public class ThreadLocalTargetSource
Alternative to an object pool. This TargetSource uses a threading model in which every thread has its own copy of the target. There's no contention for targets. Target object creation is kept to a minimum on the running server.
Application code is written as to a normal pool; callers can't assume they will be dealing with the same instance in invocations in different threads. However, state can be relied on during the operations of a single thread: for example, if one caller makes repeated calls on the AOP proxy.
Cleanup of thread-bound objects is performed on BeanFactory destruction,
calling their DisposableBean.destroy()
method if available.
Be aware that many thread-bound objects can be around until the application
actually shuts down.
