Imports

org.springframework.lang.NonNullApi, .NonNullFields

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).

Interface Summary

Modifier and Type	Interface and Description
public interface	Aware A 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.
public interface	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.
public interface	BeanFactory The root interface for accessing a Spring bean container.
public interface	BeanFactoryAware Interface to be implemented by beans that wish to be aware of their owning `BeanFactory`.
public interface	BeanNameAware Interface to be implemented by beans that want to be aware of their bean name in a bean factory.
public interface	DisposableBean Interface to be implemented by beans that want to release resources on destruction.
public interface	FactoryBean< the bean type T> Interface to be implemented by objects used within a `BeanFactory` which are themselves factories for individual objects.
public interface	HierarchicalBeanFactory Sub-interface implemented by bean factories that can be part of a hierarchy.
public interface	InitializingBean Interface to be implemented by beans that need to react once all their properties have been set by a `BeanFactory`: e.g. to perform custom initialization, or merely to check that all mandatory properties have been set.
public interface	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.
public interface	NamedBean Counterpart of `BeanNameAware`.
public interface	ObjectFactory< the object type T> Defines a factory which can return an Object instance (possibly shared or independent) when invoked.
public interface	ObjectProvider< the object type T> A variant of `ObjectFactory` designed specifically for injection points, allowing for programmatic optionality and lenient not-unique handling.
public interface	SmartFactoryBean< the bean type T> Extension of the `FactoryBean` interface.
public interface	SmartInitializingSingleton Callback interface triggered at the end of the singleton pre-instantiation phase during `BeanFactory` bootstrap.

Class Summary

Modifier and Type	Class and Description
public class	BeanCreationException Exception thrown when a BeanFactory encounters an error when attempting to create a bean from a bean definition.
public class	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).
public class	BeanCurrentlyInCreationException Exception thrown in case of a reference to a bean that's currently in creation.
public class	BeanDefinitionStoreException Exception thrown when a BeanFactory encounters an invalid bean definition: e.g. in case of incomplete or contradictory bean metadata.
public class	BeanExpressionException Exception that indicates an expression evaluation attempt having failed.
public abstract class	BeanFactoryUtils Convenience methods operating on bean factories, in particular on the `ListableBeanFactory` interface.
public class	BeanInitializationException Exception that a bean implementation is suggested to throw if its own factory-aware initialization code fails.
public class	BeanIsAbstractException Exception thrown when a bean instance has been requested for a bean definition which has been marked as abstract.
public class	BeanIsNotAFactoryException Exception thrown when a bean is not a factory, but a user tries to get at the factory for the given bean name.
public class	BeanNotOfRequiredTypeException Thrown when a bean doesn't match the expected type.
public class	CannotLoadBeanClassException Exception thrown when the BeanFactory cannot load the specified class of a given bean.
public class	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.
public class	InjectionPoint A simple descriptor for an injection point, pointing to a method/constructor parameter or a field.
public class	NoSuchBeanDefinitionException Exception thrown when a `BeanFactory` is asked for a bean instance for which it cannot find a definition.
public class	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.
public class	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.
