Columns are not populating in tableview on javafx - java

I have been trying to make the columns show a string of paciente and empleado but still they show empty, the other columns are fine, they show what they supposed to show, but these 2 (paciente and empleado) are still empty. I thought it was because of their properties, that they have different names, i tried that and still they came up empty, can i have some tips on how to do it the right way?
columnaCitasFecha.setCellValueFactory(new PropertyValueFactory<Cita, Date>("fecha"));

You need:
TableColumn<Cita, String> columnaCitasPaciente ;
// ...
columnaCitasPaciente.setCellValueFactory(cellData ->
new SimpleStringProperty(cellData.getValue().getPaciente().getNombrePaciente()));
columnaCitasDentista.setCellValueFactory(cellData ->
new SimpleStringProperty(cellData.getValue().getEmpleado().getNombreEmpleado());

Issues with JPA and Hibernate library when perform count statement

For the previous week or so, I have been fruitlessly trying to get this JPA library to work.
I can perform simple queries, e.g. find entity by id, or get a collection of entities, etc, however, when I try to perform more complex queries, I always seem to be encounter an error. Can someone please help with debugging this COUNT statement which produces the following stack trace of errors:
Caused by: org.hibernate.query.sqm.InterpretationException: Error interpreting query [SELECT COUNT(a.id) FROM AgreementEntity a]; this may indicate a semantic (user query) problem or a bug in the parser
Caused by: java.lang.NullPointerException
Here is the code which causes the error:
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("SELECT COUNT(a.id) FROM AgreementEntity a");
And here is the entire AgreementEntity class:

}
public void setTierReportResultsById(Collection<TierReportResultEntity> tierReportResultsById) {

}
}

You can try count(a) instead of a.id
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("select count(a) from AgreementEntity a ");

Same problem here with count function and group by. I downgraded to 5.4.10.Final version to make it work.

The issue was that I was using an alpha build of the hibernate library instead of a stable build.

hibernate: Use of #OneToMany or #ManyToMany targeting an unmapped class

I'm using hibernate-core in a maven project and I want to create the entities for the following database: db_schema
I'm just starting to learn hibernate, so please bear with me on this one. I know that it might be a stupid mistake but I just can't figure it out.
I'm getting the following exception when I try to test the code:
org.hibernate.AnnotationException: Use of #OneToMany or #ManyToMany targeting an unmapped class: entity.User.groups[entity.IsIn]

I've been looking on Stack for a solution on similar issues but the suggestions did not help in my case. I'm kinda stuck right now.
Any help will be highly appreciated. Thank your for your time.

Spring data Join multiple tables

This is it my database project:
I have a problem with the correct combination of tables, as it is in the picture.
This is my files:
Category.java
#Entity
public class Category {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
private String categoryName;
protected Category() {}
public Category(String categoryName) {
this.categoryName = categoryName;
}
public String getCategoryName() {
return categoryName;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public void setCategoryName(String categoryName) {
this.categoryName = categoryName;
}
#Override
public String toString() {
return String.format(
"Customer[id=%d, firstName='%s']",
id, categoryName);
}
}
Items.java
#Entity
#Table(name = "Items")
public class Items {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private int ItemId;
private String ItemName;
private String price;
private Set<Locals> locals = new HashSet<Locals>(0);
public Items(){
}
public Items(String price, String itemName) {
this.price = price;
this.ItemName = itemName;
}
public void setItemId(int itemId) {
ItemId = itemId;
}
public void setLocals(Set<Locals> locals) {
this.locals = locals;
}
public void setPrice(String price) {
this.price = price;
}
public void setItemName(String itemName) {
ItemName = itemName;
}
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "ItemId", unique = true, nullable = false)
public int getItemId() {
return ItemId;
}
#ManyToMany(fetch = FetchType.LAZY, mappedBy = "itemsTo")
public Set<Locals> getLocals() {

}
#Column(name = "price", nullable = false, length = 10)
public String getPrice() {

}
#ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)

inverseJoinColumns = { #JoinColumn(name = "ItemId",
nullable = false, updatable = false) })
public Set<Items> getItemsTo() {
return itemsTo;
}
}
and ItemsFinall.java
#Entity
#Table(name = "ItemsFinall")
public class ItemsFinall {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private int id;
private int ItemId;
private int CategoryId;
private int LocalId;
public ItemsFinall(int id, int localId, int categoryId, int itemId) {
this.LocalId = localId;
this.CategoryId = categoryId;
this.ItemId = itemId;
this.id=id;
}
public void setId(int id) {
this.id = id;
}
public void setLocalId(int localId) {

}
public int getCategoryId() {

public int getId() {

}
}
I get the following error: Caused by: org.springframework.data.mapping.PropertyReferenceException: No property categoryName found for type ItemsFinall!
I do not know what to do to properly connect the table.
ItemsServiceImpl.java
package dnfserver.model;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**

#Component
public class CategoryServiceImpl implements CategoryService {
#Autowired
private CategoryRepository categoryRepository;
private Map<Integer,String> categoryMap = new HashMap<Integer, String>();
#Override
public Category create(Category category) {
Category createdCategory = category;
return categoryRepository.save(createdCategory);
}
#Override
public Category delete(int id) {
return null;
}
#Autowired
public Map<Integer,String> findAll(){
int i=0;
for (Category cat : categoryRepository.findAll()) {
categoryMap.put(i,cat.toString());
i++;
}
return categoryMap;
}
#Override
public Category update(Category shop) {
return null;
}
#Override
public Category findById(int id) {
return categoryRepository.findOne(id);
}
}

In hibernate/JPA you model the relationship between Entities, but not use plain Ids!
For example
#Entity
#Table(name = "ItemsFinall")
public class ItemsFinall {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private int id;
//instead of: private int ItemId;
#OneToMany
private Item item;
//instead of: private int CategoryId;
#OneToMany
private Category category;
//instead of: private int LocalId;
#OneToMany
private Local local;
...
(You also need to fix the Set<Locals> locals in item)

How to prevent endless loop in hibernate

I have a rest server and client which uses this API. I have a list of hotels and it had passed well until I added bidirectional dependencies to other entities.After that I start receive an endless array of entities which just repeat the same row in database.
It is my first project with hibernate so may be I made trivial mistakes of novice.
Hotel:
#Entity
#Table(name = "hotels", schema = "", catalog = "mydb")
public class HotelsEntity implements HospitalityEntity{
private int idHotel;
private String name;
private String region;
private String description;
// private byte[] photo;
private HotelPropertyEntity property;
private List<RoomEntity> rooms;
#OneToOne(mappedBy = "hotel")
public HotelPropertyEntity getProperty() {
return property;
}
public void setProperty(HotelPropertyEntity property) {
this.property = property;
}
#OneToMany(mappedBy = "hotel")
public List<RoomEntity> getRooms() {
return rooms;
}
public void setRooms(List<RoomEntity> rooms) {
this.rooms = rooms;
}
#Id
#Column(name = "id_hotel", unique = true)
#GeneratedValue(strategy=GenerationType.AUTO)
public int getIdHotel() {
return idHotel;
}
public void setIdHotel(int idHotel) {
this.idHotel = idHotel;
}
#Basic
#Column(name = "name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Basic
#Column(name = "region")
public String getRegion() {
return region;
}
public void setRegion(String region) {
this.region = region;
}
#Basic
#Column(name = "description")
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
HotelProperty
#Entity
#Table(name = "hotel_property", schema = "", catalog = "mydb")
public class HotelPropertyEntity {
private int idHotelProperty;
private byte hasPool;
private byte hasTennisCourt;
private byte hasWaterslides;
private HotelsEntity hotel;
#Id
#Column(name = "id_hotel_property", unique = true)
#GeneratedValue(strategy=GenerationType.AUTO)
public int getIdHotelProperty() {
return idHotelProperty;
}
public void setIdHotelProperty(int idHotelProperty) {
this.idHotelProperty = idHotelProperty;
}
#Basic
#Column(name = "has_pool", columnDefinition = "BIT", length = 1)
public byte getHasPool() {
return hasPool;
}
public void setHasPool(byte hasPool) {
this.hasPool = hasPool;
}
#Basic
#Column(name = "has_tennis_court", columnDefinition = "BIT", length = 1)
public byte getHasTennisCourt() {
return hasTennisCourt;
}
public void setHasTennisCourt(byte hasTennisCourt) {
this.hasTennisCourt = hasTennisCourt;
}
#Basic
#Column(name = "has_waterslides", columnDefinition = "BIT", length = 1)
public byte getHasWaterslides() {
return hasWaterslides;
}
public void setHasWaterslides(byte hasWaterslides) {
this.hasWaterslides = hasWaterslides;
}
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "id_hotel_property")
public HotelsEntity getHotel() {
return hotel;
}
public void setHotel(HotelsEntity hotel) {
this.hotel = hotel;
}
Room:
#Entity
#Table(name = "room", schema = "", catalog = "mydb")
public class RoomEntity {
private int idRoom;
private String roomType;
private int peopleCapacity;
private Boolean booked;
private Boolean locked;
private HotelsEntity hotel;
private InventoriesEntity inventory;
private RoomPropertyEntity roomProperty;
#OneToOne(mappedBy = "room")
public RoomPropertyEntity getRoom() {
return roomProperty;
}
public void setRoom(RoomPropertyEntity roomProperty) {
this.roomProperty = roomProperty;
}
#OneToOne
#JoinColumn(name = "id_room")
public InventoriesEntity getInventory() {
return inventory;
}
public void setInventory(InventoriesEntity inventory) {
this.inventory = inventory;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "id_hotel")
public HotelsEntity getHotel() {
return hotel;
}
public void setHotel(HotelsEntity hotel) {
this.hotel = hotel;
}
#Id
#Column(name = "id_room")
public int getIdRoom() {
return idRoom;
}
public void setIdRoom(int idRoom) {
this.idRoom = idRoom;
}
#Basic
#Column(name = "room_type")
public String getRoomType() {
return roomType;
}
public void setRoomType(String roomType) {
this.roomType = roomType;
}
#Basic
#Column(name = "people_capacity")
public int getPeopleCapacity() {
return peopleCapacity;
}
public void setPeopleCapacity(int peopleCapacity) {
this.peopleCapacity = peopleCapacity;
}
#Basic
#Column(name = "booked", columnDefinition = "BIT", length = 1)
public Boolean getBooked() {
return booked;
}
public void setBooked(Boolean booked) {
this.booked = booked;
}
#Basic
#Column(name = "locked", columnDefinition = "BIT", length = 1)
public Boolean getLocked() {
return locked;
}
public void setLocked(Boolean locked) {
this.locked = locked;
}
Could you please advise what is a way or ways to tell hibernate to stop this cycle?
p.s
This code contains another one issue. I f I remove one to one dependency and remain only one to many I receive failed to lazily initialize a collection of role: com.example.model.HotelsEntity.rooms, could not initialize proxy - no Session (through reference chain: java.util.ArrayList[0]->com.example.model.HotelsEntity["rooms"])

You need to mark entity as not serializable for JSON. Please use #JsonIgnore or #JsonIgnoreProperties("field") on one of the sides of the relations (the annotation is class-level).
