使用Java更改DynamoDB中的时间点值

import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient;
import com.amazonaws.services.dynamodbv2.model.AttributeValue;
import com.amazonaws.services.dynamodbv2.model.UpdateItemRequest;

public class DynamoDBTimeUpdate {
    public static void main(String[] args) {
        // 创建AmazonDynamoDBClient对象
        AmazonDynamoDBClient client = new AmazonDynamoDBClient();

        // 创建UpdateItemRequest对象
        UpdateItemRequest request = new UpdateItemRequest()
                .withTableName("your_table_name")
                .addKeyEntry("id", new AttributeValue("your_item_id"))
                .addAttributeUpdatesEntry("timestamp", new AttributeValue().withN(String.valueOf(System.currentTimeMillis())));

        // 更新DynamoDB中的时间点值
        client.updateItem(request);
    }
}
