getConfigurationProperties

public static Properties getConfigurationProperties(ParsedArguments args)

Boot-up the app by gathering properties needed for Hibernate start-up.
Method searches for values and then create the hibernate setup based on it.

Parameters:

args - values to be used as the most important for the setup

Returns:

properties for hibernate being able to connect to db

getConfigurationProperties

public static Properties getConfigurationProperties()

Loading hibernate setup data only from environmental and system properties. See the #getConfigurationProperties(ArgumentParser)

Returns:

properties setup with default configuration based on the values of system properties

getStandardRegistry

public static org.hibernate.boot.registry.StandardServiceRegistry getStandardRegistry(Properties setupProperties)

Generate hibernate registry while filling it with properties.

Parameters:

setupProperties - properties for connection

Returns:

hibernate standard registry

getHibernateStartupMetadata

public static org.hibernate.boot.Metadata getHibernateStartupMetadata(Properties setupProperties,
                                                                      org.hibernate.service.ServiceRegistry standardRegistry)

Setting up the Hibernate as standalone app. It uses the Metadata filled from provided properties.

Parameters:

setupProperties - properties, probably taken from getConfigurationProperties()
