我启动服务器，我无法以任何方式填写列表，数据库已连接并工作，表工作，我无法从表中提取数据并与Hibernate表单建立连接
而如果我试着加上这样的话：异常错误：未知实体：ru.todolist.javafx.objects.Task
类任务休眠实现

public class TaskHibernateImpl implements TaskDao {
    ....
    public ObservableList<Task> tasks = FXCollections.observableArrayList();

        @SuppressWarnings("unchecked")
        @Override
        public ObservableList<Task> findAll() {
            System.out.println("tasks.isEmpty() = " + tasks.isEmpty());
    
            tasks.clear();
            Session session = getSessionFactory().openSession();
            tasks.addAll(session.createCriteria(Task.class).list()); //here it is not filled in
            System.out.println("tasks.isEmpty() = " + tasks.isEmpty()); // true list empty
            session.close();
            return tasks;
        }

我填写我的ObservableList，list，它是从表中得到的
正如您所看到的，todolist程序已经填充了x1c 0d1x
类TaskHibernateImpl在这个类中，数据是从表中取出的，方法tasksclear（）检查表的清除，这样就没有重复的表填充了，我们清除当前的一个。createQuery（“From Task”）这里我注意了！指定我的类实体

public class TaskHibernateImpl implements TaskDao { 
    ...
    public ObservableList<Task> findAll() {
                tasks.clear(); // 
                tasks.addAll(HibernateSessionFactoryUtil.getSessionFactory().openSession().createQuery("From Task").list());
                System.out.println("tasks.isEmpty() = " + tasks.isEmpty()); // false 
                return tasks;
            }
...
}

class HibernateSessionFactoryUtil -〉在这个类中，我创建了一个配置并向其中添加了一个类，其中包含一个JPA配置

public class HibernateSessionFactoryUtil {

    private static SessionFactory sessionFactory;

    private static ServiceRegistry serviceRegistry;

    public HibernateSessionFactoryUtil() {
    }

    public static SessionFactory getSessionFactory(){
        if(sessionFactory == null){
            try{
                Configuration configuration = new Configuration().configure();
                // here necessary class add
                configuration.addAnnotatedClass(ru.todolist.javafx.objects.Task.class);
                StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
                sessionFactory = configuration.buildSessionFactory(builder.build());
            } catch (Exception e) {
                System.out.println("Exception !" + e);
            }
        }
        return sessionFactory;
    }
}

class Task -〉在这个类中，我将JPA注解放置在@Entity、@Id、@Column中

package ru.todolist.javafx.objects;

import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
import javax.persistence.*;
import java.util.Date;

@Entity
@Table(name = "todo", schema = "main", catalog = "")
public class Task {

    private SimpleIntegerProperty id = new SimpleIntegerProperty();
    private SimpleStringProperty task = new SimpleStringProperty("");

    private static Date date = new Date();
    private SimpleStringProperty time = new SimpleStringProperty(date.toString());

//    private static boolean statusBegin = false;
    private static String statusText = "не выполнена";
    private SimpleStringProperty status = new SimpleStringProperty(statusText);

    public Task() {
    }

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Id
    @Column(name = "id", nullable = false)
    public int getId() {
        return id.get();
    }

    public SimpleIntegerProperty idProperty() {
        return id;
    }

    public void setId(int id) {
        this.id.set(id);
    }

    @Basic
    @Column(name = "task", nullable = false, length = -1)
    public String getTask() {
        return task.get();
    }

    public SimpleStringProperty taskProperty() {
        return task;
    }

    public void setTask(String task) {
        this.task.set(task);
    }

    @Basic
    @Column(name = "task_create_time", nullable = false, length = -1)
    public String getTime() {
        return time.get();
    }

    public SimpleStringProperty timeProperty() {
        return time;
    }

    public void setTime(String time) {
        this.time.set(time);
    }

    @Basic
    @Column(name = "status", nullable = true, length = -1)
    public String getStatus() {
        return status.get();
    }

    public SimpleStringProperty statusProperty() {
        return status;
    }

    public void setStatus(String status) {
        this.status.set(status);
    }

    @Override
    public String toString() {
        return "Task{" +
                "id=" + id +
                ", task=" + task +
                ", time=" + time +
                ", status=" + status +
                '}';
    }

}
