????? 完全通過配置實現(xiàn)AOP的資料太少了，今天忙了好幾個小時終于走通了，分享一下。

????? 模擬業(yè)務(wù)是：登陸，記錄登陸日志。

??????

// 業(yè)務(wù)接口 public interface IStudentManage{bool Login(string userId, string userName);}public class StudentManage:IStudentManage{public StudentManage() { }public bool Login(string userId, string userName){return userId == "123" && userName == "123";}}/// <summary>/// 登陸日志/// </summary>public class UserLogCallHandler : ICallHandler{/// <summary>/// 構(gòu)造函數(shù)，此構(gòu)造函數(shù)是用于Attribute調(diào)用 /// </summary>/// <param name="message"> 消息 </param>/// <param name="parameterName"> 參數(shù)名 </param>public UserLogCallHandler(string message, string parameterName){this.Message = message;this.ParameterName = parameterName;}public IMethodReturn Invoke(IMethodInvocation input, GetNextHandlerDelegate getNext){//檢查參數(shù)是否存在if (input == null) throw new ArgumentNullException("input");if (getNext == null) throw new ArgumentNullException("getNext");//開始攔截，此處可以根據(jù)需求編寫具體業(yè)務(wù)邏輯代碼//調(diào)用具體方法var result = getNext()(input, getNext);// 記錄登陸日志}public string Message { get; set; }public string ParameterName { get; set; }private int order = 0;public int Order{get{return order;}set{order = value;}}}

　　最關(guān)鍵的XML配置

?

<configuration><configSections><section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration"/></configSections><unity xmlns="http://schemas.microsoft.com/practices/2010/unity"><assembly name="UnityAOPConfig"/><namespace name="UnityAOPConfig"/><!--新增配置節(jié)擴(kuò)展，用于下面的<interception>配置節(jié)--><sectionExtension type="Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension,Microsoft.Practices.Unity.Interception.Configuration" /><container name="LoginContainer"><!--為容器增加Interception擴(kuò)展，如不增加下面interception配置會報錯--><extension type="Interception"/><interception><!--增加一個名為UserLog的攔截策略，用于記錄日志--><policy name="UserLog"><!--新增MemberNameMatchingRule匹配規(guī)則，同時需要同過配置初始化匹配規(guī)則構(gòu)造函數(shù)具體可查看Unity.InterceptionExtension.PolicyInjection.MatchRule下具體類--><matchingRule name="rule1" type="MemberNameMatchingRule"><lifetime type="singleton"/><constructor><param name="nameToMatch" value="Login"/></constructor></matchingRule><!--增加調(diào)用處理程序，這邊指定的是我自定義的UserLogCallHandler--><!--同樣也需要初始化構(gòu)造函數(shù)--><callHandler name="handler1"type="UserLogCallHandler"><lifetime type="singleton"/><constructor><param name="message" type="System.String" value="登錄成功！"></param><param name="parameterName" type="System.String" value=" "></param></constructor></callHandler></policy></interception><!--注冊對象關(guān)系，需要注意的是需要為這個注冊增加TransparentProxyInterceptor的攔截器--><register type="IStudentManage" mapTo="StudentManage"><interceptor type="TransparentProxyInterceptor" /><interceptionBehavior type="PolicyInjectionBehavior" /></register></container></unity> </configuration>

　　前臺調(diào)用代碼

public static IUnityContainer GetIUnityContainer(string nodeName){//根據(jù)文件名獲取指定config文件var fileMap = new ExeConfigurationFileMap { ExeConfigFilename = "Web.config" };//從config文件中讀取配置信息Configuration configuration =ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);var unitySection = (UnityConfigurationSection)configuration.GetSection("unity");var container = new UnityContainer().LoadConfiguration(unitySection, nodeName);return container;}protected void btnSubmit_Click(object sender, EventArgs e){IUnityContainer container = new UnityContainer().LoadConfiguration("LoginContainer");IStudentManage studentBll = container.Resolve<IStudentManage>();if (studentBll.Login(txtUid.Text.Trim(), txtPwd.Text.Trim())){if (string.IsNullOrEmpty(Request.QueryString["returnUrl"]) == false){Response.Redirect(Request.QueryString["returnUrl"]);}else{Response.Redirect("~/Default.aspx");}}else{ltMsg.Text = "用戶名或密碼不正確,請重試!";}}}
