How I do rollback with spring roo?

Question

I'm trying to find a method that allows me to do a rollback when one of the elements of a list fails for a reason within the business rules established (ie: when throw my customize exception)

Example, (the idea is not recording anything if one element in list fails)

public class ControlSaveElement {

 public void saveRecords(List<MyRecord> listRecords) {

  Boolean status = true;

  foreach(MyRecord element: listRecords) {
     // Here is business rules
     if(element.getStatus() == false) {
        // something
        status = false;
     }
     element.persist();
  }

  if(status == false) {
     // I need to do roll back from all elements persisted before
  }
 }

...
}

Any idea? I'm working with Roo 1.2.2..

How about creating a new static method in the MyRecord entity:

@Transactional
public static void saveMyRecordsList(List<MyRecord> listRecords) {

  boolean persistAll = true;

  foreach(MyRecord element: listRecords) {
     if(element.getStatus() == false) {
        persistAll = false;
     }
  }

  if (persistAll) {
      foreach(MyRecord element: listRecords) {
         entityManager().persist(element);
      }
  }
 }

This may be more efficient than persisting elements and having to roll them back?
