Max value from field Spring Data and Mongodb -
i want calculate maximum value of field code within entity "user", use spring data, have seen code as: ".find({}).sort({"updatetime" : -1}).limit(1)" but not know how integrate "repository" @query or equivalent solution, return maximum value of said field. can me? thank you. you can write custom method repository. example have: public interface userrepository extends mongorepository<user, string>, userrepositorycustom { ... } additional methods repository: public interface userrepositorycustom { user maxuser(); } and implementation of it: public class userrepositoryimpl implements userrepositorycustom { @autowired private mongotemplate mongotemplate; @override public user maxuser() { final query query = new query() .limit(1) .with(new sort(sort.direction.desc, "updatetime")); return mongotemplate.findone(query, user.class) } } ...
