1、maven依赖

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

2、配置文件

iotdb:
  server:
    url: localhost
    port: 6667
    name: root
    pwd: root
    maxSize: 100
    dataBaseName: root.ln

3、定义配置文件

@Data
@Component("IotDbProperties")
@Configuration
public class IotDbProperties {
    @Value("${iotdb.server.url}")
    private String url;
    @Value("${iotdb.server.port}")
    private Integer port;
    @Value("${iotdb.server.name}")
    private String name;
    @Value("${iotdb.server.pwd}")
    private String pwd;
    @Value("${iotdb.server.maxSize}")
    private Integer maxSize;
    @Value("${iotdb.server.dataBaseName}")
    private String iotDataBaseName;

    @Bean("sessionPool")
    public ISessionPool getSessionPool() {
        return new SessionPool(this.url, this.port, this.name, this.pwd, this.maxSize);
    }
}

4、在服务层使用

通过sessionPool直接调用方法

@Service
@Slf4j
public class IotDbServiceImpl implements IIotDbService {

    @Resource
    private ISessionPool sessionPool;

    @Value("${iotdb.server.dataBaseName}")
    private String iotDataBaseName;

注意：如果需要用到：SessionDataSetWrapper sessionDataSetWrapper查询的话，则必须调用

sessionDataSetWrapper.close();

或者使用 try-with-resources会进行自动关闭
