有没有办法让ORMLite自动生成对象的创建日期？

I've implemented a date myself using long and I know I can persist the date in a few different ways:

如果我理解这个问题，ORMLite 确实支持使用自定义数据类型持久化器。请参阅有关该主题的文档:

引用:

ORMLite has internal definitions for storing the basic primitive and other common data types. See section Persisted Data Types. Sometimes, however, you either want to store a new data type in your database or you want to change the way ORMLite stores values to the database for common types – this often happens when you are trying to work with an existing schema. You can change how types are stored in the database by defining a class which implements the DataPersister interface.

那里有一些例子。
