@DynamicInsert @DynamicUpdate does not work?

I am using Hibernate 4. When I use

    @org.hibernate.annotations.Entity(dynamicInsert = true, dynamicUpdate = true,
 selectBeforeUpdate = true)

it works.

But, I found that they have deprecated, so I follow the instructions to use the @DynamicInsert and @DynamicUpdate, like this:

@Entity
@DynamicInsert
@DynamicUpdate
@SelectBeforeUpdate 
@Table(name = "User")
public class User {
       ..........
}

It does not work.

How do I use @DynamicInsert and @DynamicUpdate ?
