| Interface | Description |
|---|---|
| Aware |
Marker superinterface indicating that a bean is eligible to be
notified by the Spring container of a particular framework object
through a callback-style method.
|
| BeanClassLoaderAware |
Callback that allows a bean to be aware of the bean
class loader; that is, the class loader used by the
present bean factory to load bean classes. |
| BeanFactory |
The root interface for accessing a Spring bean container.
|
| BeanFactoryAware |
Interface to be implemented by beans that wish to be aware of their
owning
BeanFactory. |
| BeanNameAware |
Interface to be implemented by beans that want to be aware of their
bean name in a bean factory.
|
| DisposableBean |
Interface to be implemented by beans that want to release resources
on destruction.
|
| FactoryBean<T> |
Interface to be implemented by objects used within a
BeanFactory which
are themselves factories for individual objects. |
| HierarchicalBeanFactory |
Sub-interface implemented by bean factories that can be part
of a hierarchy.
|
| InitializingBean |
Interface to be implemented by beans that need to react once all their
properties have been set by a BeanFactory: for example, to perform custom
initialization, or merely to check that all mandatory properties have been set.
|
| ListableBeanFactory |
Extension of the
BeanFactory interface to be implemented by bean factories
that can enumerate all their bean instances, rather than attempting bean lookup
by name one by one as requested by clients. |
| NamedBean |
Counterpart of
BeanNameAware. |
| ObjectFactory<T> |
Defines a factory which can return an Object instance
(possibly shared or independent) when invoked.
|
| ObjectProvider<T> |
A variant of
ObjectFactory designed specifically for injection points,
allowing for programmatic optionality and lenient not-unique handling. |
| SmartFactoryBean<T> |
Extension of the
FactoryBean interface. |
| SmartInitializingSingleton |
Callback interface triggered at the end of the singleton pre-instantiation phase
during
BeanFactory bootstrap. |
| Class | Description |
|---|---|
| BeanFactoryUtils |
Convenience methods operating on bean factories, in particular
on the
ListableBeanFactory interface. |
| InjectionPoint |
A simple descriptor for an injection point, pointing to a method/constructor
parameter or a field.
|
| Exception | Description |
|---|---|
| BeanCreationException |
Exception thrown when a BeanFactory encounters an error when
attempting to create a bean from a bean definition.
|
| BeanCreationNotAllowedException |
Exception thrown in case of a bean being requested despite
bean creation currently not being allowed (for example, during
the shutdown phase of a bean factory).
|
| BeanCurrentlyInCreationException |
Exception thrown in case of a reference to a bean that's currently in creation.
|
| BeanDefinitionStoreException |
Exception thrown when a BeanFactory encounters an invalid bean definition:
e.g.
|
| BeanExpressionException |
Exception that indicates an expression evaluation attempt having failed.
|
| BeanInitializationException |
Exception that a bean implementation is suggested to throw if its own
factory-aware initialization code fails.
|
| BeanIsAbstractException |
Exception thrown when a bean instance has been requested for
a bean definition which has been marked as abstract.
|
| BeanIsNotAFactoryException |
Exception thrown when a bean is not a factory, but a user tries to get
at the factory for the given bean name.
|
| BeanNotOfRequiredTypeException |
Thrown when a bean doesn't match the expected type.
|
| CannotLoadBeanClassException |
Exception thrown when the BeanFactory cannot load the specified class
of a given bean.
|
| FactoryBeanNotInitializedException |
Exception to be thrown from a FactoryBean's
getObject() method
if the bean is not fully initialized yet, for example because it is involved
in a circular reference. |
| NoSuchBeanDefinitionException |
Exception thrown when a
BeanFactory is asked for a bean instance for which it
cannot find a definition. |
| NoUniqueBeanDefinitionException |
Exception thrown when a
BeanFactory is asked for a bean instance for which
multiple matching candidates have been found when only one matching bean was expected. |
| UnsatisfiedDependencyException |
Exception thrown when a bean depends on other beans or simple properties
that were not specified in the bean factory definition, although
dependency checking was enabled.
