不断进步中 04-09 158

前言：

现在看官们对“bus集成apachekafka”大体比较看重，朋友们都想要剖析一些“bus集成apachekafka”的相关知识。那么小编也在网摘上搜集了一些关于“bus集成apachekafka””的相关知识，希望我们能喜欢，大家快快来了解一下吧！

框架学习整理记录下日常spring boot开发Kafka下面涉及的文件类;1、QiDongManagerApp.java 启动类处理 ,2、application.yml 配置文件,3、TestCommandBusProduce.java 生产者接口，4、TestCommandBusProduceImpl.java 生产者接口实现类,5、TestCommandBusConsumer.java 总线消费者,6、TestCommandBusListener.java业务场景监听处理逻辑7、maven下pom.xml集成kafka包
