日常工作中免不了用缓存，总不能在每个代码块加上缓存

我用Qjx.CustomCache 中间件，进行AOP拦截，统一设置API缓存

步骤如下

（1）引入nuget:Qjx.CustomCache

(2)改造Program

  public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                //改用Autofac来实现依赖注入
                .UseServiceProviderFactory(new AutofacServiceProviderFactory())
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                    
                });

（3）改造Startup

  public IConfiguration Configuration { get; }


        //autofac 新增
        public ILifetimeScope AutofacContainer { get; private set; }
  public void ConfigureServices(IServiceCollection services)
        {
            //支持redis
           services.AddRedisCacheSetup(o=> { o.Configuration = "localhost"; });
            //支持本地缓存
             //services.AddMemoryCacheSetup();
//other code
｝
  public void ConfigureContainer(ContainerBuilder builder)
        {

            builder.RegisterType<CacheAOP>();
            var assembly = this.GetType().GetTypeInfo().Assembly;
            builder.RegisterAssemblyTypes(assembly).EnableClassInterceptors();
      }

(4)改造API 在需要AOP拦截的类上加上

[Intercept(typeof(CacheAOP))]

[Intercept(typeof(CacheAOP))]
    [ApiController]
    [Route("[controller]")]

    public class WeatherForecastController : ControllerBase

（5）改造方法

在需要缓存的地方加上如下缓存单位S

[Caching(AbsoluteExpiration = 1000, KeyName = "id-{#id}", Method = CacheMethod.Add)
           ]

  [Route("adddata1")]
        [HttpGet]
        [Caching(AbsoluteExpiration = 1000, KeyName = "id-{#id}", Method = CacheMethod.Add)
           ]
        public virtual  Xuliehua adddata1([FromQuery] Myid myid)
        {
            Debug.WriteLine("this is getnme");
            Xuliehua hua = new Xuliehua();
            hua.obj = DateTime.Now.ToString();
            return hua;
        }
