reply-code=530, reply-text=NOT_ALLOWED - access to vhost '/' refused for user user_admin

本文主要是介绍reply-code=530, reply-text=NOT_ALLOWED - access to vhost '/' refused for user user_admin，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Java使用amqp-client连接rabbitmq服务端，报出如下异常

Exception in thread "main" java.io.IOExceptionat com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:105)at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:101)at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:123)at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:377)at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:824)at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:778)at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:868)at rq.Producer.main(Producer.java:30)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:498)at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147)

定位发现是连接rabbitmq使用的用户没有赋予访问权限，我创建的是admin用户，给admin用户赋予‘/’目录的访问权限就可以，执行如下命令：

sudo rabbitmqctl  set_permissions -p / admin '.*' '.*' '.*'
