1、添加依赖

</project>

2、添加配置文件

spring:
  influx:
    url: *
    password: admin
    user: 123
    database: test_data
  application:
    name: tire-net
server:
  port: 8081

package com.tire.net.configure;
import com.tire.net.utils.InfluxDbUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
 * @author bai
 */
@Configuration
public class InfluxDbConfig {

    @Value("${spring.influx.url:''}")
    private String influxDBUrl;

    @Value("${spring.influx.user:''}")
    private String userName;

    @Value("${spring.influx.password:''}")
    private String password;

    @Value("${spring.influx.database:''}")
    private String database;

    @Bean
    public InfluxDbUtils influxDbUtils() {
        return new InfluxDbUtils(userName, password, influxDBUrl, database, "");
    }
}

package com.tire.net.utils;
import lombok.Data;
import org.influxdb.InfluxDB;
import org.influxdb.InfluxDBFactory;
import org.influxdb.dto.Query;

/**
 * @author bai
 */
@Data
 public class InfluxDbUtils {
    private String userName;
    private String password;
    private String url;
    public String database;
    private String retentionPolicy;
    /**
     * InfluxDB实例
     */
    private InfluxDB influxDB;
    public InfluxDbUtils(String userName, String password, String url, String database,
                         String retentionPolicy) {
        this.userName = userName;
        this.password = password;
        this.url = url;
        this.database = database;
        this.retentionPolicy = retentionPolicy == null || "".equals(retentionPolicy) ? "autogen" : retentionPolicy;
        this.influxDB = influxDbBuild();
    }

    /**
     * 连接数据库 ，若不存在则创建
     *
     * @return influxDb实例
     */
    private InfluxDB influxDbBuild() {
        if (influxDB == null) {
            influxDB = InfluxDBFactory.connect(url, userName, password);
        }
        try {
            createDB(database);
            influxDB.setDatabase(database);
        } catch (Exception e) {
        } finally {
            influxDB.setRetentionPolicy(retentionPolicy);
        }
        influxDB.setLogLevel(InfluxDB.LogLevel.BASIC);
        return influxDB;
    }

    /****
     *  创建数据库
     * @param database
     */
    private void createDB(String database) {
        influxDB.query(new Query("CREATE DATABASE " + database));
    }

 }
