Automatic table generation fails with MySQL. I get the exception:
MySQLNonTransientConnectionException: Can't call rollback when
autocommit=true
This exception causes the connection to be closed, and the automatic table
generation fails.
The exception is thrown by the SchemaTool.executeSQL method. I checked the
source code and found that the method calls rollback prior to executing
the SQL statement. The problem is that the method also set autocommit to
true before calling rollback, and this leads to the
MySQLNonTransientConnectionException that causes the connection to be
closed.
Is there any workaround?
The complete exception is:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:
Can't call rollback when autocommit=true
