Java Spring数据Rest超出了GC开销

已编辑

有2个实体用户和RefSecQuestion链接如下-

内部用户：这已更改为渴望解决问题

内部问题:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "refSecQuestion")
public Set<User> getUsers() {
    return this.users;
} 

@OneToMany（fetch=FetchType.LAZY，mappedBy=“refSecQuestion”）
公共集getUsers（）{
将此文件返回给用户；
} 

访问URL-/api/refSecQuestions或/api/users/2/refSecQuestions时会出现此错误-
