java.lang.Objectorg.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
Abstract adapter class for the NativeJdbcExtractor interface, for simplified implementation of basic extractors. Returns the passed-in JDBC objects on all methods.
getNativeConnection
checks for a ConnectionProxy chain,
for example from a TransactionAwareDataSourceProxy, before delegating to
doGetNativeConnection
for actual unwrapping. You can override
either of the two for a specific connection pool, but the latter is
recommended to participate in ConnectionProxy unwrapping.
The getNativeConnectionFromStatement
method is implemented
to simply delegate to getNativeConnection
with the Statement's
Connection. This is what most extractor implementations will stick to,
unless there's a more efficient version for a specific pool.

ConnectionProxy is used by Spring's TransactionAwareDataSourceProxy and SingleConnectionDataSource. The target connection behind it is typically one from a local connection pool, to be unwrapped by the doGetNativeConnection implementation of a concrete subclass.
