Question

我正在尝试通过Servicestack.Redis将Redis Cache用于MVC应用程序。

Redis仅适用于Key字段（默认Id）。我有以下课程

[DataContract]
public partial class Author_Book
{
    public Author_Book() { }
    public Author_Book(int id, string Title, int AuthorID)
    {
        this.Id = id;
        this.Title = Title;
        this.AuthorId = AuthorID;
    }

    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public int AuthorId { get; set; }
    [DataMember]
    public string Title { get; set; }

    public virtual Author Author { get; set; }
}

[DataContract]
public partial class Author
{
    public Author()
    {
        this.Author_Book = new HashSet<Author_Book>();
    }

    public Author(int id, string name)
    {
        this.Id = id;
        this.Name = name;
        this.Author_Book = new HashSet<Author_Book>();
    }

    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public string Name { get; set; }

    [DataMember]
    public virtual ICollection<Author_Book> Author_Book { get; set; }
}

以下功能进行测试

    public static void ListTest()
    {
        // configure Redis to use AuthorID as ID field for Author_Book entities
        ServiceStack.ModelConfig<Author_Book>.Id(x => x.AuthorId);

        PooledRedisClientManager redisManager = new PooledRedisClientManager("localhost:6379");

        Author auth = new Author(1, "Author-1");
        Author auth2 = new Author(2, "Author-2");

        Author_Book ab1 = new Author_Book(1, "Book-1", 1);
        Author_Book ab2 = new Author_Book(2, "Book-2", 2);
        Author_Book ab3 = new Author_Book(3, "Book-3", 2);

        IList<Author_Book> retList;

        using(IRedisClient rc = redisManager.GetClient())
        {
            // store Authors
            rc.Store<Author>(auth);
            rc.Store<Author>(auth2);

            // store Author Books
            rc.Store<Author_Book>(ab1);
            rc.Store<Author_Book>(ab2);
            rc.Store<Author_Book>(ab3);

            // Get data back from redis
            List<int> ids = new List<int>();
            ids.Add(2);
            retList = rc.GetByIds<Author_Book>(ids);
        }

        foreach(Author_Book ab in retList)
        {
            Console.WriteLine(ab.Title);
        }
        Console.Read();
    }

我在这里要做的是，

而不是使用Id，我将Redis配置为使用AuthorID作为Author_Book实体的Key字段。
试图获取Author.Id = 2

问题是，它只给我Book-3，预期结果为Book-2和Book-3。

我猜rc.Store<Author_Book>(ab3);正在覆盖之前的记录，因为ab2和ab3都有相同的作者ID。

如何实现它？

我想存储单独的实体列表而不是Graph，以便稍后可以单独更新/删除它们。

ServiceStack.Redis使用实体属性而不是ID搜索列表
