public abstract class InstanceKeyDataSource extends Object implements DataSource, Referenceable, Serializable, AutoCloseable
The base class for SharedPoolDataSource
and PerUserPoolDataSource
. Many of the
configuration properties are shared and defined here. This class is declared public in order to allow particular
usage with commons-beanutils; do not make direct use of it outside of commons-dbcp2.
A J2EE container will normally provide some method of initializing the DataSource
whose attributes are
presented as bean getters/setters and then deploying it via JNDI. It is then available to an application as a source
of pooled logical connections to the database. The pool needs a source of physical connections. This source is in the
form of a ConnectionPoolDataSource
that can be specified via the setDataSourceName(String)
used
to lookup the source via JNDI.
Although normally used within a JNDI environment, A DataSource can be instantiated and initialized as any bean. In
this case the ConnectionPoolDataSource
will likely be instantiated in a similar manner. This class
allows the physical source of connections to be attached directly to this pool using the
setConnectionPoolDataSource(ConnectionPoolDataSource)
method.
The dbcp package contains an adapter, DriverAdapterCPDS
, that can be
used to allow the use of DataSource
's based on this class with JDBC driver implementations that do not
supply a ConnectionPoolDataSource
, but still provide a Driver
implementation.
The package documentation contains an example using Apache Tomcat and JNDI and it also contains a non-JNDI example.
