MongoDB转义点'.'在地图键中] [英] MongoDB-Escape dots '.' in map key]

问题描述

地图键codeofproduct包含点，但未配置替换项！确保地图键首先不包含点或配置适当的替换键！

Map key codeofproduct contains dots but no replacement was configured! Make sure map keys don't contain dots in the first place or configure an appropriate replacement!

当我们尝试插入值时，就会发生这种情况.我们该如何解决呢?

When we try to insert value, this happens. How can we solve this?

@Configuration
@EnableMongoRepositories("net.ooo.hepsiburada.**.repository")
@Profile(Constants.SPRING_PROFILE_CLOUD)
public class CloudMongoDbConfiguration extends AbstractMongoConfiguration  {

    private final Logger log = LoggerFactory.getLogger(CloudDatabaseConfiguration.class);

    @Inject
    private MongoDbFactory mongoDbFactory;

    @Bean
    public ValidatingMongoEventListener validatingMongoEventListener() {
        return new ValidatingMongoEventListener(validator());
    }

    @Bean
    public LocalValidatorFactoryBean validator() {
        return new LocalValidatorFactoryBean();
    }

    @Bean
    public CustomConversions customConversions() {
        List<Converter<?, ?>> converterList = new ArrayList<>();;
        converterList.add(DateToZonedDateTimeConverter.INSTANCE);
        converterList.add(ZonedDateTimeToDateConverter.INSTANCE);
        converterList.add(DateToLocalDateConverter.INSTANCE);
        converterList.add(LocalDateToDateConverter.INSTANCE);
        converterList.add(DateToLocalDateTimeConverter.INSTANCE);
        converterList.add(LocalDateTimeToDateConverter.INSTANCE);
        return new CustomConversions(converterList);
    }

    @Override
    protected String getDatabaseName() {
        return mongoDbFactory.getDb().getName();
    }

    @Override
    public Mongo mongo() throws Exception {
        return mongoDbFactory().getDb().getMongo();
    }
}

推荐答案

在使用Spring Data MongoDB时，您将获得以下实例:org.springframework.data.mongodb.core.convert.MappingMongoConverter，默认情况下mapKeyDotReplacement设置为null-这就是为什么您要获取异常的原因

When using Spring Data MongoDB you get an instance of: org.springframework.data.mongodb.core.convert.MappingMongoConverter that has mapKeyDotReplacement set to null by default - that is why you are getting an exception.

您需要创建自己的org.springframework.data.mongodb.core.convert.MappingMongoConverter实例，或者只使用其提供程序setter方法修改现有实例:

You need to either create your own instance of org.springframework.data.mongodb.core.convert.MappingMongoConverter or just modify existing instance using its provider setter method:

/**
 * Configure the characters dots potentially contained in a {@link Map} shall be replaced with. By default we don't do
 * any translation but rather reject a {@link Map} with keys containing dots causing the conversion for the entire
 * object to fail. If further customization of the translation is needed, have a look at
 * {@link #potentiallyEscapeMapKey(String)} as well as {@link #potentiallyUnescapeMapKey(String)}.
 * 
 * @param mapKeyDotReplacement the mapKeyDotReplacement to set
 */
public void setMapKeyDotReplacement(String mapKeyDotReplacement) {
    this.mapKeyDotReplacement = mapKeyDotReplacement;
}

在MongoDB中，点始终被视为特殊字符，因此避免点将很可能在将来为您省去其他麻烦.

In MongoDB, dot is always treated as a special character so avoiding it will most likely save you some other headache in the future.

要覆盖默认的MappingMongoConverter，请添加以下bean声明:

To override default MappingMongoConverter add the following bean declaration:

  @Bean
  public MappingMongoConverter mongoConverter(MongoDbFactory mongoFactory) throws Exception {
    DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoFactory);
    MappingMongoConverter mongoConverter = new MappingMongoConverter(dbRefResolver, mongoMappingContext);
    mongoConverter.setMapKeyDotReplacement(".");

    return mongoConverter;
  }
