Method Detail

supportsParameter

public final boolean supportsParameter(MethodParameter parameter)

Indicates whether the given method parameter is supported by this resolver.

This implementation gets checks if the given parameter is annotated with RequestPayload, and invokes supportsRequestPayloadParameter(org.springframework.core.MethodParameter) afterwards.

Specified by:

supportsParameter in interface MethodArgumentResolver

Parameters:

parameter - the method parameter to check

Returns:

true if this resolver supports the supplied parameter; false otherwise

supportsRequestPayloadParameter

protected abstract boolean supportsRequestPayloadParameter(MethodParameter parameter)

Indicates whether the given method parameter, annotated with RequestPayload, is supported by this resolver.

Parameters:

parameter - the method parameter to check

Returns:

true if this resolver supports the supplied parameter; false otherwise

supportsReturnType

public final boolean supportsReturnType(MethodParameter returnType)

Indicates whether the given method return type is supported by this handler.

This implementation gets checks if the method of the given return type is annotated with ResponsePayload, and invokes supportsResponsePayloadReturnType(org.springframework.core.MethodParameter) afterwards.

Specified by:

supportsReturnType in interface MethodReturnValueHandler

Parameters:

returnType - the method return type to check

Returns:

true if this handler supports the supplied return type; false otherwise

supportsResponsePayloadReturnType

protected abstract boolean supportsResponsePayloadReturnType(MethodParameter returnType)

Indicates whether the given method return type, annotated with ResponsePayload, is supported.

Parameters:

returnType - the method parameter to check

Returns:

true if this resolver supports the supplied return type; false otherwise

convertToByteArrayInputStream

protected ByteArrayInputStream convertToByteArrayInputStream(Source source)
                                                      throws TransformerException

Converts the given source to a byte array input stream.

Parameters:

source - the source to convert

Returns:

the input stream

Throws:

TransformerException - in case of transformation errors
