log4net按照不同的级别输出到不同文件

 

配置目标：

1）一个文件记录全部级别的日志；

2）记录某一级别的日志（使用LevelRangeFilter进行级别的过滤）。

 

Eg：

1. <log4net>
2.   <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
3.     <layout type="log4net.Layout.PatternLayout">
4.       <conversionPattern value="%d [%t] %-5p %l - %m%n %property{ServiceType}"/>
5.     </layout>
6.   </appender>
7.   <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
8.     <layout type="log4net.Layout.PatternLayout">
9.       <conversionPattern value="%d [%t] %-5p %l - %m%n"/>
10.     </layout>
11.   </appender>
12.   <appender name="RollingFileAppenderAll" type="log4net.Appender.RollingFileAppender">
13.     <param name="File" value="Log/alllLog.txt"/>
14.     <appendToFile value="true"/> <rollingStyle value="Composite"/>
15.     <datePattern value="yyyyMM"/>
16.     <maxSizeRollBackups value="100"/>
17.     <maximumFileSize value="2MB"/>
18.  
19.     <PreserveLogFileNameExtension value="true"/>
20.     <staticLogFileName value="false"/>
21.     <layout type="log4net.Layout.PatternLayout">
22.       <param name="ConversionPattern" value="%d %-5p %m%n"/>
23.     </layout>
24.   </appender>
25.  
26.   <appender name="ErrorRollingFileAppender" type="log4net.Appender.RollingFileAppender" LEVEL="ERROR">
27.     <file value="Log/Error.txt" />
28.     <appendToFile value="true" />
29.     <rollingStyle value="Size" />
30.     <maxSizeRollBackups value="10" />
31.     <maximumFileSize value="1024KB" />
32.     <staticLogFileName value="true" />
33.     <layout type="log4net.Layout.PatternLayout">
34.       <conversionPattern value="%date [%thread] %-5level [%logger] [%property{NDC}] - %message%newline" />
35.     </layout>
36.     <filter type="log4net.Filter.LevelRangeFilter">
37.       <param name="LevelMin" value="ERROR" />
38.       <param name="LevelMax" value="ERROR" />
39.     </filter>
40.   </appender>
41.  
42.   <root>
43.     <level value="DEBUG"/>
44.     <appender-ref ref="ConsoleAppender"/>
45.     <appender-ref ref="RollingFileAppenderAll"/>
46.     <appender-ref ref="ErrorRollingFileAppender"/>
47.   </root>
48. </log4net>
