spring事務管理預設復原異常

@Transactional(rollbackfor = "xxx.xxx.xException")

可以設定當抛出哪些異常時進行復原，那麼當不設定此屬性時，Spring事務管理預設對哪些異常復原呢？

通過檢視Spring的源碼，可以找到

package org.springframework.transaction.interceptor;

public class DefaultTransactionAttribute extends DefaultTransactionDefinition implements TransactionAttribute {
      /**
	 * The default behavior is as with EJB: rollback on unchecked exception.
	 * Additionally attempt to rollback on Error.
	 * <p>This is consistent with TransactionTemplate's default behavior.
	 */
	@Override
	public boolean rollbackOn(Throwable ex) {
		return (ex instanceof RuntimeException || ex instanceof Error);
	}
}
           

即RuntimeException和Error
