javax.persistence Annotations on field, getter or setter?

Question

I am currently learning Hibernate and the Java Persistence API.

I have an @Entity class, and need to apply annotations to the various fields. I have included in the code

Answer 1

You have to put annotations only for field or only for getter

@Id 
@Column(name="id", unique=true, nullable=false)
private int    id;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

or

private int    id;

@Id 
@Column(name="id", unique=true, nullable=false)
public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

And for all fields/properties in same way. All annotations for fields or all annotations for getter
