如何在谷歌应用程序引擎中设置事务的默认提交？
ObjectifyBookShelfDAO transactionalDao = new ObjectifyBookShelfDAO(true);
transactionDao.removeThis(item);
// Its get removed only after i commit
// Perform some operations
transactionDao.ofy().getTxn().commit();
有一种情况，我希望立即删除该对象...我该怎么做..
ObjectifyBookShelfDAO transactionalDao = new ObjectifyBookShelfDAO(true);
transactionDao.removeThis(item);
// Its get removed only after i commit
// Perform some operations
transactionDao.ofy().getTxn().commit();
There is a scenario where in i want this object to be removed on instant... How do i do this ..

您似乎正在使用 objectify-appengine。如objectify 事务文档所述，如果您致电
removeThis()在事务之外，它将立即发生。作为替代方案，objectify 允许您混合调用内置 低级 Java 数据存储 API。您可以使用它并调用
DatastoreService.delete()而不传递事务。it looks like you're using objectify-appengine. as the objectify transaction docs describe, if you make your call to
removeThis()outside of a transaction, it will happen immediately.as an alternative, objectify lets you mix in calls to the built in low level java datastore API. you could use that and call
DatastoreService.delete()without passing a transaction.
