Chapter 3. Migrating Apicurio Registry client applications You must review your existing Apicurio Registry client applications to ensure that the Maven dependencies and Java client configuration meet the new requirements for version 2.x. For example, this includes new Maven dependencies for the Apicurio Registry Java REST client libraries or Kafka client serializer/deserializer (Serdes) libraries. You must also update your Java application configuration with the new registry v2 API path. Prerequisites Existing Apicurio Registry 1.1 Java client application or Kafka client producer and consumer Java applications with SerDes Procedure If you are using the Apicurio Registry Java REST client, you must change the Maven dependencies for the Apicurio Registry Java client libraries, which have been repackaged in version 2.x: <dependency> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-client</artifactId> <version>2.6.5.Final-redhat-00001</version> </dependency> In your Java client application, you must change your registry URL configuration, from pointing to the existing v1 API path to the new v2 path. For example: public class ClientExample { private static final RegistryRestClient client; public static void main(String[] args) throws Exception { // Create a registry client String registryUrl = "https://new-registry.my-company.com/apis/registry/v2"; RegistryClient client = RegistryClientFactory.create(registryUrl); } } You can find more details on the Java client in the Red Hat build of Apicurio Registry User Guide . If you are using the Apicurio Registry SerDes libraries, you must change the Maven dependencies, which have been repackaged in version 2.x. In Apicurio Registry 1.1, the SerDes libraries were all provided with only one Maven dependency: <dependency> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-utils-serde</artifactId> <version>1.3.2.Final-redhat-00002</version> </dependency> In Apicurio Registry 2.x, the SerDes libraries have been split into three Maven dependencies, one for each supported data format: avro , protobuf , and json schema , depending on your use cases: <dependency> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-serdes-avro-serde</artifactId> <version>2.6.5.Final-redhat-00001</version> </dependency> <dependency> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-serdes-protobuf-serde</artifactId> <version>2.6.5.Final-redhat-00001</version> </dependency> <dependency> <groupId>io.apicurio</groupId> <artifactId>apicurio-registry-serdes-jsonschema-serde</artifactId> <version>2.6.5.Final-redhat-00001</version> </dependency> In your Kafka producer and consumer Java applications, you must change your registry URL configuration from pointing to the existing v1 API path to the new v2 path. For example: Existing registry v1 API path : props.putIfAbsent(AbstractKafkaSerDe.REGISTRY_URL_CONFIG_PARAM, "http://old-registry.my-company.com/api"); New registry v2 API path : props.putIfAbsent(SerdeConfig.REGISTRY_URL, "http://new-registry.my-company.com/apis/registry/v2"); The refactored SerDes libraries also include other important changes to configuration properties. For more details on SerDes configuration, see the Red Hat build of Apicurio Registry User Guide .
