Spring data MongoDb: MappingMongoConverter remove _class

Question

The default MappingMongoConverter adds a custom type key (\"_class\") to each object in the database. So, if I create a Person:

package my.d

@Configuration
public class MongoConfig {

    @Value("${spring.data.mongodb.database}")
    private String database;

    @Value("${spring.data.mongodb.host}")
    private String host;

    public @Bean MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(new MongoClient(host), database);
    }

    public @Bean MongoTemplate mongoTemplate() throws Exception {

        MappingMongoConverter converter = new MappingMongoConverter(new DefaultDbRefResolver(mongoDbFactory()),
                new MongoMappingContext());
        converter.setTypeMapper(new DefaultMongoTypeMapper(null));

        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory(), converter);

        return mongoTemplate;

    }

}
