Class CommonsDbcpNativeJdbcExtractor

public class CommonsDbcpNativeJdbcExtractor

implements NativeJdbcExtractor

Implementation of the NativeJdbcExtractor interface for the Jakarta Commons DBCP connection pool. Returns the underlying native Connection, Statement, ResultSet etc to application code instead of DBCP's wrapper implementations. The returned JDBC classes can then safely be cast, e.g. to OracleResultSet.

This NativeJdbcExtractor can be set just to allow working with a Commons DBCP DataSource: If a given object is not a Commons DBCP wrapper, it will be returned as-is.

Note: Before Commons DBCP 1.1, DelegatingCallableStatement and DelegatingResultSet have not offered any means to access underlying delegates. Therefore, getNativeCallableStatement and getNativeResultSet will just work with DBCP 1.1. But getNativeResultSet will not be invoked by JdbcTemplate for a wrapped ResultSet anyway, because getNativeStatement/getNativePreparedStatement will already have returned the underlying delegate before.
