Once we have identified the class being identified and its mapping table, we need to specify the identity property of the class and its corresponding identity column in the mapping table.
我们已经标识了类和类对应的映射表，接下来我们需要标识类的标识属性和映射表中的标识列。
Identity properties pertain to identity columns, which guarantee the uniqueness of the row to which the identity column belongs.
标识属性是标识列固有的，用于确保标识列所属的行的唯一性。
