如何通过JPA在MySQL中存储HashMap <String，QuestionWrapper>，其中QuestionWrapper是带有多个List <Question>的对象

如何解决如何通过JPA在MySQL中存储HashMap <String，QuestionWrapper>，其中QuestionWrapper是带有多个List <Question>的对象

public class QuestionWrapper {

    private Set<Qbank> tfQuestionSetMain = new HashSet<>();
    private Set<Qbank> fibQuestionSetMain = new HashSet<>();
    private Set<Qbank> etfQuestionSetMain = new HashSet<>();
    private Set<Qbank> mtfQuestionSetMain = new HashSet<>();
    private Set<Qbank> mcQuestionSetMain = new HashSet<>();
    private Set<Qbank> saQuestionSetMain = new HashSet<>();
    private Set<Qbank> laQuestionSetMain = new HashSet<>();

    private Set<Qbank> tfQuestionSetRe = new HashSet<>();
    private Set<Qbank> fibQuestionSetRe = new HashSet<>();
    private Set<Qbank> etfQuestionSetRe = new HashSet<>();
    private Set<Qbank> mtfQuestionSetRe = new HashSet<>();
    private Set<Qbank> mcQuestionSetRe = new HashSet<>();
    private Set<Qbank> saQuestionSetRe = new HashSet<>();
    private Set<Qbank> laQuestionSetRe = new HashSet<>();
    private QpData qpData;

    // getters & setters
}

我显然可以将每个Qbank对象存储在数据库中，然后构造QuestionWrapper，最后构造一个hashmap。但是我想要一种更简单，更省力的方式来存储整个哈希图，并在需要时进行检索。
