各位
我正在尝试使用 LogCallHandler 进行拦截，如下所示:
<interception>
<policy name="policyLogCallHandler">
<matchingRule name="LogsMachingRule" type="NamespaceMatchingRule">
<constructor>
<param name="namespaceName" value="NetTcpContracts" />
</constructor>
</matchingRule>
<callHandler type="Microsoft.Practices.EnterpriseLibrary.Logging.PolicyInjection.LogCallHandler, Microsoft.Practices.EnterpriseLibrary.PolicyInjection, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="callHandlerLog">
<constructor>
<param name="eventId" value="9002"/>
<param name="logBeforeCall" value="true"/>
<param name="logAfterCall" value="true"/>
<param name="beforeMessage" value="--- begin"/>
<param name="afterMessage" value="--- end"/>
<param name="includeParameters" value="true"/>
<param name="includeCallStack" value="true"/>
<param name="includeCallTime" value="true"/>
<param name="priority" value="1"/>
<param name="order" value="1"/>
</constructor>
</callHandler>
</policy>
</interception>
此配置抛出异常:“尚未为 Logger 静态类设置 LogWriter。请通过调用 Logger.SetLogWriter 方法来设置它。”
我使用运行时配置找到了此问题的解决方案:
IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
Logger.SetLogWriter(logWriterFactory.Create());
LogEntry entry = new LogEntry();
entry.Message = "I am logging";
Logger.Write(entry)
但是，我正在通过配置文件使用配置。如何在配置文件中重现此行为？
谢谢!
最佳答案
企业库的提升行为在版本 6 中已更改。对静态 Logger 外观的影响是您需要设置内部 LogWriter(例如在应用程序启动时): 更多详情请参阅https://entlib.codeplex.com/discussions/442089

关于logging - 企业库6 LogCallHandler抛出异常 "The LogWriter has not been set for the Logger static class"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22558745/
