使用jdbc在google cloud sql中连接池

I am trying to develop an application using google cloud sql and cloud endpoints , from the google cloud sql documentation i observed that the connector for google cloud sql does not provide any connection pooling mechanism , i tried searching online to get any possible tutorial or documentation that provides a pooling mechanism but no result , The google documentation just states that you should close connections in the finally block without any connection pooling configuration , I also came across pooling libraries like BoneCp, TomcatDbCp , i'm considering using those options but im not sure about their compatibility with google cloud sql . My front end is a web application and pooling is a must for my application , Please any thoughts or suggestions are welcomed .I am trying to develop an application using goo
