- 打开VS中“工具”=》“NuGet程序包管理器”=》“管理解决方案的NuGet程序包”菜单
- 在“管理NuGet程序包”窗口中，搜索log4net，并安装
- 有时候，我们在日志中需要记录一些业务数据，如operator等信息，我们新建一个类WebMethodLog，来存放log里面需要用到的信息
public class WebMethodLog ???{ ???????public string operatorNo{get;set;} ???????public string operatorName { get; set; } ???????public string method { get; set; } ???????public string message { get; set; } ???}- 新建WebMethodPatternConvert类
public class WebMethodPatternConvert : PatternLayoutConverter ???{ ???????protected override void Convert(TextWriter writer, LoggingEvent loggingEvent) ???????{ ???????????var webmethod = loggingEvent.MessageObject as WebMethodLog; ???????????if (webmethod == null) return; ???????????writer.Write("\r\n------------------------------------------------------------begin----------------------------------------------------------------------"); ???????????writer.Write("\r\nDate: "+System.DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss,fff")); ???????????writer.Write(string.Format("\r\nOperator No.: {0}, Operator Name: {1}",webmethod.operatorNo,webmethod.operatorName)); ???????????writer.Write(string.Format("\r\nMethod: {0}", webmethod.method)); ???????????writer.Write("\r\nMessage: "+webmethod.message); ???????????writer.Write("\r\n------------------------------------------------------------end-------------------------------------------------------------------------"); ???????} ????}- 新建WebMethodPatternLayout类
public class WebMethodPatternLayout : log4net.Layout.PatternLayout ?????{ ???????public WebMethodPatternLayout() ???????{ ???????????this.AddConverter("webMethod", typeof(WebMethodPatternConvert)); ???????} ???????}- 在web.config中进行如下配置：
1. 在configSections标签中加入如下配置
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
2. 在configuration标签下加入如下配置
<log4net> ???????<root> ???????????<level value="ALL" /> ???????????<appender-ref ref="InfoAppender" /> ???????????<appender-ref ref="ErrorAppender" /> ???????</root> ???????<logger name="logInfo"> ???????????<level value="Info" /> ???????????<appender-ref ref="InfoAppender" /> ???????</logger> ???????<appender name="InfoAppender" type="log4net.Appender.RollingFileAppender,log4net"> ???????????<param name="File" value="Logs/" /> ???????????<param name="AppendToFile" value="true" /> ???????????<param name="MaxFileSize" value="10240" /> ???????????<param name="MaxSizeRollBackups" value="100" /> ???????????<param name="StaticLogFileName" value="false" /> ???????????<param name="RollingStyle" value="Date" /> ???????????<param name="DatePattern" value=""Logs_"yyyyMMddHH"Info.txt"" /> ???????????????????????<!--<layout type="log4net.Layout.PatternLayout,log4net">--> ???????????<layout type="HITTS.Web.Common.WebMethodPatternLayout"> ???????????????<param name="ConversionPattern" value="%webMethod" /> ???????????</layout> ???????????<filter type="log4net.Filter.LevelRangeFilter"> ?????????????????<levelMin value="ALL" /> ?????????????????<levelMax value="INFO" /> ?????????????</filter> ????????</appender> ???????<logger name="logError"> ???????????<level value="Error" /> ???????????<appender-ref ref="ErrorAppender" /> ???????</logger> ???????<appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender,log4net"> ???????????<param name="File" value="Logs/" /> ???????????<param name="AppendToFile" value="true" /> ???????????<param name="MaxFileSize" value="10240" /> ???????????<param name="MaxSizeRollBackups" value="100" /> ???????????<param name="StaticLogFileName" value="false" /> ???????????<param name="RollingStyle" value="Date" /> ???????????<param name="DatePattern" value=""Logs_"yyyyMMddHH"Error.txt"" /> ???????????<layout type="HITTS.Web.Common.WebMethodPatternLayout"> ???????????????<param name="ConversionPattern" value="%webMethod" /> ???????????</layout> ???????????<filter type="log4net.Filter.LevelRangeFilter"> ?????????????????<levelMin value="ERROR" /> ?????????????????<levelMax value="FATAL" /> ?????????????</filter> ?????????</appender> ???????<appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net"> ???????????<layout type="log4net.Layout.PatternLayout,log4net"> ???????????????<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> ???????????</layout> ???????</appender> ???</log4net>
- 在AssemblyInfo.cs文件中增加如下代码：
[assembly:log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]
- 测试Log代码
[WebMethod]
public static string LogTest()
???????{
???????????log4net.ILog log = log4net.LogManager.GetLogger("InfoTest");
???????????string json = "{‘Name‘:‘Cherry‘,‘Age‘:‘27‘}";
???????????log.Info(new WebMethodLog() { operatorNo = employee.EmployeeNo, operatorName = employee.Name, method = HttpContext.Current.Request.Path, message = json });
???????????log.Error(new WebMethodLog() { operatorNo = employee.EmployeeNo, operatorName = employee.Name, method = HttpContext.Current.Request.Path, message = json });
???????????return json;
???????}
- 测试结果如下：
在Logs文件夹下生成了如下文件：
log4net VS2012 日志layout自定义，error日志和info日志分别记录到不同文件中
