This is another way to configure hibernate; here, we will create a file with the .properties extension. Usually called hibernate.properties, this file is a replacement for hibernate.cfg.xml. You can use any approach (either cfg.xml or the properties file). However, the properties file is better for startup, and it is the easiest approach to get started quickly.
This is a simpler representation of an XML file. Hibernate searches for the XML file or the properties file at startup to find the configuration in your classpath. We can use any one of these options. You can use both of them at the same time, but this is uncommon because hibernate gives priority to the XML file over properties; the properties file is simply ignored in such cases.
Now, we will create a file called hibernate.properties in our classpath and write the following properties in the file. The following code represents hibernate.cfg.xml in the hibernate.properties file:
… hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.connection.driver_class=com.mysql.jdbc.Driver hibernate.connection.url=jdbc:mysql://localhost:3306/kode12 hibernate.connection.username=root hibernate.connection.password=root show_sql=true hbm2ddl.auto=update …
When we create an instance of the Configuration class, it will look for hibernate.cfg.xml or hibernate.properties in our classpath. If we use a .properties file, it'll get all of the property defined in the file, rather than create a Configuration object.
