Alternative to an object pool. ThisTargetSourceuses 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.- 作者:

方法详细资料
getTarget
public Object getTarget() throws BeansException
Implementation of abstract getTarget() method. We look for a target held in a ThreadLocal. If we don't find one, we create one and bind it to the thread. No synchronization is required.- 指定者:
getTarget在接口中TargetSource- 返回:
- the target object which contains the joinpoint, or
nullif there is no actual target instance - 抛出:
BeansException
destroy
public void destroy()
Dispose of targets if necessary; clear ThreadLocal.
getInvocationCount
public int getInvocationCount()
从接口复制的说明:ThreadLocalTargetSourceStatsReturn the number of client invocations.
getHitCount
public int getHitCount()
从接口复制的说明:ThreadLocalTargetSourceStatsReturn the number of hits that were satisfied by a thread-bound object.- 指定者:
getHitCount在接口中ThreadLocalTargetSourceStats
getObjectCount
public int getObjectCount()
从接口复制的说明:ThreadLocalTargetSourceStatsReturn the number of thread-bound objects created.
getStatsMixin
public IntroductionAdvisor getStatsMixin()
Return an introduction advisor mixin that allows the AOP proxy to be cast to ThreadLocalInvokerStats.
