ServiceStack.Redis 之 IRedisTypedClient 04_转

IRedisTypedClient

  IRedisTypedClient类相当于IRedicClient的强类型版,其方法与属性大多数与IRedisClient类似。

  它支持在Redis中使用Linq查询的强大的类,它本身是一个泛型,IRedisClient的泛型方法As获得对象。

  其方法原型如下:

    IRedisTypedClient<T> As<T>();

  1、IEntityStore<T>接口内容

  其中IRedisTypedClient这个类实现了这个接口IEntityStore<T>,该接口要求提供的功能如下:

方法 说明
Delete 根据实体删除一条记录
DeleteAll 全部删除
DeleteById 根据Id删除一条记录
DeleteByIds 根据输入的多个Id删除多条记录
GetAll 获取所有该类型的记录
GetById 根据Id获取一条记录
GetByIds 根据输入的多个Id获取多条记录
Store 根据传入的实体,添加一条记录
StoreAll 根据传入的实体集合,添加多条记录

  Linq查询(针对于GetAll方法返回的IList<T>)示例:

public ActionResult Index()
{
Person p1 = new Person() { Id = , Name = "刘备" };
Person p2 = new Person() { Id = , Name = "关羽" };
Person p3 = new Person() { Id = , Name = "张飞" };
Person p4 = new Person() { Id = , Name = "曹操" };
Person p5 = new Person() { Id = , Name = "典韦" };
Person p6 = new Person() { Id = , Name = "郭嘉" };
List<Person> ListPerson = new List<Person>() { p2,p3,p4,p5,p6 }; using (IRedisClient RClient = prcm.GetClient())
{
IRedisTypedClient<Person> IRPerson = RClient.As<Person>();
IRPerson.DeleteAll(); //------------------------------------------添加-------------------------------------------- //添加单条数据
IRPerson.Store(p1);
//添加多条数据
IRPerson.StoreAll(ListPerson); //------------------------------------------查询-------------------------------------------- //Linq支持
Response.Write(IRPerson.GetAll().Where(m => m.Id == ).First().Name); //刘备
//注意,用IRedisTypedClient的对象IRPerson的Srore()添加的才能用IRPerson()方法读取
Response.Write(IRPerson.GetAll().First(m => m.Id == ).Name); //关羽          //------------------------------------------删除-------------------------------------------- IRPerson.Delete(p1); //删除 刘备
Response.Write(IRPerson.GetAll().Count()); //
IRPerson.DeleteById(); //删除 关羽
Response.Write(IRPerson.GetAll().Count()); //
IRPerson.DeleteByIds(new List<int> { , }); //删除张飞 曹操
Response.Write(IRPerson.GetAll().Count()); //
IRPerson.DeleteAll(); //全部删除
Response.Write(IRPerson.GetAll().Count()); //
} return Content("");
}

另外,由于该接口并没有实现修改的方法,所以修改还得通过IRedisClient的实例:

public ActionResult Index()
{
PooledRedisClientManager prcm = new PooledRedisClientManager(new List<string>() { "127.0.0.1" }, new List<string>() { "127.0.0.1" }, RedisConfig); Person p1 = new Person() { Id = , Name = "刘备" };
Person p2 = new Person() { Id = , Name = "关羽" };
Person p3 = new Person() { Id = , Name = "张飞" };
Person p4 = new Person() { Id = , Name = "曹操" };
Person p5 = new Person() { Id = , Name = "典韦" };
Person p6 = new Person() { Id = , Name = "郭嘉" };
List<Person> ListPerson = new List<Person>() { p2,p3,p4,p5,p6 }; using (IRedisClient RClient = prcm.GetClient())
{
IRedisTypedClient<Person> IRPerson = RClient.As<Person>();
IRPerson.StoreAll(ListPerson); //读取所有的Key
List<string> ListKeys = IRPerson.GetAllKeys();
foreach (string key in ListKeys)
{
Response.Write(key + "<br/>");
} //修改的话只能通过Key修改
//urn:person:3
//urn:person:4
//urn:person:5
//ids:Person
//urn:person:1
//urn:person:6
//urn:person:2
Person p7 = new Person() { Id = , Name = "撼地神牛" };
RClient.Set("urn:person:1", p7);
Response.Write(IRPerson.GetAll().First(m => m.Id == ).Name); //输出 撼地神牛
} return Content("");
}
