Why does hibernate want to insert a new entity with the same key if it already exists?

I am having the following problem. I have pushed my example into GitHub.
If I want to persist an instance of my class PlayerStatistics then Hibernate tries to create an already existing entity of Matchday (specified as #ManyToOne) which I do not want to but I do not seem to get around it.
I am persisting in the init method of DemoApplicationTests.
#Before
public void init() {
final Matchday matchday = matchdayRepository.save(new Matchday(1));
final Club club1 = clubRepository.save(new Club("Klub1"));
final Club club2 = clubRepository.save(new Club("Klub2"));
final Match match = matchRepository.save(new Match(matchday, club1, club2));
final Player player = playerRepository.save(new Player(1, "Jan", "Kowalski", club1));
playerStatisticsRepository.save(new PlayerStatistics(matchday, player, match));
}
If I have it like above, then I get the following exception.

If I debug the HQL I can clearly see that Hibernate wants to insert a new row into the table Matchday even if it already exists.
Hibernate:
insert
into
Matchday
(matchdayNumber)
values
(?)
If I comment the last line of the init() method then it works OK, so the problem has to be in this part: playerStatisticsRepository.save(new PlayerStatistics(matchday, player, match))
#Before
public void init() {
final Matchday matchday = matchdayRepository.save(new Matchday(1));
final Club club1 = clubRepository.save(new Club("Klub1"));
final Club club2 = clubRepository.save(new Club("Klub2"));
final Match match = matchRepository.save(new Match(matchday, club1, club2));
final Player player = playerRepository.save(new Player(1, "Jan", "Kowalski", club1));
//playerStatisticsRepository.save(new PlayerStatistics(matchday, player, match));
}
What am I doing wrong here?
PlayerStatistics class looks like that.
#Entity
#IdClass(PlayerStatisticsId.class)
public class PlayerStatistics implements Serializable {
//...
#Id
#ManyToOne(optional = false)
#PrimaryKeyJoinColumn
private Player player;
#Id
#ManyToOne(optional = false)
#PrimaryKeyJoinColumn
private Matchday matchday;
#ManyToOne(optional = false)
#JoinColumns({ #JoinColumn(name = "matchday_matchdaynumber", referencedColumnName = "matchday_matchdaynumber"),
#JoinColumn(name = "hometeam_name", referencedColumnName = "hometeam_name") })
private Match match;
#Column(nullable = false)
private boolean playedFromTheFirstWhistleblow;
#Min(0)
#Column(nullable = false)
private int enteredTheFieldAtInSeconds;
#Min(0)
#Column(nullable = false)
private int leftTheFieldAtInSeconds;
#ElementCollection(fetch = FetchType.EAGER)
#CollectionTable
#MapKeyEnumerated(EnumType.STRING)
private Map<ScoreType, Integer> statistics = new HashMap<>();
//...
}
EDIT
If I want to manage it directly from the Player entity on the other hand. Then I receive an exception that the entity is already associated with the session, while it does not seem to be.
#Before
public void init() {
final Matchday matchday = matchdayRepository.save(new Matchday(1));
final Club club1 = clubRepository.save(new Club("Klub1"));
final Club club2 = clubRepository.save(new Club("Klub2"));
final Match match = matchRepository.save(new Match(matchday, club1, club2));
final Player player = new Player(1, "Jan", "Kowalski", club1);
player.addPlayerStatistics(new PlayerStatistics(matchday, player, match));
playerRepository.save(player);
}

The problem here was in the PlayerStatisticsId and the way it was defined.
Originally it looked like this.
public class PlayerStatisticsId implements Serializable {
//..
private long player;
private int matchday;
public long getPlayer() {
return player;
}
public int getMatchday() {
return matchday;
}
#Override
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (obj instanceof PlayerStatisticsId) {
final PlayerStatisticsId o = (PlayerStatisticsId) obj;
return o.matchday == matchday && o.player == player;
} else {
return false;
}
}
}
I could have sworn that I read somewhere that only the primitives/basic types could be used in a class that is used for #ClassId. It does not seem to be the case though.
After changing it to
public class PlayerStatisticsId implements Serializable {
//...
private Player player;
private Matchday matchday;
public Player getPlayer() {
return player;
}
public Matchday getMatchday() {
return matchday;
}
#Override
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (obj instanceof PlayerStatisticsId) {
final PlayerStatisticsId o = (PlayerStatisticsId) obj;
return o.matchday.equals(matchday) && o.player.equals(player);
} else {
return false;
}
}
}
It does seem to work. I am receiving a completely different exception now but it is a case for a separate question.

Every time I think I fixed it, "Could not initialize a collection" error keeps coming back

I have a table relationship similar to the one described in this question I tried the way they said they'd fixed it there. Got this could not initialize a collection error. I looked around and changed it to have a third entity and the two original classes having Set with OneToMany mapping to that entity as opposed to using Map and ManyToMany mapping.
In case I'm just missing something stupid right in front of my face, here are my tables:
create table email_distribution_templates (
id number primary key,
from_address varchar2(50) not null,
subject varchar2(250) not null,
body varchar2(4000),
send_time date,
send_type varchar2(10),
email_type varchar2(50),
attachments_by varchar2(10),
attachment_info varchar2(50),
last_sent date,
CONSTRAINT unique_email_subject UNIQUE (subject)
);
create sequence distro_seq CACHE 50;
create table email_distribution_addressees (
id number primary key,
first_name varchar2(50),
last_name varchar2(50),
address varchar2(100) not null
);
create sequence addressee_seq CACHE 50;
create table addressees_for_distributions (
distro_id number not null references email_distribution_templates(id),
addressee_id number not null references email_distribution_addressees(id),
addressee_type varchar2(3) not null,
constraint adrs_fr_dist primary key(distro_id, addressee_id)
);
create sequence ad_fr_dst_seq CACHE 50;
And here are their corresponding entities:
#Entity
#Table(name = "email_distribution_templates")
#Cacheable
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
#SequenceGenerator(sequenceName = "distro_seq", name = "distro_seq", allocationSize = 1)
#Configurable(autowire = Autowire.BY_TYPE)
public class EmailDistributionTemplate implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "distro_seq")
private long id;
#OneToMany(fetch = FetchType.EAGER, mappedBy = "distro")
private Set<AddresseeForDistribution> addresseeForDistribution = Sets.newHashSet();
#NotNull

}
#Entity
#Table(name = "email_distribution_addressees")
#Cacheable
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
#SequenceGenerator(sequenceName = "addressee_seq", name = "addressee_seq", allocationSize = 1)
#Configurable(autowire = Autowire.BY_TYPE)
public class EmailDistributionAddressee implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "addressee_seq")
private long id;
#OneToMany(mappedBy = "addressee")
private Set<AddresseeForDistribution> addresseeForDistribution = Sets.newHashSet();
#Email
#NotNull
private String address;
private String firstName;
private String lastName;
//getters and setters
}
This is the entity that it is having problems forming a Set of in the EmailDistributionTemplate class:
#Entity
#Table(name = "addressees_for_distributions")
#Cacheable
#Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
#Configurable(autowire = Autowire.BY_TYPE)
public class AddresseeForDistribution implements Serializable {
private static final long serialVersionUID = 1L;
// #EmbeddedId
// private Id id;
#Id
private long id;
#ManyToOne(optional = false)
#JoinColumn(name = "distro_id", referencedColumnName = "id", insertable = false, updatable = false)
private EmailDistributionTemplate distro;
#ManyToOne(optional = false)
#JoinColumn(name = "addressee_id", referencedColumnName = "id", insertable = false, updatable = false)
private EmailDistributionAddressee addressee;
#Column(name = "addressee_type")
private AddresseeType addresseeType;
//getters and setters
}
As you can see, there are some commented out bits related to an embedded ID, I was getting the same error with that, so I thought I'd try without.
And here's the stacktrace:

I think Hibernate is becoming the bane of my existence. Any ideas or help would be greatly appreciated. I've been Googling and tinkering and trying to fix this error for a few days now. I feel like it's probably something dumb that I'm overlooking.

I figured out the problem by having Hibernate create the tables for me and comparing them to my scripts and code. It was something dumb that was right in front of my face. I missed an annotation for an enum in AddresseesForDistribution
I put the following code in a main method to have Hibernate generate the table creation for me and output it to the log/console:
Configuration config = new Configuration();
config.addAnnotatedClass(AddresseeForDistribution.class);
config.addAnnotatedClass(EmailDistributionAddressee.class);
config.addAnnotatedClass(EmailDistributionTemplate.class);
config.addAnnotatedClass(EmailSent.class);
config.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle10gDialect");
new SchemaExport(config).create(true,false); //the true tells it to output to the log/console, the false tells it to not actually touch the db
Thank you UweAllner for pointing me in that direction!

Hope you also declared mappings for annotated classes in hibernate.cfg.xml file.

I get this HibernateException in this line alhough my table has now two rows with the same id.
Diagnosis diagnosis = diagnosisRepository.findOne(diagnosisId);
Please anyone help me with my mistake. What can be probable error in my code.

Hy, It woks for me:
Seems I have two choices: either cascade all and delete orphan on the one-to-one relationship, or explicitly call my repository class to look up and save the original Sheet every time I remove its relationship with Plate. I opted for the first choice and added this to the plate class:
#OneToOne(mappedBy = "plate", cascade = CascadeType.ALL, orphanRemoval = true)
https://stackoverflow.com/a/32636186/3255595

From Spring documentation:
T findOne(ID id)
Retrieves an entity by its id.
Seem that diagnosisId is not a primary key.

it sounds like you have more than one row in the database with the same id values!
Are you sure your id is really unique in the DB ?
Hibernate Exception
More than one row with the given identifier was found: 2, for class: com.zurelsoft.ipr.model.Diagnosis
tells that hibernate query executes returns more than one row (i.e 2) of class Diagnosis Please enable SQL logging and execute the select by hand and see what it returns

After each Clean and Build or Compiling of any file I'm getting above exception while accessing any page. To resolve this issue each time I have to restart the glassfish server. Since, this won't be good solution. So, anyone help me to resolve this issue ?

Restart the server then Clean, Build and Deploy your project this how i solved the problem

It seems I resolved my issue. I found this link
And added following code in my class where I'm creating instance of EMF
#PreDestroy
public void destruct()
{
emf.close();
}
and #override servlet destroy method and call above method. Now, It works.!!!

I'm a beginner, and got the same problem. After some days debugging I found out that my problem was the ID field in my MySQL table. It wasn't set as auto-increment. After changing that, problem solved.
Maybe it can be others beginners problem, too.

How to handle Bean Validation Exceptions

I have a class according to:
#Entity
public class Car {
#Id
#GeneratedValue
private Long id;
#NotNull
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "OWNER_ID")
private Owner owner;
#NotNull()
#Column(nullable = false)
private String make;
#NotNull()
#Column(nullable = true)
private String model;
#Column(nullable = false)
private String gears;
// More fields
Say I am trying to percist the object and one field, make field for instance, is null which is not supposed to be. Following exceptions is thrown:

Caused by: javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'. Please refer to embedded ConstraintViolations for details.
What I would like to do is to find a best practice to validate the entity before persist it in the database. Sure, I could implement a help method inside the entity class something like:
public boolean validate() {
if(owner == null) {
return false;
}
if(make == null) {
return false;
}
if(model == null) {
return false;
}
return true;
}
But that does not feel as the right approach. Can you please guide me?
Best regards

You can and should validate the entity before persisting like this and return an appropriate error:
Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<Car>> constraintViolations = validator.validate(myCar);
if (constraintViolations.size() > 0) {
Set<String> violationMessages = new HashSet<String>();
for (ConstraintViolation<T> constraintViolation : constraintViolations) {
violationMessages.add(constraintViolation.getPropertyPath() + ": " + constraintViolation.getMessage());
}
throw new RuntimeException("Car is not valid:\n" + StringUtils.join(violationMessages, "\n"));
}
