Is there any way to update whole Entity in MongoDB?

Question

I'm using Spring Data MongoDB and currently I'm wondering if there's any way to update whole entity like mongoTemplate.update(entityObject)? Because the usual way is to update properties one-by-one.. PS Code written in Java.

Answer 1

You can use the save() method on the entity.

Answer 2

Right - the save() method does a full document replace. Because the database is schema-less, the concept of fields doesn't really exist apart from your document.
