Example 1 with DataAccessResourceFailureException

use of cn.taketoday.dao.DataAccessResourceFailureException in project today-infrastructure by TAKETODAY.

       * If useNewConnection is true, then we obtain a non-managed connection so our modifications

       * connection relying on the use of a non-transactional storage engine like MYISAM for the
       * incrementer table. We also use straight JDBC code because we need to make sure that the insert
       * and select are performed on the same connection (otherwise we can't be sure that last_insert_id()
       * returned the correct value).
