Question

我试图保存一个问题选项列表但是没有保存。只保存最后一行。

以下是代码。

@Transactional
public void addQuestionOptions(QuestionOptionsRequest questionOptionsRequest, int questionId) {
    List<QuestionOption> optionList = new ArrayList<>();
    QuestionOption options = new QuestionOption();

    Question question = questionRepository.findByQuestionId(questionId);
    if(question != null) {
        questionOptionsRequest.getQuestionOptions()
                .stream()
                .forEach(option -> {
                    options.setQuestionOption(option.getQuestionOption());
                    options.setQuestion(question);
                    options.setQuestionOptionNumber(option.getQuestionOptionNumber());
                    optionList.add(options);
                });
        questionOptionRepository.saveAll(optionList);
    } 
}

QuestionOption

@Entity
@JsonIgnoreProperties({"question"})
public class QuestionOption {

    @Id
    @GeneratedValue
    private int questionOptionId;

    private int questionOptionNumber;

    private String questionOption;

    public Question getQuestion() {
        return question;
    }

    public void setQuestion(Question question) {
        this.question = question;
    }

    @ManyToOne(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
    private Question question;

    public void setQuestionOptionNumber(int questionOptionNumber)
    {
        this.questionOptionNumber = questionOptionNumber;
    }

    public void setQuestionOption(String questionOption)
    {
        this.questionOption = questionOption;
    }

    public String getQuestionOption()
    {
        return this.questionOption;
    }

    public int getQuestionOptionNumber()
    {
        return this.questionOptionNumber;

    public void setQuestionOptionId(int questionOptionId) {

Answer 1

您只创建了QuestionOption的一个对象

QuestionOption options = new QuestionOption（）;

在每个内部创建此对象。

列表未保存
