Spring Data MongoDB更新自定义字段

Question

I have an _id of mongodb object and want to update only a specific field in DB. Is there a way not to get the entire object with findone(id) then set required field and save to mongodb again? I want something like sql update mechanism which didn't find in mongodb yet. I use java Spring data.

Answer 1

I am assuming that you are using spring-data-mongodb ,

MongoTemplate has convenient methods for update / upsert .
