org.hibernate.MappingException: Could not determine type for: java.util.List for Hierarchy Ref Cursor function result

I'm trying to call a procedure function in DB and to mapped the Hierarchy answer to entity class using hibernate.The entities that I wrote suppose to represent the result structure that is returned from a ref cursor function.
The result of the function has a property which is a list of objects and inside that object there is also a property that is also a list of another objects.
On application startup I get the MappingException as I wrote in the title above.
I tried to add the annotation #OneToMany but it is not working because it is not looking at tables in DB.
Again, the entities represent the function result and not select from table tables.
Someone has any idea of any annotation that could prevent from this exeception to araise in the application startup?
My Entities:
Main Entity that call to procedure function (rc):

ERROR org.hibernate.engine.jdbc.spi.SqlExceptionHelper [http-nio-8080-exec-3] (logExceptions:131) [] - The column name is not valid

trying to run a native query however I'm getting The column name sb_modelid is not valid. when attempting to map the return object to my model object in java? I have verified all the column names are correct.
1) Why is it referring to my column name as sb_modelid and not sbModelID?
2) Why is not being mapped to my POJO correctly?
Thanks!

Well, on Metamodels there are basically three approaches to use:
Using IDE based metamodel generation tools
Using Static Canonical Metamodel Classes
Using em.getMetamodel() API i.e. the one you are using.
The solution I am proposing for you to use which is closer to what you were doing is on Point 3.
Point 3 Solution :
Replace the below code :
Metamodel m = em.getMetamodel();
EntityType<Notificacao> Notificacao_ = m.entity(Notificacao.class);
Root<Notificacao> myObj = cq.from(Notificacao_);
Join<Notificacao, Fonte> fontes = myObj.join(Notificacao_.fonte); // HERE I'M GETTING THE ERROR
With new code :
Metamodel m = em.getMetamodel();
EntityType<Notificacao> notificacao_ = m.entity(Notificacao.class);
Root<Notificacao> myObj = cq.from(notificacao_);
Join<Notificacao, Fonte> fontes = myObj.join(notificacao_.getSingularAttribute("fonte",Fonte.class));
Points 1 & 2 Solutions
Please note the Notificacao_ must be a class either static or generated and must never be an instance of em.getMetamodel(). Also note in your case before Notificacao_ was a variable instead of a class as shown:
EntityType<Notificacao> Notificacao_ = m.entity(Notificacao.class);
If you need more info, let me know please.

GET transient field with zero int value in java spring data

We're making get requests through a controller. The model contains transient fields that are set in the controller. Only int fields that are not null or >0 are being returned by the controller. How can I allow a transient field to return a 0 value, as this is meaningful. In this case the transient fields are 'sentenceStart' and 'sentenceEnd'.
Controller:
#RequestMapping(value = "/{match_id}", method = RequestMethod.GET)
public Match getMatch(#PathVariable("match_id") long matchId) {
long start = System.currentTimeMillis();
LOGGER.info("REQUESTED RETRIEVAL OF MATCH WITH ID: " + matchId);
Match match = matchRepository.findOneById(matchId);
match.setActualText(matchRepository.getText(match.getId()));
match.setSentenceStart(matchRepository.getSentenceStart(match.getId()));
match.setSentenceEnd(matchRepository.getSentenceEnd(match.getId()));
match.setSentenceID(matchRepository.getSentenceId(match.getId()));
long end = System.currentTimeMillis();
LOGGER.info("DONE. TOOK " + (end - start) + " MILLISECONDS.");
return match;
} //getMatch()
Repository:
public interface MatchRepository extends JpaRepository<Match, Long>, JpaSpecificationExecutor<Match> {
#Query(value = "SELECT match_in_sentence_start FROM vTextMatch where match_id = :m_id LIMIT 1",
nativeQuery = true)
int getSentenceStart(#Param("m_id") long matchId);
#Query(value = "SELECT match_in_sentence_end FROM vTextMatch where match_id = :m_id LIMIT 1",
nativeQuery = true)
int getSentenceEnd(#Param("m_id") long matchId);
}
Model:
#Entity
#Table(name = "match_term")
#JsonInclude(JsonInclude.Include.NON_EMPTY)
public class Match {
#Id
#GeneratedValue
#Column(name = "match_id", nullable = false)
private Long id;
#Column(name = "document_id", nullable = false)
private Long documentId;
#Column(name = "document_start")
private Integer documentStart;
#Column(name = "document_end")
private Integer documentEnd;
#Column(name = "is_meta", nullable = false)
private Boolean isMeta;
#Column(name = "date_inserted", nullable = false)
private Timestamp dateInserted;
#Transient
private String actualText;
#Transient
private int sentenceStart;
#Transient
private int sentenceEnd;
#Transient
private int sentenceID;

public int getSentenceStart() {
return sentenceStart;
}
public void setSentenceStart(int sentenceStart) {
this.sentenceStart = sentenceStart;
}
public int getSentenceEnd() {
return sentenceEnd;
}
public void setSentenceEnd(int sentenceEnd) {
this.sentenceEnd = sentenceEnd;
}
}

You should investigate line containing #JsonInclude(JsonInclude.Include.NON_EMPTY) - http://fasterxml.github.io/jackson-annotations/javadoc/2.0.0/com/fasterxml/jackson/annotation/JsonInclude.Include.html#NON_EMPTY
I would suggest slightly change your design and introduce some message type. You could avoid polluting your domain class with the not needed stuff.

Spring Data JPA date "between" query issue when using Date parameters

In my application, I am using Spring Data and hibernate as JPA provider to persist and read data.
I have top level Entity class:
#Entity
#Getter #Setter
#Table(name = "operation")
#Inheritance(strategy = InheritanceType.JOINED)
#EqualsAndHashCode(of = {"operationId"})
public abstract class Operation implements Serializable {
public static final int OPERATION_ID_LENGTH = 20;
#Id
#Column(name = "operation_id", length = OPERATION_ID_LENGTH, nullable = false, columnDefinition = "char")
private String operationId;
#Column(name = "operation_type_code")
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private String operationTypeCode;
#Temporal(TemporalType.TIMESTAMP)
#Column(name = "begin_timestamp", nullable = false)
private Date beginTimestamp = new Date();
#Temporal(TemporalType.TIMESTAMP)
#Column(name = "end_timestamp")
private Date endTimestamp;
#Column(name = "operation_number", length = 6, columnDefinition = "char")
private String operationNumber;
#Enumerated(EnumType.STRING)
#Column(name = "operation_status", length = 32, nullable = false)
private OperationStatus status;
#ManyToOne(optional = false)
#JoinColumn(name = "user_id")
private User user;
#ManyToOne
#JoinColumn(name = "terminal_id")
private Terminal terminal;
#Column(name = "training_mode", nullable = false)
private boolean trainingMode;
}
For inherited class I have corresponding repository:
public interface ConcreteOperationRepository extends JpaRepository<ConcreteOperation, String> {
#Query("SELECT o FROM ConcreteOperation o WHERE o.beginTimestamp BETWEEN :from AND :to AND o.status = :status AND o.terminal.deviceId = :deviceId AND o.trainingMode = :trainingMode")
Collection<ConcreteOperation> findOperations(#Param("from") Date startDay,
#Param("to") Date endDay,
#Param("status") OperationStatus status,
#Param("deviceId") String deviceId,
#Param("trainingMode") boolean trainingMode);
}
And I have integration test with following method:
#Transactional
#Test
public void shouldFindOperationByPeriodAndStatusAndWorkstationId() {
Date from = new Date(Calendar.getInstance().getTime().getTime());
List<String> terminalIds = loadTerminalIds();
List<OperationStatus> typeForUse = Arrays.asList(OperationStatus.COMPLETED,
OperationStatus.LOCKED, OperationStatus.OPEN);
int countRowsForEachType = 3;
int id = 100001;
for (String terminalId : terminalIds) {
for (OperationStatus status : typeForUse) {
for (int i = 0; i < countRowsForEachType; i++) {
concreteOperationRepository.save(createConcreteOperation(status, terminalId,
String.valueOf(++id)));
}
}
}
Date to = new Date(Calendar.getInstance().getTime().getTime());
for (String terminalId : terminalIds) {
for (OperationStatus status : typeForUse) {
Collection<ConcreteOperation> operations =
concreteOperationRepository.findOperations(from, to, status, terminalId, false);
assertEquals(countRowsForEachType, operations.size());
}
}
}
But this test fails when I using MySql database due to empty result (but passes when I switch to HSQLDB)
Also, this test passes if I put delay "Thread.sleep(1000)" for one second at the beginning of the test, just after the first line.
When I execute SQL from Hibernate log it gives me right result. What's wrong with my code?

In JPA, the Date requires a temporal hint. Normally, you could set the TemporalType when setting the JPA Query parameter:
query.setParameter("from", from), TemporalType.TIMESTAMP);
With Spring Data you need to use the #Temporal annotation, so your query becomes:
#Query("SELECT o FROM ConcreteOperation o WHERE o.beginTimestamp BETWEEN :from AND :to AND o.status = :status AND o.terminal.deviceId = :deviceId AND o.trainingMode = :trainingMode")
Collection<ConcreteOperation> findOperations(
#Param("from") #Temporal(TemporalType.TIMESTAMP) Date startDay,
#Param("to") #Temporal(TemporalType.TIMESTAMP) Date endDay,
#Param("status") OperationStatus status,
#Param("deviceId") String deviceId,
#Param("trainingMode") boolean trainingMode
);

I realized my problem. The problem was due to difference of precision between type of field in MySql (default timestamp precision cut of milliseconds) and Java date (with milliseconds)
I've altered my table:
ALTER TABLE transaction modify end_timestamp TIMESTAMP(6)
and that's solved my problem.
