• 简单封装kafka相关的api


    一、针对于kafka版本

    <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-clients</artifactId>
        <version>0.8.2.2</version>
    
    </dependency>
    
    <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka_2.11</artifactId>
        <version>0.8.2.2</version>
    </dependency>

    二、操作topic、consumer相关方法
