public interface TargetSource extends TargetClassAware
TargetSourceis used to obtain the current "target" of an AOP invocation, which will be invoked via reflection if no around advice chooses to end the interceptor chain itself.
TargetSource is "static", it will always return
the same target, allowing optimizations in the AOP framework. Dynamic
target sources can support pooling, hot swapping, etc.
Application developers don't usually need to work with
TargetSources directly: this is an AOP framework interface.
