Description:

A component required a bean named 'SYNC_XGT_USER_UPDATED' that could not be found.


Action:

Consider defining a bean named 'SYNC_XGT_USER_UPDATED' in your configuration.

问题分析

其实这个错误就是没有配置@EnableBinding(value = { XXXProcessor.class })，而却在监听类上配置了@StreamListener(“SYNC_XGT_USER_UPDATED”)导致的，错误比较低级，但是介于spring cloud stream网上资料较少，就把错误粘贴出来，也许能帮到你

使用spring cloud stream配置注意事项

这里注意的是使用spring cloud stream 时一定要注意三处配置：

1. 定义Channel接口时，注意@Input标记下的方法返回值是SubscribableChannel类用来接收消息渠道定义，@Output标记的方法下返回值MessageChannel类用户生产消息，定义好后需要使用@EnableBinding（value={xxx.class}）配置开启。
2. 在application.yml（当然你可以是.properties文件）配置你的channel，其实这里对于rabbitmq来说即使是在配置Bind，其下一般配置三个参数destination、group、content-type 对于rabbitmq，destination就是交换机名称，group就是队列（队列名字会变成destination+group的值），content-type用来指定数据交互的格式类型了，如果你想配置使用路由配置
   
spring:cloud:stream:rabbit: bindings:你的消息接收的Channel名字: consumer:bindingRoutingKey:路由值

3. 定义你的监听类，在方法上使用@StreamListener(“你的消息接收的Channel名字”)，在监听类上加上@Component注解

好了，就先说这么多，后面我们会写单独的连载文章介绍关于spring cloud stream rabbitMq的使用，如果你在使用spring cloud stream rabbit时有什么不清楚，可以留言或加关注私聊我，很愿意为你解答。
