open class SimpleDriverDataSource : AbstractDriverBasedDataSource
Simple implementation of the standard JDBC javax.sql.DataSource interface, configuring a plain old JDBC java.sql.Driver via bean properties, and returning a new java.sql.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 Java 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 org.springframework.jndi.JndiObjectFactoryBean, for seamless switching to and from a local DataSource bean like this class.
If you need a "real" connection pool outside of a Java EE container, consider Apache 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).

open fun getDriver(): Driver
Return the JDBC Driver instance to use. |
|
open fun setDriver(driver: Driver): Unit
Specify the JDBC Driver instance to use. This allows for passing in a shared, possibly pre-configured Driver instance. |
|
open fun setDriverClass(driverClass: Class<out Driver>): Unit
Specify the JDBC Driver implementation class to use. An instance of this Driver class will be created and held within the SimpleDriverDataSource. |
open fun getCatalog(): String
Return the database catalog to be applied to each Connection, if any. |
|
open fun getConnection(): Connection
This implementation delegates to open fun getConnection(username: String, password: String): Connection

|
open fun getConnectionProperties(): Properties
Return the connection properties to be passed to the Driver, if any. |
|
open fun getPassword(): String
Return the JDBC password to use for connecting through the Driver. |
|
open fun getSchema(): String
Return the database schema to be applied to each Connection, if any. |

Return the JDBC username to use for connecting through the Driver. |
|
open fun setCatalog(catalog: String): Unit
Specify a database catalog to be applied to each Connection. |
|
open fun setConnectionProperties(connectionProperties: Properties): Unit
Specify arbitrary connection properties as key/value pairs, to be passed to the Driver. Can also contain "user" and "password" properties. However, any "username" and "password" bean properties specified on this DataSource will override the corresponding connection properties. |

open fun setPassword(password: String): Unit
Set the JDBC password to use for connecting through the Driver. |

open fun setSchema(schema: String): Unit
Specify a database schema to be applied to each Connection. |
|
open fun setUrl(url: String): Unit
Set the JDBC URL to use for connecting through the Driver. |
|
open fun setUsername(username: String): Unit
Set the JDBC username to use for connecting through the Driver. |
