I want to get a list of results using the query as below:
SELECT x FROM XTreinamentosOrc x WHERE x.codEduca NOT IN (SELECT DISTINCT y.codCurso y FROM XRlz y WHERE y.matricula = :matricula)
I have used it in its entity class, but then I've got the Exception:
Caused by: javax.el.PropertyNotFoundException: The class 'br.com.bb.upb.diage.atb_treinamentos.entities.XTreinamentosOrc' does not have the property 'matricula'.
The matricula field is obtained when the user successfully logs in the app.
It should be setted in the NamedQuery via CDI to query the database.
The matricula field is located in another table different from the one mapped here.
How can I set the injected sessionChave String in parameter matricula, which is of XRlzConsolidado class type?
The bean:
#Named(value = "ExtratoBean")
#RequestScoped
public class ExtratoBean implements Serializable {
#EJB
private XTreinamentosOrcFacade xt;
#Inject
#SessionChave
private String sessionChave;
private List<XTreinamentosOrc> xTreinamentosOrcList;
public List<XTreinamentosOrc> getxTreinamentosOrcList() {
return QueryExtratoTreinamentos();
}
private List QueryExtratoTreinamentos() {
List<XTreinamentosOrc> extratoTreinamentosOrcList = null;
XRlzConsolidado x = new XRlzConsolidado();
x.setMatricula(sessionChave);
extratoTreinamentosOrcList = xt.findAllTreinamentosByMatricula(x);
return extratoTreinamentosOrcList;
}
}
There are 3 entities: XRlz, XRlzConsolidado and XTreinamentosOrc.

return true;
}
}
Thanks in advance.
I believe the problem lies in the name of your query. findAllTreinamentosByMatricula() is a Property Expression and can refer only to a direct property of the managed entity. findAllTreinamentosByMatricula will look in the XTreinamentosOrc class for the property called matricula. When that property is not found in XTreinamentosOrc you get the exception:
Caused by: javax.el.PropertyNotFoundException: The class 'br.com.bb.upb.diage.atb_treinamentos.entities.XTreinamentosOrc' does not have the property 'matricula'.
You need to change the name of your query to something like:
#NamedQuery(name = "XTreinamentosOrc.find", query = "SELECT x FROM XTreinamentosOrc x WHERE x.codEduca NOT IN (SELECT DISTINCT y.codCurso FROM XRlz y WHERE y.matricula = :matricula)")})
(I may be off with the method name 'find() so you may need to do some more research' for acceptable format)
check out this documentation:
http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods.query-property-expressions
Could you post code for XRlzConsolidado? It probably contains a string field you want to compare with sessionChave. You are comparing field XRlz.matricula with string value, but it is of type XRlzConsolidado

I am trying make sort on backend by columns. For sorting I use
final SpecificationUtil gardenSpecification = new SpecificationUtil<>();
final List<Specification<Garden>> searchSpecification = gardenSpecification.createSearchSpecificationRaw(request);
final Specification<Garden> specificationResult = searchSpecification.stream().reduce(null, Specification::and);
Sort.Direction direction = Sort.Direction.ASC;
if (request.getOrderDirection().equals("desc")) {
direction = Sort.Direction.DESC;
}
return gardenDataService.findAll(specificationResult, Sort.by(direction, request.getOrderColumn()));
public List<Specification<T>> createSearchSpecificationRaw(DataGridRequest request) {
final List<Specification<T>> specifications = new ArrayList<>();
if (request.getSearchColumns() != null && !request.getSearchColumns().isEmpty()) {
for (ColumnSearch search : request.getSearchColumns()) {
if (StringUtils.isEmpty(search.getSearchValue())) {
continue;
}
specifications.add(create(search.getColumnName(), search.getSearchValue()));
}
}
return specifications;
}
/**

* #param value
* #return
*/
private Specification<T> create(String columnKey, String value) {
final GenericSpecificationFactory<T> specificationFactory = new GenericSpecificationFactory<>();
return specificationFactory.createLike(columnKey, value);
}
when I sort by column in Garden, sorting is OK. But when I want sort by lastName I get error:
org.springframework.data.mapping.PropertyReferenceException: No property lastName found for type Garden!
Can you help me how the best make sorting on connected column from another entity.
Thank you.

I use
hibernate v. 5.4.13.Final
spring-boot v. 2.2.5.RELEASE
gradle
java 1.8
lombok
The changes are very minor like before I was using maven, SessionFactory for hibernate, traditional getters and setter.
I saw some similar issues where NamingStrategy was a problem during migration between hibernate 4 and 5, but this code works on the first project where hiberante is 5.4.10.Final.
I like IdClass because I have access to personId as primitive value and don't have to load data from object person.
I saw similar issues without insertable = false,updatable = false but I have it...
Simmilar issue found here
The solution
The issue was on the access strategy field vs property access.
In the previous project, everything was with property-based access, but after I have added lombok the class Language was field-based access.
The class LanguagePK was
public class LanguagePK implements Serializable {
private static final long serialVersionUID = 1L;
private int personId;
private int position;
private String languageNameVal;
#Column(name = "person_id")
#Id
public int getPersonId() {
return personId;
}
public void setPersonId(int personId) {
this.personId = personId;
}
#Column(name = "position")
#Id
public int getPosition() {
return position;
}
public void setPosition(int position) {
this.position = position;
}
#Column(name = "language_name")
#Id
public String getLanguageNameVal() {
return languageNameVal;
}
public void setLanguageNameVal(String languageNameVal) {
this.languageNameVal = languageNameVal;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
LanguagePK that = (LanguagePK) o;
if (personId != that.personId) return false;
if (position != that.position) return false;
if (languageNameVal != null ? !languageNameVal.equals(that.languageNameVal) : that.languageNameVal != null)
return false;
return true;
}
#Override
public int hashCode() {
int result = personId;
result = 31 * result + position;
result = 31 * result + (languageNameVal != null ? languageNameVal.hashCode() : 0);
return result;
}
}
It's enough and works
#EqualsAndHashCode
public class EducationPK implements Serializable {
private int personId;
private int position;
}

According to the database I am getting expected master child data like below
After designing this entity class I am expecting that I will get 3 master records where each record has 2 detail records. But I am getting 6 duplicate master records with 12 child records. Can anyone suggest to me please where is my code became wrong and why this situation raised? please check the JSON data that I am getting from API.
change your array list to hash set then records are not duplicate.
I am trying to dynamicaly create a Specification for my Spring-data-jpa project
Here is my specification for the moment:
public class DemandsSpecs implements Specification<SvDem> {
private static final Logger LOG = LogManager.getLogger();
private final DemandsCritera critera;
private final List<Predicate> predicateList;
public DemandsSpecs(final DemandsCritera critera) {
this.critera = critera;
this.predicateList = new ArrayList<>();
}
#Override
public Predicate toPredicate(final Root<SvDem> root,
final CriteriaQuery<?> query,
final CriteriaBuilder cb) {
this.predicateList.add(cb.between(root.get(SvDem_.hdCreation), critera.getBegin(), critera.getEnd()));
if (critera.getSoc() != null) {
LOG.debug("socId {}", critera.getSoc());
this.predicateList.add(cb.equal(root.get(SvDem_.socId), critera.getSoc()));
}
if (critera.getManagementAct() != null) {
LOG.debug("actgesId {}", critera.getManagementAct());
this.predicateList.add(cb.equal(root.get(SvDem_.actgesId), critera.getManagementAct()));
}
if (critera.getStatus() != null) {
LOG.debug("statutId {}", critera.getStatus());
this.predicateList.add(cb.equal(root.get(SvDem_.statutId), critera.getStatus()));
}
if (!StringUtils.isBlank(critera.getId())) {
LOG.debug("id {}", critera.getId());
this.predicateList.add(cb.like(root.get(SvDem_.id), '%' + critera.getId() + '%'));
}
return query.where(cb.and(predicateList.toArray(new Predicate[predicateList.size()])))
.orderBy(cb.desc(root.get("hdCreation")))
.getRestriction();
}
}
The DemandsCritera also have a String property metadata.
public class DemandsCritera implements Serializable {
private static final Long serialVersionUID = 1L;
private Date begin;
private Date end;
private RfActges managementAct;
private String metadata;
private RfStatut status;
private RfSoc soc;
private String id;
/* getters and setters */
}
SvDem has a property svMetaCollection which is a Collection<SvMeta>.
#Entity
#Table(name = "sv_dem")
public class SvDem implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
private String id;
#Basic(optional = false)
#Column(name = "HD_CREATION")
#Temporal(TemporalType.TIMESTAMP)
private Date hdCreation;
#Lob
private String user;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "svDem")
#JsonManagedReference
private Collection<SvMeta> svMetaCollection;
#JoinColumn(name = "ACTGES_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfActges actgesId;
#JoinColumn(name = "STATUT_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfStatut statutId;
#JoinColumn(name = "SOC_ID", referencedColumnName = "ID")
#ManyToOne(optional = false)
private RfSoc socId;
/* getters, setters and other irrelevant properties */
}
The SvMeta object has a String property value
#Entity
#Table(name = "sv_meta")
public class SvMeta implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
protected SvMetaPK svMetaPK;
#Basic(optional = false)
#Lob
private String value;
#JoinColumn(name = "META_ID", referencedColumnName = "ID", insertable = false, updatable = false)
#ManyToOne(optional = false)
private RfMeta rfMeta;
#JoinColumn(name = "DEM_ID", referencedColumnName = "ID", insertable = false, updatable = false)
#ManyToOne(optional = false)
#JsonBackReference
private SvDem svDem;
}
I want to return all the SvDem where any of its SvMeta has a value equals to the DemandsCritera.metadata.
How can I achieve that?
I just needed to add this to my toPredicate method of DemandsSpecs:
if (!StringUtils.isBlank(critera.getMetadata())) {
LOG.debug("metadata {}", critera.getMetadata());
Join<SvDem, SvMeta> metas = root.join(SvDem_.svMetaCollection);
this.predicateList.add(cb.equal(metas.get(SvMeta_.value), critera.getMetadata()));
}
I try to gather statistics of visitors for two services. It consists of daily visitors statistics and overall record. Each service can be accessed by different names. For example, user, admin, support etc. Each will have its own record as own statistics.
Here is my DB structure:
service_one: id, name
service_two: id, name
daily_stats: id, date, service_one_id, service_one_visitors,
service_two_id, service_two_visitors, overall_visitors
record_stats: id, service_one_id, service_one_record,
service_one_record_date, service_two_id, service_two_record,
service_two_record_date
Here are the relations between tables:
service_one --- (one to many) ---> daily_stats(service_one_id)
service_one --- (one to many) ---> record_stats(service_one_id)
service_two --- (one to many) ---> daily_stats(service_two_id)
service_two --- (one to many) ---> record_stats(service_two_id)
Mapping for service_one (the same is for service_two). Also setters were omitted in order to shorten the example:
#Entity
#Table(name = "service_one")
public class ServiceOne implements Serializable {
private int id;

private Set<RecordStats> recordStats = new HashSet<RecordStats>(0);

org.hibernate.MappingException: Repeated column in mapping for entity:
VisitorsCounter.model.entity.DailyStats column: id (should be
mapped with insert="false" update="false")
What is wrong with my mapping?
It seems to me that
#JoinColumn(name = "id", nullable = false)
public ServiceOne getService_one_id() {
return service_one_id;
}
in DailyStats is wrong; you should have name = "service_one_id".
You have the same problem in getService_two_id() and in methods of same names in RecordStats.
May I also ask why don't you name the references in the classes fields serviceOne and serviceTwo instead of service_one_id and service_two_id.
