方法详细资料

convertToDatabaseColumn

public String convertToDatabaseColumn(T attribute)

Converts the value stored in the entity attribute into the data representation to be stored in the database.

指定者:

convertToDatabaseColumn 在接口中 javax.persistence.AttributeConverter<T,String>

参数:

attribute - the entity attribute value to be converted

the converted data to be stored in the database column

convertToEntityAttribute

public T convertToEntityAttribute(String dbData)

Converts the data stored in the database column into the value to be stored in the entity attribute. Note that it is the responsibility of the converter writer to specify the correct dbData type for the corresponding column for use by the JDBC driver: i.e., persistence providers are not expected to do such type conversion.

参数:

dbData - the data from the database column to be converted

返回:

the converted value to be stored in the entity attribute
