Serialize DTO out of Spring Boot but deserialize it in Spring Boot

I have one module (let's call it Producer) which cannot depend on Spring Boot. It sends Messages to ActiveMQ:

MyCustomDto msg = ...
String json = new ObjectMapper().writeValueAsString(msg); // this is where my I serialize the object to json
TextMessage message = session.createTextMessage(json); // activeMQ session
producer.send(message); // activeMQ producer

Another Module (Consumer) is a Spring Boot service and reads the Messages from ActiveMQ:

@JmsListener(destination = "topic1")
public void processToDo(MyCustomDto amqMessage) {
    log.info("I just received a message");
}

Notice that both - the message which was sent and the message which was received - should be a MyCustomDto and should therefore be compatible. This is the exception:

org.springframework.jms.listener.adapter.ListenerExecutionFailedException: Listener method could not be invoked with incoming message
Endpoint handler details:
Method [public void ...Consumer.processToDo(MyCustomDto)]
Bean [...Consumer@2d5399b4]
; nested exception is org.springframework.messaging.converter.MessageConversionException: Cannot convert from [java.lang.String] to [MyCustomDto] for org.springframework.jms.listener.adapter.AbstractAdaptableMessageListener$MessagingMessageConverterAdapter$LazyResolutionMessage@a882178, failedMessage=org.springframework.jms.listener.adapter.AbstractAdaptableMessageListener$MessagingMessageConverterAdapter$LazyResolutionMessage@a882178

which makes sense because TextMessage is a String (a JSON-String though) but a MyCustomDto Object is expected.

Is there a way to serialize the DTO by hand so Spring Boot can map it automatically?
