Method Detail

resolveArgument

public final Object resolveArgument(MessageContext messageContext,
                                    org.springframework.core.MethodParameter parameter)
                             throws Exception

Description copied from interface: MethodArgumentResolver

Resolves the given parameter into a method argument.

Parameters:

messageContext - the current message context

parameter - the parameter to resolve to an argument. This parameter must have previously been passed to the MethodArgumentResolver.supportsParameter(MethodParameter) method of this interface, which must have returned true.

Returns:

the resolved argument. May be null.

Throws:

Exception - in case of errors

resolveRequestPayloadArgument

protected abstract Object resolveRequestPayloadArgument(org.springframework.core.MethodParameter parameter,
                                                        Source requestPayload)

Resolves the given parameter, annotated with RequestPayload, into a method argument.

Parameters:

parameter - the parameter to resolve to an argument

requestPayload - the request payload

Returns:

the resolved argument. May be null.

Throws:

Exception - in case of errors

handleReturnValue

public final void handleReturnValue(MessageContext messageContext,
                                    org.springframework.core.MethodParameter returnType,
                                    Object returnValue)
                             throws Exception

Description copied from interface: MethodReturnValueHandler

Handles the given return value.

Parameters:

messageContext - the current message context

returnType - the return type to handle. This type must have previously been passed to the MethodReturnValueHandler.supportsReturnType(MethodParameter) method of this interface, which must have returned true.

returnValue - the return value to handle

Throws:

Exception - in case of errors

createResponsePayload

protected abstract Source createResponsePayload(org.springframework.core.MethodParameter returnType,
                                                Object returnValue)
                                         throws Exception
