public abstract class AbstractPoolingTargetSource
extends AbstractPrototypeBasedTargetSource
implements PoolingConfig, DisposableBean
```
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. This abstract base class is independent of concrete pooling technology; see the subclass CommonsPool2TargetSource for a concrete example.
Subclasses must implement the getTarget() and releaseTarget(java.lang.Object) methods based on their chosen object pool. The AbstractPrototypeBasedTargetSource.newPrototypeInstance() method inherited from AbstractPrototypeBasedTargetSource can be used to create objects in order to put them into the pool.
Subclasses must also implement some of the monitoring methods from the PoolingConfig interface. The getPoolingConfigMixin() method makes these stats available on proxied objects through an IntroductionAdvisor.
This class implements the DisposableBean interface in order to force subclasses to implement a DisposableBean.destroy() method, closing down their object pool.

public AbstractPoolingTargetSource()
```

  - setMaxSize
```
public void setMaxSize(int maxSize)
```
    Set the maximum size of the pool. Default is -1, indicating no size limit.
  - getMaxSize
```
public int getMaxSize()
```
    Return the maximum size of the pool.
    指定者:
    getMaxSize 在接口中 PoolingConfig
  - setBeanFactory
```
public final void setBeanFactory(BeanFactory beanFactory)
                          throws BeansException
```
    从类复制的说明: AbstractBeanFactoryBasedTargetSource
    Set the owning BeanFactory. We need to save a reference so that we can use the getBean method on every invocation.
    指定者:
    setBeanFactory 在接口中 BeanFactoryAware
    覆盖:
    setBeanFactory 在类中 AbstractPrototypeBasedTargetSource
    参数:
    beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.
    抛出:
    BeansException - in case of initialization errors
    另请参阅:
    BeanInitializationException
  - createPool
```
protected abstract void createPool()
                            throws Exception
```
    Create the pool.
    抛出:
    Exception - to avoid placing constraints on pooling APIs
  - getTarget
```
@Nullable
public abstract Object getTarget()
                          throws Exception
```
    Acquire an object from the pool.
    指定者:
    getTarget 在接口中 TargetSource
    返回:
    an object from the pool
    抛出:
    Exception - we may need to deal with checked exceptions from pool APIs, so we're forgiving with our exception signature
  - releaseTarget
```
public abstract void releaseTarget(Object target)
                            throws Exception
```
    Return the given object to the pool.
    指定者:
    releaseTarget 在接口中 TargetSource
    覆盖:
    releaseTarget 在类中 AbstractBeanFactoryBasedTargetSource
    参数:
    target - object that must have been acquired from the pool via a call to getTarget()
    抛出:
    Exception - to allow pooling APIs to throw exception
    另请参阅:
    getTarget()
  - getPoolingConfigMixin
```
public DefaultIntroductionAdvisor getPoolingConfigMixin()
```
    Return an IntroductionAdvisor that providing a mixin exposing statistics about the pool maintained by this object.
