Java 外键引用spring引导中的主键

我正在添加MCQ问题、选项和答案

共有三个表

问题

、

选项

和

答案

下面是我的数据库模式

questionId（问题表）是questionId引用的主键（选项表）是外键

questionId（问题表）是主键，questionId（答案表）是外键

optionId（选项表）是optionId（答案表）是外键所引用的主键

我无法链接主键和外键-请帮助我改进

问题表：

@Entity
@Table(name = "mcq_question")
public class Question {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@JoinColumn (name = "questionId")
private Long questionId;

@Column(nullable = false)
private String question;

@OneToOne(fetch = FetchType.LAZY)
@JoinTable( name = "Answer", joinColumns = @JoinColumn ( name = "question_id"), inverseJoinColumns = @JoinColumn( name = "option_id"))
private List <Option> options;

@OneToMany(mappedBy = "questionId", cascade = CascadeType.ALL)
private Set<Option> option;

public Question() { }

public Long getMcqId() {
    return questionId;
}

public void setMcqId(Long mcqId) {
    this.questionId = mcqId;
}

public String getQuestion() {
    return question;
}

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

@Override
public String toString() {
    return "SessionMcqModel{" +
            "mcqId=" + questionId +
            ", question='" + question + '\'' +
            '}';
}

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;
    Question question1 = (Question) o;
    return questionId.equals(question1.questionId) &&
            question.equals(question1.question) &&
            options.equals(question1.options) &&
            option.equals(question1.option);
}

@Override
public int hashCode() {
    return Objects.hash(questionId, question, options, option);
}
}

错误：

---

原因：org.hibernate.AnnotationException:@OneToOne或@ManyToOne on com.bluepi.TrainingProject.model.Question.options引用未知实体：java.util.List

问题在于

问题
和
选项之间的关系

@OneToOne(fetch = FetchType.LAZY)
@JoinTable( name = "Answer", joinColumns = @JoinColumn ( name = "question_id"), inverseJoinColumns = @JoinColumn( name = "option_id"))
private List <Option> options;

@OneToOne（fetch=FetchType.LAZY）
@JoinTable（name=“Answer”、joinColumns=@JoinColumn（name=“question\u id”）、inverseJoinColumns=@JoinColumn（name=“option\u id”））
私人名单选择；

您试图将列表映射到不正确的1-1关系，可能需要使用
@OneToMany
注释而不是
@onetomone

@OneToOne(fetch = FetchType.LAZY)
@JoinTable( name = "Answer", joinColumns = @JoinColumn ( name = "question_id"), inverseJoinColumns = @JoinColumn( name = "option_id"))
private List <Option> options;
