Read JSON config file and make appropriate migration based on the definitions on the RabbitMQ server-CodePudding

Let's say that I have in my Spring project a predefined JSON file that is consisted of all the queue names on my RabbitMQ server, but with some modifications.

Example: RabbitMQ server state before migration:

Queue1
Queue2
Queue3

JSON config file:

Queue1
Queue2
Queue3Renamed
Queue4New

RabbitMQ server state after the migration:

Queue1
Queue2
Queue3Renamed
Queue4New

After the migration , some Queue's need to be updated(the name for example) or maybe a new queue needs to be created on the server, depends on the definitions in the JSON file. Also, another thing to bear in mind that is if a queue needs to be renamed, it may contain messages which mustn't be deleted.

Any ides on how to approach this problem?

CodePudding user response：

You cannot "rename" queues; they are immutable; you can only create new ones.

You can use the RabbitMQ rest API to examine the current configuration and a RabbitAdmin to declare new queues.
