Package org.apache.tomcat.dbcp.dbcp2.datasources

Class InstanceKeyDataSource

java.lang.Object
org.apache.tomcat.dbcp.dbcp2.datasources.InstanceKeyDataSource
All Implemented Interfaces:
Serializable, AutoCloseable, Wrapper, Referenceable, CommonDataSource, DataSource
Direct Known Subclasses:
PerUserPoolDataSource, SharedPoolDataSource
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.

    • close

      public abstract void close() throws SQLException
      Closes the connection pool being maintained by this datasource.
      Specified by:
      close in interface AutoCloseable
      Throws:
      SQLException

    • getConnection

      public Connection getConnection() throws SQLException
      Attempts to establish a database connection.
      Specified by:
      getConnection in interface DataSource
      Throws:
      SQLException

    • getConnection

      public Connection getConnection(String userName, String userPassword) throws SQLException
      Attempts to retrieve a database connection using getPooledConnectionAndInfo(String, String) with the provided user name and password. The password on the PooledConnectionAndInfo instance returned by getPooledConnectionAndInfo is compared to the password parameter. 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, the PooledConnectionAndInfo instance retrieved with the old password is destroyed and the getPooledConnectionAndInfo is repeatedly invoked until a PooledConnectionAndInfo instance with the new password is returned.

      getConnection in interface DataSource
