<div id="8750-1547734396925" style="font-size: 14px; white-space: pre-wrap; line-height: 1.75;"><span style="font-size: 28px; font-weight: bold;">为什么我喜欢打标签来配置AOP
<div style="font-size: 14px; white-space: pre-wrap; line-height: 1.75;">1. 配置多很混乱，代码里面很难分辨出来哪些是AOP容器(比如属性注入)
<div style="font-size: 14px; white-space: pre-wrap; line-height: 1.75;">2. 对于代码生成器生成的代码里面还需要手动加到配置里面
<div style="font-size: 14px; white-space: pre-wrap; line-height: 1.75;">3. 连java spring现在都是清一色的注解来代替xml，这个就是趋势所在
<div style="font-size: 14px; white-space: pre-wrap; line-height: 1.75;">?
<div style="font-size: 14px; white-space: pre-wrap; text-align: left; line-height: 1.25;">我基于<span style="font-size: 17px; color: #24292e; background-color: #ffffff;">Autofac开发了一个基于标签来配置AOP的扩展

 builder = <span style="color: #008000;">//<span style="color: #008000;"> 注册autofac打标签模式

builder.RegisterModule(<span style="color: #0000ff;">new AutofacAnnotationModule(<span style="color: #0000ff;">typeof<span style="color: #000000;">(AnotationTest).Assembly));

<span style="color: #008000;">//<span style="color: #008000;">如果需要开启支持循环注入

<span style="color: #008000;">//<span style="color: #008000;">builder.RegisterModule(new AutofacAnnotationModule(typeof(AnotationTest).Assembly).SetAllowCircularDependencies(true));

<span style="color: #0000ff;">var container =<span style="color: #000000;"> builder.Build();

<span style="color: #0000ff;">var serviceB = container.Resolve();
