package org.springframework.beans.factory
The core package implementing Spring's lightweight Inversion of Control (IoC) container.
Provides an alternative to the Singleton and Prototype design patterns, including a consistent approach to configuration management. Builds on the org.springframework.beans package.
This package and related packages are discussed in Chapter 11 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).

ClassDescriptionA 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.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.Exception thrown when a BeanFactory encounters an error when attempting to create a bean from a bean definition.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).Exception thrown in case of a reference to a bean that's currently in creation.Exception thrown when a BeanFactory encounters an invalid bean definition: e.g.Exception that indicates an expression evaluation attempt having failed.The root interface for accessing a Spring bean container.Interface to be implemented by beans that wish to be aware of their owningBeanFactory
.BeanFactoryInitializer<F extends ListableBeanFactory>Callback interface for initializing a SpringListableBeanFactory
prior to entering the singleton pre-instantiation phase.Convenience methods operating on bean factories, in particular on theListableBeanFactory
interface.Exception that a bean implementation is suggested to throw if its own factory-aware initialization code fails.Exception thrown when a bean instance has been requested for a bean definition which has been marked as abstract.Exception thrown when a bean is not a factory, but a user tries to get at the factory for the given bean name.Interface to be implemented by beans that want to be aware of their bean name in a bean factory.Thrown when a bean doesn't match the expected type.Exception thrown when the BeanFactory cannot load the specified class of a given bean.Interface to be implemented by beans that want to release resources on destruction.FactoryBean<T>Interface to be implemented by objects used within aBeanFactory
which are themselves factories for individual objects.Exception to be thrown from a FactoryBean'sgetObject()
method if the bean is not fully initialized yet, for example because it is involved in a circular reference.Sub-interface implemented by bean factories that can be part of a hierarchy.Interface to be implemented by beans that need to react once all their properties have been set by aBeanFactory
: e.g.A simple descriptor for an injection point, pointing to a method/constructor parameter or a field.Extension of theBeanFactory
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.Counterpart ofBeanNameAware
.Exception thrown when aBeanFactory
is asked for a bean instance for which it cannot find a definition.Exception thrown when aBeanFactory
is asked for a bean instance for which multiple matching candidates have been found when only one matching bean was expected.Defines a factory which can return an Object instance (possibly shared or independent) when invoked.A variant ofObjectFactory
designed specifically for injection points, allowing for programmatic optionality and lenient not-unique handling.Extension of theFactoryBean
interface.Callback interface triggered at the end of the singleton pre-instantiation phase duringBeanFactory
bootstrap.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.
