i'm new here^^
i'm working with a db in which boolean are registered as VARCHAR(3) So i made a converter :
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;
#Converter
public class BooleanToStringConverter implements
AttributeConverter<Boolean, String> {
#Override
public String convertToDatabaseColumn(Boolean value) {
if (value == null)
return "";
else if (value)
return "OUI";
else
return "NON";
}
#Override
public Boolean convertToEntityAttribute(String value) {
if (value == null)
return null;
else if (value.trim().equals("OUI"))
return true;
else if (value.trim().equals("NON"))
return false;
else if (value.trim().equals(""))
return null;
else
throw new IllegalStateException("Invalid boolean character: "
+ value);
}
}
i put my annotations #Convert:
public class Institution extends AbstractHREntity {
#Column(name = "IDOU00")
private String code;
#Column(table = "ZEXX", name = "LBOULG")
private String libelle;
#Column(table = "ZEXX", name = "LBOUSH")
private String abreviation;
#Column(table = "ZEYY", name = "LIBEXL")
private String libelleLong;
#Convert(converter = BooleanToStringConverter.class)
#Column(table = "ZEZZ", name = "ESTBUDGET", length = 3)
private Boolean isBudget;[/CODE]
But when i do a request with a criteria :
public List<Institution> findInstitutions(RechercheInstitutionData datas) throws DaoException{
List<Institution> resultList = new ArrayList<Institution>();
DetachedCriteria criteria = DetachedCriteria.forClass(Institution.class, "institution");
if(null!=datas.getInstitutionSearched())
{
if (StringUtils.isNotBlank(datas.getInstitutionSearched().getLibelleLong())){
criteria.add(Restrictions.like("institution.libelleLong", datas.getInstitutionSearched().getLibelleLong().toUpperCase(), MatchMode.START));
}
if (StringUtils.isNotBlank(datas.getInstitutionSearched().getAbreviation())){
criteria.add(Restrictions.like("institution.abreviation", datas.getInstitutionSearched().getAbreviation().toUpperCase(), MatchMode.START));
}
if (StringUtils.isNotBlank(datas.getInstitutionSearched().getLibelle())){
criteria.add(Restrictions.like("institution.libelle", datas.getInstitutionSearched().getLibelle(), MatchMode.START).ignoreCase());
}
if (StringUtils.isNotBlank(datas.getInstitutionSearched().getCode())){
criteria.add(Restrictions.like("institution.code", datas.getInstitutionSearched().getCode(), MatchMode.START));
}
criteria.addOrder(Order.asc("institution.code"));
}
resultList = find(criteria);
return resultList;
}
i had this error that occurred :

It looks like it doesn't use my converter, i tried breakpoints it doesn't go into my converter... In converter doc it says "all you have to do is put the #convert" but apparently no... Please help i'm really lost.

I have a class hierarchy that is somewhat like below, with a custom Converter
The FieldValueConverter#deserialize is NOT being called in my JerseyTest. Instead, it uses the default GensonJsonConverter which complains it can't find the appropriate constructor. (Caused by: com.owlike.genson.JsonBindingException: No constructor has been found for type class com.searchdata.actions.api.FieldValue)
How do I get it to be used?
Registration
The converter for the FieldValues (see below), which I register in a Jersey Application like this:
Genson genson = new GensonBuilder()
.withBundle(new JAXBBundle())
.withConverter(new FieldValueConverter(), FieldValue.class)
.setSkipNull(true)
.create();
register(new GensonJaxRSFeature().use(genson));

public class FieldValueConverter implements Converter<FieldValue> {
private static final Logger LOG = LoggerFactory.getLogger(FieldValueConverter.class);
public void serialize(FieldValue fieldValue, ObjectWriter writer, Context ctx) throws Exception {
LOG.info("Serializing fieldValue:{}", fieldValue);
writer.beginObject();
writer.writeString("type", fieldValue.getType().name())
.writeString("value", fieldValue.getValue().toString())
.writeString("field", fieldValue.getField());
writer.endObject();
LOG.info("..Done!", fieldValue);
}
/* You don't have to worry for the object being null here, if it is null Genson will
handle it for you. */
public FieldValue deserialize(ObjectReader reader, Context ctx) throws Exception {
LOG.info("Deserializing fieldValue...");
reader.beginObject();
String stringValue=null;
FieldType type= FieldType.STRING;
String fieldKey= null;
while (reader.hasNext()) {
reader.next();
if ("type".equals(reader.name())) {
type = FieldType.valueOf(reader.valueAsString());
} else if ("field".equals(reader.name())) {

I have a case where I need to execute an insert statement via createNativeQuery. I have an entity list I'm looping through in order to set the properties accordingly from another bean class, and then persist that data to the oracle database.
The problem I am facing is persisting the data that is part of the embeddedId (item, loc, weekstart, type, forecastId, insertTS). I need to persist that data for the new records to be inserted into the database. When I try to set the values from the POJO bean to my set method for the properties of my entity bean, nothing happens. Below is my code for setting the values of the properties from the POJO bean to my entity bean, along with my persistence method and the insert query being executed:
Validation class where validation occurs beforehand (missing to get the point) that includes the setting of my entity properties from the POJO bean:
List <InsertPromoData> insertPromos = new ArrayList<InsertPromoData>();
promo.forEach(record -> {
if (record.getErrorList().size() == 0) {
rowsSuccessful++;
Util.writeSuccessToFile(templateCd, successFile, record, successFields);
try {
InsertPromoData insertData = new InsertPromoData();
insertData.getId().setItem(record.getItem());
insertData.getId().setLoc(record.getLoc());
insertData.getId().setWeekStart(record.getWeek_Start_Date());
insertData.setNumberOfWeeks(record.getNumber_Of_Weeks());
insertData.getId().setType(record.getType());
insertData.getId().setForecastId(record.getForecast_ID());
insertData.setQty(record.getUnits());
insertPromos.add(insertData);
}
catch (Exception e) {
logger.error("Error with setting insertPromolist from promo list values and the error is " + e.getMessage());
}
}
else {
if (rowsFailure == 0) {
Util.writeHeaderToFile(templateCd, errorFile);
}
rowsFailure++;
Util.writeErrorToFile(templateCd, errorFile, record, record.getErrorList());
}
});
errorFile.close();
successFile.close();
OracleImpl.insertPromoData(insertPromos);
POJO bean (promo is the variable representing this list of beans in validation class above):
public class PromoBean extends ErrorListBean
{
public String Item;
public String Loc;
public String Week_Start_Date;
public String Units;
public String Forecast_ID;

Query in properties file:

My list size from my DAO class is returning as 0 once I begin the transaction and not sure why it is empty. Is there a reason that it is empty? I'm trying to persist each of the fields to the database (including the composite key fields) via insert query. Any help appreciated.
After looking into this for hours, I finally came to the conclusion that the simplest way to executeUpdate() without running into issues due to my current #EmbeddedId/#Embeddable logic was to change it to use #IdClass for my composite PK class, and annotate the fields from the PK in my entity with #Id. This allowed my data to be persisted to the database. Another slight difference was adding the insertTS in my entity class and annotating with #Id and generating getters/setters. This was necessary for JPA to recognize all the properties being referenced that I am wanting to persist, though I am persisting insertTS using SYSDATE function from the oracle DB instead of utilizing the get/set methods and setting to the current time from the java side.
I am sure there is a way to use #EmbeddedId/#Embeddable logic and be able to persist the fields that are part of the EmbeddedId, however, this I found to be a more simplistic way of doing it without further complexity in the code.
Trying to achieve
fetch all the data from main table and all the corresponding child record with activeYn != N.
This is parent entity
#Entity
#Table(name="IR_TB_INCIDENT_HDR")
public class IncidentHdr implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#SequenceGenerator(name="IR_TB_INCIDENT_HDR_INCIDENTID_GENERATOR", sequenceName="IR_SEQ_INCIDENT_ID",allocationSize=1)

#Column(name="PATIENT_ID")
private Long patientId;
#OneToMany(cascade = {CascadeType.PERSIST,CascadeType.MERGE, CascadeType.REMOVE}, fetch = FetchType.LAZY, mappedBy="incidentHdr")
private Set<Attachments> attachments;
....
//other child entities
}
This is the child entity
#Entity
#Table(name="IR_TB_ATTACHMENTS")
public class Attachments implements Serializable {
private Long attachmentId;
private IncidentHdr incidentHdr;
private boolean activeYn;
}
Here we are genegating the custom query, we are appending only one condition here.
public IncidentHdr findIncidentDetailForId(Long incidentId) throws BusinessException {
StringBuilder query = null;
IncidentHdr incidentHdr = null;
StringBuilder incidentDetailQuery = null;
Query q = null;
Map < String, Object > parameters = new HashMap < String, Object > ();
List < String > criteria = new ArrayList < String > ();
try {
incidentDetailQuery = new StringBuilder();
query = new StringBuilder();
query.append(ReposJPQL.GET_INCIDENTS_DETAIL);
criteria.add("inc.incidentId = :incidentId ");
parameters.put("incidentId", incidentId);
if (criteria.size() > 0) {
for (int i = 0; i < criteria.size(); i++) {
incidentDetailQuery.append(" AND ");
incidentDetailQuery.append(criteria.get(i));
}
}
query.append(incidentDetailQuery);
q = em.createQuery(query.toString());
for (Entry < String, Object > entry: parameters.entrySet()) {
q.setParameter(entry.getKey(), entry.getValue());
}
incidentHdr = (IncidentHdr) q.getSingleResult();
}catch(IllegalArgumentException | IllegalStateException | DataAccessException | EntityNotFoundException e) {
logger.error(e.getMessage());
throw new BusinessException(e);
}
return incidentHdr;
}
ReposJPQL, Here defined the query with activeYn condition.
public interface ReposJPQL {
public String GET_INCIDENTS_DETAIL = "SELECT inc "
+ " FROM IncidentHdr inc left join inc.attachments att WHERE att.activeYn <> 'N' ";
}
Even though the records are present it return "org.springframework.dao.EmptyResultDataAccessException: No entity found for query; nested exception is javax.persistence.NoResultException: No entity found for query"
error
Or is there any other way to achieve this ? #Where(clause=...) option is pure hibernate so cant use that.
I am facing two issues here :
Issue 1) I am trying to get the COMPANY_ID using the selectCompanyID variable as shown below. I am storing the value returned into getCompanyID variable.When I tried to print it, as shown in the console output below, it's always printing number 1. However, when I tried to run the actual SQL in the
Oracle SQL developer SQL Worksheeet, I got different number. Because of this I could insert wrong ID in the following INSERT statement where it's
getting used.
Issue 2) As shown in the SQL, I am also getting ORA-00984: column not allowed here error. Noticed, people encountering similar error in the following post :
"column not allowed here" error in INSERT statement
But here I don't have straightforward SQL INSERT statement as the one mentioned in the above post with missing quotes.

My Domain class Stock has five attributes. (stockId,stockCode,StockName,Status , Stock
Description)
I need to declare the field Stock description as Composite field Type.
private Integer stockId;
private String stockCode;
private String stockName;
private String status;
private String stockDescription;
//Constructors
#Column(name = "STOCK_CC", unique = true, nullable = false, length = 20)
#Type(type="com.mycheck.EncryptedAsStringType")
#Columns(columns = { #Column(name="STOCK_ID"),
#Column(name="STOCK_CODE"),
#Column(name="STOCK_NAME")
})
public String getStockDescription() {
return stockDescription;
}
}
When I try to execute a insert for Stock. I am getting the error Error creating bean with name
'sessionFactory' defined in class path resource [spring/config/../database/Hibernate.xml]:
Invocation of init method failed. nested exception is org.hibernate.MappingException:
property mapping has wrong number of columns: com.stock.model.Stock.stockDescription type:
com.mycheck.EncryptedAsStringType
Where am I going wrong ?
One can extract the answer from the code samples and the comments to the original question, but to save everyone some reading, I've compiled a quick summary.
If you declare a CompositeUserType that maps a type to n columns, you have to declare n columns in #Columns besides the #Type annotation. Example:
public class EncryptedAsStringType implements CompositeUserType {
#Override
public String[] getPropertyNames() {

This CompositeUserType maps to 4 separate columns, therefore 4 separate #Column annotations have to be declared:
#Type(type="com.mycheck.EncryptedAsStringType")
#Columns(columns = {
#Column(name="STOCK_ID"),
#Column(name="STOCK_CODE"),
#Column(name="STOCK_NAME"),
#Column(name="STOCK_DESCRIPTION")
})
public String getStockDescription() {
return stockDescription;
}
That's it and Hibernate is happy.
