之前的讲过两篇关于日志组件的文章，分别是《第一回 日志记录组件之自主的Vlog》和《第三回 日志记录组件之log4net》，而今天主要说一下我自己开发的另一种日志组件Logger.Core，它也属于面试ＡＯＰ（横切关注点）的一部分，这个组件对于一些想学习设计模式的同学来说，无疑是一个大餐！Logger.Core项目里内含了策略模式，模版方法模式，工厂模式和单例模式，可以说，最常用的模式都用到了，而它们在这个项目里都起到了什么作用，什么时候用到它们呢，这些答案相信在看完我的文章之后，您会有一个明确的答案的。
一 面向接口编程与多态
面向接口编程，是实现软件解耦的灵魂，也是实现多态的方法之一，日志项目有统一的接口规范
/// <summary>
/// 日志功能接口规范
/// </summary>
public interface ILogger
{
/// <summary>
/// 记录代码运行时间
/// </summary>
/// <param name="message">消息</param>
/// <param name="action">所测试的代码块</param>
/// <param name="fileName">日志文件名</param>
void Logger_Timer(string message, Action action, string fileName); /// <summary>
/// 记录代码运行时间，日志文件名以codeTime开头的时间戳
/// </summary>
/// <param name="message">消息</param>
/// <param name="action">所测试的代码块</param>
void Logger_Timer(string message, Action action); /// <summary>
/// 记录代码运行异常
/// </summary>
/// <param name="message">消息</param>
/// <param name="action">要添加try...catch的代码块</param>
/// <param name="fileName">日志文件名</param>
void Logger_Exception(string message, Action action, string fileName); /// <summary>
/// 记录代码运行异常，日志文件名以Exception开头的时间戳
/// </summary>
/// <param name="message">消息</param>
/// <param name="action">要添加try...catch的代码块</param>
void Logger_Exception(string message, Action action); /// <summary>
/// 将message记录到日志文件
/// </summary>
/// <param name="message"></param>
void Logger_Info(string message); /// <summary>
/// 将message记录到名为fileName的日志文件
/// </summary>
/// <param name="message"></param>
/// <param name="fileName"></param>
void Logger_Info(string message, string fileName);
}
二 继承与面向对象
继承是面向对象的三大特性之一，有了它，面向对象才有了层次感，将公共的功能点从各个派生类抽出，提取到基类中
/// <summary>
/// 日志核心基类
/// 模版方法模式，对InputLogger开放，对其它日志逻辑隐藏，InputLogger可以有多种实现
/// </summary>
internal abstract class LoggerBase : ILogger
{
private string _defaultLoggerName = DateTime.Now.ToString("yyyyMMddhh") + ".log"; /// <summary>
/// 日志文件地址
/// 优化级为mvc方案地址，网站方案地址，console程序地址
/// </summary>
protected string FileUrl
{
get
{
try
{ return System.Web.HttpContext.Current.Server.MapPath("/Logger/"
+ System.Web.HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()
+ "/"
+ System.Web.HttpContext.Current.Request.RequestContext.RouteData.Values["action"].ToString()
+ "/"); //例如：c:\\project\\Logger\\Home\\Index\\
}
catch (NullReferenceException)
{
try
{
return System.Web.HttpRuntime.AppDomainAppPath + "LoggerDir\\"; //例如：c:\\project\\
}
catch (ArgumentNullException)
{ return Environment.CurrentDirectory + "\\LoggerDir\\"; //例如：c:\\project\\bin\\debug
} }
}
} protected abstract void InputLogger(string message, string fileName); #region ILogger 成员 public void Logger_Timer(string message, Action action, string fileName)
{
StringBuilder str = new StringBuilder();
Stopwatch sw = new Stopwatch();
sw.Restart();
str.Append(message);
action();
str.Append("代码段运行时间:" + sw.ElapsedMilliseconds + "毫秒");
InputLogger(str.ToString(), string.IsNullOrWhiteSpace(fileName)
? "CodeTime" + _defaultLoggerName
: fileName);
sw.Stop();
} public void Logger_Timer(string message, Action action)
{
Logger_Timer(message, action, null);
} public void Logger_Exception(string message, Action action, string fileName)
{
try
{
action();
}
catch (Exception ex)
{
InputLogger("代码段出现异常,信息为" + ex.Message, string.IsNullOrWhiteSpace(fileName)
? "Exception" + _defaultLoggerName
: fileName);
}
} public void Logger_Exception(string message, Action action)
{
Logger_Exception(message, action, null);
} public void Logger_Info(string message)
{
InputLogger(message, null);
} public void Logger_Info(string message, string fileName)
{
InputLogger(message, string.IsNullOrWhiteSpace(fileName)
? "Logger" + _defaultLoggerName
: fileName);
} #endregion
}
三 模版方式模式规定具体流程，抽象个性化方法
对于个性化的操作声明为抽象方法，在基类中实现统一的操作流程，在各个派生类中去实现个性化的模块，这正是模版方式模式的体现

四 策略模式以多种方式实现某个功能
对于文件持久化的方式有很多，而你可以分别去实现它，不知不觉中，我们正在使用策略模式来开发应用程序
普通持久化
/// <summary>
/// 以普通的文字流的方式写日志
/// </summary>
internal class NormalLogger : LoggerBase
{
protected override void InputLogger(string message, string fileName)
{
string filePath = FileUrl + (fileName ?? "logger.log");
string dir = filePath.Substring(, filePath.LastIndexOf("\\"));
if (!System.IO.Directory.Exists(dir))
{
System.IO.Directory.CreateDirectory(dir);
}
using (System.IO.StreamWriter srFile = new System.IO.StreamWriter(filePath, true))
{
srFile.WriteLine(message);
srFile.Close();
srFile.Dispose();
}
}
}
log4net实现日志分级的持久化
/// <summary>
/// Function:以log4net组件的方式写日志
/// Remark:日志记录方法可以使用第三方组件,如log4net
/// Author:zhangzhanling
/// Blogs:www.cnblogs.com/lori
/// </summary>
internal class Log4Logger : LoggerBase
{
/// <summary>
/// log4net配置文件路径
/// </summary>
static string _logConfig = System.Web.HttpContext.Current.Server.MapPath("/log4net.config"); static Log4Logger()
{
log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(_logConfig));
} #region Prviate Methods
/// <summary>
/// 写日志方法
/// </summary>
/// <param name="message"></param>
/// <param name="fileName"></param>
protected override void InputLogger(string message, string fileName)
{
string filePath = FileUrl + fileName;
var iLog = log4net.LogManager.GetLogger("Core.Logger");
ChangeLog4netLogFileName(iLog, filePath, message);
} private void ChangeLog4netLogFileName(log4net.ILog iLog, string filePath, string message)
{
log4net.Core.LogImpl logImpl = iLog as log4net.Core.LogImpl;
if (logImpl != null)
{
var ac = ((log4net.Repository.Hierarchy.Logger)logImpl.Logger).Appenders;
var rfa = ac[] as log4net.Appender.RollingFileAppender;
if (rfa != null)
{
string dir = filePath.Substring(, filePath.LastIndexOf("\\"));
if (!System.IO.Directory.Exists(dir))
{
System.IO.Directory.CreateDirectory(dir);
}
rfa.File = filePath;
// 更新Writer属性
rfa.Writer = new System.IO.StreamWriter(rfa.File, rfa.AppendToFile, rfa.Encoding);
rfa.Writer.WriteLine(message);
rfa.Writer.Close();
rfa.Writer.Dispose();
rfa.Close(); } }
} #endregion }
五 工厂模式动态生产对象,单例模式保持对象实例的唯一性
当我们以多种方式实现了对日志的持久化后，我们可以通过工厂模式动态的在这些持久化方式之间实现切换，对象实现单例之后，减少了内存开销，使对象的属性成为了全局性属性！
/// <summary>
/// 日志生产类
/// Singleton模式和策略模式和工厂模式
/// </summary>
public class LoggerFactory : ILogger
{
/// <summary>
/// 对外不能创建类的实例
/// </summary>
private LoggerFactory()
{ string loggerType = System.Configuration.ConfigurationManager.AppSettings["LoggerType"] ?? "NormalLogger";
switch (loggerType)
{
case "NormalLogger":
iLogger = new NormalLogger();
break;
case "Log4Logger":
iLogger = new Log4Logger();
break;
default:
throw new ArgumentException("日志方法不正确，目前只支持NormalLogger和Log4Logger");
}
//(ILogger)Assembly.Load("Logger.Core").CreateInstance("Logger.Core." + className.Trim());
} #region Logger有多种实现时,需要使用Singleton模式 private static object lockObj = new object();
private static LoggerFactory instance = null;
private ILogger iLogger = null;
/// <summary>
/// Get singleton instance of IoCFactory
/// </summary>
public static LoggerFactory Instance
{
get
{
if (instance == null)
{
lock (lockObj)
{
if (instance == null)
{
instance = new LoggerFactory();
}
}
}
return instance;
}
} #endregion #region ILogger 成员 public void Logger_Timer(string message, Action action, string fileName)
{
iLogger.Logger_Timer(message, action, fileName);
} public void Logger_Timer(string message, Action action)
{
iLogger.Logger_Timer(message, action);
} public void Logger_Exception(string message, Action action, string fileName)
{
iLogger.Logger_Exception(message, action, fileName);
} public void Logger_Exception(string message, Action action)
{
iLogger.Logger_Exception(message, action);
} public void Logger_Info(string message)
{
iLogger.Logger_Info(message);
} public void Logger_Info(string message, string fileName)
{
iLogger.Logger_Info(message, fileName);
} #endregion
}
最后有一句话送给大家：坚持，其实就是一种胜利！
