Adding a Custom HandlerMethodArgumentResolver to @RabbitListener

Starting with version 2.3.7 you are able to add your own HandlerMethodArgumentResolver and resolve custom method parameters. All you need is to implement RabbitListenerConfigurer and use method setCustomMethodArgumentResolvers() from class RabbitListenerEndpointRegistrar.

@Configuration
class CustomRabbitConfig implements RabbitListenerConfigurer {

    @Override
    public void configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) {
        registrar.setCustomMethodArgumentResolvers(
				new HandlerMethodArgumentResolver() {

					@Override
					public boolean supportsParameter(MethodParameter parameter) {
						return CustomMethodArgument.class.isAssignableFrom(parameter.getParameterType());
					}

					@Override
					public Object resolveArgument(MethodParameter parameter, org.springframework.messaging.Message<?> message) {
						return new CustomMethodArgument(
								(String) message.getPayload(),
								message.getHeaders().get("customHeader", String.class)
						);
					}

				}
			);
    }

}
