android – GreenDAO – 多列上的主键

GreenDAO是否支持多列的主键？

我在两列上使用Property的方法primaryKey()但它不起作用.我得到例外：

Caused by: android.database.sqlite.SQLiteException: table “table” has
more than one primary key

如何在多列上创建主键？我应该编辑生成的DAO类吗？

解决方法:

documentation说：

Currently, entities must have a long or Long property as their primary key.

To work around this issue, you can use a long primary key and use an unique index for the intended “key” properties.
