java.lang.Objectorg.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
org.springframework.jdbc.support.nativejdbc.CommonsDbcpNativeJdbcExtractor
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.
Tested against Commons DBCP 1.1 and 1.2, but should also work with 1.0. Before Commons DBCP 1.1, DelegatingCallableStatement and DelegatingResultSet have not offered any means to access underlying delegates; consequently, getNativeCallableStatement and getNativeResultSet will not work with 1.0.
