原因：com.datastax.driver.core.exceptions.InvalidQueryException：日期 (13) 的预期长度为 8 或 0 字节

Question

我正在尝试使用 spring-data-cassandra 插入数据。但是当我的应用程序是运行 SpringBoot（版本是 1.5.3）

时，我收到以下错误

我在spring-data中添加了一个实现CrudResposity的自定义CallHistoriyRespority对象，并使用save方法插入数据对象

我找不到任何原因，这个问题让我很困惑

cassandra table 描述如下：

CREATE TABLE userdevices.callhistorylogs (
userid bigint,
deviceid text,
serialnumber timestamp,
objectid text,
dialtime timestamp,
dialtype int,
duration int,
phone text,
simid int,
targetphone text,
PRIMARY KEY ((userid, deviceid), serialnumber, objectid)

我的 java 配置如下：

@Table("callhistorylogs")
public class CallHistoryLogPO{
 @PrimaryKeyColumn(ordinal = 0 ,type = PrimaryKeyType.PARTITIONED)
 private Long userID;

 @PrimaryKeyColumn(ordinal = 1,type = PrimaryKeyType.PARTITIONED)
 private String deviceID;

 @PrimaryKeyColumn(ordinal = 2,type = PrimaryKeyType.CLUSTERED)
 private String serialNumber;

 @PrimaryKeyColumn(ordinal = 3,type = PrimaryKeyType.CLUSTERED)
 private String objectID;

 private Date dialTime;

 private Call.DialType dialType;

 private Integer duration;

 private String phone;

 private Integer simID;

 private String targetPhone;
 .....
}

保存方法如下：

    CallHistoriesPO callHistories = new CallHistoriesPO();
    callHistories.setUserID(20170627L);
    callHistories.setDeviceID("160129999");
    callHistories.setPhone("17681879236");
    ......
    callHistoryResposity.save(callHistories);

Answer 1

serialNumber 是 cassandra 中映射到 java.util.Date 的时间戳，而您使用 String 表示 serialNumber。

cql-to-java-type-mapping
