使用log4net记录ABP日志

demo地址：ABP.WindowsService

该文章是系列文章基于.NetCore和ABP框架如何让Windows服务执行Quartz定时作业的其中一篇。

参考：https://aspnetboilerplate.com/Pages/Documents/Logging

ABP框架使用的是Castle Windsor的日志工具，Castle Windsor定义了日志接口

ILogger，并提供了Log4Net, NLog, Serilog的实现。

首先，nuget添加Abp.Castle.Log4Net，github地址：Abp.Castle.Log4Net。

然后，添加AppConfigurations，根据环境变量获取log4net.config的绝对路径，模仿appsettings.json的使用方式。代码如下：

using Abp.Extensions;

using System.Collections.Concurrent;

using System.IO;

namespace Demo.MyJob.Configuration

{

    public static class AppLog4NetConfigs

    {

        private static readonly ConcurrentDictionary<string, string> Log4NetConfigCache;

        static AppLog4NetConfigs()

        {

            Log4NetConfigCache = new ConcurrentDictionary<string, string>();

        }

        public static void AddProperty(string key, string value)

        {

            log4net.GlobalContext.Properties[key] = value;

        }

        public static string Get(string path, string environmentName = null)

        {

            var cacheKey = path + "#" + environmentName;

            return Log4NetConfigCache.GetOrAdd(

                cacheKey,

                _ => BuildLog4NetConfig(path, environmentName)

            );

        }

        private static string BuildLog4NetConfig(string path, string environmentName = null)

        {

            var configFile = Path.Combine(path, "log4net.config");

            if (environmentName.IsNullOrWhiteSpace())

            {

                return configFile;

            }

            var tempPath = Path.Combine(path, $"log4net.{environmentName}.config");

            if (File.Exists(tempPath))

            {

                configFile = tempPath;

            }

            return configFile;

        }

    }

}

最后，先在ConfigureAppConfiguration获取绝对路径，

AppLog4NetConfigs.AddProperty("LogsDirectory", hostingEnvironment.ContentRootPath);

LogConfigFile = AppLog4NetConfigs.Get(hostingEnvironment.ContentRootPath, hostingEnvironment.EnvironmentName);

接着添加日志配置

IocManager.IocContainer.AddFacility<LoggingFacility>(

    f => f.UseAbpLog4Net().WithConfig(LogConfigFile)

    );

测试一下

在Execute添加日记记录

LogHelper.Logger.Info(nameof(SayHelloJob));

测试ok。

log4net.config参考
