我在aspnetcore boilerpalte项目中工作。我想使用log4net将日志保存在数据库中。这些是我的app.config文件设置如下。
<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="ADONetAppender" />
</root>
<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="server=.; Database=RBCSDb; User Id=sa; Password=sigma; Integrated Security=false" />
<commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
<parameter>
<parameterName value="@log_date"/>
<dbType value="DateTime"/>
<layout type="log4net.Layout.RawTimeStampLayout"/>
</parameter>
<parameter>
<parameterName value="@thread"/>
<dbType value="String"/>
<size value="255"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%thread"/>
</layout>
</parameter>
<parameter>
<parameterName value="@log_level"/>
<dbType value="String"/>
<size value="50"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level"/>
</layout>
</parameter>
<parameter>
<parameterName value="@logger"/>
<dbType value="String"/>
<size value="255"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%logger"/>
</layout>
</parameter>
<parameter>
<parameterName value="@message"/>
<dbType value="String"/>
<size value="4000"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message"/>
</layout>
</parameter>
<parameter>
<parameterName value="@exception"/>
<dbType value="String"/>
<size value="2000"/>
<layout type="log4net.Layout.ExceptionLayout"/>
</parameter>
</appender>
我使用codefirst创建了具有相同参数的Log表。我的控制器代码是这样的。
Controller class level:
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
Method Level:
log.Debug("log Debug");
log.Info("log Info");
log.Warn("log Warn");
log.Error("log Error");
log.Fatal("log Fatal");
执行代码后没有在数据库日志表中插入记录。我不知道我哪里错了。任何解决方案?
答案 0 :(得分:1)
为什么不使用ILogger?
using Castle.Core.Logging; //1: Import Logging namespace
public class TaskAppService : ITaskAppService
{
//2: Getting a logger using property injection
public ILogger Logger { get; set; }
public TaskAppService()
{
//3: Do not write logs if no Logger supplied.
Logger = NullLogger.Instance;
}
public void CreateTask(CreateTaskInput input)
{
//4: Write logs
Logger.Info("Creating a new task with description: " + input.Description);
//TODO: save task to database...
}
}
