Question

          @Entity      
            public class Sinav{

                 @Column(name="sinav_adi",nullable=false)
                 private String sinavAdi;

                 @ManyToOne(fetch = FetchType.EAGER)
                 @JoinColumn(name="ogretmen_id")
                 private Kullanici ogretmenId;

                }//Class Sınav

第2类：

  @Entity
    public class Kullanici{

       @Column(name="tc_no")
        private String tcNo;

      @OneToMany(cascade = CascadeType.ALL,fetch = FetchType.EAGER,mappedBy = "role")
      private Set<KullaniciToRole> kullaniciToRole;

    }//Class Kullanici

第3类：

       @Entity
        public class KullaniciToRole {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="ktr_id")
private long ktrId;


@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name="kullanici_id")
private Kullanici kullanici;




        }//Class KullaniciToRole

第4类：

 @Entity
    public class Role {

        @ManyToMany(cascade = CascadeType.ALL,mappedBy = "kullanici",fetch =FetchType.EAGER)
        private Set<KullaniciToRole> kullanicilar;

    }//Class-Role

响应输出错误：

{
  "sinavAdi": "Mobil Android Uygulama",
  "ogretmenId": 
  {
    "tcNo": "45689782154",
      "kullaniciToRole":[{"ktrId":1,"kullanici":
  }
}

我对休眠中的类进行了映射。我使用了关系数据库设计。使用restfull jackson软件包完成此操作后，Web服务就会出现问题输出。您遇到“设置”问题。

我看到的最新JSON输出不完整，并且输出不正确，错误在哪里我该怎么办
