spring – MongoDB-Escape dots’.’在地图键]

org.springframework.data.mapping.model.MappingException: Map key foo.bar.key 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,会发生这种情况.我们怎么解决这个问题？

这是我的班级

@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();
    }
}

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

/**
 * 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,dot始终被视为一个特殊字符,因此避免使用它很可能会在将来为您节省一些其他麻烦.

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

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

    return mongoConverter;
  }
