1、 密码输入错误
Exception in thread "main" com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
解决办法：修改密码和服务器中账户密码一样： factory.setPassword(“1234”);
2、 启动错误
Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'ack_queue' in vhost '/': received 'true' but current is 'false', class-id=50, method-id=10)* at com.rabbitmq.client.impl.ChannelN.asyncShutdown(ChannelN.java:517)* at com.rabbitmq.client.impl.ChannelN.processAsync(ChannelN.java:341)* at com.rabbitmq.client.impl.AMQChannel.handleCompleteInboundCommand(AMQChannel.java:182)* at com.rabbitmq.client.impl.AMQChannel.handleFrame(AMQChannel.java:114)* at com.rabbitmq.client.impl.AMQConnection.readFrame(AMQConnection.java:739)* at com.rabbitmq.client.impl.AMQConnection.access$300(AMQConnection.java:47)* at com.rabbitmq.client.impl.AMQConnection$MainLoop.run(AMQConnection.java:666)* at java.lang.Thread.run(Thread.java:745)* 错误原因： RabbitMQ中之前队列启动过了，并且之前的是非持久化的，现在修改持久化后，RabbitMQ中的没有删除导致启动报错* 解决办法： 删除RabbitMQ中的队列，再启动
错误原因： RabbitMQ中之前队列启动过了，并且之前的是非持久化的，现在修改持久化后，RabbitMQ中的没有删除导致启动报错
解决办法： 删除RabbitMQ中的队列，再启动
3、 生产者没有开启
Exception in thread "main" java.io.IOException* Caused by: com.rabbitmq.client.ShutdownSignalException:channel error; protocol method: #method<channel.close>*(reply-code=404, reply-text=NOT_FOUND - no queue 'ask_queue' in vhost '/', class-id=60, method-id=20)
错误原因：生产者没有开启，或者生产者的队列名和此消费者的队列名QUEUE_NAME不同导致的
解决办法：开启生产者和修改队列名一样
4、 第三个参数为true报了如下错误
channel.queueDeclare(QUEUE_NAME,false,true,false,null);
解决办法：第三个参数修改为false
channel.queueDeclare(QUEUE_NAME,false,false,false,null);
第三个参数为true报了如下错误：* Exception in thread "main" java.io.IOException* at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:129)* at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:125)* at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:147)* at com.rabbitmq.client.impl.ChannelN.queueDeclare(ChannelN.java:968)* at com.rabbitmq.client.impl.recovery.AutorecoveringChannel.queueDeclare(AutorecoveringChannel.java:343)* at com.feng.rabbitmq.two.Task01.main(Task01.java:14)* Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=405, reply-text=RESOURCE_LOCKED - cannot obtain exclusive access to locked queue 'hello' in vhost '/'.
