ConfluentSchemaRegistry中的JSONSchema数组管理问题。

在Confluent Schema Registry中处理JSON Schema中的数组时，可以使用JsonSchema类的ArrayList和mapWith(ArrayList)方法。以下示例代码演示了如何在Confluent Schema Registry中使用这些方法来管理JSON Schema数组：

import io.confluent.kafka.schemaregistry.client.SchemaRegistryClient;
import io.confluent.kafka.schemaregistry.client.rest.RestService;
import io.confluent.kafka.schemaregistry.client.SchemaMetadata;
import io.confluent.kafka.schemaregistry.client.CachedSchemaRegistryClient;
import io.confluent.kafka.serializers.AbstractKafkaAvroSerializerConfig;
import io.confluent.kafka.serializers.KafkaAvroSerializer;
import io.confluent.kafka.serializers.subject.RecordNameStrategy;

import org.everit.json.schema.Schema;
import org.everit.json.schema.loader.SchemaLoader;
import org.everit.json.schema.ValidationException;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

public class ConfluentSchemaRegistry {

    public static void main(String[] args) throws Exception {

        // Connect to the Confluent Schema Registry
        SchemaRegistryClient client = new CachedSchemaRegistryClient("http://localhost:8081", 10);

        // Define a schema
        String schema = "{\n" +
                        "  \"$schema\": \"http://json-schema.org/draft-07/schema#\",\n" +
                        "  \"type\": \"object\",\n" +
                        "  \"properties\": {\n" +
                        "    \"users\": {\n" +
                        "      \"type\": \"array\",\n" +
                        "      \"items\": {\n" +
                        "        \"type\": \"object\",\n" +
                        "        \"properties\": {\n" +
                        "          \"name\": {\n" +
                        "            \"type\": \"string\"\n" +
                        "          },\n" +
                        "          \"age\": {\n" +
                        "            \"type\": \"integer\"\n" +
                        "          }\n" +
                        "        },\n" +
                        "        \"required\": [\n" +
                        "          \"name\"\n" +
                        "        ]\n" +
                        "      }\n"
