Class JsonSchemaKafkaSerializer<T>

  • All Implemented Interfaces:
    io.apicurio.registry.resolver.SchemaParser<com.networknt.schema.JsonSchema,​T>, Closeable, AutoCloseable, org.apache.kafka.common.serialization.Serializer<T>
    public class JsonSchemaKafkaSerializer<T>
extends AbstractKafkaSerializer<com.networknt.schema.JsonSchema,​T>
implements org.apache.kafka.common.serialization.Serializer<T>, io.apicurio.registry.resolver.SchemaParser<com.networknt.schema.JsonSchema,​T>
    An implementation of the Kafka Serializer for JSON Schema use-cases. This serializer assumes that the user's application needs to serialize a Java Bean to JSON data using Jackson. In addition to standard serialization of the bean, this implementation can also optionally validate it against a JSON schema.
