从接口复制的说明: TypeConverter

This method allows retrieving a column value as an instance of a different class than the default Java class that the column's JDBCType maps to.

This implements the aspect of the JDBC spec that specifies multiple JDBCTypes on which a ResultSet getter method may be called.

指定者:

convert 在接口中 TypeConverter

类型参数:

T - Type of the Java Class

参数:

value - Column value

clazz - Instance of the Class to which the value needs to be converted

conversionParams - Optional conversion parameters to use in the conversion

返回:

Column value as an instance of type T

抛出:

SQLException - if the conversion is not supported or the conversion operation fails.
