更新時(shí)間：2025年12月23日 10:40:47 作者：moxiaoran5753

本文主要介紹了Springboot整合IoTB的實(shí)現(xiàn)示例,文中通過示例代碼介紹的非常詳細(xì),對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

一、引入依賴

 <!--引入iotdb session依賴-->
<dependency>
	<groupId>org.apache.iotdb</groupId>
	<artifactId>iotdb-session</artifactId>
	<version>1.3.2</version>
</dependency>

二、配置IotDB連接

iotdb:
  username: root
  password: root
  ip: 192.168.56.10
  port: 6667
  #批量操作數(shù)量
  maxSize: 200

三、創(chuàng)建配置類

import lombok.extern.slf4j.Slf4j;
import org.apache.iotdb.session.pool.SessionPool;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
@Slf4j
public class IotDBSessionConf {

    @Value("${iotdb.username}")
    private String username;

    @Value("${iotdb.password}")
    private String password;

    @Value("${iotdb.ip}")
    private String ip;

    @Value("${iotdb.port}")
    private int port;

    @Value("${iotdb.maxSize}")
    private int maxSize;

    //Session線程池
    private static SessionPool pool;

    @Bean
    public SessionPool initSessionPool() {

        if(pool==null) {

            log.info(">>>>>SessionPool初始化....");

            pool =
            new SessionPool.Builder()
                    .user(username)
                    .password(password)
                    .host(ip)
                    .port(port)
                    .maxSize(maxSize)
                    .build();
        }


        return pool;

    }
}

四、創(chuàng)建service和實(shí)現(xiàn)類

@Service
@RequiredArgsConstructor
public class IoTDBServiceImpl implements IoTDBService {

    private final IotDBSessionConf conf;

    @Override
    public SessionDataSetWrapper executeQueryStatement(String sql) {
        SessionPool sessionPool = conf.initSessionPool();
        SessionDataSetWrapper wrapper = null;
        try {
            wrapper = sessionPool.executeQueryStatement(sql);
        } catch (IoTDBConnectionException e) {
            throw new RuntimeException(e);
        } catch (StatementExecutionException e) {
            throw new RuntimeException(e);
        }
        return wrapper;
    }

    @Override
    public SessionDataSetWrapper executeRawDataQuery(List<String> path, long startTime, long endTime, long timeOut) {
        SessionPool sessionPool = conf.initSessionPool();
        SessionDataSetWrapper wrapper = null;
        try {
            wrapper = sessionPool.executeRawDataQuery(path, startTime, endTime, timeOut);
        } catch (IoTDBConnectionException e) {
            throw new RuntimeException(e);
        } catch (StatementExecutionException e) {
            throw new RuntimeException(e);
        }
        return wrapper;
    }
}

五、創(chuàng)建工具類

@RequiredArgsConstructor
public class IoTDBUtils {

    private final IoTDBService iotDBService;

    /**
     * 根據(jù)自定義SQL語句執(zhí)行查詢
     * @param sql
     * @return
     */
    SessionDataSetWrapper executeQueryStatement(String sql) {
        return iotDBService.executeQueryStatement(sql);
    }

    /**
     * 根據(jù)時(shí)間區(qū)間執(zhí)行查詢數(shù)據(jù)
     * @param paths 時(shí)間序列
     * @param startTime 開始時(shí)間戳（包含）
     * @param endTime 結(jié)束時(shí)間戳(不包含)
     * @param timeOut 超時(shí)時(shí)間
     * @return
     */
    SessionDataSetWrapper executeRawDataQuery(List<String> paths, long startTime, long endTime, long timeOut){
        return iotDBService.executeRawDataQuery(paths, startTime, endTime, timeOut);
    }
}

單元測試

@SpringBootTest(classes = IotDBSessionConfTest.class)
public class IotDBSessionConfTest {

    // 測試連接
    @Test
    public void testInitSessionPool() {
        IotDBSessionConf conf = new IotDBSessionConf();
        SessionPool sessionPool = conf.initSessionPool();
        System.out.println(sessionPool.getVersion());
    }
}
