MongoTemplate：删除从find查找返回的元素列表

Question

I am calling MongoTemplate.find(query, type) which returns a List<T> . My question, how do I remove all elements in the list from the DB Collection in one DB call. I know I could create a Query manually using id if I know the structure of T but what if I don't know what T is.

MongoTemplate has a remove method that I can pass T . What I need is the equivalent removeAll(Collection<T> items, Class<T> type)

EDIT per answer

I need to process each element and determine which ones to remove so I cannot simply pass the Query to remove .

Answer 1

Instead of calling find(Query, Class) and then remove all returned documents (a Collection or one-by-one), you can simply call remove(Query, Class) . It's much better that way since you don't have to return all documents to the client, but issue a remove query in the DB itself.
