@Deprecated
public class CommonsPoolTargetSource
extends AbstractPoolingTargetSource
implements org.apache.commons.pool.PoolableObjectFactory
```
Deprecated.
as of Spring 4.2, in favor of CommonsPool2TargetSource
TargetSource implementation that holds objects in a configurable Apache Commons Pool.
By default, an instance of GenericObjectPool is created. Subclasses may change the type of ObjectPool used by overriding the createObjectPool() method.
Provides many configuration properties mirroring those of the Commons Pool GenericObjectPool class; these properties are passed to the GenericObjectPool during construction. If creating a subclass of this class to change the ObjectPool implementation type, pass in the values of configuration properties that are relevant to your chosen implementation.
The testOnBorrow, testOnReturn and testWhileIdle properties are explicitly not mirrored because the implementation of PoolableObjectFactory used by this class does not implement meaningful validation. All exposed Commons Pool properties use the corresponding Commons Pool defaults.
Compatible with Apache Commons Pool 1.5.x and 1.6. Note that this class doesn't declare Commons Pool 1.6's generic type in order to remain compatible with Commons Pool 1.5.x at runtime.
