About the failure of the query method-----query(@Nonnull String var1, @Nonnull Class<M> var2)

The issue:
There is a problem with the data when using this method-----client.getQueryApi().query(statFlux.toString(), Stat.class);
However, when using this method, the data is obtained normally-----client.getQueryApi().query(statFlux.toString());
This indicates that the database is working correctly, but there may be problems converting the data.
The following is the relevant information.
The dependency:

        <spring-boot.version>3.1.0</spring-boot.version>
        <java.version>17</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <dependency>

        </dependency>

The model:

import com.influxdb.annotations.Column;
import com.influxdb.annotations.Measurement;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.time.Instant;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Measurement(name = "Stat")//influxDB注解
public class Stat {
    @Column
    private String intr;
    @Column
    private long ctxt;
    @Column
    private long btime;
    @Column
    private long processes;
    @Column
    private long procs_running;
    @Column
    private String procs_blocked;
    @Column
    private long softirq;
    @Column(timestamp = true)
    Instant time;
}

The code:

import com.cabin.empty.influxDB.Stat;
import com.cabin.influxDB.util.InfluxDBTemplate;
import com.cabin.utils.dateUtil.DateUtil;
import com.influxdb.client.InfluxDBClient;
import com.influxdb.query.FluxTable;

import org.springframework.boot.test.context.SpringBootTest;

import java.time.Duration;
import java.time.Instant;
import java.util.List;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class InfluxDBTest {
    @Resource(name = "influxByToken")
    private InfluxDBClient client;
    @Resource(name = "InfluxDBTemplate")
    private InfluxDBTemplate template;

    @Test
    void testAPI() {
        String bucket = "bucket";
        String measurement = "Stat";
        Instant stop = DateUtil.getNowInstant();
        Instant start = stop.minus(Duration.ofSeconds(1));

        Flux statFlux = Flux.from(bucket)
                .range(start, stop)
                .filter(Restrictions.and(
                        Restrictions.measurement().equal(measurement)));

        List<Stat> queryList = client.getQueryApi().query(statFlux.toString(), Stat.class);
        queryList.forEach(l -> {
            System.out.println(l.toString());
        });

        List<FluxTable> query = client.getQueryApi().query(statFlux.toString());
        query.forEach(l -> {
            l.getRecords()
                    .forEach(r -> System.out.println(r.getTime() + ": " + r.getValueByKey("_value")));
        });
    }

}

The result:

The information:

Commencez par QueryApi.query(String, Class) et comparez son comportement avec query(String), en utilisant le modèle Stat et la requête Flux fournis pour reproduire le résultat du mapping. C’est terminé lorsque la requête basée sur la classe renvoie les valeurs de champ renseignées affichées par les enregistrements FluxTable bruts.
