All Implemented Interfaces:
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.

    Indicates whether the given class is supported by this converter.
    Specified by:
    supports in class AbstractHttpMessageConverter<byte[]>
    Parameters:
    clazz - the class to test for support
    Returns:
    true if supported; false otherwise
  - readInternal
```
public byte[] readInternal(Class<? extends byte[]> clazz,
                           HttpInputMessage inputMessage)
                    throws IOException
```
    Description copied from class: AbstractHttpMessageConverter
    Abstract template method that reads the actual object. Invoked from AbstractHttpMessageConverter.read(java.lang.Class<? extends T>, org.springframework.http.HttpInputMessage).
    Specified by:
    readInternal in class AbstractHttpMessageConverter<byte[]>
    Parameters:
    clazz - the type of object to return
    inputMessage - the HTTP input message to read from
    Returns:
    the converted object
    Throws:

    Description copied from class: AbstractHttpMessageConverter
    Returns the content length for the given type.
    By default, this returns null, meaning that the content length is unknown. Can be overridden in subclasses.
    Overrides:

    Parameters:
    bytes - the type to return the content length for
    Returns:

    Abstract template method that writes the actual body. Invoked from AbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage).
    Specified by:
    writeInternal in class AbstractHttpMessageConverter<byte[]>
    Parameters:
    bytes - the object to write to the output message
    outputMessage - the HTTP output message to write to
    Throws:
    IOException - in case of I/O errors
