Class DriverManagerDataSource
- All Implemented Interfaces:
- Wrapper,- CommonDataSource,- DataSource
- Direct Known Subclasses:
- SingleConnectionDataSource
DataSource interface,
 configuring the plain old JDBC DriverManager 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.
Useful for test or standalone environments outside of a Jakarta EE container, either
 as a DataSource bean in a corresponding ApplicationContext or in conjunction with
 a simple JNDI environment. Pool-assuming Connection.close() calls will
 simply close the Connection, so any DataSource-aware persistence code should work.
 
NOTE: Within special class loading environments such as OSGi, this class
 is effectively superseded by SimpleDriverDataSource due to general class
 loading issues with the JDBC DriverManager that be resolved through direct Driver
 usage (which is exactly what SimpleDriverDataSource does).
 
In a Jakarta EE 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.
 For tests, you can then either set up a mock JNDI environment through Spring's
 org.springframework.mock.jndi.SimpleNamingContextBuilder, or switch the
 bean definition to a local DataSource (which is simpler and thus recommended).
 
This DriverManagerDataSource class was originally designed alongside
 Apache Commons DBCP
 and C3P0, featuring bean-style
 BasicDataSource/ComboPooledDataSource classes with configuration
 properties for local resource setups. For a modern JDBC connection pool, consider
 HikariCP instead,
 exposing a corresponding HikariDataSource instance to the application.

Method Details- 
setDriverClassNameSet the JDBC driver class name. This driver will get initialized on startup, registering itself with the JDK's DriverManager.NOTE: DriverManagerDataSource is primarily intended for accessing pre-registered JDBC drivers. If you need to register a new driver, consider using SimpleDriverDataSourceinstead. Alternatively, consider initializing the JDBC driver yourself before instantiating this DataSource. The "driverClassName" property is mainly preserved for backwards compatibility, as well as for migrating between Commons DBCP and this DataSource.
