     ...
     template.inTransaction(() -> doSoemStaff())

        public <T> T inTransaction​(TxAction<T> action)
        Wraps provided action with unit of work and transaction. If called under already started transaction then action will be called directly.

        NOTE: If unit of work was started manually (using UnitManager, but without transaction started, then action will be simply executed without starting transaction. This was done for rare situations when logic must be performed without transaction and transaction annotation will simply indicate unit of work.

        Type Parameters:
        T - return type
        Parameters:
        action - action to execute
        Returns:
        action result
