Though ROWID is a pseudo-column,yet as ROWID corresponds to the physical address of a ROW, it is the quickest mean to retrieve any row data. As @Id is used to identify the object uniquely and ROWID is unique inside a table, we can exploit it to overcome the issue we are discussing about. Actually, if we don't need any meaningful unique identifier, ROWID is the best column to annotate with @Id annotation as it corresponds to the physical address of the row. The following code worked for me.
`
@Id
@Column(name = "ROWID")
private String Id;`
