Файл Post.java:

package com.example.blog2.models;


import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Post {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String title, anons, full_text;
    private int views;


    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAnons() {
        return anons;
    }

    public void setAnons(String anons) {
        this.anons = anons;
    }

    public String getFull_text() {
        return full_text;
    }

    public void setFull_text(String full_text) {
        this.full_text = full_text;
    }

    public int getViews() {
