffer
    valueType - the type for the value being encoded
    mimeType - the MIME type for the output content (optional)
    hints - additional information about how to encode
    返回:
    the encoded content

  - getEncodableMimeTypes
```
List<MimeType> getEncodableMimeTypes()
```
    Return the list of mime types this encoder supports.
