Websockets、SockJs、Stomp、Spring、RabbitMQ，自动删除用户特定队列 [英] Websockets, SockJs, Stomp, Spring, RabbitMQ, delete User specific Queues automatically

问题描述

我希望有人可以帮助我解决这个问题.我正在使用带有 SockJs 和 StompJs 的 Spring 的 Websocket 支持.我订阅了这样的队列:

I hope someone can help me with this issue. I am using the Websocket support of Spring with SockJs and StompJs. I subscribed to a queue like this:

    var socket = new SockJS(localhost + 'websocket');
    stompClient = Stomp.over(socket);
    stompClient.connect('', '', function(frame) {
        stompClient.subscribe("/user/queue/gotMessage", function(message) {
            gotMessage((JSON.parse(message.body)));
        });
    }, function(error) {
    });

这对 Spring 的 SimpMessageSendingOperations 非常有效.但是有一个大问题.队列名称如下所示: gotMessage-user3w4tstcj 并且没有声明为自动删除队列，但这正是我想要的.否则，我有 10k 个未使用的队列.在队列没有消费者的那一刻，应该删除队列.我怎么能假设这个?

This works really fine with the SimpMessageSendingOperations of Spring. BUT there is one big problem. The Queue name looks like this: gotMessage-user3w4tstcj and it's not declared as an auto delete queue, but this is what I want. Otherwise, I have 10k unused queues. In that moment where the queue has no consumer, the queue should be deleted. How can I assume this?

推荐答案

有同样的问题，来自文档:

had same problem, from the documentation:

RabbitMQ 在目的地像使用/exchange/amq.direct/position-updates.所以在那种情况下客户端可以订阅/user/exchange/amq.direct/position-updates

RabbitMQ creates auto-delete queues when destinations like /exchange/amq.direct/position-updates are used. So in that case the client could subscribe to /user/exchange/amq.direct/position-updates

记得在 stomp 代理中继配置中添加/exchange/"作为目标前缀

remember to add '/exchange/' as a destination prefix in stomp broker relay configuration
