Class NonClosingConnectionProxy

java.lang.Object

com.ultikits.ultitools.interfaces.impl.data.NonClosingConnectionProxy

All Implemented Interfaces:

AutoCloseable, Connection, Wrapper

class NonClosingConnectionProxy
extends Object
implements Connection

A Connection wrapper that suppresses close() during transactions.

QueryRunner calls connection.close() after every operation. During a transaction, we must prevent that since the TransactionManager controls the connection lifecycle.

Since:

6.2.0
