Class InstanceKeyDataSource
- All Implemented Interfaces:
Serializable,AutoCloseable,Wrapper,Referenceable,CommonDataSource,DataSource
- Direct Known Subclasses:
PerUserPoolDataSource,SharedPoolDataSource
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.

getConnection
Attempts to establish a database connection.- Specified by:

SQLException
-
getConnection
Attempts to retrieve a database connection usinggetPooledConnectionAndInfo(String, String)with the provided user name and password. The password on thePooledConnectionAndInfoinstance returned bygetPooledConnectionAndInfois compared to thepasswordparameter. If the comparison fails, a database connection using the supplied user name and password is attempted. If the connection attempt fails, an SQLException is thrown, indicating that the given password did not match the password used to create the pooled connection. If the connection attempt succeeds, this means that the database password has been changed. In this case, thePooledConnectionAndInfoinstance retrieved with the old password is destroyed and thegetPooledConnectionAndInfois repeatedly invoked until aPooledConnectionAndInfoinstance with the new password is returned.- Specified by:
