MessagingMessageListenerAdapter.MessagingMessageConverterAdapter (Spring AMQP 2.4.17 API)

java.lang.Object
- org.springframework.amqp.support.converter.MessagingMessageConverter
- - org.springframework.amqp.rabbit.listener.adapter.MessagingMessageListenerAdapter.MessagingMessageConverterAdapter

All Implemented Interfaces:

MessageConverter, InitializingBean

Enclosing class:

MessagingMessageListenerAdapter
```
protected final class MessagingMessageListenerAdapter.MessagingMessageConverterAdapter
extends MessagingMessageConverter
```
Delegates payload extraction to AbstractAdaptableMessageListener.extractMessage(org.springframework.amqp.core.Message message) to enforce backward compatibility. Uses this listener adapter's converter instead of the one configured in the converter adapter. If the inbound message has no type information and the configured message converter supports it, we attempt to infer the conversion type from the method signature.
