使用influxdb-client-java查询InfluxDB数据是一个常见的操作。以下是如何使用influxdb-client-java库来查询InfluxDB数据的详细步骤和示例代码。 步骤 添加依赖: 首先,确保你的项目中已经添加了influxdb-client-java的依赖。如果你使用的是Maven,可以在pom.xml中添加如下依赖: xml <dependency> <groupId>...
在这一步骤中,我们将创建一个 InfluxDB 客户端实例以便与数据库进行通信: importorg.influxdb.InfluxDB;importorg.influxdb.InfluxDBFactory;// 创建 InfluxDB 客户端实例InfluxDBinfluxDB=InfluxDBFactory.connect("http://localhost:8086","username","password");// 连接到指定的 InfluxDB 实例 1. 2. 3. 4...
首先,确保你的开发环境中已经安装了Java和Maven。然后,在你的pom.xml文件中添加InfluxDB Java客户端的依赖: <dependency><groupId>org.influxdb</groupId><artifactId>influxdb-java</artifactId><version>2.22</version></dependency> 1. 2. 3. 4. 5. 连接InfluxDB 在使用InfluxDBClient之前,需要先建立与Inf...

I have been using InfluxDB v1.x for nearly 1.5 years now. Recently, we started exploring InfluxDB v2.0. However, in the initial analysis it seems that the v2.0 write performance or the WriteApi in influxdb-client-java for v2/0, substantially underperforms compared to an older version lik...
A lot of our codebase is using org.influxdb:influxdb-java:2.15 (which is for influxDB 1.x). According to the github page, it should also work with the backwards compatibility API of influxDB 2.7. However, I can’t get i…
