Class MessagingMessageConverterAdapter

java.lang.Object

org.springframework.amqp.support.converter.MessagingMessageConverter

org.springframework.amqp.support.converter.MessagingMessageConverterAdapter

All Implemented Interfaces:

MessageConverter, InitializingBean

public class MessagingMessageConverterAdapter
extends MessagingMessageConverter

The MessagingMessageConverter extension for message listeners with flexible method signature.

If the inbound message has no type information and the configured message converter supports it, this converter attempts to infer the conversion type from the method signature and populates the MessageProperties.setInferredArgumentType(Type) before calling extractPayload(org.springframework.amqp.core.Message) of super class.

If an instance is created without the bean method to infer the type from, it acts as a super class.

4.1
