Class Overview

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 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).

Public Constructors

public SimpleDriverDataSource ()

Constructor for bean-style configuration.

public SimpleDriverDataSource (Driver driver, String url)

Create a new DriverManagerDataSource with the given standard Driver parameters.

Parameters
driver the JDBC Driver object
url the JDBC URL to use for accessing the DriverManager

public SimpleDriverDataSource (Driver driver, String url, String username, String password)

Create a new DriverManagerDataSource with the given standard Driver parameters.

Parameters
driver the JDBC Driver object
url the JDBC URL to use for accessing the DriverManager
username the JDBC username to use for accessing the DriverManager

public SimpleDriverDataSource (Driver driver, String url, Properties conProps)

Create a new DriverManagerDataSource with the given standard Driver parameters.

Parameters
driver the JDBC Driver object
url the JDBC URL to use for accessing the DriverManager
conProps JDBC connection properties

Public Methods

public Driver getDriver ()

Return the JDBC Driver instance to use.

public void setDriver (Driver driver)

Specify the JDBC Driver instance to use.

This allows for passing in a shared, possibly pre-configured Driver instance.

public void setDriverClass (Class<? extends Driver> driverClass)

Specify the JDBC Driver implementation class to use.

An instance of this Driver class will be created and held within the SimpleDriverDataSource.

Protected Methods

protected Connection getConnectionFromDriver (Properties props)

Obtain a Connection using the given properties.

Template method to be implemented by subclasses.

Parameters
props the merged connection properties
Returns
  • the obtained Connection
Throws
SQLException
