所以我有一个非常奇怪的问题。我有一个Azure Web作业,我希望在其中添加log4net。
我有以下web.config文件,它与我的Web应用程序具有相同的元素。请注意我的configSections中的log4net声明如何位于顶部:
<?xml version="1.0" encoding="utf-8"?>

<!-- The format of the connection string is "DefaultEndpointsProtocol=https;AccountName=NAME;AccountKey=KEY" -->

但是,当我在仪表板中打开Azure Web作业上的日志时:
Unhandled Exception: System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section log4net. (D:\local\Temp\jobs\continuous\CommunicationSender\13a4pcai.5fk\CommunicationSender.exe.config line 70)
任何人都知道这里发生了什么? :-)我错过了什么?
我在这样的代码中初始化log4net,但我认为由于配置问题,它永远不会被命中:
static void Main()
{
log4net.Config.XmlConfigurator.Configure();
ILog log = log4net.LogManager.GetLogger(typeof(Program));
log.Info("CommunicationSender STARTED! :-)");
var config = new JobHostConfiguration();
if (config.IsDevelopment)
{
config.UseDevelopmentSettings();
}
var host = new JobHost();
// The following code ensures that the WebJob will be running continuously
host.RunAndBlock();
}
答案 0 :(得分:0)
我的一名员工解决了这个问题。他指出configSection需要在ConnectionStrings之前。
切换后,它有效!
