如何使用Spring Data和MongoDB更新Object？

我只是做一个template.save()？

  public Person update( String id,String Name ) 
    {
        logger.debug("Retrieving an existing person");
        // Find an entry where pid matches the id

        Query query = new Query(where("pid").is(id));
        // Execute the query and find one matching entry
        Person person = mongoTemplate.findOne("mycollection",query,Person.class);

        person.setName(name);
        /**
        * How do I update the database
        */

        return person;
    }
