AOP -- Unity

1,使用Unity首先需要在NuGet上面添加关于Unity的相关插件.

1,Unity.Configuration 2,Unity.Abstractions 3,Unity.Container 4,Unity.Interception 5,Unity.Interception.Configuration (特别注意)

1,特别注意在添加unity文件中需要填加unity.json的文件夹文件的配置如下

 1 <configuration>
 2   <configSections>
 3     <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Unity.Configuration"/>
 4     <!--Microsoft.Practices.Unity.Configuration.UnityConfigurationSection-->
 5   </configSections>
 6   <unity>
 7     <sectionExtension type="Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension, Unity.Interception.Configuration"/>
 8     <containers>
 9       <container name="aopContainer">
10         <extension type="Interception"/>  
11         <register type="Aop.UnityWay.IUserProcessor,Aop" mapTo="Aop.UnityWay.UserProcessor,Aop">
12           <interceptor type="InterfaceInterceptor"/>
13           <interceptionBehavior type="Aop.UnityWay.ExceptionLoggingBehavior, Aop"/>
14           <!--<interceptionBehavior type="Aop.UnityWay.MoniterBehavior, Aop"/>
15           <interceptionBehavior type="Aop.UnityWay.LogBeforeBehavior, Aop"/>
16           <interceptionBehavior type="Aop.UnityWay.ParameterCheckBehavior, Aop"/>
17           <interceptionBehavior type="Aop.UnityWay.CachingBehavior, MyAOP"/>-->
18       
19           <!--<interceptionBehavior type="Aop.UnityWay.LogAfterBehavior, Aop"/>--> 
20         </register>
21       </container>
22     </containers>
23   </unity>
24 </configuration>

但是想要使用unity进行AOP的配置的话我们需要配置一些相应的信息

fileMap.ExeConfigFilename:来配置Json文件的地址文件

 1    //配置UnityContainer
 2             IUnityContainer container = new UnityContainer();
 3             ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
 4             fileMap.ExeConfigFilename = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + "CfgFiles\\Unity.Config");
 5             Configuration configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
 6 
 7             UnityConfigurationSection configSection = (UnityConfigurationSection)configuration.GetSection(UnityConfigurationSection.SectionName);
 8             configSection.Configure(container, "aopContainer");
 9 
10             IUserProcessor processor = container.Resolve<IUserProcessor>();
11             processor.RegUser(user);

配置完成之后我们再来解读一下json文件中的相关信息

下面我们来看看程序调用的类应当注意的事项

1, 当前的类必须继承接口IInterceptionBehavior 才能是Aop正常的触发

2, getNext()(input, getNext);执行下一个程序,这里是指aop下的下一个程序

 1   public class ExceptionLoggingBehavior : IInterceptionBehavior
 2     {
 3         public IEnumerable<Type> GetRequiredInterfaces()
 4         {
 5             return Type.EmptyTypes;
 6         }
 7 
 8         public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
 9         {
10             Console.WriteLine("ExceptionLoggingBehavior");
11             IMethodReturn methodReturn = getNext()(input, getNext);
12             if (methodReturn.Exception == null)
13             {
14                 Console.WriteLine("无异常");
15             }
16             else
17             {
18                 Console.WriteLine($"异常:{methodReturn.Exception.Message}");
19             }
20             return methodReturn;
21         }
22 
23         public bool WillExecute
24         {
25             get { return true; }
26         }

2或者使用日常的程序数据校验将数据的内容和值进行关闭

 1   public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
 2         {
 3             Console.WriteLine("ParameterCheckBehavior");
 4             //通过特性校验
 5             User user = input.Inputs[0] as User;
 6             if (user.Password.Length < 10)
 7             {
 8                 //throw new Exception(); 
 9                 return input.CreateExceptionMethodReturn(new Exception("密码长度不能小于10位"));
10             }
11             else
12             {
13                 Console.WriteLine("参数检测无误");
14                 return getNext().Invoke(input, getNext);
15             }
16         }
