public class SimpleDriverDataSource extends AbstractDriverBasedDataSource
DataSource
interface,
configuring a plain old JDBC Driver
via bean properties, and returning
a new Connection
from every getConnection
call.
NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call.
In a J2EE container, it is recommended to use a JNDI DataSource provided by
the container. Such a DataSource can be exposed as a DataSource bean in a Spring
ApplicationContext via JndiObjectFactoryBean
,
for seamless switching to and from a local DataSource bean like this class.
If you need a "real" connection pool outside of a J2EE container, consider Apache's Jakarta Commons DBCP or C3P0. Commons DBCP's BasicDataSource and C3P0's ComboPooledDataSource are full connection pool beans, supporting the same basic properties as this class plus specific settings (such as minimal/maximal pool size etc).
