How do I update Object with Spring Data and MongoDB?

How do I update Object with Spring Data and MongoDB?

do I just do a 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;
    }

Below code is the equivalent implementation using MongoTemplate for update operation.

public Person update(Person person){
        Query query = new Query();
        query.addCriteria(Criteria.where("id").is(person.getId()));
        Update update = new Update();
        update.set("name", person.getName());
        update.set("description", person.getDescription());
        return mongoTemplate.findAndModify(query, update, Person.class);
    }

If you read the javadoc for MongoOperations/MongoTemplate you will see that

save()

performs an:

upsert()

So yes you can just update your object and call save.

You can just use template.save() or repository.save(entity) methods for this. But mongo has also Update object for this operations.

For example:

Update update=new Update();
update.set("fieldName",value);
mongoTemplate.update**(query,update,entityClass);

You could probably do both 'find' and 'update' operations in one line.

mongoTemplate.updateFirst(query,Update.update("Name", name),Person.class)

You can find some excellent tutorials at Spring Data MongoDB Helloworld
