public class SingleConnectionFactory extends DelegatingConnectionFactory implements DisposableBean
getConnection
calls, and ignores calls to
Connection.close()
.
Useful for testing and standalone environments, to keep using the same Connection for multiple CciTemplate calls, without having a pooling ConnectionFactory, also spanning any number of transactions.
You can either pass in a CCI Connection directly, or let this factory lazily create a Connection via a given target ConnectionFactory.
