验证过程

1. 应用启动,启动成功后,找到如下类似信息

`o.s.i.a.i.AmqpInboundChannelAdapter : started inbound.input.anonymous.bdmVXsWqSROwcFGGI3t4Sw`

2. 登录 RabbitMQ 控制台,比如

[http://localhost:6527/](http://localhost:6527/)

3. 选择 Queues Tab, 点击之前生成的queue Name

`inbound.input.anonymous.bdmVXsWqSROwcFGGI3t4Sw`

4. 点击 Publish message, payload 内容为

`{"name":"Sam Spade"}`

4. 点击 Publish message按钮,进行消息发布,即可在控制台打印

`Sam Spade`

导出jar到lib命令

mvn dependency:copy-dependencies -DoutputDirectory=lib
