所有已实现的接口:
HttpMessageConverter<byte[]>
```
public class ByteArrayHttpMessageConverter
extends AbstractHttpMessageConverter<byte[]>
```
Implementation of HttpMessageConverter that can read and write byte arrays.
By default, this converter supports all media types (*/*), and writes with a Content-Type of application/octet-stream. This can be overridden by setting the supportedMediaTypes property.

  - supports
```
public boolean supports(Class<?> clazz)
```
    从类复制的说明: AbstractHttpMessageConverter
    Indicates whether the given class is supported by this converter.
    指定者:
    supports 在类中 AbstractHttpMessageConverter<byte[]>
    参数:
    clazz - the class to test for support
    返回:
    true if supported; false otherwise
  - readInternal
```
public byte[] readInternal(Class<? extends byte[]> clazz,
                           HttpInputMessage inputMessage)
                    throws IOException
