Interface Summary

Interface	Description
PoolingConfig	Config interface for a pooling target source.
ThreadLocalTargetSourceStats	Statistics for a ThreadLocal TargetSource.

Class Summary

Class	Description
AbstractBeanFactoryBasedTargetSource	Base class for TargetSource implementations that are based on a Spring BeanFactory, delegating to Spring-managed bean instances.
AbstractLazyCreationTargetSource	TargetSource implementation that will lazily create a user-managed object.
AbstractPoolingTargetSource	Abstract base class for pooling TargetSource implementations which maintain a pool of target instances, acquiring and releasing a target object from the pool for each method invocation.
AbstractPrototypeBasedTargetSource	Base class for dynamic TargetSource implementations that create new prototype bean instances to support a pooling or new-instance-per-invocation strategy.
CommonsPool2TargetSource	TargetSource implementation that holds objects in a configurable Apache Commons2 Pool.
CommonsPoolTargetSource	Deprecated as of Spring 4.2, in favor of CommonsPool2TargetSource
EmptyTargetSource	Canonical TargetSource when there is no target (or just the target class known), and behavior is supplied by interfaces and advisors only.
HotSwappableTargetSource	TargetSource implementation that caches a local target object, but allows the target to be swapped while the application is running.
LazyInitTargetSource	TargetSource that lazily accesses a singleton bean from a BeanFactory.
PrototypeTargetSource	TargetSource implementation that creates a new instance of the target bean for each request, destroying each instance on release (after each request).
SimpleBeanTargetSource	Simple TargetSource implementation, freshly obtaining the specified target bean from its containing Spring BeanFactory.
SingletonTargetSource	Implementation of the TargetSource interface that holds a given object.
ThreadLocalTargetSource	Alternative to an object pool.

Package org.springframework.aop.target Description

This package contains implementations of the org.springframework.aop.TargetSource interface.
The simplest implementation is the SingletonTargetSource, used by default in the AOP framework to wrap a single target instance. This is normally appropriate.
Other provided implementations include pooling implementations, that provide a target from a pool for each request, ensuring a single threaded programming model; and a "prototype" implementation, that uses a new target instance for each invocation.
