Spring amqp: How can I read MessageProperties in MessageListenerAdapter

Question

handleMessage method does not get the message from queue if I add MessageProperties in its signature. It works fine if there is no MessageProperties.

How can I get MessageProperties in handleMessage of MessageListenerAdapter?

public class EventMessageAdapter {

  public void handleMessage(MessageProperties messageProperties, Event event)    {
  ...
  String id = messageProperties.getHeaders().get("key");
}

Answer 1

You can't do it with the listener adapter.

Use the newer-style @RabbitListener mechanism docs here.

You can use various signatures...

@RabbitListener(queues = "foo")
public void foo(Event event, @Header("foo") String fooHeader, 
           @Header("bar") Integer barHeader) {...}

or

@RabbitListener(queues = "bar")
public void bar(Event event, Message message) {...}

In the second case you can get all the message properties via message.getMessageProperties().

You need a container factory. Spring Boot creates one automatically for you if the starter is on the classpath.
