For full Hibernate configuration support, you can point the ORM extension to an XML file containing any configuration properties you wish to configure:
Copy this.ormSettings = {
// ...
ormconfig : "./config/persistence.xml"
};
Copy <!-- persistence.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"https://hibernate.org/dtd/hibernate-reverse-engineering-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- https://docs.jboss.org/hibernate/orm/5.4/javadocs/org/hibernate/cfg/AvailableSettings.html#USE_SQL_COMMENTS -->
<property name="hibernate.use_sql_comments">true</property>
<property name="hibernate.cache.use_query_cache">true</property>
