在Java中定义Avro模式，如何处理时间戳或日期值？

{
  "type": "record",
  "name": "TimestampRecord",
  "fields": [
    {
      "name": "timestamp",
      "type": "long"
    }
  ]
}

import org.apache.avro.Schema;
import org.apache.avro.generic.GenericData;
import org.apache.avro.generic.GenericRecord;

import java.util.Date;

public class AvroTimestampExample {
    public static void main(String[] args) {
        Schema schema = new Schema.Parser().parse("your_avro_schema_definition");

        GenericRecord record = new GenericData.Record(schema);
        record.put("timestamp", new Date().getTime());

        // Perform operations with the Avro record
        // ...

        // Convert Avro record to JSON or binary format
        // ...
    }
}

{
  "type": "record",
  "name": "DateRecord",
  "fields": [
    {
      "name": "date",
      "type": "int"
    }
  ]
}

import org.apache.avro.Schema;
import org.apache.avro.generic.GenericData;
import org.apache.avro.generic.GenericRecord;

import java.time.LocalDate;

public class AvroDateExample {
    public static void main(String[] args) {
        Schema schema = new Schema.Parser().parse("your_avro_schema_definition");

        GenericRecord record = new GenericData.Record(schema);
        record.put("date", LocalDate.now().toEpochDay());

        // Perform operations with the Avro record
        // ...

        // Convert Avro record to JSON or binary format
        // ...
    }
}
