我正在尝试联接2个表（ManytoMany），但遇到以下错误：
导致错误：org. hib.引用com.MD.Medicine.Models.计划的com.MD.Medicine.Models.Meds.assignedMeds的referencedColumnNames（计划日期、计划Id、工作日）未Map到单个属性
我的实体，Plans.java:

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "plans")
@EqualsAndHashCode(exclude = "assignedMeds")
public class Plans {
    @EmbeddedId
    private PlansPKId plansPKId;

    @Column
    private String planName;

    @Column
    private String weekday;

    @ManyToMany
    @JoinTable(name = "Plan_Meds", joinColumns = {
            @JoinColumn(name = "planDate", referencedColumnName = "planDate"),
            @JoinColumn(name = "planId", referencedColumnName = "planId"),
            @JoinColumn(name = "weekday", referencedColumnName = "weekday"), }, inverseJoinColumns = @JoinColumn(name = "id"))
    private Set<Meds> assignedMeds = new HashSet<>();

}

PlansPKId.java (for计划模型）：

@Data
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode
@Embeddable
public class PlansPKId implements Serializable {

    private Date planDate; // format: yyyy-mm-dd
    private long planId;

  

}

Meds.java:

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "meds")

public class Meds {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column
    private String name;

    @Column
    private BigDecimal price;

    @Column
    private String category;

    @Column
    private int pillNumber;

    @Column
    private Date date;

    @JsonIgnore
    @ManyToMany(mappedBy = "assignedMeds")
    private Set<Plans> plans = new HashSet<>();

}

当我只加入这个：

@ManyToMany
    @JoinTable(name = "Plan_Meds", joinColumns = {
            @JoinColumn(name = "planDate", referencedColumnName = "planDate"),
            @JoinColumn(name = "planId", referencedColumnName = "planId"), }, 
            inverseJoinColumns = @JoinColumn(name = "id"))
    private Set<Meds> assignedMeds = new HashSet<>();

它工作正常，但是如果我有“工作日”一栏，我就开始得到错误。我不应该这样加入他们吗？
