Java JPA-SQLException创建记录

我已经从数据库中导入了这个实体类（使用数据库中的Netbeans函数-实体类）

不幸的是，我不能让它工作

IMS\U测量表

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（已安装的IMS\U ID、测量IMS\U ORD）

ImsMeasurements.java

        this.installedImsId = installedImsId;
        this.measurementImsOrd = measurementImsOrd;
    }
}

设置测量值

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

坚持下去

em.persist(mis);

我发现这种java.sql.SQLException:ORA-01438:值大于此列允许的指定精度

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：EclipsePersistenceServices-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

提前感谢,，

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

对象中有一个值

ImsMeasurements

比表中指定的列长。这是一个可行的解决方案，谢谢。您可以找出[13个参数绑定]是什么吗？添加值和ddl。我认为问题出在从bin ImsMeasurementsPK到DB上的主复合键的映射上，但我不理解原因。映射是使用Netbeans函数（“从类创建实体”）从JPA自动生成的。我不知道Netbeans，所以我无法在这方面帮助您。谢谢！我以您可以观察从JPA自动生成的DB数据类型和相对类型的方式编辑问题。有什么奇怪的吗？有些不一致？似乎测量精度-数字（2）有问题。它的长度仅为2，但您已使用Short.MIN_值设置了一个值，即-32768，其长度为5。
