com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '2' for key 'PRIMARY' during Testing

Hi I have this test class which saves 3 entity class to database.

@Test
//    @Transactional
public void test() throws ParseException {
    //Creating a movie
    Movie movie1 = new Movie();
    movie1.setMovieName("Movie One");
    movie1.setPlot("Sample Plot1");
    movie1.setReleaseDate(new Date(DateUtils.dateToMilliSecondsConverter(20160101L)));
    //Creating cast
    Cast cast1 = new Cast("male", "lead", Type.MALE_LEAD);
    Cast cast2 = new Cast("female", "lead", Type.FEMALE_LEAD);
    List<Cast> cast = new ArrayList<>();
    cast.add(cast1);
    cast.add(cast2);
    //adding cast to movie
    movie1.setCast(cast);
    movie1.setRuntime(120);
    movieDAO.saveOrUpdate(
    //Creating a movie
    Movie movie2 = new Movie();
    movie2.setMovieName("Movie Two");
    movie2.setPlot("Sample Plot2");
    movie2.setReleaseDate(new Date(DateUtils.dateToMilliSecondsConverter(20160101L)));
    movie2.setRuntime(120);
    movieDAO.saveOrUpdate(movie2);
    CinemaHall ch = new CinemaHall();
    ch.setName("Odeon");
    ch.setMovie(new ArrayList<Movie>() {
    {
        add(movie1);
        add(movie2);
    }
    });
    cinemaHallDAO.saveOrUpdate(ch);

}

Entity Class are as follows

CinemaHall.java

public class CinemaHall{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    private String name;
    @OneToMany(targetEntity = Movie.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<Movie> movie = new ArrayList<>();
}

Movie.Java

public class Movie implements Common {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    private String movieName;
    private Date releaseDate;
    @OneToMany(targetEntity = Cast.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<Cast> Cast = new ArrayList<>();
    private String plot;
    private Integer runtime;
    @ElementCollection(targetClass = String.class)
    private List<String> showTimings = new ArrayList<>();
}

Cast.Java

public class Cast{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    private String firstName;
    private String lastName;
    @Enumerated(value = EnumType.STRING)
    private Type type;
}

I get the below error when I run the above mentioned test.
