【WEB 系列】SpringBoot2.3 整合 InfluxDB 实现增删查-工具盒子

概述: {#概述}

InfluxDB 是一个用于存储和分析时间序列数据的开源数据库。因为公司项目需求，记录一下使用过程

主要特性有：

内置 HTTP 接口，使用方便
数据可以打标记，这样查询可以很灵活
类 SQL 的查询语句
安装管理很简单，并且读写数据很高效
能够实时查询，数据在写入时被索引后就能够被立即查出

在最新的 DB-ENGINES 给出的时间序列数据库的排名中，InfluxDB 高居第一位，可以预见，InfluxDB 会越来越得到广泛的使用。相关介绍可以看我之前写的一篇关于 InfluxDB 的文章及安装操作InfluxDB 传送门

SpringBoot 整合 Influx {#SpringBoot 整合 Influx}

这里使用的是 SpringBoot 2.3.5.RELEASE，本地需要安装 influxdb-1.8.3-1，接下来看看如何实现的。
