JPA - SQLException 创建记录

Question

我已经从数据库中导入了这个实体类（使用 Netbeans 函数 - 来自数据库的实体类）。

不幸的是，我无法让它工作。

IMS_MEASUREMENTS 表

INSTALLED_IMS_ID - NUMBER(9)
MEASUREMENT_IMS_ORD - NUMBER(9)
MEASUREMENT_TYPE_ID - NUMBER(9)
DEVICE_ID - NUMBER(9)
MEASUREMENT_TIME - TIMESTAMP(3)
MEASUREMENT_VALUE - NUMBER(9,2)
MEASUREMENT_MAX_VALUE - NUMBER(9,2)
MEASUREMENT_MIN_VALUE - NUMBER(9,2)
NOTES - VARCHAR(255 BYTE)
PREVIOUS_INFO - NUMBER(5)
LAST_UPDATE - TIMESTAMP(3)
MEASUREMENT_PRECISION - NUMBER(2)
LOCALIZATION_ID - NUMBER(9) 

主键是 (INSTALLED_IMS_ID, MEASUREMENT_IMS_ORD)

ImsMeasurements.java

@Entity
public class ImsMeasurements implements Serializable {
    @EmbeddedId
    protected ImsMeasurementsPK imsMeasurementsPK;

    @Column(name = "MEASUREMENT_TYPE_ID")
    private Integer measurementTypeId;
    @Basic(optional = false)
    @Column(name = "MEASUREMENT_TIME")
    @Temporal(TemporalType.TIMESTAMP)
    private Date measurementTime;
    @Column(name = "MEASUREMENT_VALUE")
    private BigDecimal measurementValue;
    @Column(name = "MEASUREMENT_MAX_VALUE")
    private BigDecimal measurementMaxValue;
    @Column(name = "MEASUREMENT_MIN_VALUE")
    private BigDecimal measurementMinValue;
    @Column(name = "NOTES")
    private String notes;
    @Column(name = "PREVIOUS_INFO")
    private Integer previousInfo;
    @Column(name = "LAST_UPDATE")
    @Temporal(TemporalType.TIMESTAMP)
    private Date lastUpdate;
    @Column(name = "MEASUREMENT_PRECISION")
    private Short measurementPrecision;
    @Column(name = "LOCALIZATION_ID")
    private Integer localizationId;
    ....
    ....

    //constructors
    public ImsMeasurements() {
    }

    public ImsMeasurements(ImsMeasurementsPK imsMeasurementsPK) {
        this.imsMeasurementsPK = imsMeasurementsPK;
    }

    public ImsMeasurements(ImsMeasurementsPK imsMeasurementsPK, Date measurementTime) {
        this.imsMeasurementsPK = imsMeasurementsPK;
        this.measurementTime = measurementTime;
    }

    public ImsMeasurements(int installedImsId, int measurementImsOrd) {
        this.imsMeasurementsPK = new ImsMeasurementsPK(installedImsId, measurementImsOrd);
    }
}

ImsMeasurementsPK.java

@Embeddable
public class ImsMeasurementsPK implements Serializable {
    @Basic(optional = false)
    @Column(name = "INSTALLED_IMS_ID")
    private int installedImsId;

    @Basic(optional = false)
    @Column(name = "MEASUREMENT_IMS_ORD")
    private int measurementImsOrd;
    ....

    //constructors
    public ImsMeasurementsPK() {
    }

    public ImsMeasurementsPK(int installedImsId, int measurementImsOrd) {
        this.installedImsId = installedImsId;
        this.measurementImsOrd = measurementImsOrd;
    }
}

设置测量。

//setting measure primary key    
ImsMeasurements mis = new ImsMeasurements(new ImsMeasurementsPK(1, 1));
....

坚持。

em.persist(mis);

我发现这种 java.sql.SQLException: ORA-01438: value greater than specified precision allowed for this column

org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.2.0.v20110202-r8913): org.eclipse.persistence.exceptions.DatabaseException

JPA 提供者 -> EclipseLink，版本：Eclipse Persistence Services - 2.2.0.v20110202-r8913

我尝试插入的值：

mis.setMeasurementValue(BigDecimal.valueOf(110));
mis.setMeasurementTypeId(10);
String s = "2014-04-17 12:05:00";
Date date = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.ITALY).parse(s);
mis.setMeasurementTime(date);
mis.setMeasurementPrecision(Short.MIN_VALUE);
mis.setMeasurementMinValue(BigDecimal.ZERO);
mis.setMeasurementMaxValue(BigDecimal.ZERO);
mis.setLocalizationId(Integer.valueOf(10));
mis.setDeviceId(2);
mis.setImsSystems(110);    

问题出在哪里，我错在哪里？

有三个字段使用“BigDecimal”类型，可能会变大。您需要检查 db 中每一列的类型。
