Composite Key - Hibernate

Composite Key - Hibernate - java

I have a table GROCERY which has following structure:
CREATE TABLE grocery
(
gro_id NUMBER,
gro_name VARCHAR(32),
gro_dep_name VARCHAR(32),
gro_price NUMBER(16, 2),
gro_max_discount NUMBER(16, 2),
CONSTRAINT gro_pk PRIMARY KEY (gro_id, gro_dep_name)
)
My problem is that, when I am trying to fetch the data from the table (saved in my oracle data base) , I am getting the following error :
org.hibernate.id.IdentifierGenerationException: null id generated
for:class com.domain.Grocery
I have generated following entity classes according to the structure of the table :

}
I have followed this example.
Please help me out, I am not able to figure out what is wrong in it.
Following is my service to take the data from database, which has GroceryRepository which extends CrudRepository :
#Service
public class GroceryService {
#Autowired
GroceryRepository groceryRepository;
public List<Grocery> getAllGrocery()
{
List<Grocery> groceries = new ArrayList<>();
groceryRepository.findAll().forEach(groceries::add);
return groceries;
}
public void addGrocery(Grocery grocery)
{
groceryRepository.save(grocery);
}
}

Missed #EmbeddedId annotation in Grocery.java. Update your code as below.
#EmbeddedId
private GroceryId id;

Just use #EmbeddedId.There must be only one EmbeddedId annotation and no Id annotation when the EmbeddedId annotation is used.
#EmbeddedId
private GroceryId id;

How to resolve Quarkus Hibernate insert SQLGrammerException

My configuration is the same as the Quarkus guide. I can now query from my database, but trying to insert produces this exception. I am VERY experienced in JPA using Eclipselink, so I know my Entity class is not the problem, as I can query the database with it using a standard JPQL syntax.
The insert fails on a simple em.persist(entity).
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not insert
Caused by: org.postgresql.util.PSQLException: Unsupported Types value: 1,426,407,511

Well, I resolved my own problem, simpler than I expected.
I changed my usage of PostresUuidConverter to #Type(type = "pg-uuid") and all works now.

The image is format BASE64, but throws me the following error:
javax.servlet.ServletException: Exception [EclipseLink-6065] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.QueryException

as it should send the form? Thanks

I just needed to remove the brackets , remove the GlassFish default has netbeans , delete all records and install a new one.
So I stick to insert the image into base64 to database

Since you used an embeddable type (CompositionPK) as your primary key for Composition entity, you should annotate the corresponding primary key field in your Composition entity with #EmbeddedId.
#EmbeddedId
private CompensationPK compensationPK;
On the Focus entity, you need not specify a #PrimaryKeyJoinColumn on the one-to-one mapping. It will just use the default join column names for the foreign keys.
So this code should be fine without the #PrimaryKeyJoinColumn:
#OneToOne
public Compensation getCompensation() {
return compensation;
}
This is a sample Hibernate generated schema based on your mappings (target DB is MySQL):
Hibernate:
create table CT_FOCUS (
FOCUS_ID integer not null,
FOCUS_DESC varchar(16),
FOCUS_YN varchar(1),
compensation_COMMISSION_MONTH integer,
compensation_COMMISSION_YEAR integer,
compensation_DIVISION_ID varchar(255),
compensation_FOCUS_ID integer,
compensation_REP_ID varchar(255),
compensation_REPTYPE_ID integer,
primary key (FOCUS_ID)
)
Hibernate:
create table commissions (
COMMISSION_MONTH integer not null,
COMMISSION_YEAR integer not null,
DIVISION_ID varchar(255) not null,
FOCUS_ID integer not null,
REP_ID varchar(255) not null,
REPTYPE_ID integer not null,
LY_MONTHLY_NET_SALES double precision,
TY_MONTHLY_NET_SALES double precision,
TY_YTD_NET_SALES double precision,
primary key (COMMISSION_MONTH, COMMISSION_YEAR, DIVISION_ID, FOCUS_ID, REP_ID, REPTYPE_ID)
)
Hibernate:
alter table CT_FOCUS
add constraint FK_d6d2c9n91dlw59uiuqswfueg5
foreign key (compensation_COMMISSION_MONTH, compensation_COMMISSION_YEAR, compensation_DIVISION_ID, compensation_FOCUS_ID, compensation_REP_ID, compensation_REPTYPE_ID)
references commissions (COMMISSION_MONTH, COMMISSION_YEAR, DIVISION_ID, FOCUS_ID, REP_ID, REPTYPE_ID)
#PrimaryKeyJoinColumn can be used on a #OneToOne mapping, if you want the primary keys of Focus entity to be referencing the primary keys of Commission entity. However, you already have defined a primary key for your Focus entity, which the focusId annotated by #Id. So there's no need to specify a #PrimaryKeyJoinColumn.

Hibernate criteria when using mapped classes

I have created an object which maps two tables in my database, the Dictionary table and the Token table. The object (class) that represents the join between these two tables is called DictionaryToken.
Here is the class:
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import org.apache.log4j.Logger;
#Entity
#Table(name="dictionary", catalog="emscribedxcode")
public class DictionaryToken {
private static Logger LOG = Logger.getLogger(DictionaryToken.class);
private Long _seq;
private String _code;
private String _acute;
private String _gender;
private String _codeType;
private String _papplydate;
private String _capplydate;
private Long _tokenLength;
private List <TokenDictionary> _token;
private int _type;
private String _system;
private String _physicalsystem;
/*
* type of 0 is a straight line insert type of 1 is a language dictionary
* entyr type of 2 is a multiple token entry
*/
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "seq")
public Long getSeq() {
return _seq;
}
public void setSeq(Long seq_) {
_seq = seq_;
}
#Column(name = "code")
public String getCode() {
return _code;
}
public void setCode(String code_) {
_code = code_;
}
#Column(name = "acute")
public String getAcute() {
return _acute;
}
public void setAcute(String acute_) {
_acute = acute_;
}
#Column(name = "gender")
public String getGender() {
return _gender;
}
public void setGender(String gender_) {
_gender = gender_;
}
#Column(name = "codetype")
public String getCodeType() {
return _codeType;
}
public void setCodeType(String codeType_) {
_codeType = codeType_;
}
#Column(name = "papplydate")
public String getPapplydate() {
return _papplydate;
}
public void setPapplydate(String papplydate_) {
_papplydate = papplydate_;
}
#Column(name = "capplydate")
public String getCapplydate() {
return _capplydate;
}
public void setCapplydate(String capplydate_) {
_capplydate = capplydate_;
}
#Column(name = "token_length")
public Long getTokenLength() {
return _tokenLength;
}
public void setTokenLength(Long tokenLength_) {
_tokenLength = tokenLength_;
}
#OneToMany (mappedBy = "dictionarytoken", targetEntity = TokenDictionary.class, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public List<TokenDictionary> get_token() {
return _token;
}
public void set_token(List<TokenDictionary> _token) {
this._token = _token;
}
public void addToToken(TokenDictionary token){
this._token.add(token);
}
#Column(name = "type")
public int getType() {
return _type;
}
public void setType(int _type) {
this._type = _type;
}
#Column(name = "physicalsystem")
public String get_physicalsystem() {
return _physicalsystem;
}
public void set_physicalsystem(String _physicalsystem) {
this._physicalsystem = _physicalsystem;
}
#Column(name = "codingsystem")
public String get_system() {
return _system;
}
public void set_system(String _system) {
this._system = _system;
}
}
Here is my problem. I can perform queries using a service with this object with no problems UNLESS I add a criteria. Here is the method which retrieves the entries
public List<DictionaryToken> getDictionaryTokenEntries(String system) {
Session session = null;
List<DictionaryToken> dictonaries = new ArrayList<DictionaryToken>();
try {
session = HibernateUtils.beginTransaction("emscribedxcode");
session.createCriteria(Dictionary.class).addOrder(Order.desc("codeType"))
Criteria criteria = session.createCriteria(DictionaryToken.class);
/*******THIS IS THE PROBLEM STATEMENT*************************/
if (system != null) {
criteria.add(Restrictions.eq("codingsystem", system));
}
/****************************************************************/
// dictonaries = criteria.list();
Order order = Order.asc("seq");
criteria.addOrder(order);
dictonaries = criteria.list();
System.out.println("Dictionaryentries = " + dictonaries.size());
// System.out.println("Dictionaries entries EVICT start...");
// for(Dictionary dic : dictonaries){
// session.evict(dic);
// }
// System.out.println("Dictionaries entries EVICT end");
} catch (HibernateException e_) {
e_.printStackTrace();
NTEVENT_LOG.error("Error while getting List of Dictionary entries");
} finally {
if (session != null && session.isOpen()) {
try {
HibernateUtils.closeSessions();
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return dictonaries;
}
When I add the criteria, I get the following error:
org.hibernate.QueryException: could not resolve property: coding system of : com.artificialmed.domain.dictionary.model.DictionaryToken
I know that it has something to do with the nature of the object which is really a join between my dictionary class and the underlying table and my token class and table.
The field codingsystem is a field in my dictionary class. I think I am suppose to use aliases but I don't know how to do this under the current circumstances. Any help would be greatly appreciated.

This was a newbie problem. Hibernate requires the getters and setters of the models that reflect the tables to be of a specific format. The getter MUST BE get+ where name is the fieldname in the underlying table. The setter MUST BE set+ where name is the fieldname of the underlying table. And yes the first letter of Name must capitalized.

Composite Key - Hibernate - java

Missed #EmbeddedId annotation in Grocery.java. Update your code as below. #EmbeddedId private GroceryId id;

Just use #EmbeddedId.There must be only one EmbeddedId annotation and no Id annotation when the EmbeddedId annotation is used. #EmbeddedId private GroceryId id;
