Google App Engine - 已删除的实体未被删除

Question

I'm trying to delete an entity in google datastore

String keyValue = "someValue";
Key tweetKey = KeyFactory.createKey("tweetKey", keyValue);
Entity someEntity = new Entity(tweetKey);

Entity getEntity = datastore.get(tweetKey);
datastore.delete(tweetKey);
getEntity = datastore.get(tweetKey);
if(getEntity != null)
{
   //This happens
   System.out.println("Something wrong");
}

The entity are not deleted, and it something wrong as the output

Edit 1: I didn't copy and paste from the original code, because there are a lot of other logic in between getting and using values from the entity.

Answer 1

You are deleting a different key than the one you are checking.

You are deleting the tweetKey and checking the tweetkey (notice the capital K in the first one). If this snippet is a copy paste from your original then that's the mistake.

Answer 2

确保您没有活动的事务，如果您确实提交了事务。
