        从接口复制的说明: Type
        During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.
        指定者:
        replace 在接口中 Type

        从接口复制的说明: Type
        Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

        This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

        指定者:
        isEqual 在接口中 Type
        覆盖:
        isEqual 在类中 AbstractType
        参数:
        x - The first value

        getHashCode 在接口中 Type
        覆盖:
        getHashCode 在类中 AbstractType

        getColumnSpan 在接口中 Type
        参数:
        mapping - The mapping object :/
        返回:
        The number of columns

        从接口复制的说明: Type

        指定者:
        nullSafeGet 在接口中 Type
        参数:
        rs - The result set from which to extract value.

        从接口复制的说明: Type
        Bind a value represented by an instance of the mapped class to the JDBC prepared statement, ignoring some columns as dictated by the 'settable' parameter. Implementors should handle the possibility of null values. A multi-column type should bind parameters starting from index.

        参数:
        st - The JDBC prepared statement to which to bind
