Hibernate list using cache? -Not updating entity attribute - mysql

Question

I have an application that uses hibernate.
I did the following:
Used List to list some entities on database
Logged in my Mysql Database manualy and updated a field in some
entities
Used List again in hibernate doing an identical query as 1
The entity that hibernate listed was not updated.
If I close and open the application. it then shows the entity updated correctly.
Is hibernate using some kind of cache by default?
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/XXX</property>
<property name="hibernate.connection.username">XXXXXXXXXX</property>
<property name="hibernate.connection.password">XXXXXXXXXX</property>
<property name="show_sql">true</property>
Code that lists the entity:
Session s = HibernateUtil.getSession();
Criteria c = s.createCriteria(Solicitacao.class, "s");
//Add some Restrictions here
List<Solicitacao> ls = c.list();
s.close();
My Session factory:
public class HibernateUtil {
private static SessionFactory sessionFactory = null;
static {
// Configurações iniciais de caminho dos diretórios e arquivos
URL url = HibernateUtil.class.getProtectionDomain().getCodeSource().getLocation();
File myFile = null;
try {
myFile = new File(url.toURI());
} catch (Exception ex) {
}
File dir = myFile.getParentFile();
File xml = new File(dir, "hibernate.cfg.xml");
/*
* sessionFactory = new AnnotationConfiguration() .configure("br/com/netradiobrasil/pcp/" +
* "hibernate/hibernate.cfg.xml") .buildSessionFactory();
*/
sessionFactory = new AnnotationConfiguration().configure(xml).buildSessionFactory();
}
public static Session getSession() {
return sessionFactory.openSession();
}
}
I tryed to add those lines in my hibernate.cfg.xml
<property name="hibernate.cache.use_query_cache">false</property>
<property name="hibernate.cache.use_second_level_cache">false</property>
<property name="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
Also tryed to use: session.setCacheMode(CacheMode.IGNORE)
but still didnt solve my problem

Answer 1

Let me guess
After executing this
Session s = HibernateUtil.getSession();
Criteria c = s.createCriteria(Solicitacao.class, "s");
//Add some Restrictions here
List<Solicitacao> ls = c.list();
You changed entries in database manually and then reran the query ? If yes then can you close the session and then rerun your code ?

Adding those lines in my hibernate.cfg.xml - that enables c3p0 fixed my problem
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">40</property>
<property name="hibernate.c3p0.timeout">300</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.idle_test_period">100</property>
