I want to encrypt the password in configuration file using Jasypt. For this I use a library based in jasypt because seems that there are some problems with it using hibernate 4.3.
The password is stored in an environment variable named PSS_RES and is encripted with PBEWithMD5AndTripleDes algorithm
The configuration file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM

I have a spring boot project. I put in my resource folder hibernate.cfg.xml file.
this is my hibernate.cfg.xml file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

I have a hibernateUtil class used to instantiate a hibernate session.
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory()
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
// return new Configuration().configure().buildSessionFactory();
return new AnnotationConfiguration().configure().buildSessionFactory();
}
catch (Throwable ex)
{
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory()
{
return sessionFactory;
}
public static void shutdown()
{
// Close caches and connection pools
getSessionFactory().close();
}
}
In my application controller I have an endpoint in which I am requesting my mysql database.
#RequestMapping("/getbuildinginfo/{buildingid}")
public void getbuildinginfo(String buildingid)
Session session = null;
session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String query = "select * from exportbatch.exportbatch";
SQLQuery sqlQuery = session.createSQLQuery(query);
List<Object[]> rows = sqlQuery.list();
HibernateUtil.shutdown();
This works fine the first time I run the project, but if I call the endpoint a second time, I am getting this exception:
org.hibernate.service.UnknownServiceException: Unknown service requested [org.hibernate.engine.jdbc.connections.spi.ConnectionProvider]
Could someone help me with this ? why it works the first time? Is it a spring boot context problem? if yes how could I resolve it ?
What i do wrong? After running main class i have view in console like in current screenshot below and the console continues to work and nothing happens.

hibernateUtil.class:
package hibernateConn;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static SessionFactory sessionFactory = null;
static {
Configuration cfg =
new Configuration().configure("/hibernateConn/hibernate.cfg.xml");

}
}
Main.Class:
package hibernateConn;
import org.hibernate.SessionFactory;
public class Main {
public static void main(String[] args) {
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
}
}
After I run Main.class I have in console:
And that's all. Nothing more, the program continues to work and nothing happens, as if recursion occurs ... Maybe I did not correctly specify the settings in xml?
I rewrote the HibernateUtil.class :
static {
try{
sessionFactory = new Configuration().configure("/hibernateConn/hibernate.cfg.xml").buildSessionFactory();
}catch(Throwable ex){
System.err.println("++++Initial SessionFactory creation failed.++++: " + ex);
ex.printStackTrace();
}
}
public static SessionFactory getSessionFactory(){
return sessionFactory;
}
and it all worked. The question can be closed.
I am doing the introductory tutorial on Hibernate from PluralSight.
For my database, I am using MYSQL.
In my main method, I am creating an object and I am trying to save it.
However, I get the following error:
Exception in thread "main" org.hibernate.MappingException: Unknown entity: com.simpleprogrammer.User

My main method is:
public static void main(String[] args) {
System.out.println("Hello World!");
Session session = HibernateUtilities.getSessionFactory().openSession();
session.beginTransaction();
User user = new User();
user.setName("Joe");
user.setGoal(250);
session.save(user);
session.getTransaction().commit();
session.close();
HibernateUtilities.getSessionFactory().close();
}
The error appears on the line with session.save(user);
My Utilities class:
package com.simpleprogrammer;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public class HibernateUtilities {
private static SessionFactory sessionFactory;
private static StandardServiceRegistryBuilder ssrb;
static
{
try
{
Configuration configuration = new Configuration().configure("hibernate.cfg.xml");
ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory(ssrb.build());
}
catch(HibernateException exception)
{
System.out.println("Problem creating session factory");
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
My hibernate.cfg.xml:
<?xml version="1.0" encoding="UTF-8"?>

</session-factory
</hibernate-configuration>
I am sorry to post all this code, but I'm not sure which part is relevant.
I suspect that my error is caused by the database connection, but I'm not sure how to check that.
I had a syntactic error on the line:
</session-factory
This was in hibernate.cfg.xml
This is my first contribution to stackoverflow.com. And I was facing similar error,but now I resolved it by this given solution. So, I am writing this Answer.
You have to change your utility file like this:
static
{
try
{
Configuration configuration = new Configuration().configure("hibernate.cfg.xml");
//ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory();
}
catch(HibernateException exception)
{
System.out.println("Problem creating session factory");
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
ssrb variable declaration and definition must be removed.
put configuration.buildSessionFactory(); instead of configuration.buildSessionFactory(ssrb.build());
I am trying to connect to a Microsoft SQL 2008 server through hibernate.it's not getting connected, following is hibernate.cfg.xml
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.password">1234</property>
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;databaseName=TEST</property>
<property name="hibernate.connection.username">username</property>

<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.show_sql">true</property>
</session-factory>
</hibernate-configuration>
`
And here is the code I use to try and establish an connection and do a query :
package com.simpleprogrammer;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
public class HibernateUtilities {
private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;
static {
try {
Configuration config = new Configuration().configure().addResource("hibernate.cfg.xml");
serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
sessionFactory = config.buildSessionFactory(serviceRegistry);
}catch(HibernateException he){
System.out.println("Problem Caught ! " + he );
}
}
public static SessionFactory getSessionFactory(){
return sessionFactory;
}
}
`
The Main method :
package com.simpleprogrammer;
import org.hibernate.Session;
public class Program {
public static void main(String[] args) {
System.out.println("Hello World!") ;
Session session = HibernateUtilities.getSessionFactory().openSession();
session.close();
}
}
jar file was missing jboss-transaction-api_1.2_spec-1.0.0, Simply add it in project and it start working
I started using Hibernate today and tested a simple example but I'm getting the error: hibernate.cfg.xml not found.
I putted the hibernate.cfg.xml file in the src folder and here is its content:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

</hibernate-configuration>
And I putted the HibernateUtil.java file under util folder (src/util) and here is its content
package util;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory()
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static void shutdown() {
// Close caches and connection pools
getSessionFactory().close();
}
}
I also have the Jars added to the build path.
My class Test.java :
import ...
public class Test {
public static void main(String[] args) {
// TODO Auto-generated method stub
ProductDao pd = new ProductDao();
try {
Product p = new Product("PC", 1000L);
pd.add(p);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
The add method :
public void add(Product p) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.beginTransaction();
session.save(p);
tx.commit();
}
Thanks in advance
If using maven try putting it in
/src/main/resources
If using simple eclipse project (without maven), put it in project root directory (not in the src)
Also you misspelled the name of the file in the source
return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();
it must be
hibernate.cfg.xml
If its a Maven project just add cfg.xml file in /src/main/resources in eclips
