Answer 1

You don't need to call DataSource's close() for every connection:

Shutdown the DataSource and its associated pool.

It's defined only for application termination:

close() is essential at application termination

You should continue working with the pool, notice you are closing (correctly) the connection with try with resources

try (Connection connection = dataSource.getConnection()
