如何在avro模式中创建包含字符串数组的对象？

{
  "type": "record",
  "name": "UserInterests",
  "fields": [
    {
      "name": "userId",
      "type": "string"
    },
    {
      "name": "interests",
      "type": {
        "type": "array",
        "items": "string"
      }
    }
  ]
}

import org.apache.avro.Schema;
import org.apache.avro.file.DataFileReader;
import org.apache.avro.file.DataFileWriter;
import org.apache.avro.generic.GenericData;
import org.apache.avro.generic.GenericDatumReader;
import org.apache.avro.generic.GenericDatumWriter;
import org.apache.avro.generic.GenericRecord;

import java.io.File;

public class AvroExample {
    public static void main(String[] args) throws Exception {
        // 定义模式
        String schemaString = "{\"type\":\"record\",\"name\":\"UserInterests\",\"fields\":[{\"name\":\"userId\",\"type\":\"string\"},{\"name\":\"interests\",\"type\":{\"type\":\"array\",\"items\":\"string\"}}]}";
        Schema.Parser parser = new Schema.Parser();
        Schema schema = parser.parse(schemaString);

        // 创建一个GenericRecord实例
        GenericRecord user = new GenericData.Record(schema);
        user.put("userId", "12345");
        user.put("interests", new String[]{"sports", "music", "reading"});

        // 写入文件
        try (DataFileWriter<GenericRecord> writer = new DataFileWriter<>(new GenericDatumWriter<>(schema))) {
            writer.create(schema, new File("users.avro"));
            writer.append(user);
        }

        // 读取文件
        try (DataFileReader<GenericRecord> reader = new DataFileReader<>(new File("users.avro"), new GenericDatumReader<>())) {
            for (GenericRecord record : reader) {
                System.out.println(record.get("userId") + ": " + record.get("interests"));
            }
        }
    }
}
