datastore_v3.Put()已显式取消

Question

我在我的项目中使用Hibernate + google-Cloud-SQL

它工作得很好，但它变慢了一段时间，当我们进行更多的调用时，它给了我以下异常：

com.google.apphosting.api.ApiProxy$CancelledException: The API call datastore_v3.Put() was explicitly cancelled.

Answer 1

这是因为您已经达到了servlet请求或任务的时间限制，并且您仍然无法使用持久性(数据存储、memcache、云sql、存储)等Google服务。
