[Hibernate] Access to Dialectresolutioninfo cannot is null when & #39;hibernate.dialect& #39; Not set

Use the following code on the hibernate official document to make this exception in the test times.

Org.hibernate.HibernateException:Access to Dialectresolutioninfo cannot is null when ' Hibernate.dialect ' not set

Package Org.hibernate.tutorial.util;import Org.hibernate.sessionfactory;import Org.hibernate.boot.registry.standardserviceregistrybuilder;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< C4/>new Configuration (). Configure (). Buildsessionfactory (    new Standardserviceregistrybuilder (). build ());        }        catch (Throwable ex) {            //Make sure your log the exception, as it might be swallowed            System.err.println ("Initial Se Ssionfactory creation failed. "+ ex);            throw new Exceptionininitializererror (ex);        }    }    public static Sessionfactory Getsessionfactory () {        return sessionfactory;    }}

Later changes to the old version number such as the following code exception disappears:

Configuration cfg = new configuration (); Sessionfactory SF = Cfg.configure (). Buildsessionfactory (); Session session = Sf.opensession ();

However, the Buildsessionfactory method is deprecated in the new version number, and finally the solution is found:

Configuration cfg = new configuration (). Configure (); sessionfactory = Cfg.buildsessionfactory (new Standardserviceregistrybuilder (). Applysettings (Cfg.getproperties ()). build ());

There is no further abnormality in the test.
