我的解决方案包含一个Windows服务应用程序项目和一个单元测试项目,如下所示:
我在Windows服务应用项目中设置了log4net,如下所示:
步骤1)我已将对log4net的引用添加到我的Windows服务应用程序项目中。
第2步)我的app.config如下所示:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="log.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="100KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - %message %exception%newline" />
</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="LogFileAppender" />
</root>
</log4net>
</configuration>
步骤3)我已将Program.cs添加到主页:
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace MyAppService
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
log4net.Config.XmlConfigurator.Configure();
第4步)在我正在记录的课程中,我已经添加了这个:
private static ILog logger = LogManager.GetLogger(typeof(Reader));
步骤5)我已经添加了这样的日志记录语句:
logger.Info("Data Read Completed Successfully.");
我在单元测试项目中设置了log4net,如下所示:
步骤1)我已将对log4net的引用添加到我的单元测试项目中。
步骤2)我添加了一个app.config文件,如下所示:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net>
<!-- A1 is set to be a ConsoleAppender -->
<appender name="A1" type="log4net.Appender.FileAppender">
<file value="logfile.txt" />
<appendToFile value="false" />
<!-- A1 uses PatternLayout -->
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-4timestamp [%thread] %-5level %logger %ndc - %message%newline" />
</layout>
</appender>
<!-- Set root logger level to DEBUG and its only appender to A1 -->
<root>
<level value="DEBUG" />
<appender-ref ref="A1" />
</root>
</log4net>
</configuration>
步骤3)我已将ForecastIOTest.cs单元测试类添加到此:
using log4net;
using log4net.Config;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using System.Collections.Generic;
using WeatherAppService;
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace WeatherAppTests
{
[TestClass]
public class ForecastIOTest
{
private static ILog logger = LogManager.GetLogger(typeof(WeatherController));
[AssemblyInitialize]
public static void Configure(TestContext tc)
{
log4net.Config.XmlConfigurator.Configure();
}
第4步:在我正在记录的测试课程中,我添加了这个:
private static ILog logger = LogManager.GetLogger(typeof(ForecastIOTest));
步骤5)我已经添加了这样的日志记录语句:
logger.Info("This is a test.");
现在,我收到的错误表明我有多个configSections元素:一个位于服务应用中,另一个位于测试应用中。
log4net:ERROR Exception while reading ConfigurationSettings. Check your .config file is well formed XML.
System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Only one <configSections> element allowed per config file and if present must be the first child of the root <configuration> element. (C:\Users\pdl\Documents\Visual Studio 2013\Projects\WeatherAppService\WeatherAppTests\bin\Debug\WeatherAppTests.dll.config line 9)
但是,如果我从测试应用中删除了configSections,则会收到以下错误:
log4net:ERROR Exception while reading ConfigurationSettings. Check your .config file is well formed XML.
System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section log4net. (C:\Users\pdl\Documents\Visual Studio 2013\Projects\WeatherAppService\WeatherAppTests\bin\Debug\WeatherAppTests.dll.config line 7)
有没有人知道如何设置log4net,所以我可以运行单元测试,运行服务应用程序并将我的日志文件写入?或者,鉴于我所做的一切,有人可以告诉我什么是不正确或不完整的吗?
答案 0 :(得分:1)
错误是因为,configSection应该是配置文件中1
之后的第一个元素。
<Configuration>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
元素指定配置和处理程序声明,因此它必须是<ConfigSections>
