我以前也问过类似的问题，但还是没有答案。这是我的代码和日志。

package com.yunus.ccApp.entities;

import javax.persistence.*;
import java.io.Serializable;

@Entity
@Table(name = "URUNLER")
public class UrunEntity implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "URUN_ID")
    private int urunId;

    @Column(name = "DOGUM_AGIRLIGI")
    private Double dogumAgirligi;

    @Column(name = "DOGUM_SEKLI")
    private String dogumSekli;

    @Column(name = "DOGUM_TARIHI")
    private String dogumTarihi;

    @Column(name = "HAYVAN_ADI")
    private String hayvanAdi;

    @Column(name = "HAYVAN_ANNE_ADI")
    private String hayvanAnneAdi;

    @Column(name = "HAYVAN_CINSIYET")
    private String hayvanCinsiyet;

    @Column(name = "HAYVAN_IRKI")
    private String hayvanIrki;

    @Column(name = "HAYVAN_KUPE_NO")
    private int hayvanKupeNo;

    @Column(name = "HAYVAN_RESMI")
    private String hayvanResmi;

    @Column(name = "SUT_MIKTARI")
    private Double sutMiktari;

    @Column(name = "SUT_TARIHI")
    private String sutTarihi;

    @Column(name = "TOHUMA_HAZIR")
    private Boolean tohumaHazir;

    @Column(name = "URUN_TUTAR")
    private Double urunTutar;

    @Column(name = "USER_ID")
    private Integer userId;

   //getter and setters

这是我的错误代码。我研究了那么多，但什么也找不到。他们说是关于关键敏感度，但我不这么认为。因为我什么都试过了。
当我试图发送一个get post时，每次在每个查询中都会遇到这个错误。请帮帮我。
