9.5. Service Registry 常量

您可以使用此处概述的常数，将特定的客户端 SerDe 服务和架构查找策略直接配置为客户端。

或者，您也可在属性文件或属性实例中指定常量。

序列化器/序列化器(SerDe)服务的常量

public abstract class AbstractKafkaSerDe<T extends AbstractKafkaSerDe<T>> implements AutoCloseable {
      protected final Logger log = LoggerFactory.getLogger(getClass());

      public static final String REGISTRY_URL_CONFIG_PARAM = "apicurio.registry.url"; 1
      public static final String REGISTRY_CACHED_CONFIG_PARAM = "apicurio.registry.cached"; 2
      public static final String REGISTRY_ID_HANDLER_CONFIG_PARAM = "apicurio.registry.id-handler"; 3
      public static final String REGISTRY_CONFLUENT_ID_HANDLER_CONFIG_PARAM = "apicurio.registry.as-confluent"; 4

查找策略的常量

public abstract class AbstractKafkaStrategyAwareSerDe<T, S extends AbstractKafkaStrategyAwareSerDe<T, S>> extends AbstractKafkaSerDe<S> {
      public static final String REGISTRY_ARTIFACT_ID_STRATEGY_CONFIG_PARAM = "apicurio.registry.artifact-id"; 1
      public static final String REGISTRY_GLOBAL_ID_STRATEGY_CONFIG_PARAM = "apicurio.registry.global-id"; 2

转换器的常量

public class SchemalessConverter<T> extends AbstractKafkaSerDe<SchemalessConverter<T>> implements Converter {
      public static final String REGISTRY_CONVERTER_SERIALIZER_PARAM = "apicurio.registry.converter.serializer"; 1
      public static final String REGISTRY_CONVERTER_DESERIALIZER_PARAM = "apicurio.registry.converter.deserializer"; 2

Avro 数据供应商的常量

public interface AvroDatumProvider<T> {
      String REGISTRY_AVRO_DATUM_PROVIDER_CONFIG_PARAM = "apicurio.registry.avro-datum-provider"; 1
      String REGISTRY_USE_SPECIFIC_AVRO_READER_CONFIG_PARAM = "apicurio.registry.use-specific-avro-reader"; 2

DefaultAvroDatumProvider (io.apicurio.registry.utils.serde.avro) 1
ReflectAvroDatumProvider (io.apicurio.registry.utils.serde.avro) 2
