The query : db.getCollection('homework').find({},{"field1.field2":1}) work well in robomongo. When I use spring @query like this: @Query(value = "{}", fields="{ ?0 : 1}") public List findByDoRecordKey(String key); // key is "field1.field2"

It is not work well. And it works like: db.getCollection('homework').find({},{"field1":1}) removed the field2.
