spring data 를 지원하지 않지만. springboot 2.x 에서 influx DB 를 자동으로 구성할수 있게 되어 있기때문에 구성정보만 입력해주면 된다.

org.springframework.boot.autoconfigure.influx.InfluxDbProperties 를 찾아보면 구체적 방법알수 있다.

서비스 클래스 작성

@Service
@AllArgsConstructor
@Slf4j
public class Monitor {

    private InfluxDB influxDB;

    @Scheduled(fixedRate = 5000)
    public void writeQPS() {
        // 가상  report 데이터 
        int count = (int) (Math.random() * 100);

        Point point = Point.measurement("ApiQPS")     // ApiQPS 테이블
                .tag("url", "/hello")  // url
                .addField("count", count)        // 통계
                .time(System.currentTimeMillis(), TimeUnit.MILLISECONDS)  // 时间
                .build();

        // test database 에 저장
        influxDB.write("test", "autogen", point);

        log.info("총 건수：" + count);
    }

}
