ASP.NET Core 3.0 缓存(Cache)之 SQL Server 缓存

ASP.NET Core 缓存 Caching 提供了包括但不限于以下几种存储方式:

内存缓存:https://xoyozo.net/Blog/Details/aspnetcore-memory-cache

SQL Server 缓存:https://xoyozo.net/Blog/Details/aspnetcore-sql-cache

Redis 缓存:https://xoyozo.net/Blog/Details/aspnetcore-redis-cache

MySQL 缓存:https://xoyozo.net/Blog/Details/aspnetcore-mysql-cache


Nuget 安装:Microsoft.Extensions.Caching.SqlServer

执行 .NET Core CLI 命令,在数据库中创建表“TestCache”

dotnet sql-cache create "数据库连接字符串" dbo TestCache

若提示

找不到 "dotnet sql-cache" 命令,请运行以下命令进行安装

则运行

dotnet tool install --global dotnet-sql-cache

表和索引创建成功提示:

Table and index were created successfully.

表结构:

在 Startup.cs 文件的方法 ConfigureServices() 中添加:

services.AddDistributedSqlServerCache(options =>
{
    options.ConnectionString = "数据库连接字符串";
    options.SchemaName = "dbo";
    options.TableName = "TestCache";
});

在控制器中注入 IDistributedCache:

public class TestController : Controller
{
    private readonly IDistributedCache cache;

    public TestController(IDistributedCache cache)
    {
        this.cache = cache;
    }

    public IActionResult Index()
    {
        string k = "count";
        int v = Convert.ToInt32(cache.GetString(k));
        v++;
        cache.SetString(k, v.ToString());
        return Content(v.ToString());
    }
}

结果:
