Interface ConnectionProxy

All Superinterfaces:

java.sql.Connection, java.sql.Wrapper

public interface ConnectionProxy
extends java.sql.Connection

Subinterface of Connection to be implemented by Connection proxies. Allows access to the underlying target Connection.

This interface can be checked when there is a need to cast to a native JDBC Connection such as Oracle's OracleConnection. Spring's NativeJdbcExtractorAdapter automatically detects such proxies before delegating to the actual unwrapping for a specific connection pool.

1.1
