能正常发送，当把上面的注释放开后，则不能发送消息，报如下错误：
com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg ‘x-message-ttl‘ for queue ‘top.name3‘ in vhost ‘/‘: received the value ‘10000‘ of type ‘long‘ but current is none, class-id=50, method-id=10) at com.rabbitmq.client.impl.ChannelN.asyncShutdown(ChannelN.java:516) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.ChannelN.processAsync(ChannelN.java:346) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.AMQChannel.handleCompleteInboundCommand(AMQChannel.java:178) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.AMQChannel.handleFrame(AMQChannel.java:111) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.AMQConnection.readFrame(AMQConnection.java:670) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.AMQConnection.access$300(AMQConnection.java:48) ~[amqp-client-5.4.3.jar:5.4.3] at com.rabbitmq.client.impl.AMQConnection$MainLoop.run(AMQConnection.java:597) ~[amqp-client-5.4.3.jar:5.4.3] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_92]
