我们在 A <-> B <-> C“层次结构”中有三个具有双向多对多映射的实体，就像这样（当然是简化的）：

@Entity
Class A {
  @Id int id;
  @JoinTable(
    name = "a_has_b",
    joinColumns = {@JoinColumn(name = "a_id", referencedColumnName = "id")},
    inverseJoinColumns = {@JoinColumn(name = "b_id", referencedColumnName = "id")})
  @ManyToMany
  Collection<B> bs;
}

@Entity
Class B {
  @Id int id;
  @JoinTable(
    name = "b_has_c",
    joinColumns = {@JoinColumn(name = "b_id", referencedColumnName = "id")},
    inverseJoinColumns = {@JoinColumn(name = "c_id", referencedColumnName = "id")})
  @ManyToMany(fetch=FetchType.EAGER,
    cascade=CascadeType.MERGE,CascadeType.PERSIST,CascadeType.REFRESH})
  @org.hibernate.annotations.Fetch(FetchMode.SUBSELECT)
  private Collection<C> cs;
  @ManyToMany(mappedBy = "bs", fetch=FetchType.EAGER,
    cascade={CascadeType.MERGE,CascadeType.PERSIST,  CascadeType.REFRESH})
  @org.hibernate.annotations.Fetch(FetchMode.SUBSELECT)
  private Collection<A> as; …

寻找用于解析JavaScript的Java/JDK API(包括Nashorn Extensions)我偶然发现了这个Gist,根据内联评论需要运行JDK 9.有没有可靠的方法在JDK 8的当前版本或计划版本上实现相同的目标？

是否可以仅导出Web内容结构和/或模板？
