日志

LCL日志提供了一个公共接口，如果需要的话，可以很容易的更改它

使用日志 示例：

        Logger.LogInfo("就一行是不是很简单 ");
        

默认实现的日志接口：

• file
• system event
• trace

自定义日志：

实现自己的日志需要继承LoggerBase类 如下示例：

    public class FileLogger : LoggerBase
    {
      
        public override void LogInfo(string message)
        {
            string msg = string.Format(@"{0}|{1}|Inform|{2}" + Environment.NewLine, DateTime.Now, 
Thread.CurrentThread.ManagedThreadId, message);
            AppendAllText(msg);
        }
      
        public override void LogWarn(string message)
        {
            string msg = string.Format(@"{0}|{1}|Warn|{2}" + Environment.NewLine, DateTime.Now, 
Thread.CurrentThread.ManagedThreadId, message);
            AppendAllText(msg, LogType.Warn);
        }
     
        public override void LogDebug(string message)
        {
            string msg = string.Format(@"{0}|{1}|Debug|{2}" + Environment.NewLine, DateTime.Now, 
Thread.CurrentThread.ManagedThreadId, message);
            AppendAllText(msg, LogType.Debug);
        }
        public override void LogError(string title, Exception e)
        {
            var stackTrace = e.StackTrace;
            e = e.GetBaseException();
            string msg = string.Format(@"{0}|{1}|Error|{2}" + Environment.NewLine, DateTime.Now, 
Thread.CurrentThread.ManagedThreadId, title + e.ToString());
            AppendAllText(msg, LogType.Error);
        }
        public override void LogDbAccessed(string sql, IDbDataParameter[] parameters, 
DbConnectionSchema connectionSchema)
        {
            var content = sql;
            if (parameters.Length > 0)
            {
                var pValues = parameters.Select(p =>
                {
                    var value = p.Value;
                    if (value is string)
                    {
                        value = '"' + value.ToString() + '"';
                    }
                    return value;
                });
                content += Environment.NewLine + "Parameters:" + string.Join(",", pValues);
            }
            content = DateTime.Now + Environment.NewLine + "Database:  " + connectionSchema.Database +
 Environment.NewLine + content + "\r\n\r\n\r\n";
            AppendAllText(content, LogType.Trace);
        }
        private void AppendAllText(string contents, LogType logType = LogType.Info)
        {
            string path = AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "/" 
+ EngineContext.Current.Resolve《lconfig》().LoggerPath;
            string logfile = path + "/" + logType + DateTime.Now.ToString("yyyyMMdd") + "log.log";
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            File.AppendAllText(logfile, contents);
        }
    }
     

注入自定义的日志：

在项目启动的地方注入自定义日志就可以了，如在Global.asax文件中写入如下代码

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        Logger.SetImplementation(new FileLogger());
    }
}
