Spring ObjectPooling and Thread Blocking

Question

I have Spring CommonsPoolTargetSourcedefined for bean. I am trying to understand how pooling works and when an object returns to a pool.

In particular, if I have a worker who takes the combined object and calls two methods on it:

public class MyWorker {
    @Resource
    Foo pooledFoo;

    void doWork()
    {
        pooledFoo.doStepA();
        pooledFoo.doStepB();
    }
}

From what I see in the tests I ran, it pooledFoo’s not really an instance Foo, but a proxy provided by the pool. The stream in the above form will be as follows:

• The doStepA () on call Fooretrieves the value from the pool (blocking the thread if it is not available),
• doStepA is executed in the pooledFoo file
• When doStepA is complete, the instance pooledFooreturns to the pool
• the control returns to the method doWorkand the method continues
