Known Direct Subclasses |
Known Indirect Subclasses |
Base class for Spring-based EJB 2.x beans. Not intended for direct subclassing:
Extend AbstractStatelessSessionBean
, AbstractStatefulSessionBean
or AbstractMessageDrivenBean
instead.
Provides a standard way of loading a Spring BeanFactory. Subclasses act as a
facade, with the business logic deferred to beans in the BeanFactory. Default
is to use a ContextJndiBeanFactoryLocator
,
which will initialize an XML ApplicationContext from the class path (based on a JNDI
name specified). For a different locator strategy, setBeanFactoryLocator
may be called (before your EJB's ejbCreate
method is invoked,
e.g. in setSessionContext
). For use of a shared ApplicationContext between
multiple EJBs, where the container class loader setup supports this visibility, you may
instead use a ContextSingletonBeanFactoryLocator
.
Alternatively, setBeanFactoryLocator(BeanFactoryLocator)
may be called with a custom implementation
of the BeanFactoryLocator
interface.
Note that we cannot use final
for our implementation of EJB lifecycle
methods, as this would violate the EJB specification.

EJB lifecycle method, implemented to invoke onEjbRemove()
and unload the BeanFactory afterwards.
Don't override it (although it can't be made final): code your shutdown
in onEjbRemove()
.
Set the BeanFactoryLocator to use for this EJB. Default is a ContextJndiBeanFactoryLocator.
Can be invoked before loadBeanFactory, for example in constructor or setSessionContext if you want to override the default locator.
Note that the BeanFactory is automatically loaded by the ejbCreate
implementations of AbstractStatelessSessionBean and
AbstractMessageDriverBean but needs to be explicitly loaded in custom
AbstractStatefulSessionBean ejbCreate
methods.
Set the bean factory locator key.
In case of the default BeanFactoryLocator implementation, ContextJndiBeanFactoryLocator, this is the JNDI path. The default value of this property is "java:comp/env/ejb/BeanFactoryPath".
Can be invoked before #loadBeanFactory, for example in the constructor
or setSessionContext
if you want to override the default locator key.
Subclasses must implement this method to do any initialization they would
otherwise have done in an ejbRemove()
method.
The BeanFactory will be unloaded afterwards.
This implementation is empty, to be overridden in subclasses.
The same restrictions apply to the work of this method as to an
ejbRemove()
method.
