org.hibernate.AnnotationException: No identifier specified for entity

When I was working with hibernate project. I got this exception. Actually, the issue was because of missing @Id from one of my entity class. @Id is used on the primary key field in the entity class. The field is a primary key in your database table.

If you do not have any primary key in your database table then you can use rowId as the primary key for your entity class.

@Column(name = "ROWID", insertable = false, updatable = false)
private String rowId;
