#BSF.Aop# .Net 免费开源,静态Aop织入(直接修改IL中间语言)框架,类似PostSharp(收费);
实现前后Aop切面和INotifyPropertyChanged注入方式。

描述:

  • 静态织入实现,性能几乎接近原生代码编写。
  • 项目结构扩展自BSF基础架构,但dll方面并不依赖BSF.dll,可以独立开发使用。
  • 项目代码量少(也就几个类文件),核心功能插件化开发,便于第三方扩展,阅读,调试,一起来完善。
  • .net Aop静态织入相关的免费开源项目比较少或暂未听闻,故希望开源这块内容,成为同类型开源项目的起点和借鉴。

这个aop 属于研究性质的,暂时没有在正式项目中使用(在开源反馈上来说大的项目似乎有环境问题)。如果是学习话,建议看下代码。如果是项目中正式用,暂不建议。

使用配置

1)项目引用BSF.Aop.dll,引用Mono.Cecil.dll,引用Mono.Cecil.Pdb.dll。
2)项目启动代码添加AopStartLoader.Start();一句代码即可。
(该代码用于自动注入扫描和vs项目环境自动配置,导出相关exe文件等)

备注:

  • Web项目在Application_Start中添加
  • Winform项目在Pragram.Main中添加

自动化配置(默认推荐)

Build项目,然后直接运行调试项目。

备注:

  • AopStartLoader.Start();这句代码第一次项目运行会报错,因为Aop环境未曾自动搭建;第一次运行并自动搭建成功后,以后运行都是自动注入的。
  • 默认会在项目下生成“packages.BSF.Aop”文件夹,并在vs项目PostBuildEvent事件中注入“aop运行脚本”,具体参考以下“手工配置内容”。

手工配置 (遇到问题,推荐使用)

1)配置Aop注入目录。
vs项目下新建packages.BSF.Aop 目录,里面分别包含BSF.Aop.ILRun.exe,BSF.Aop.dll,Mono.Cecil.Pdb.dll,Mono.Cecil.dll 这几个文件。
2)配置PostBuildEvent 脚本。

winform环境:

打开vs-》项目属性-》PostBuildEvent,配置aop运行脚本。如:
xcopy $(OutDir)BSF.Aop.dll $(ProjectDir)packages.BSF.Aop\ /Y
call "$(ProjectDir)packages.BSF.Aop\BSF.Aop.ILRun.exe" msgbox $(TargetDir)

web环境:

打开vs-》项目属性-》PostBuildEvent,配置aop运行脚本。(OpenApi.Test.Web替换成具体的项目名) 如:
xcopy $(SolutionDir)\OpenApi.Test.Web\bin\BSF.Aop.dll $(SolutionDir)\OpenApi.Test.Web\packages.BSF.Aop\ /Y
call "$(SolutionDir)\OpenApi.Test.Web\packages.BSF.Aop\BSF.Aop.ILRun.exe" msgbox $(SolutionDir)\OpenApi.Test.Web\bin<br/>

使用demo示例

  1. 前后Aop切面示例 (详细参考BSF.Aop.Test项目
public class AroundAopTest
    {
        [MyAroundAop]
        [AttributeInfo(Des = "测试2")]
        public void Method(TempInfo info, out int b,int a=1)
        {
            a = 222;
            b = 3;
            System.Console.WriteLine("Hello world!"+a);
        }
    }

    public static class AroundAopTest2
    {
        [MyAroundAop][AttributeInfo(Des ="测试")]
        public static void Method2(TempInfo info, int a = 1)
        {
            a = 222;
            System.Console.WriteLine("Hello world!" + a);

        }
    }

    public class MyAroundAop : Aop.Attributes.Around.AroundAopAttribute
    {
        public MyAroundAop()
        {
        }


        public override void Before(AroundInfo info)
        {
            var att = info.Method.CustomAttributes.ToList()[0];
            info.Params["a"] = 55;
            System.Console.WriteLine("before" + info.Params["a"]);
        }

        public override void After(AroundInfo info)
        {
            System.Console.WriteLine("after"+ info.Params["a"]);
        }
    }

    public class TempInfo
    {
        public int T1 { get; set; }
    }

    public class AttributeInfo : System.Attribute
    {
        public string Des { get; set; }
    }
  1. INotifyPropertyChanged 示例(暂未测试真正使用效果,详细参考BSF.Aop.Test项目

 [NotifyPropertyChangedAop]
    public class User
    {
        public string Name { get; set; }

        public int Age { get; set; }

        [NoAop]
        public int B { get; set; }
    }
