Auto.Core (基于AspectCore)

介绍

Auto.Core是基于 .Net Standard 2.1用于简化 ASP.NET Core开发，Auto.Core 在 AspectCore 的基础上进行功能开发，AspectCore 在性能上都比反射有2个数量级的优化，达到了和硬编码调用相同的数量级。

AspectCore 方法调用反射扩展

性能测试:（Reflection为.NET Core提供的反射调用，Reflector为AspectCore.Extension.Reflection调用，Native为硬编码调用

 |             Method |        Mean |     Error |    StdDev |    StdErr |            Op/s |
 |------------------- |------------:|----------:|----------:|----------:|----------------:|
 |        Native_Call |   1.0473 ns | 0.0064 ns | 0.0050 ns | 0.0015 ns |   954,874,046.8 |
 |    Reflection_Call |  91.9543 ns | 0.3540 ns | 0.3311 ns | 0.0855 ns |    10,874,961.4 |
 |     Reflector_Call |   7.1544 ns | 0.0628 ns | 0.0587 ns | 0.0152 ns |   139,774,408.3 |

快速开始

1. 安装

• Package Manager

Install-Package Auto.Core

• .NET CLI

dotnet add package Auto.Core

2. 配置 ServiceProviderFactory

builder.Host.UseServiceProviderFactory(new AutoServiceProviderFactory());

3. 注册AutoCore

builder.Services.AddAutoCore(builder.Configuration);

4. AutoOptions (选项)

//appsettings.json
{
  "Redis": {
    "Host": "localhost",
    "Port": 6379,
    "Password": "zxc123..."
  }
}

//选项类：标记绑定
[AutoOptions(Node ="Redis")]
public class Redis
{
    public string Host { get; set; }
    public int Port { get; set; }
    public string Password { get; set; }
}

//构造函数注入
private readonly Redis _redis;
public WeatherForecast(IOptionsSnapshot<Redis> options)
{
     _redis = options.Value;
}

5. AutoCache (缓存)

//方法：标记缓存
[AutoCache]
public virtual async Task<IEnumerable<WeatherForecast>> Get(User user)
{
    var ss = Enumerable.Range(1, 5).Select(index => new WeatherForecast
    {
        Date = DateTime.Now.AddDays(index),
        TemperatureC = Random.Shared.Next(-20, 55),
        Summary = Summaries[Random.Shared.Next(Summaries.Length)]
    }).ToArray();

    return ss;
}

6. AutoService(服务注册)

//接口
public interface IUser
{
    void Get();
}

//实现：标记注册
[AutoService]
public class User : IUser
{
    public void Get()
    {
        Console.WriteLine(1);
    }
}

//构造函数注入
private readonly IUser _user;
public WeatherForecastController(IUser user)
{
    _user = user;
}

7. 参数校验

//参数校验：参数标记校验方法
public WeatherForecast([NotNull] string userName)
{
  string  un = userName;
}

AutoCache（缓存）

1. redis缓存提供

Install-Package Auto.Core.Redis

2. 注册

builder.Services.AddAutoRedis();

3. appsettings.json

{
  "RedisOptions": {
    "Host": "127.0.0.1",
    "Port": 6379,
    "Database": 0
  }
}

AutoValidation（参数校验）

1. 字符串最大长度 [MaxLengthAttribute]

2. 字符串最小长度 [MinLengthAttribute]

3. 字符串不能为空或Null [NotNullOrEmptyAttribute]

4. 字符串不能为Null或空格 [NotNullOrWhiteSpaceAttribute]

5. 对象不能为Null [NotNullAttribute]

6. 范围 [RangeAttribute]

常见问题

功能无法正常使用

1. 检查方法设置为 virtual

[HttpPost(Name = "GetWeatherForecast")]
[AutoCache]
public virtual async Task<IEnumerable<WeatherForecast>> Get(User user)
{
    var ss = Enumerable.Range(1, 5).Select(index => new WeatherForecast
    {
                    Date = DateTime.Now.AddDays(index),
                    TemperatureC = Random.Shared.Next(-20, 55),
                    Summary = Summaries[Random.Shared.Next(Summaries.Length)]
        }).ToArray();

       return ss;
    }
}

注意：控制器中的方法需要注册为服务后才可以使用

builder.Services.AddControllers().AddControllersAsServices();

2. 检查是否注册AutoCore

builder.Services.AddAutoCore(builder.Configuration);

3. 检查是否配置ServiceProviderFactory

builder.Host.UseServiceProviderFactory(new AutoServiceProviderFactory());
