Location of hibernate.cfg.xml in project?

I created a project with following structure:

HibernateUtil:

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
            return new Configuration().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();
    }

}

at line

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");

I have error

Initial SessionFactory creation failed.org.hibernate.HibernateException: C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml not found Exception in thread "main" java.lang.ExceptionInInitializerError at logic.HibernateUtil.buildSessionFactory(HibernateUtil.java:19) at logic.HibernateUtil.(HibernateUtil.java:9) at logic.Main.main(Main.java:12) Caused by: org.hibernate.HibernateException: C:\Users\Nikolay_Tkachev\workspace\hiberTest\src\logic\hibernate.cfg.xml not found at org.hibernate.internal.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:173) at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:1947) at org.hibernate.cfg.Configuration.configure(Configuration.java:1928) at logic.HibernateUtil.buildSessionFactory(HibernateUtil.java:14) ... 2 more

What is the reason for the error and how do I fix it?

Give the path relative to your project.

Create a folder called resources in your src and put your config file there.

   configuration.configure("/resources/hibernate.cfg.xml");

And If you check your code

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return new Configuration().configure().buildSessionFactory();

In two lines you are creating two configuration objects.

That should work(haven't tested) if you write,

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return  configuration.buildSessionFactory();

But It fails after you deploy on the server,Since you are using system path than project relative path.

Somehow placing under "src" folder didn't work for me.

Instead placing cfg.xml as below:

[Project Folder]\src\main\resources\hibernate.cfg.xml

worked. Using this code

new Configuration().configure().buildSessionFactory().openSession();

in a file under

    [Project Folder]/src/main/java/com/abc/xyz/filename.java

In addition have this piece of code in hibernate.cfg.xml

<mapping resource="hibernate/Address.hbm.xml" />
<mapping resource="hibernate/Person.hbm.xml" />

Placed the above hbm.xml files under:

EDIT:

[Project Folder]/src/main/resources/hibernate/Address.hbm.xml
[Project Folder]/src/main/resources/hibernate/Person.hbm.xml

Above structure worked.

You can put the file "hibernate.cfg.xml" to the src folder (src\hibernate.cfg.xml) and then init the config as the code below:

Configuration configuration = new Configuration();          
sessionFactory =configuration.configure().buildSessionFactory();

This is an reality example when customize folder structure: Folder structure, and initialize class HibernateUtil

with:

return new Configuration().configure("/config/hibernate.cfg.xml").buildSessionFactory();

mapping:

with customize entities mapping files:

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <mapping class="com.vy.entities.Users"/>
        <mapping class="com.vy.entities.Post"/>
        <mapping resource="config/Users.hbm.xml"/>      
        <mapping resource="config/Post.hbm.xml"/>               
    </session-factory>
</hibernate-configuration>

(Note: Simplest way, if you follow default way, it means put all xml config files inside src folder, when build sessionFactory, only:

return new Configuration().configure().buildSessionFactory();

)
