PoolingConfig Config interface for a pooling target source.

ThreadLocalTargetSourceStats Statistics for a ThreadLocal TargetSource.

Class Summary

AbstractBeanFactoryBasedTargetSource Base class for TargetSource implementations that are based on a Spring BeanFactory, delegating to Spring-managed bean instances.

AbstractPoolingTargetSource Abstract superclass for pooling TargetSources that maintains a pool of target instances, acquiring and releasing a target object from the pool for each method invocation.

AbstractPrototypeBasedTargetSource Base class for dynamic TargetSources that can create new prototype bean instances to support a pooling or new-instance-per-invocation strategy.

CommonsPoolTargetSource Jakarta Commons pooling implementation extending AbstractPoolingTargetSource.

EmptyTargetSource Canonical TargetSource when there's no target, and behavior is supplied by interfaces and advisors.

HotSwappableTargetSource Implementation of TargetSource interface 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 from a BeanFactory.

PrototypeTargetSource TargetSource that creates a new instance of the target bean for each request.

SingletonTargetSource Implementation of the TargetSource interface that holds a local object.

ThreadLocalTargetSource Alternative to an object pool.

Package org.springframework.aop.target Description

Core Spring AOP interfaces, built on AOP Alliance AOP interoperability interfaces.
Any AOP Alliance MethodInterceptor is usable in Spring.
Spring AOP also offers:

Introduction support
A Pointcut abstraction, supporting "static" pointcuts (class and method-based) and "dynamic" pointcuts (also considering method arguments). There are currently no AOP Alliance interfaces for pointcuts.
A full range of advice types, including around, before, after returning and throws advice.
Extensibility allowing arbitrary custom advice types to be plugged in without modifying the core framework.

Spring AOP can be used programmatically or (preferably) integrated with the Spring IoC container.
