Full-Process Analysis of building a project architecture with nhib.pdf + Oracle10g (5)

7. Add log capability for presentation layer project 1. Add the following code in Web. Config: configdivsdivnamelog4nettypelog4net. Config. Log4NetConfigurationdivHandler, log4netconfigdivslog4netrootlevelvalueINFOappender-refrefLogFileAppendera

7. Add log capabilities for the presentation layer project 1. add the following code to Config: configps p name = "log4net" type = "log4net. config. log4NetConfigurationpHandler, log4net "// configps log4net root level value =" INFO "/appender-ref =" LogFileAppender "/

7. Add logging capabilities for presentation layer Projects

1. Add the following code in Web. Config:<Configps> <p name = "log4net" type = "log4net. config. log4NetConfigurationpHandler, log4net "/> </configps> <log4net> <root> <level value =" INFO "/> </root> <param name =" File "value =" log-file.txt "/> <param name = "AppendToFile" value = "false"/> <layout type = "log4net. layout. patternLayout "> <param name =" Header "value =" [Header]/r/n "/> <param name =" Footer "value =" [Footer]/r/n "/> <param name =" ConversionPattern "value =" % d [% t] %-5 p % c [% x]-% m % n "/> </layout> <filter type = "log4net. filter. levelRangeFilter "> <param name =" LevelMin "value =" INFO "/> <param name =" LevelMax "value =" WARN "/> </filter> </appender> <layout type = "log4net. layout. patternLayout "> <param name =" ConversionPattern "value =" % d [% t] %-5 p % c [% x]-% m % n "/> </layout> <filter type = "log4net. filter. levelRangeFilter "> <param name =" LevelMin "value =" DEBUG "/> <param name =" LevelMax "value =" WARN "/> </filter> </appender> </log4net>

2. Add the following code to the AssemblyInfo. cs file of Properties in the persistence layer project OfficeDAL:

[Assembly: log4net. Config. XmlConfigurator (ConfigFile = "Web. Config", Watch = true)]

When you run a web project, the log file log-file.txt will be generated under the project.

3. We can add our own log code in the persistence layer for log output:
