我們一直在使用Play 2.3.9，現在我們正在遷移到Play 2.4.1當我使用舊版本的玩保存一個實體的作品，但與新的版本Id不會生成。Migration 2.4後，使用現有的postgresdb序列生成Play-2.4實體的ID
如果我使用，
@GeneratedValue(strategy = GenerationType.SEQUENCE)
它的正常工作，但是當我使用，
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
得到以下異常
[error] p.c.s.n.PlayDefaultUpstreamHandler - Cannot invoke the action
