N.B. DO NOT USE THIS METHOD DIRECTLY. It is only to be used by the TransactionalMethodInterceptor and the RepositoryConnectionMethodInterceptor Makes a Connection object available from the getConnection() method with either autocomit set to true or false.

Specified by:

newConnection in interface JdbcTxManager

Parameters:

autoCommit - automatically commits after each execute. Set to false to use transactions.

commit
