I created my app using JHipster. When i try to get list of tournaments via TournamentQueryService i get this error :
Exception in TournamentQueryService.findByCriteria() with cause =
'org.hibernate.HibernateException: Unable to access lob stream' and
exception = 'Unable to access lob stream; nested exception is
org.hibernate.HibernateException: Unable to access lob stream'
This is filter and Page object :
find by criteria : TournamentCriteria{}, page: Page request [number:
0, size 8, sort: startDate: DESC]
So it just gets 8 first tournaments.
This is tournament class :
#Entity
#Table(name = "tournament")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
#Document(indexName = "tournament")
public class Tournament extends AbstractAuditingEntity implements Serializable {
private static final long serialVersionUID = 1L;

Here is the method that calls hibernate :
#Transactional(readOnly = true)
public Page<Tournament> findByCriteria(TournamentCriteria criteria, Pageable page) {
log.info("find by criteria : {}, page: {}", criteria, page);
final Specifications<Tournament> specification = createSpecification(criteria);
Page<Tournament> result = tournamentRepository.findAll(specification, page);
return result;
}
Is it possibile that you are trying to access Lob properties when hiberante session is closed?
Try to replace your #Lob properties with the following:
#Basic(fetch=FetchType.EAGER) #Lob
and check if the error persists.

I have some entity classes and i have a question because I want to clear it in my mind. In case of #ManyToOne relationship where I insert for example #JoinColumn(name = "cardHolderId"), shall I remove the primitive private Long cardHolderId? Because I had a discussion and a programmer explained to me that I can avoid declaring. But if I avoid it I can not use it in test cases like services.
#Entity
#Getter
#Setter
#Builder
#NoArgsConstructor
#AllArgsConstructor
#Table(name = "card")
public class Card {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#Column(name = "code")
private String code;
#Column(name = "number")
private String number;
#Column(name = "issueDate")
private Date issueDate;
#Column(name = "expireDate")
private Date expireDate;
#Column(name = "elasticDate")
private Date elasticDate;
#Column(name = "pin")
private Long pin;
#Column(name = "isValid")
private Boolean isValid;
#Column(name = "isUsed")
private Boolean isUsed;
#Column(name = "isPin")
private Boolean isPin;
#Column(name = "cardCategoryId")
private Long cardCategoryId;
#Column(name = "hasNumberOfVisits")
private Boolean hasNumberOfVisits;
#Column(name = "numberOfVisits")
private Long numberOfVisits;
#Column(name = "isBlackListed")
private Boolean isBlackListed;
#Column(name = "cardHolderId")
private Long cardHolderId;
//Check Relationships
#ManyToOne
#JoinColumn(name = "cardCategoryId")
private CardCategory cardCategory;

private CardHolder cardHolder;
#Column(name = "companyGroupId")
private Long companyGroupId;
#ManyToOne
#JoinColumn(name = "companyGroupId")
private CompanyGroup companyGroup;
#OneToMany(mappedBy = "card")
private List<AccessControlSubject> accessControlSubjects = new ArrayList<>();
#OneToMany(mappedBy = "card")
private List<Card2Role> card2Roles = new ArrayList<>();
#ManyToOne
#JoinColumn(name = "cardHistoryId")
private CardHistory cardHistory;
#OneToMany(mappedBy = "vehicleCard")
private List<Vehicle> vehicles = new ArrayList<>();
#ManyToOne
#JoinColumn(name = "sharedCardId")
private PatrolSharedCard sharedCard;
#ManyToOne
#JoinColumn(name = "productionWorkId")
private PrdWork productionWork;
#ManyToOne
#JoinColumn(name = "productionWorkHitsId")
private PrdWorkHits productionWorkHits;
#OneToMany(mappedBy = "card")
private List<VisitorCardHistory> visitorCardHistories = new ArrayList<>();
You can remove it and use the id from the referred entity :
this.getCardHolder().getId()
I am trying to get Order[] Array which includes all Orders where the associated document isn't received.
I tried this query and it returns the right number of rows.
#Query("Select o FROM Order o INNER JOIN o.properties p INNER JOIN p.documents d WHERE d.received = false")
Order[] findUnreceivedOrders();
The problem is, the order objects in my array includes ALL documents not only the unreceived, but I want that the object only includes the unreceived document objects.
Does anyone know how to solve this?
Thanks for help!

Probably you can map #ManyToOne Order to your Document entity and after use for Order entity
#JoinColumnOrFormula(formula = #JoinFormula("(select d.id from documents d WHERE d.order_id = id AND d.received = false"))
List<Document> unreceivedDocuments;
U have list of Property in Order and list of Document in Property. So if u have one Document with status not received in your list u will have this Order.
Thanks to #pdem !
Used "join fetch", changed my lists to sets and it works fine.
I have Many-To-Many relation in my project, i can write in my two Entities table, the relational table does not get anything written.

List<Episodio> listaE = new ArrayList<>();
listaE.add(episodio);
ee.setEpisodioList(listaE);
episodioDao.registrarEpisodio(episodio);
System.exit(0);
}
when doing the persistence in the entities the information is saved automatically, but in the table third table it does not insert the primary keys.
I have added CascadeType.ALL on Episodio as it is the owner of this relation.
Following code may help you. I have tested with spring data jpa.

I am trying to parse a web request and save to database. I have 3 models and first node is virtualDocument. This is the uniq table (according to request url). VirtualRequest table has all erquest bodies and HttpHeaderList table has all thhp headers according to their virtualRequest bean id.
when I tried to save the first log I got and error like this;
org.h2.jdbc.JdbcSQLException: Referential integrity constraint violation: "FK1TW2G47F7A47580KQVMDJWGBQ: PUBLIC.T_VIRTUAL_REQUEST FOREIGN KEY(REQUEST_ID) REFERENCES PUBLIC.T_VIRTUAL_DOCUMENT(DOCUMENT_ID) (65)"; SQL statement:

here is VirtualDocument bean

public class VirtualDocument {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "document_id")
private long documentId;
#Column(name = "real_url", unique = true)

}
I think this is what you want instead:
#Entity
#Table(name = "t_virtual_document")
public class VirtualDocument {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "document_id")
private long documentId;
#Column(name = "real_url", unique = true)

#Column(name = "virtual_url", unique = true)
private String virtualURL; //uniq
#Column(name = "simulation_mode", columnDefinition = "varchar(10) default 'STOP'")
private String simulationMode;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "virtualDocument")
private List<VirtualRequest> requestList;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "virtualDocument")
// Note the mappedBy parameter. This points to the property in the entity that owns the relationship (in this case the VirtualResponse).
private List<VirtualResponse> responseList;
//getter setter without any annotation
}
#Entity
#Table(name = "t_virtual_request")
public class VirtualRequest {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "request_id")
private long requestId;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "document_id")
private VirtualDocument virtualDocument;
#Column(name = "request_url")
private String requestURL;
#Column(name = "method_type")
private String methodType;
#Column(name = "media_type")
private String mediaType;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "virtualRequest")
private List<HttpHeaderList> requestHeaders;
//getter setter without any annotation
}
#Entity
#Table(name = "t_http_headers")
public class HttpHeader { /*Note this is a more appropriate name for the entity since it holds the data of a single header.*/
#Id
#Column(name = "header_id")
private long headerId;
#Column(name = "header_key")
private String headerKey;
#Column(name = "header_value")
private String headerValue;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "request_id")
private VirtualRequest virtualRequest
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "response_id")
private VirtualResponse virtualResponse;
}
Updated the answer to add mapping the headers to the request entity.

Based on above entity design, when I try to persist an 'Employee', I'm getting bellow exception. Any thought?
Caused by: java.lang.ClassCastException: org.hibernate.mapping.SimpleValue cannot be cast to org.hibernate.mapping.Component
I think your problem in mapped by in Employee entity
can you please try using
#OneToMany(cascade = CascadeType.ALL, mappedBy = "employee")
private Set<EmployeeProject> employeeProject;
instead of
#OneToMany(cascade = CascadeType.ALL, mappedBy = "id.employee")
private Set<EmployeeProject> employeeProject;
Also try to change it too in Project entity and use
#OneToMany(cascade = CascadeType.ALL, mappedBy = "project")
private Set<EmployeeProject> employeeProject;
instead of
#OneToMany(cascade = CascadeType.ALL, mappedBy = "id.project")
private Set<EmployeeProject> employeeProject;
So finally you should replace
mappedBy = "id.project" by mappedBy = "project"
AND
mappedBy = "id.employee" by mappedBy = "employee"
