我有一些实体具有懒惰的一对多关系(为简洁省略了逻辑):

@Entity
class A{
    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "a_pk", nullable = false)
    List<B> blist = new ArrayList<>();

    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "a_pk", nullable = false)
    List<C> clist = new ArrayList<>();

    @Column(name = "natural_identifier", nullable = false)
    private String id;
}

@Entity
class B{
}

@Entity
class C{
    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "c_pk", nullable = false)
    List<D> dlist = new ArrayList<>();

    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = …

我想配置Typesafe Activator,它的捆绑工具不使用我的用户主目录 - 我的意思是~/.activator(配置？),~/.sbt(sbt配置？),特别是~/.ivy2我想在两个操作系统之间共享.Typesafe"文档"没什么帮助.

请帮助Windows和Linux.
