JSONMANAGED参考

Question

我正在尝试在我的一个实体类中使用json强制引用。该实体与另一个具有复合主键的实体具有多对多关系。

我在A类中

 /**
     * @return the classB
     */
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SEC_ID", referencedColumnName = "PT_ID", updatable = false, insertable = false)
    @JsonBackReference
    public classB getClassB() {
        return classB;
    }

ClassB

/**
 * @return the pxxId
 */
@EmbeddedId
public PxxId getPxxId() {
    return pxxId;
}

嵌入式ID

@Embeddable
public class PxxId implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 7080557675086058087L;
    private Long taId;
    private Long maId;

    /**
     * @return the id
     */
    @Column(name = "PT_ID", nullable = false, length = 20)
    public Long getTaId() {
        return tabId;
    }

    /**
     * @param id
     *            the id to set
     */
    public void setTaId(Long id) {
        this.taId = id;
    }

    /**
     * @return the maId
     */
    @Column(name = "MA_ID", length = 20, nullable = false)
    public Long getMaId() {
        return maId;
    }

    /**
     * @param mId
     *            the maId to set
     */
    public void setMaId(Long maId) {
        this.maId = maId;
    }
}

我尝试了上述操作，但出现类似

的错误
