开发任务

• 2019/9/9
• 增加AOP(Aspect Oriented Programming，面向切面编程)
• 例子
• 2019/9/10
• 增加属性注入, 使用反射优化 AspectCore.Extensions.Reflection
• 2019/9/23
• 增加Emit代理AOP（之前的代理是基于DispatchProxy，DispatchProxy不支持构造器注入，才增加的属性注入）
• 例子
• 2019/9/25
• 增加Asp.Net Core 3.0支持，原理参考
• 增加自动注入AOP功能
• 例子
• 2019/9/26
• 增加自定义AOP执行器
• 2019/10/8
• 特性修改, 对After、AfterAsync方法增加了一个处理异常的参数
• 对于IAopActors、DefaultActors的所有参数，增加了一个委托回调的参数
• 修复目标类重名问题
• 例子
• 2019/10/10
• 代理类增加了属性克隆支持
• 增加ValueTask支持
• 增加双版本支持 .Net Standard 2.0.Net Framework 4.5

Code Sample

    //new interface
    public interface ITestClass
    {
        string Hello();
        Task<int> ResultIntAsync();
        Task ReturnAsync();
    }
    
    //new class inherit ITestClass
    [JitInject]
    public class TestClass: ITestClass
    {
        [JitAop]
        public string Hello()
        {
            Console.WriteLine("Hello");
            return "Hello";
        }

        public Task<int> ResultIntAsync()
        {
            Console.WriteLine("ResultIntAsync");
            return Task.FromResult(100);
        }

        public Task ReturnAsync()
        {
            Console.WriteLine("ReturnAsync");
            return Task.CompletedTask;
        }
    }

class TestClass add aop

method "Hello" add default aop, but custom, add attribute inherit JitAopAttribute support async method and sync method

    [AttributeUsage(AttributeTargets.Method)]
    internal class TestJitAttribute : JitAopAttribute
    {
        public override void Before(MethodReflector method, object instance, params object[] param)
        {
            Console.WriteLine($"Before Name:{method.Name}");
        }

        public override void After(MethodReflector method, Exception exception, object instance, params object[] param)
        {
            Console.WriteLine($"After Name:{method.Name}");
        }

        public override Task BeforeAsync(MethodReflector method, object instance, params object[] param)
        {
            Console.WriteLine($"BeforeAsync Name:{method.Name}");
            return Task.CompletedTask;
        }

        public override Task AfterAsync(MethodReflector method, Exception exception, object instance, params object[] param)
        {
            Console.WriteLine($"AfterAsync Name:{method.Name}");
            return Task.CompletedTask;
        }
    }

Edit TestClass

    [JitInject]
    public class TestClass: ITestClass
    {
        [TestJit]
        public string Hello()
        {
            Console.WriteLine("Hello");
            return "Hello";
        }
        
        ///...
    }

cutom Actor

    public class TestActors : IAopActors
    {
        public object Execute(AopContext context)
        {
            throw new NotImplementedException();
        }

        public Task<TResult> ExecuteAsync<TResult>(AopContext context)
        {
            throw new NotImplementedException();
        }

        public Task InvokeAsync(AopContext context)
        {
            throw new NotImplementedException();
        }
    }

Use TestAopActors

    [AopActors(typeof(TestActors))]
    public interface ITestClass
    {
        string Hello();
        Task<int> ResultIntAsync();
        Task ReturnAsync();
    }

Run

Under Asp.net Core 3.0

edit Startup.cs

   public IServiceProvider ConfigureServices(IServiceCollection services)
   {
      //...
      services.AddSingleton<ITestClass, TestClass>();
      return services.BuilderJit();
   }

Asp.net Core 3.0

edit Program.cs

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseServiceProviderFactory(new JitServiceProviderFactory()) //new
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });

edit Startup.cs add Method

        public void ConfigureContainer(JitAopBuilder builder)
        {
            builder.Add<ITestClass, TestClass>(ServiceLifetime.Singleton);
        }
