ServiceStack.Redis 使用教程[转]

环境准备

在Windows上运行Redis服务器作开发和测试是很好的,但是在运营环境还是Linux版本靠谱,下面我们就先解压Redis到一个目录下:

运行redis-server.exe 看到如下Windows控制台:

image

上面我们可以看到Redis运行的端口是6372

我们先玩一下Redis的客户端控制台,在相同目录下运行redis-cli.exe会弹出另一个控制台程序,可以参考Try Redis tutorial开始你的交互之旅。

输入命令 set car.make “Ford” 添加了一个car.make为Key,Value是Ford的数据进入Redis,输入命令get car.make就可以取回Ford

下面我们进入正题,讲主角ServiceStack.Redis :

首先创建一个控制台程序,然后解压缩ServiceStack.Redis-v3.00.zip ,然后添加下面的四个引用

  • ServiceStack.Common
  • ServiceStack.Interfaces
  • ServiceStack.Redis
  • ServiceStack.Text

我们下面来写些代码,创建一个Car类并存储几个实例到Redis,然后让一个对象5秒后过期,等待6秒钟后输出Car的实例数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ServiceStack.Redis;
using System.Threading;

namespace RedisTutorial
{
class Program
{
static void Main(string[] args)
{
var redisClient = new RedisClient(“localhost”);

using (var cars = redisClient.GetTypedClient<Car>())
{
if (cars.GetAll().Count > 0)
cars.DeleteAll();

var dansFord = new Car
{
Id = cars.GetNextSequence(),
Title = “Dan’s Ford”,
Make = new Make { Name = “Ford” },
Model = new Model { Name = “Fiesta” }
};
var beccisFord = new Car
{
Id = cars.GetNextSequence(),
Title = “Becci’s Ford”,
Make = new Make { Name = “Ford” },
Model = new Model { Name = “Focus” }
};
var vauxhallAstra = new Car
{
Id = cars.GetNextSequence(),
Title = “Dans Vauxhall Astra”,
Make = new Make { Name = “Vauxhall” },
Model = new Model { Name = “Asta” }
};
var vauxhallNova = new Car
{
Id = cars.GetNextSequence(),
Title = “Dans Vauxhall Nova”,
Make = new Make { Name = “Vauxhall” },
Model = new Model { Name = “Nova” }
};

var carsToStore = new List<Car> { dansFord, beccisFord, vauxhallAstra, vauxhallNova };
cars.StoreAll(carsToStore);

Console.WriteLine(“Redis Has-> ” + cars.GetAll().Count + ” cars”);

cars.ExpireAt(vauxhallAstra.Id, DateTime.Now.AddSeconds(5)); //Expire Vauxhall Astra in 5 seconds

Thread.Sleep(6000); //Wait 6 seconds to prove we can expire our old Astra

Console.WriteLine(“Redis Has-> ” + cars.GetAll().Count + ” cars”);

//Get Cars out of Redis
var carsFromRedis = cars.GetAll().Where(car => car.Make.Name == “Ford”);

foreach (var car in carsFromRedis)
{
Console.WriteLine(“Redis Has a ->” + car.Title);
}

}
Console.ReadLine();
}
}

public class Car
{
public long Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public Make Make { get; set; }
public Model Model { get; set; }
}

public class Make
{
public int Id { get; set; }
public string Name { get; set; }
}

public class Model
{
public int Id { get; set; }
public Make Make { get; set; }
public string Name { get; set; }
}

}
