Using my debugger in Jackson2JsonMessageConverter.fromMessage() , the MessageProperties states the __TypeID__ is correctly set to java.util.ArrayList . However the __ContentTypeId__ is java.lang.Object is incorrect as I would be expecting FooDto (I assume...). The exception message is: java.lang.ClassCastException:

Rabbitmq: Unacked message not going away after broker restart

由 微笑、不失礼 提交于 2019-12-11 02:31:08
问题 We have observed the following behavior of RabbitMQ and are trying to understand if it is correct and how to resolve it. Scenario: A (persistent) message is delivered into a durable queue The (single) Consumer (Spring-AMQP) takes the message and starts processing => Message goes from READY to UNACK Now the broker is shut down => Client correctly reports "Channel shutdown" The consumer finishes the processing, but can not acknowledge the message as the broker is still down Broker is started

Designing Complex Notification system in spring

由 心已入冬 提交于 2019-12-08 07:23:09
问题 I want to design and implement a complex notification system where I have a user which will be automatically and manually subscribed to different events. After some research I made up my mind to go with websockets for pushing the notifications to client, and for subscribing the events I would go for RabbitMQ specifically I would go for direct exchange. At first thoughts I was thinking after establishing the websocket connection I would send the userId which will be subscribed with the

Return message to the end of queue in rabbitmq

由 北慕城南 提交于 2019-12-08 06:19:09
问题 I have exchange and queue. Producer doesn't need consumption confirmation, but messages in some cases can be un-processable by consumer in current moment, because of lack of other data. Because of this, I want to return those messages to the end of queue. How to do this? Or is it done automatically when I reject message? Flow: Message1 gets consumed and creates some record in database. Message2 gets consumed and checks if there is record in database, and if yes, then it updates the record. If

Automatic retry connection to broker by spring-rabbitmq

由 孤者浪人 提交于 2019-12-07 08:20:27
问题 I have read this fragment of docs: RabbitMQ Automatic Connection/Topology recovery Since the first version of Spring AMQP, the framework has provided its own connection and channel recovery in the event of a broker failure. Also, as discussed in Section 3.1.10, “Configuring the broker”, the RabbitAdmin will re-declare any infrastructure beans (queues etc) when the connection is re-established. It therefore does not rely on the Auto Recovery that is now provided by the amqp-client library.
