要将IoTDB查询结果集转换为Java对象，您需要编写Java代码以解析查询结果并将其转换为相应的Java对象。

以下是一个示例代码，可以将IoTDB查询结果集转换为Java对象：

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;import org.apache.iotdb.tsfile.file.metadata.enums.TSDataType;
import org.apache.iotdb.tsfile.read.common.Field;
import org.apache.iotdb.tsfile.read.common.RowRecord;
import org.apache.iotdb.tsfile.read.common.TimeRange;
import org.apache.iotdb.tsfile.read.filter.basicfilters.PointFilter;
import org.apache.iotdb.tsfile.read.filter.factory.FilterFactory;
import org.apache.iotdb.tsfile.read.reader.TsFileInputDescriptor;
import org.apache.iotdb.tsfile.read.reader.TsFilePageReader;
import org.apache.iotdb.tsfile.utils.Binary;public class IoTDBToJavaObject {public static void main(String[] args) throws IOException {String filePath = "path/to/your/tsfile";TsFileInputDescriptor inputDescriptor = new TsFileInputDescriptor(filePath);TsFilePageReader reader = new TsFilePageReader(inputDescriptor);// Create a filter to select data for the desired device and sensorFilterFactory factory = FilterFactory.instance();PointFilter deviceFilter = factory.deviceFilter("device-id");PointFilter sensorFilter = factory.sensorFilter("sensor-id");PointFilter filter = factory.and(deviceFilter, sensorFilter);// Read the data and convert it to Java objectsList<MyJavaObject> javaObjects = new ArrayList<>();while (reader.hasNext()) {RowRecord rowRecord = reader.next();TimeRange timeRange = rowRecord.getTimeRange();TSDataType dataType = rowRecord.getFields()[1].getDataType();double value = rowRecord.getFields()[1].getBinaryStream().readDouble();MyJavaObject javaObject = new MyJavaObject(timeRange, dataType, value);javaObjects.add(javaObject);}reader.close();// Print the Java objectsfor (MyJavaObject javaObject : javaObjects) {System.out.println(javaObject);}}
}
