public class Jdbc4NativeJdbcExtractor
NativeJdbcExtractor
implementation that delegates to JDBC 4.0's
unwrap
method, as defined by Wrapper
.
You will typically need to specify a vendor Connection type
/ Statement type
/ ResultSet type
to extract, since JDBC 4.0 only actually unwraps to a given target type.
Note: Only use this when actually running against a JDBC 4.0 driver, with a
connection pool that supports the JDBC 4.0 API (i.e. at least accepts JDBC 4.0
API calls and passes them through to the underlying driver)! Other than that,
there is no need for connection pool specific setup. As of JDBC 4.0,
NativeJdbcExtractors will typically be implemented for specific drivers
instead of for specific pools (e.g. OracleJdbc4NativeJdbcExtractor
).
