vaadin/spring重复错误中的错误

Question

我有一个用户类和一个电影类，我想将其合并到单独的列表中。曾经看过看过的电影，一张用于监视列表。单独的一切都很好，但是看来，当我要将它们放在两个合并上时，即使它们保存在不同命名的列中，我也会遇到重复错误。

@ManyToMany(cascade = {CascadeType.MERGE}, fetch = FetchType.EAGER)
@JoinTable(name = "user_watch_list", joinColumns = @JoinColumn(name = "watche_User_ID", referencedColumnName = "id"), inverseJoinColumns = @JoinColumn(name = "watch_Movie_id",referencedColumnName = "movieID"))
private List<Movie> watchList = new ArrayList<>();

@ManyToMany(cascade = {CascadeType.MERGE}, fetch = FetchType.EAGER)
@JoinTable(name = "user_watched_movies", joinColumns = @JoinColumn(name = "watcheed_User_ID",referencedColumnName = "id"), inverseJoinColumns = @JoinColumn(name = "watched_movie_id",referencedColumnName = "movieID"))
private List<Movie> watchedMovies = new ArrayList<>();
