RabbitMq 本地连接报错 org.springframework.amqp.AmqpIOException: java.io.IOException

前言

上一篇博客讲述了ubuntu 16.04上如何安装RabbitMq，并通过web管理界面远程访问。
紧接着我在自己搭建的spring boot项目中，整合了RabbitMq，本地启动项目，发现控制台一直报错。。。

项目启动报错

org.springframework.amqp.AmqpIOException: java.io.IOException….

具体报错如下截图：

问题分析

其实在我上一家公司，开发过程中，本地启动项目也会一直报这个错！！

首先，我确定rabbitmq正常启动了，可以远程访问，且项目中配置文件是正确的：

#  rabbitmq:
#    host: 127.0.0.1
#    port: 5672
#    virtual-host: /
#    username: guest # 默认的guest用户
#    password: guest
  rabbitmq:
      host: 132.232.54.106   # 服务器IP
      port: 5672    # 端口
      virtual-host: /
      username: demo   #新增用户名
      password: demo

将rabbitmq主机改为127.0.0.1，username：guest。然后将项目打成war包，放到安装rabbitmq的服务器上面运行。
启动成功后，本地浏览器访问项目swagger接口，并调用测试接口，查看日志，是ok的。

经过一番百度，最终得到的解决办法：
将rabbitmq新增的用户授权就可以了。具体解决办法如下：

操作步骤：
1.打开RabbitMq web管理界面，进入该页面，点击用户名称

2.点击 set premission 按钮，就ok了

over，这个时候再去本地启动一下项目，使用这个用户。。是不是发现就没报错了。QAQ
最后说一下，rabbitmq的这个可视化工具还是挺好用的。
