public class EmbeddedDatabaseFactoryBean extends EmbeddedDatabaseFactory implements FactoryBean<javax.sql.DataSource>, InitializingBean, DisposableBean
EmbeddedDatabaseFactory that implements FactoryBean
for registration as a Spring bean. Returns the actual DataSource that
provides connectivity to the embedded database to Spring.
The target DataSource is returned instead of an EmbeddedDatabase
proxy since the FactoryBean will manage the initialization and destruction
lifecycle of the embedded database instance.
Implements DisposableBean to shutdown the embedded database when the
managing Spring container is being closed.

Return an instance (possibly shared or independent) of the object

Return the type of object that this FactoryBean creates,
or
null if not known in advance. |
boolean |
isSingleton()
Is the object managed by this factory a singleton? That is,
will
FactoryBean.getObject() always return the same object
(a reference that can be cached)? |

setDatabaseCleaner(DatabasePopulator databaseCleaner)
Set a script execution to be run in the bean destruction callback,
cleaning up the database and leaving it in a known state for others.

InitializingBeanBeanFactory after it has set all bean properties
and satisfied BeanFactoryAware, ApplicationContextAware etc.
This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

FactoryBeanAs with a BeanFactory, this allows support for both the
Singleton and Prototype design pattern.
If this FactoryBean is not fully initialized yet at the time of
the call (for example because it is involved in a circular reference),
throw a corresponding FactoryBeanNotInitializedException.
As of Spring 2.0, FactoryBeans are allowed to return null
objects. The factory will consider this as normal value to be used; it
will not throw a FactoryBeanNotInitializedException in this case anymore.
FactoryBean implementations are encouraged to throw
FactoryBeanNotInitializedException themselves now, as appropriate.

This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
null here. Therefore it is highly recommended to implement
this method properly, using the current state of the FactoryBean.

FactoryBeanFactoryBean.getObject() always return the same object
(a reference that can be cached)?
NOTE: If a FactoryBean indicates to hold a singleton object,
the object returned from getObject() might get cached
by the owning BeanFactory. Hence, do not return true
unless the FactoryBean always exposes the same reference.
The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
NOTE: This method returning false does not
necessarily indicate that returned objects are independent instances.
An implementation of the extended SmartFactoryBean interface
may explicitly indicate independent instances through its
SmartFactoryBean.isPrototype() method. Plain FactoryBean
implementations which do not implement this extended interface are
simply assumed to always return independent instances if the
isSingleton() implementation returns false.
