我在我的模型中使用过BigeDecimal [1]。由于在mysql中无法实现精度和比例，我尝试使用 CustomUsertype 实现[2]。
现在mysql表将列类型更改为double。
但是当我尝试存储我的实体时，hibernate无法重新调整值并抛出错误
Caused by: java.sql.SQLException: No value specified for parameter 1
我如何克服这个问题？

实现此目的的另一种可能性是使用@Convert注释。以下是我如何使用BigDecimal和double执行此操作的示例。我没有测试它，但它应该做的伎俩。当数据库中有不同的表示时，我通常会为枚举编写转换器。
public class BigDecimalConverter implements AttributeConverter<BigDecimal, double> {
@Override
public double convertToDatabaseColumn(BigDecimal bigDecimalValue) {
if(bigDecimalValue == null) {
return null;
}
return bigDecimalValue.doubleValue();
}
@Override
public BigDecimal convertToEntityAttribute(double doubleValue) {
if(doubleValue == null) {
return null;
}
return BigDecimal.valueOf(doubleValue);
}
}
