You can't update particular field in document using MongoRepository, because MongoRepository overwrites whole document. You should use MongoTemplate, as explained in other answer.

However, if you really want to update a particular field using MongoRepository, then:

  1. Fetch whole document that you want to update
  2. Set the new value to a particular field
  3. Save whole document.

Example:

MyDocument myDocumentToUpdate = myDocumentRepository.findById(documentId);
myDocumentToUpdate.setMyField(myNewValue);
myDocumentRepository.save(myDocumentToUpdate);

You can update specific field by below code:

Query query1 = new Query(Criteria.where("id").is("123"));
Update update1 = new Update();
update1.set("available", false);
mongoTemplate.updateFirst(query1, update1, Customer.class);
