Hibernate Util Class

Question

Я пытаюсь переписать приложение java, которое у меня было, потому что я внес много изменений в базу данных. Я скопировал / вставил имеющийся у меня класс HibernateUtil в свое новое приложение. И это просто не работает :(.

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {
    private static ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();

    private static SessionFactory sessionFactory = null;
    static {
        sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
    }

    public static Session getSession() {

        Session session = null;
        if (threadLocal.get() == null) {
            // Create Session object
            session = sessionFactory.openSession();
            threadLocal.set(session);
        } else {
            session = threadLocal.get();
        }
        return session;
    }

    public static void closeSession() {
        Session session = null;
        if (threadLocal.get() != null) {
            session = threadLocal.get();
            session.close();
            threadLocal.remove();
        }
    }

    public static void closeSessionFactory() {
        sessionFactory.close();
    }
}

Это ошибка, которую я получаю:

Кроме того, я был бы очень признателен, если бы вы помогли мне создать свой собственный. Хотя СЕЙЧАС я просто хочу завершить sh свое приложение. Я много дней проработал, восстанавливая базу данных для новых требований, у меня почти весь код готов, и я застрял на этом: / плохо себя чувствую. Я уже проверял мой файл hibernate.cfg. xml и кажется нормальным!

Вот мой класс Entity:

package Entities;

import javax.persistence.*;
import java.math.BigDecimal;
import java.util.Objects;

@Entity
@Table(name = "user_is_worker", schema = "walker", catalog = "")
public class UserIsWorkerEntity {
    private String workerId;
    private String userLogName;
    private String userLogPass;
    private String amka;
    private String afm;
    private BigDecimal salary;
    private Byte bonusProgram;
    private UserEntity userByWorkerId;
    private UserIsWorkerEntity userIsWorkerBySupervisor;
    private PermisEntity permisByPermisId;

    @Id
    @Column(name = "WorkerID", nullable = false, length = 20)
    public String getWorkerId() {
        return workerId;
    }

    public void setWorkerId(String workerId) {
        this.workerId = workerId;
    }

    @Basic
    @Column(name = "UserLogName", nullable = true, length = 15)
    public String getUserLogName() {
        return userLogName;
    }

    public void setUserLogName(String userLogName) {
        this.userLogName = userLogName;
    }

    @Basic
    @Column(name = "UserLogPass", nullable = true, length = 15)
    public String getUserLogPass() {
        return userLogPass;
    }

    }

    @Basic
    @Column(name = "AMKA", nullable = true, length = 12)
    public String getAmka() {
        return amka;
    }

    public void setAmka(String amka) {
        this.amka = amka;
    }

    @Basic
    @Column(name = "AFM", nullable = true, length = 9)
    public String getAfm() {
        return afm;
    }

    public void setAfm(String afm) {
        this.afm = afm;
    }

    @Basic
    @Column(name = "Salary", nullable = true, precision = 2)
    public BigDecimal getSalary() {
        return salary;
    }

    public void setSalary(BigDecimal salary) {
        this.salary = salary;
    }

    @Basic
    @Column(name = "BonusProgram", nullable = true)
    public Byte getBonusProgram() {
        return bonusProgram;
    }

    public void setBonusProgram(Byte bonusProgram) {
        this.bonusProgram = bonusProgram;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        UserIsWorkerEntity that = (UserIsWorkerEntity) o;
        return Objects.equals(workerId, that.workerId) &&
                Objects.equals(userLogName, that.userLogName) &&
                Objects.equals(userLogPass, that.userLogPass) &&
                Objects.equals(amka, that.amka) &&
                Objects.equals(afm, that.afm) &&
                Objects.equals(salary, that.salary) &&
                Objects.equals(bonusProgram, that.bonusProgram);
    }

    @Override
    public int hashCode() {
        return Objects.hash(workerId, userLogName, userLogPass, amka, afm, salary, bonusProgram);
    }

    @OneToOne
    @JoinColumn(name = "WorkerID", referencedColumnName = "UserID", nullable = false)
    public UserEntity getUserByWorkerId() {
        return userByWorkerId;
    }

    public void setUserByWorkerId(UserEntity userByWorkerId) {
        this.userByWorkerId = userByWorkerId;
    }

    @ManyToOne
    @JoinColumn(name = "Supervisor", referencedColumnName = "WorkerID")
    public UserIsWorkerEntity getUserIsWorkerBySupervisor() {
        return userIsWorkerBySupervisor;
    }

    public void setUserIsWorkerBySupervisor(UserIsWorkerEntity userIsWorkerBySupervisor) {
        this.userIsWorkerBySupervisor = userIsWorkerBySupervisor;
    }

    @ManyToOne
    @JoinColumn(name = "PermisID", referencedColumnName = "PermisID")
    public PermisEntity getPermisByPermisId() {
        return permisByPermisId;
    }

    public void setPermisByPermisId(PermisEntity permisByPermisId) {
        this.permisByPermisId = permisByPermisId;
    }
}

А вот и Entity из таблицы, которая связана с предыдущей :

package Entities;

import javax.persistence.*;
import java.sql.Date;
import java.util.Objects;

@Entity
@Table(name = "user", schema = "walker", catalog = "")
public class UserEntity {
    private String userId;
    private String name;
    private String surname;
    private Date birthday;
    private UserIsShopkeeperEntity userIsShopkeeperByUserId;
    private UserIsWorkerEntity userIsWorkerByUserId;

    @Id
    @Column(name = "UserID", nullable = false, length = 20)
    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    @Basic
    @Column(name = "Name", nullable = true, length = 35)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Basic
    @Column(name = "Surname", nullable = true, length = 35)
    public String getSurname() {
        return surname;
    }

    public void setSurname(String surname) {
        this.surname = surname;
    }

    @Basic
    @Column(name = "Birthday", nullable = true)
    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        UserEntity that = (UserEntity) o;
        return Objects.equals(userId, that.userId) &&
                Objects.equals(name, that.name) &&
                Objects.equals(surname, that.surname) &&
                Objects.equals(birthday, that.birthday);
    }

    @Override
    public int hashCode() {
        return Objects.hash(userId, name, surname, birthday);
    }

    @OneToOne(mappedBy = "userByShopKeeperId")
    public UserIsShopkeeperEntity getUserIsShopkeeperByUserId() {
        return userIsShopkeeperByUserId;
    }

    public void setUserIsShopkeeperByUserId(UserIsShopkeeperEntity userIsShopkeeperByUserId) {
        this.userIsShopkeeperByUserId = userIsShopkeeperByUserId;
    }

    @OneToOne(mappedBy = "userByWorkerId")
    public UserIsWorkerEntity getUserIsWorkerByUserId() {
        return userIsWorkerByUserId;
    }

    public void setUserIsWorkerByUserId(UserIsWorkerEntity userIsWorkerByUserId) {
        this.userIsWorkerByUserId = userIsWorkerByUserId;
    }
}

И, наконец, это мой hibernate.cfg. xml файл:

Ошибка связана с типом поля Object для информационного поля в классе сущности ObjectEntity. Изменение на соответствующий тип решит проблему.

Также рассмотрите аналогичную проблему. org.hibernate.MappingException: сопоставление свойств имеет неправильное количество столбцов в сущности ENUM
