Hibernate doesn't insert record to database

Hibernate doesn't insert record to database - java

I try to add a record to the database. In debug, I check to create object and object created is good. When I use getCurrentSession().save(entity); this doesn't add a record to the database but the session is open. I have a composite foreign key, to create this key I create an extra class.
class:
package nba_statistics.entities;
import org.hibernate.annotations.Cascade;
import javax.persistence.*;
#Entity(name = "PlayerMatchPositions")
#Table(name = "player_match_positions")
public class PlayerMatchPositions {
public void setId(PlayerMatchPositionsId id) {
this.id = id;
}
#EmbeddedId
private PlayerMatchPositionsId id;
#ManyToOne
#MapsId("player_id")
#Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)
#JoinColumn(name = "player_id")
private Players player;
#ManyToOne
#MapsId("match_id")
#Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)
#JoinColumn(name = "match_id")
private Matches match;
#ManyToOne
#MapsId("position_id")
#Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)
#JoinColumn(name = "position_id")
private Positions position;
public PlayerMatchPositions(){};
public PlayerMatchPositions(Players player, Matches match, Positions position) {
id = new PlayerMatchPositionsId();
this.player = player;
this.match = match;
this.position = position;
}
public Players getPlayer() {
return player;
}
public void setPlayer(Players player) {
this.player = player;
}
public Matches getMatch() {
return match;
}
public void setMatch(Matches match) {
this.match = match;
}
public Positions getPosition() {
return position;
}
public void setPosition(Positions position) {
this.position = position;
}
#Override
public String toString() {
return "PlayerMatchPositions{" +
"id=" + id +
", player=" + player +
", match=" + match +
", position=" + position +
'}';
}
}
Extra class to foreign key:
package nba_statistics.entities;
import javax.persistence.Column;
import javax.persistence.Embeddable;
import java.io.Serializable;
import java.util.Objects;
#Embeddable
public
class PlayerMatchPositionsId implements Serializable {
#Column(name = "player_id")
int playerId;
#Column(name = "match_id")
int matchId;
#Column(name = "position_id")
int positionId;
public PlayerMatchPositionsId(){}
public PlayerMatchPositionsId(int playerId, int matchId, int positionId) {
this.playerId = playerId;
this.matchId = matchId;
this.positionId = positionId;
}
public int getPlayerId() {
return playerId;
}
public void setPlayerId(int playerId) {
this.playerId = playerId;
}
public int getMatchId() {
return matchId;
}
public void setMatchId(int matchId) {
this.matchId = matchId;
}
public int getPositionId() {
return positionId;
}
public void setPositionId(int positionId) {
this.positionId = positionId;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof PlayerMatchPositionsId)) return false;
PlayerMatchPositionsId that = (PlayerMatchPositionsId) o;
return Objects.equals(playerId, that.playerId) &&
Objects.equals(positionId, that.positionId)&&
Objects.equals(matchId, that.matchId);
}
#Override
public int hashCode() {
return Objects.hash(playerId, positionId, matchId);
}
}
Dao:
package nba_statistics.dao.classes;
import nba_statistics.dao.interfaces.IPlayerMatchPositionsDao;
import nba_statistics.entities.*;
public class PlayerMatchPositionsDao extends Dao implements IPlayerMatchPositionsDao {
public void persist(PlayerMatchPositions entity) {
getCurrentSession().save(entity);
}
#Override
public int getData(Players player, Matches match, Positions position){
if(player == null)
{
return 1;
}
if(match==null)
{
return 2;
}
if(position==null)
{
return 3;
}
PlayerMatchPositions playerMatchPositions = new PlayerMatchPositions();
playerMatchPositions.setPlayer(player);
playerMatchPositions.setMatch(match);
playerMatchPositions.setPosition(position);
playerMatchPositions.setId(new PlayerMatchPositionsId(player.getId(),match.getId(),position.getId()));
persist(playerMatchPositions);
return 0;
}
}
In other class, I do it similar and all is good, only in this class, it doesn't add to the database.

Custom TiledDataSource with paging library

I tried to implement custom TiledDataSource for using with paging library. When I used LivePagedListProvider like returns type for my Dao method it worked fine (after table items updating - ui updated automatically).
#Query("SELECT * FROM " + Table.States.PLAY_STATE + ", "+Table.Chart.ARTIST+ " ORDER BY position ASC")
LivePagedListProvider<Artist> loadArtists();
But when I try implement custom TiledDataSource for LivePagerListProvider table updates not triggered my observers.
Abstract generic class:
public abstract class PagedNetworkBoundResource<ResultType, RequestType> extends TiledDataSource<ResultType> {
#Override
public int countItems() {
return DataSource.COUNT_UNDEFINED;
}
#Override
public List<ResultType> loadRange(int startPosition, int count) {
fetchFromNetwork(startPosition, count);
return loadFromDb(startPosition, count);
}
#WorkerThread
private void fetchFromNetwork(int startPosition, int count) {
if (createCall(startPosition, count) != null)
try {
Response<RequestType> response = createCall(startPosition, count).execute();
if (response.isSuccessful() && response.code() == 200) {
saveCallResult(response.body());
}
} catch (IOException e) {
e.printStackTrace();
}
}
#WorkerThread
protected abstract void saveCallResult(#NonNull RequestType item);
#WorkerThread
protected abstract List<ResultType> loadFromDb(int startPosition, int count);
#WorkerThread

public LiveData<PagedList<ResultType>> getAsLiveData() {

My dao method for this case:
#Query("SELECT * FROM " + Table.States.PLAY_STATE + ", "+Table.Chart.ARTIST+ " ORDER BY position ASC LIMIT (:limit) OFFSET (:offset)")

}
}
For each Artist items I add fields from PlayerStateEntity (not good solution but this easy way to represent state of ui items). After PlayerStateEntity table updates Room should notify about data changes, but doesn't do it.
I understand that Room doesn't know about query what I used, and can't updates my RecyclerView which provide by paging library. But maybe some one knows how to notify Room about tables which I used inside mine DataSource for future triggering ui updates?

The problem was related with custom DataSource realization. When data has changed, LivePagedListProvider should create a new DataSource instance for right ui updating. I used the same instance, so my previous solution is not right.

failed to lazily initialize a collection of role ManyToMany relation

I have an entity question and an entity test with ManyToMany relationship between the two entitie.
when I want to view the questions of a test this error is occurred.

When you get Test and access Test.questions later, after leaving the transaction, you will get a lazy initialization exception when the Test entity is detached and questions has not been initialized/fetched yet. You can either do a specific fetch, or depending on your configuration, you can call Test.getQuestions().size() before you exit the transaction.

SPRING JPA - org.hibernate.PersistentObjectException: detached entity passed to persist:

I've been stuck here for almost a week trying find the answer on the internet but sadly nothing worked. :( Everytime I try to update using this method:
private Tenant updateTenantWithApplicationProperties(List<TenantApplicationProperty> newTenantApplicationProperties, String tenantId) {
String reason = "Update application properties.";
Tenant existingTenant = tenantRepository.findById(tenantId);
List<TenantApplicationProperty> temp = existingTenant.getTenantApplicationProperties();
existingTenant.setTenantApplicationProperties(newTenantApplicationProperties);
setApplicationPropertiesUpdateValues(temp, existingTenant);
if(newTenantApplicationProperties != null && newTenantApplicationProperties.size() != 0) {
Tenant savedTenantWithAppProps = saveTenantWithLog(existingTenant, reason);
return savedTenantWithAppProps;
}
return existingTenant;
}
Im always getting this error:

In application property, you defined 1-1 relation like:
#OneToOne
#JoinColumn(name = "property_group_id")
private ApplicationPropertyGroup applicationPropertyGroup;
#OneToOne
#JoinColumn(name = "property_type_id")
private ApplicationPropertyType applicationPropertyType;
While you have not defined the same relation (note it should work bidirectionally i.e. say for e.g. if you as a person related to an employee id, then employee id is related to you as a person well) in individual property ApplicationPropertyGroup and ApplicationPropertyType.
You should add the same 1-1 relation in ApplicationPropertyGroup and ApplicationPropertyType with ApplicationProperty.

ebean model update not permanent

Good day! I'm having a problem when updating an entity. When I click the "update" button, the changes are saved. However, when I go a different page, the recently changed (or added) items are there but the old items (that should be changed or removed) are also there. Particularly the relatedTags (the name and notes are updating just fine). Why is it not persistent or permanent?
Here is where the updating happens.
Form<Tag> filledForm = tagForm.fill(Tag.find.byId(id)).bindFromRequest();
Tag editedTag = RelatedTag.findTag(id);
if(filledForm.hasErrors()) {
return badRequest(editTagForm.render(user, editedTag, filledForm, tags));
}
else {
List<RelatedTag> relatedTagsAlloc = new ArrayList<RelatedTag>();
java.util.Map<String, String[]> map = request().body().asFormUrlEncoded();
String[] relatedTags = map.get("relatedTags.tag.name");
String[] relationship = map.get("relatedTags.relationship");
String[] relatedNotes = map.get("relatedTags.relatedNotes");
if (relatedTags != null) {
for (int i = 0; i < relatedTags.length; i++) {
if (RelatedTag.exists(relatedTags[i].trim().toLowerCase().replaceAll("\\s+", " "))) {
relatedTagsAlloc.add(RelatedTag.findByLabel(
relatedTags[i].trim().toLowerCase().replaceAll("\\s+", " "), relationship[i], relatedNotes[i].trim()));
} else {
Tag unknown = new Tag(relatedTags[i], "");
Tag.create(unknown);
relatedTagsAlloc.add(RelatedTag.findByLabel(
relatedTags[i].trim().toLowerCase().replaceAll("\\s+", " "), relationship[i], relatedNotes[i].trim()));
}
}
editedTag.getRelatedTags().clear();
}
editedTag.setName(filledForm.get().getName().toLowerCase().replaceAll("\\s+", " "));
editedTag.setRelatedTags(relatedTagsAlloc);
editedTag.update();
Application.log(user, editedTag, action);
writeToFile(editedTag);
return ok(summary.render(user, editedTag));
}
And here are the models:
