本文主要是介绍批量生产千万级数据 推送到kafka代码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1、批量规则生成代码
1、随机IP生成代码
2、指定时间范围内随机日期生成代码
3、随机中文名生成代码。

}2. 生成对象体
package com.wfg.flink.connector.dto;import lombok.Data;/*** @author wfg*/
@Data
public class KafkaPvDto {// uuidprivate String uuid;// 用户名private String userName;// 访问时间private String visitTime;// 访问地址private String visitIp;// 访问服务IPprivate String visitServiceIp;
}3. 批量数据生成推送代码

}
注意：
kafka本机运行请参考： kafka本地部署链接
