In this post under Apache Pool, I will show with example how to create a synchronized object pool factory.

Below is the complete main class for your reference

Main class

package package17;

import org.apache.commons.pool2.PoolUtils;
import org.apache.commons.pool2.PooledObjectFactory;

public class StringBufferPoolExample17 {
    public static void main(String[] args) {
        StringBufferPooledObjectFactory stringBufferPooledObjectFactory = new StringBufferPooledObjectFactory();
        PooledObjectFactory<StringBuffer> threadSafePooledObjectFactory = PoolUtils.synchronizedPooledFactory(stringBufferPooledObjectFactory);

        System.out.println(threadSafePooledObjectFactory);
    }
}

In the above code, at line 8, I create an instance of “StringBufferePooledObjectFactory”.

At line 9 I create an instance of synchronized pool factory from the instance created at line 8 and using “PoolUtils” “synchronizedPooledFactory” method.

I pass the instance created at line 8 as an argument to “PoolUtils” “synchronizedPooledFactory” method.

In this way we can create a synchronized object pool factory.
