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         


        

Answer 1

Here's my annotation, and it works.

@Configuration
public class AppMongoConfig {

    public @Bean
    MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(new Mongo(), "databasename");
    }

    public @Bean
    MongoTemplate mongoTemplate() throws Exception {

        //remove _class
        MappingMongoConverter converter = new MappingMongoConverter(mongoDbFactory(), new MongoMappingContext());
        converter.setTypeMapper(new DefaultMongoTypeMapper(null));

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

        return mongoTemplate;

    }

}
