hibernate jpa application suspends everytime I want to run it - java

I'm using Hibernate 5.2 with JPA 2.1 Library.Every time I want to run my application it doesn't stop - I have to stop it manually because it's still working. Records are being saved to the database correctly. These are my project files:
Main.java
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("testjpa");
EntityManager em = entityManagerFactory.createEntityManager();
em.getTransaction().begin();
Kraj country = new Kraj();
country.setNazwa("ExampleCountry");
em.persist(country);
em.getTransaction().commit();
em.close();
}

I got this error when running Spring Boot 2.0.5 with JDK11. To fix it, I had to update the javassist library version (Gradle is my build tool):
compile('org.javassist:javassist:3.23.1-GA') {force = true}
For more info on migrating to JDK11, I found this blog post useful. Alternatively, upgrading to Spring Boot to 2.1 will fix this issue.
Do you run Spring Boot on the JDK 11?
I met the same question when I switched to JDK 11.
I resolved it by changing the Spring Boot version.
Thanks for # cpierceworld, I declare my student as
package edu.aspire.li;
import java.io.Serializable;
public class Student implements Serializable{
private int sno;
private String name;
private String email;
private long mobile;
public Student(){
System.out.println("This is to construct student");
}
public int getSno() {
return sno;
}
public void setSno(int sno) {
this.sno = sno;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public long getMobile() {
return mobile;
}
public void setMobile(long mobile) {
this.mobile = mobile;
}
}
There is a name conflict with student.hbm.xml
<property name ="sname" column="SNAME" type="string" length="100"/>

Check user exists in database using hibernate

I am new in hibernate
I have a UserDAO class and a method to determine whether user exists in a specific table or not.
This is my users table in hb3 database:
And this is my class:
public static void main(String[] args) {
System.out.println(userExistsinDB("ABC"));
}
public static boolean userExistsinDB(String username) {
String queryStr = "Select * from users where username=" + username; // since username is unique
SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
Query query = session.createSQLQuery(queryStr);
System.out.println(query.getFirstResult());
session.getTransaction().commit();
session.close();
sessionFactory.close();
return false;
}
But the result is null in query.getFirstResult() , Why?
I have ABC username in users table.

Try this:
org.hibernate.Query query = session.createQuery("from users where username = :username");
query.setParameter("username", username);
query.uniqueResult();
You should use parameterized query. It returns null because string literals should be enclosed by quote notation.

Hibernate: Connection to DB2 database fails (dialect?)

I am desperate trying to connect to a DB2 database via hibernate. Problem is here, I know, where the error comes from but I can't solve it or rather don't understand it. Maybe you can help me fix this problem. I would be very grateful!
The following code shows my hibernate.cfg.xml:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.DB2Dialect</property>
<property name="hibernate.connection.driver_class">com.ibm.db2.jcc.DB2Driver</property>
<property name="hibernate.connection.url">jdbc:db2://db2.example.com:50001/databasename</property>
<property name="hibernate.connection.username">mydbuser</property>
<property name="hibernate.connection.password">mydbpass</property>
<property name="hibernate.connection.pool_size">10</property>
<property name="show_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping class="media.definitions.Product" />
</session-factory>
</hibernate-configuration>
This following code is a class which I've built by a tutorial:
package media.frontend;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
Configuration cfg = new Configuration().configure("hibernate.cfg.xml");
StandardServiceRegistryBuilder sb = new StandardServiceRegistryBuilder();
sb.applySettings(cfg.getProperties());
StandardServiceRegistry standardServiceRegistry = sb.build();
sessionFactory = cfg.buildSessionFactory(standardServiceRegistry);
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
And the following error comes immediately when I start the program (which only tries to catch information of a single column). I've pasted the whole output:

I was facing similar issue in my code. Then i tried updating the recent versions of DB2 jars into my server and the code started working. Try to update your DB2 jar.

Hibernate: Disable logging to console WITHOUT log4j

I have hibernate and I would like to decrease the logging that happens in console everytime it runs. I do not have log4j in my application nor do I want to add it in.
Here is an example of the logs I get everytime I run my app

As per your log details I understood that hibernate version is- Hibernate 4.0.4.Final.Since version 4.0, Hibernate has used the JBoss logging library and so even your application does not contain any log4j still hibernate is using JBoss logging provider as default provider.
For more please go through this link:
http://docs.jboss.org/hibernate/orm/4.3/topical/html/logging/Logging.html
Hope this info will help you to understand why logs are still available without any log4j.
You can try to disable all Logger functions using java.util.logging :
private void disableLogging() {
LogManager logManager = LogManager.getLogManager();
Logger logger = logManager.getLogger("");
logger.setLevel(Level.SEVERE); //could be Level.OFF
}
It would affect any other Logger you're using, but in some cases may be useful.
