我在春天的兔子消费者方面一直收到以下警告。它一直在寻找重启。

Answer 1

如果您看到以下例外

java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:189) at java.net.SocketInputStream.read(SocketInputStream.java:121) at java.io.BufferedInputStream.fill(BufferedInputStream.java:246) at java.io.BufferedInputStream.read(BufferedInputStream.java:265) at java.io.DataInputStream.readUnsignedByte(DataInputStream.java:288) at com.rabbitmq.client.impl.Frame.readFrom(Frame.java:95) at com.rabbitmq.client.impl.SocketFrameHandler.readFrame(SocketFrameHandler.java:139) at com.rabbitmq.client.impl.AMQConnection$MainLoop.run(AMQConnection.java:532)

这意味着您正在关闭消费者，而不是停止消费者。

Answer 2

SimpleMessageListenerContainer - 消费者引发异常，如果连接工厂支持，则处理可以重新启动
