You should change the findByUserIdOrderByScoreTimestampDesc to findByUserIdOrderByScoreTimeStampDesc.
Explanation: The properties of Entity Class must match with the Default Naming Strategy (unless configured specifically.)
I hope, this works.
Your Entity class is having property name as scoreTimeStamp (s in capital for timestamp word), but in Method Declaration, it is ScoreTimestamp (s in lowercase for timestamp word).
PS: By the information you provided in Question and following comments, this should only be the problem.
I am beginner using java and spring jpa (expecially Jhipster). I want to create object in object like this :
But I always get like this :
property buildingsDTO always empty, this is my code, please correct my code in order I get like first picture.

please anyone help me.

By default jHipster will mark any OneToMany entity relationships as #JsonIgnore so that the Set of buildings is not returned in the JSON:
#OneToMany(mappedBy = "location")
#JsonIgnore
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<Building> buildings = new HashSet<>();
If you want this to show up in the JSON then you should remove that annotation and also mark it with an eager loading strategy so that the set of buildings are loaded as you expect:
#OneToMany(mappedBy = "location", fetch = FetchType.EAGER)
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<Building> buildings = new HashSet<>();
Someone can please suggest me how I can do equals and hashCode methods of these entities?
This is a many-to-many relationship between a Gara (Contest) and Agenzia (Agency):
One contest has many Agency, one Agency can be in more Contest.
I tried some implementations but or I get Stackoverflow error, or,
when I'm updating a Gara (Contest), I can't update the set of Agenzie (Agencies) because i get this error:
org.springframework.dao.DuplicateKeyException: a different object with
the same identifier value was already associated with the session:
[com.myApp.model.GaraAgenzia#com.mmyApp.model.GaraAgenziaId#49f];
nested exception is org.hibernate.NonUniqueObjectException: a
different object with the same identifier value was already associated
with the session:
[com.myApp.model.GaraAgenzia#com.myApp.model.GaraAgenziaId#49f]
when i try to do an update.
thanks

Edit 1:
If i clear the set of Agencies (and Services) before
set again it:
garaToUpdate.getGaraAgenzie().clear();
garaToUpdate.getGaraServizi().clear();
getCurrentSession().flush();
garaToUpdate.setGaraAgenzie(gara.getGaraAgenzie());
garaToUpdate.setGaraServizi(gara.getGaraServizi());
getCurrentSession().update(garaToUpdate);
i get this error:
A collection with cascade="all-delete-orphan" was no longer
referenced by the owning entity instance:
Edit 2:
As suggested by #JamesB, i added the toString method to GaraAgenzia and GaraAgenziaId. Here the result BEFORE update the Gara record:
this is the record taken from db just before update it
INFO : com.machinet.model.GaraAgenziaId - garaToUpdate.GaraAgenzie
(before update): [GaraAgenzia [numeroContratti=0, pk=GaraAgenziaId
[Gara=Gara [titolo=gara title, obiettivo=999, bonus=100.00,
dataIniziale=2014-07-31, dataFinale=2014-07-31], agenzia=Agenzia(id=1,
nome='Agency 1 ltd', ragione sociale=Agency 1 ltd srl)]]]
this is the edited record that will be set in db:
INFO : com.machinet.model.GaraAgenziaId - editedGara.GaraAgenzie
(before update): [GaraAgenzia [numeroContratti=0, pk=GaraAgenziaId
[Gara=Gara [titolo=gara title, obiettivo=999, bonus=100.00,
dataIniziale=2014-07-31, dataFinale=2014-07-31], agenzia=Agenzia(id=1,
nome='Agency 1 ltd', ragione sociale=Agency 1 ltd srl]]]
These seem to work well. I post hoping someone will find it useful:
GaraAgenzia class:
public boolean equals(Object o) {
if (this== o) return true;
if (o ==null|| getClass() != o.getClass()) return false;
GaraAgenzia that = (GaraAgenzia) o;
if (getPk() !=null?!getPk().equals(that.getPk()) : that.getPk() !=null) return false;
return true;
}
public int hashCode() {
return (getPk() !=null? getPk().hashCode() : 0);
}
GaraAgenziaId class:
public boolean equals(Object o) {
if (this== o) return true;
if (o ==null|| getClass() != o.getClass()) return false;
GaraAgenziaId that = (GaraAgenziaId) o;
if (gara !=null?!gara.equals(that.gara) : that.gara !=null) return false;
if (agenzia !=null?!agenzia.equals(that.agenzia) : that.agenzia !=null)
return false;
return true;
}
public int hashCode() {
int result;
result = (agenzia !=null? agenzia.hashCode() : 0);
result =31* result + (gara !=null? gara.hashCode() : 0);
return result;
}
It is not an exactly answer, but may help someone in a similar problem. I made a abstract class that is extended by all the entities. This way I don't need to implement these methods in all entities.
public abstract class GenericEntity implements Serializable{
protected static final long serialVersionUID = 1L;
abstract public Serializable getId();
#Override
public int hashCode()
{
return (getId() == null) ? System.identityHashCode(this) : getId().hashCode();
}
#Override
public boolean equals(Object obj)
{
if (this == obj)
return true;
if (obj == null)
return false;
if (this.getClass() != obj.getClass())
return false;
if (org.hibernate.Hibernate.getClass(this) != org.hibernate.Hibernate.getClass(obj))
return false;
GenericEntity other = (GenericEntity) obj;
if (getId() == null || other.getId() == null)
return false;
return getId().equals(other.getId());
}
}
I think in your case you could put it in your BaseEntity.

why the sql is so many? i want the first sql,and get the MachineSalesReport ,include the customerInformation and InternalInformation and InstallInformation
I have a basic problem with my oracle database table whereas I use JPA.
My problem is, I create the table in the database by adding it an ID column. When I turn back to my JPA project, and when I try to create new entry it doesn't create ID for the new one. It always says: An error occurred attempting to roll back the transaction.
I search about the issue. It basically doesn't auto-generate the ID value. Here is my JPA controller class:
#Entity
#Table(name = "PROJECTS", catalog = "", schema = "PROJETAKIP")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Projects.findAll", query = "SELECT p FROM Projects p"),
#NamedQuery(name = "Projects.findById", query = "SELECT p FROM Projects p WHERE p.id = :id"),
#NamedQuery(name = "Projects.findByProject", query = "SELECT p FROM Projects p WHERE p.project = :project")})

When I assign the ID manually it works perfectly. But what I want is, it has to auto-generate the value. How to overcome this?
my trigger: DELIMITER ##
CREATE OR REPLACE TRIGGER PROJETAKIP.PROJECTS_TRIGGER BEFORE INSERT ON PROJECTS REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT PROJECTS_SEQUENCE.nextval INTO :NEW.ID FROM dual;END; ##
DELIMITER ;
Sequence startegy
This is how you should use the sequence generator:
#GeneratedValue(strategy= GenerationType.SEQUENCE, generator="seq")
And on the class: (eg. after the #Entity)
#SequenceGenerator(name="seq", sequenceName="PROJECTS_SEQUENCE", initialValue=1)
This should work for you.
While saving the object i had the same error.
My reason was because of adding MIN range of 3 digits to id value.
By default auto generated id will start from 1, 2, 3 ...
I did:
#Id #GeneratedValue
#Basic(optional = false)
#Size(min = 1, max = 64, message = "ID must be between 1 and 64 characters")
private String id;
So - in your case - be careful with your id annotations - try to launch without scale, min and max values - see the result. For example, try:
#Id
#Basic(optional = false)
#Column(name = "ID")
#GeneratedValue(strategy= GenerationType.AUTO)
private BigDecimal id;
