Two different positions for the JPA annotations

Question

I am working on JPA and JSF.

I found two ways to put the annotation:

1. Above the instance variable.

public class Project implements Serializable {
    @ID
    @NotNull
    private Long idProject
    public Long getIdProject() {
        return this.idProject
    }
}

2. Above getter

public class Project implements Serializable {
    private Long idProject
    @ID
    @NotNull
    public Long getIdProject() {
        return this.idProject}
    }

What is the difference? What is the best to use?

There is not best to use. Both are supported so that you can do what you want. — Sotirios Delimanolis, Oct 03 '13 at 13:58
Because people (including myself) deemed that you won't be able to get an objective answer. It's too much based on opinion. — Sotirios Delimanolis, Oct 03 '13 at 17:14

Like Sotirios said, both are supported but I much prefer putting the Annotations on the variable. The getters and setters are usually at the end of the class (at least that's where "I" think they belong). If you don't Annotate at the variable then you leave the maintainer to go search and make sure you wired it in "somewhere". I haven't heard a good reason why you would put it on the setter method.
