Question

我有一个名为MatchStats的实体，我想检索一个matchstats列表，其中在“下注者”列表中有一个用户名为“ somthing” /punter.player.userName=“ something”的下注者。这是组成matchstats的以下三个实体

   public class MatchStats extends DefaultEntity {

    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    private List<Punter> punters;


    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    private List<Punter> winners;

    private double winning_amount; 

}

打孔实体

 @Entity
@Table(name = "Punter")
public class Punter extends DefaultEntity {


    @Valid
    @ManyToOne(targetEntity = User.class)
    @JoinColumn(name="player")
    private User player;

    @NotBlank
    private double risk;

}

用户实体

    @Entity
@Table(name = "Users")
public class User extends DefaultEntity {


    @Column(name = "FirstName")
    @NotNull(message = "Enter a FirstName")
    private String firstName;


    @Column(name = "LastName")
    @NotBlank(message = "Enter a LastName")
    private String lastName;


    @Column(unique = true,name = "UserName")
    @NotBlank(message = "Enter a UserName")
    private String userName;
}

我希望springJpa会有这样的东西

Page<MatchStats> getAllByPuntersPlayer(User user, Pageable pageable);

但是我认为这是不可能的，有没有办法实现这一目标？
