Interface ConnectionProxy

All Superinterfaces:

AutoCloseable, Connection, Wrapper

public interface ConnectionProxy
extends 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. Alternatively, all such connections also support JDBC 4.0's Wrapper.unwrap(java.lang.Class<T>).
