Example 2 with AutorecoveringChannel

use of com.rabbitmq.client.impl.recovery.AutorecoveringChannel in project LinkAgent by shulieTech.

the class AutorecoveringChannelConsumerMetaDataBuilder method tryBuild.

@Override

    }
    /*
            如果一个connection有多个channel，这多个channel之间又有相同的consumer tag订阅不同的queue，那么这里就有问题。
            因为consumer_tag对于connection来说不是唯一的，对于channel才是唯一的，最早订阅的conusmer会被覆盖
            rabbitmq client的内部实现就是有bug，see : AutorecoveringConnection#recordConsumer，
            所以应该不太会出现重复consumer tag的情况，这里就先不考虑相同consumer tag在同一个connection的情况
