Java 一对多关系和ID生成

我有两节课.

"poll.java."

public class Poll {
    @Id
    @Column(name = "poll_id")
    String pollId;
    String question;
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
    String endDateTime;

    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "poll_id_fk", referencedColumnName = "poll_id")
    List<Choice> choices;
}

和

哦， Select .我本来是.

public class Choice {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "choice_id")
    Long choiceId;
    String text;
    Integer votes;
}

当我创建新的投票时，CHOICE_ID从上次创建的CHOICE_ID的数字开始递增.如何在创建新的轮询时使Choose_id重置其值？

我try 更改策略GenerationType，但似乎没有任何影响.我期待着这样的结果:

[
    {
        "pollId": "MvWRj",
        "question": "poll 2?",
        "endDateTime": "2023-07-09 19:50",
        "choices": [
            {
                **"choiceId": 1,**
                "text": "choice 1",
                "votes": 1
            },
            {
                **"choiceId": 2,**
                "text": "choice 2",
                "votes": 0
            }
        ]
    },
    {
        "pollId": "V838D",
        "question": "poll 1?",
        "endDateTime": "2023-07-09 19:50",
        "choices": [
            {
                **"choiceId": 1,**
                "text": "choice 1",
                "votes": 1
            },
            {
                **"choiceId": 2,**
                "text": "choice 2",
                "votes": 0
            }
        ]
    }
]

鉴于我得到的结果如下:

[
    {
        "pollId": "MvWRj",
        "question": "poll 2?",
        "endDateTime": "2023-07-09 19:50",
        "choices": [
            {
                **"choiceId": 3,**
                "text": "choice 1",
                "votes": 1
            },
            {
                **"choiceId": 4,**
                "text": "choice 2",
                "votes": 0
            }
        ]
    },
    {
        "pollId": "V838D",
        "question": "poll 1?",
        "endDateTime": "2023-07-09 19:50",
        "choices": [
            {
                **"choiceId": 1,**
                "text": "choice 1",
                "votes": 1
            },
            {
                **"choiceId": 2,**
                "text": "choice 2",
                "votes": 0
            }
        ]
    }
]
