Spring Messaging 6.1.4 · org.springframework.messaging.handler.annotation.support.DefaultMessageHandlerMethodFactory

The default MessageHandlerMethodFactory implementation creating an InvocableHandlerMethod with the necessary HandlerMethodArgumentResolver instances to detect and process most of the use cases defined by MessageMapping.

Extra method argument resolvers can be added to customize the method signature that can be handled.

By default, the validation process redirects to a no-op implementation, see setValidator(Validator) to customize it. The ConversionService can be customized in a similar manner to tune how the message payload can be converted

public void	setArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) Configure the complete list of supported argument types effectively overriding the ones configured by default.

A `BeanFactory` only needs to be available for placeholder resolution in handler method arguments; it's optional otherwise.
public void	setConversionService(ConversionService conversionService) Set the `ConversionService` to use to convert the original message payload or headers.
public void	setCustomArgumentResolvers(List<HandlerMethodArgumentResolver> the list of resolvers (never `null`) customArgumentResolvers) Set the list of custom `HandlerMethodArgumentResolver`s that will be used after resolvers for supported argument type.
public void	setMessageConverter(MessageConverter messageConverter) Set the `MessageConverter` to use.
public void	setValidator(Validator validator) Set the Validator instance used for validating `@Payload` arguments.
