我如何MappingMongoConverter在不更改任何由spring-
data自动配置的mongo-stuff的情况下自定义Spring-Boot-Application（1.3.2.RELEASE）中的？

我当前的解决方案是：

@Configuration
public class MongoConfig {

  @Autowired
  private MongoDbFactory mongoFactory;

  @Autowired
  private MongoMappingContext mongoMappingContext;

  @Bean
  public MappingMongoConverter mongoConverter() throws Exception {
    DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoFactory);
    MappingMongoConverter mongoConverter = new MappingMongoConverter(dbRefResolver, mongoMappingContext);
    //this is my customization
    mongoConverter.setMapKeyDotReplacement("_");
    mongoConverter.afterPropertiesSet();
    return mongoConverter;
  }
}

这是正确的方法还是我要打破一些东西？
还是有一种更简单的方法来设置mapKeyDotReplacement？
