java - Greendao 无法生成 join dao 导入（ToMany 关系）

Question

Greendao 不生成 ToMany joiner dao 的导入。我怎样才能做到这一点？我正在创建 Book 和 BookStore，尝试通过自定义加入者在书店中保存书籍列表。构建后尝试生成的 Joiner JoinBookStoreWithBookDao 没有导入 BookStoreDao 但存在。

    @ToMany
    @JoinEntity(

            sourceProperty = "bookStoreId",
            targetProperty = "bookId"
    )
    private List<Book> mBooks;

Answer 1

我找到了理由。Joiner 应该在“父母”的包内，他不能在另一个包中。
