Inserting many rows with hibernate is very slow

Inserting many rows with hibernate is very slow - java

I have about 5000 rows to insert to my database using hibernate, but it lasts about 2 minutes, I have no idea why. Here is my code:
hibernate.cfg.xml:

If your design allows you could give plain SQL a change (or maybe there is also a HQL equivalent).
I guess the INSERT ... ON DUPLICATE KEY UPDATE Syntax should be way faster when upserting multiple data with VALUES:

Delete a Simple row from database

I have 2 tables, testInput and testCases and in testInput i have a FK with the id of the other table.
So basically the rows I want to delete are id of the input, id of the testCase, name and a description.
'43', '21', 'USERNAME', 'USERNAME'
'44', '21', 'PASSWORD', 'PASSWORD'
I tried to delete that row and I get
java.sql.SQLIntegrityConstraintViolationException: Cannot delete or
update a parent row: a foreign key constraint fails
(mydb.testInput, CONSTRAINT fk02 FOREIGN KEY (testCase)
REFERENCES testCases (idtestCase) ON DELETE NO ACTION ON UPDATE NO
ACTION)
I don't want to delete the record of testCase. I just want to delete the inputs of that testCase. What do I do?
code if u want...
List<TestInput> previousInputs = TestInput.getInputs(testCaseName);
for(TestInput in : previousInputs) {
Database.deleteObject(in);
}
//delete the object to the database
public static void deleteObject(Object object) {
SessionFactory factory = HibernateUtil.getSessionFactory();
Session session = factory.openSession();
Transaction tx = null;
try{
tx = session.beginTransaction();
session.delete(object);
tx.commit();
}catch (HibernateException e) {
if (tx!=null) tx.rollback();
e.printStackTrace();
}finally {
session.close();
}
}
xml TestCases
<hibernate-mapping>
<class name="TestCase" table="testCases">

Change the constraint on the foreign key fk02 from ´NO ACTION´ to 'SET NULL'
FOREIGN KEY (idtestcase)
REFERENCES testCases(idtestCase)
ON DELETE SET NULL

Attribute "column" must be declared for element type "one-to-many"

i would like to create a dynamique web project with hibernate 3.In this project i have 2 classes and relation with them. The first class is Ecole and this is the attributs
package essai1;
import java.util.HashSet;
import java.util.Set;
public class Ecole {
private int id_ecole;
private String nom_ecole;
private Set<Etudiant> etudiants = new HashSet<>();
public Set<Etudiant> getEtudiants() {
return etudiants;
}
public void setEtudiants(Set<Etudiant> etudiants) {
this.etudiants = etudiants;
}
public int getId_ecole() {
return id_ecole;
}
public void setId_ecole(int id_ecole) {
this.id_ecole = id_ecole;
}
public String getNom_ecole() {
return nom_ecole;
}
public void setNom_ecole(String nom_ecole) {
this.nom_ecole = nom_ecole;
}
public Ecole() {
super();
}}
the second class has this attributs
package essai1;
public class Etudiant {
private int id_etudiant;
private String nom_etudiant;
private String prenom_etudiant;
private Ecole ecole;
public int getId_etudiant() {
return id_etudiant;
}
public void setId_etudiant(int id_etudiant) {
this.id_etudiant = id_etudiant;
}
public String getNom_etudiant() {
return nom_etudiant;
}
public void setNom_etudiant(String nom_etudiant) {
this.nom_etudiant = nom_etudiant;
}
public String getPrenom_etudiant() {
return prenom_etudiant;
}
public void setPrenom_etudiant(String prenom_etudiant) {
this.prenom_etudiant = prenom_etudiant;
}
public Ecole getEcole() {
return ecole;
}
public void setEcole(Ecole ecole) {
this.ecole = ecole;
}
public Etudiant() {
super();
}}
I have the folder of the mapping Ecole.hbm.xml through which i create this file
<?xml version="1.0" encoding='UTF-8' ?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</property>
<set name="etudiants" inverse="true" table="ETUDIANT" cascade="all">

<column name="id_ecole" not-null="true"></column>
</key>
<one-to-many class="essai1.Etudiant" column="idEtudiant" />
</set>
<!-- <bag name="etudiants" table="Etudiant" lazy="true" inverse="true"

<column name="idEtudint" ></column> </one-to-many> </bag> -->
</class>
</hibernate-mapping>
In this file i have the problem of the mapping between the class of Ecole and the class Etudiant in the ligne one-to-many that i can't to add the attribute column="idEtudiant" in this tag
the file of hibernate.cfg.xml is here
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

</session-factory>
</hibernate-configuration>
the file of mapping of Etudiant.hbm.xml is clearly and it has no problem and this is the code
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</hibernate-mapping>
the file of the hibernateUtil.java is there also
package util;

throw new ExceptionInInitializerError(ex);
}
}
// public static final ThreadLocal session = new ThreadLocal();
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
the jars were download :
antlr-2.7.6.jar

dom4j-1.6.1.jar
ehcache-1.2.3.jar
hibernate3.jar
log4j.jar
mysql-connector-java-5.0.4-bin.jar
the database
create database essaihibernate; use essaihibernate; CREATE TABLE `essaihibernate`.`ECOLE` ( `id_ecole` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, `nom_ecole` TEXT NOT NULL, PRIMARY KEY (`id_ecole`) );
and the second table Etudiant is there
CREATE TABLE `essaihibernate`.`ETUDIANT` ( `id_etudiant` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, `nom_etudiant` TEXT NOT NULL, `prenom_etudiant` TEXT NOT NULL, `id_ecole` INTEGER UNSIGNED NOT NULL, PRIMARY KEY (`id_etudiant`), CONSTRAINT `FK_ETUDIANT_1` FOREIGN KEY `FK_ETUDIANT_1` (`id_ecole`) REFERENCES `ecole` (`id_ecole`) ON DELETE RESTRICT ON UPDATE RESTRICT );
the document imposes this orders of this all instructions but i can to mapped in my database because i have a problem with the column in the file Ecole.hbm.xml at the ligne 17
<one-to-many class="essai1.Etudiant" column="idEtudiant" />
the erreur is Attribute "column" must be declared for element type "one-to-many"
What can I do? I am very disappointed. help me my friend I am waiting for you

This, from the Etudiant class
private int id_etudiant;
private String nom_etudiant;
private String prenom_etudiant;
is not what you have defined in the corresponding xml file, Etudiant.hbm.xml

No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode \-[IDENT] IdentNode: 'locationCode' {originalText=locationCode}

I am trying to create a simple project using Hibernate
I have the following classes :
Model :
public class InputHStock implements Serializable {
private long hsID;
private String locationCode ;
private String itemCode;
private int stock;
DAO :
public class InputHStockDAO {
public List<InputHStock> getAllIHS() {
List<InputHStock> ihs = new ArrayList<InputHStock>();
Transaction trns = null;
Session session = HibernateUtil.getSessionFactory().openSession();
try {
trns = session.beginTransaction();
ihs = session.createQuery("select locationCode ").list();
} catch (RuntimeException e) {
e.printStackTrace();
} finally {
session.flush();
session.close();
}
return ihs;
}
}
hibernate.cfg.xml :
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<property name="hibernate.current_session_context_class">thread</property>
<mapping resource="InputHStock.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Mapping :
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC

However When I run the project I have the following error :
No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode
-[IDENT] IdentNode: 'locationCode' {originalText=locationCode}
Any ideas ?

org.hibernate.NonUniqueResultException: query did not return a unique result: 462

I'm working on an application with Spring using SpringMVC,, i'm encountering the following error and i don't know how to deal with it .

this is what i want to do (UML): imgur
this is the link of my last error for more infos : Link
can some one help ?

Your question is a real mess... but if you read the exception:
Provided id of the wrong type. Expected: class java.lang.Integer, got class java.lang.String
Anf after you take a look to your Departement class, it has only 2 fields and one set (according to the hibernate mapping):
int id;
String nomDepartament;
Set employees;
That only can mean, youre passing the nomDepartament field instead of id somewhere in your code...
But as far as you are not providing, the Departement class or DepartementImplMetier.create() method, that is the one causing the exception I cannot say more...
So... start here focus your problems, and provide only important parts of the code.

Getting org.hibernate.MappingException

This is my first question in Stackoverflow. I'd hope be clear. I'm getting troubles with Hibernate mapping and I don't know where the error is. When I tried to run a HQL like
from Sensor
I get the following exception
org.hibernate.MappingException: Association references unmapped class: sipiaHibernate.TipoSensor

I'm working on netbeans 7 with openjdk6, hibernet 3.2.5 and MySQL database. I have all the POJO's class in the package sipiaHibernate. All the tables mentioned in the configuration files are in my database. I generated the POJO classes & the mapping files using the netbeans hibernet utility.

Exists your TipoSensor class? The mapping hibernate not found your class

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Inserting many rows with hibernate is very slow - java

If your design allows you could give plain SQL a change (or maybe there is also a HQL equivalent). I guess the INSERT ... ON DUPLICATE KEY UPDATE Syntax should be way faster when upserting multiple data with VALUES: http://dev.mysql.com/doc/refman/5.6/en/insert-on-duplicate.html
