Package org.hibernate.boot.registry

Defines service registry contracts application are likely to want to utilize for configuring Hibernate behavior.

Service registries are designed to be hierarchical. This works in 2 fashions. First registries can "hide" or "override" services from parent registries. It also allows granular building of registries as services become available.

BootstrapServiceRegistry is the base service registry, intended to be built via BootstrapServiceRegistryBuilder if you need customization. For non-customized BootstrapServiceRegistry usage, the BootstrapServiceRegistryBuilder and BootstrapServiceRegistry can be bypassed altogether.

Usually the next level in a standard registry set up is the StandardServiceRegistry, intended to be built by the StandardServiceRegistryBuilder if you need customization. The builder optionally takes the BootstrapServiceRegistry to use as a base; if none is provided a default one is generated assuming sensible defaults in Java SE and EE environments, particularly in respect to Class loading.
