.NET CORE 使用log4net 教程

第一步NuGet，在公共类库引用log4net的文件，当然你想在其它类库也可以引用，但建议是在公共类库引用。

第二步在WebApi项目下建立log4net.config 文件，复制以下内容到这个文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout" value="%date [%thread] %-5level %logger - %message%newline" />
</appender>

<root>
<level value="ALL" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="FileAppender" />
<appender-ref ref="RollingLogFileAppender" />
</root>

</log4net>
</configuration>

第三步在Startup 文件下添加如下代码，标红是我添加的

public class Startup
{
public static ILoggerRepository repository { get; set; }
public Startup(IConfiguration configuration)
{
Configuration = configuration;
repository = LogManager.CreateRepository("GD.Core");
//指定配置文件
XmlConfigurator.Configure(repository, new FileInfo("log4net.config"));
}

public IServiceProvider ConfigureServices(IServiceCollection services)
{

//log日志注入
services.AddSingleton<ILogger, LogHelper>();

｝

第四步在Services层添加如下代码

namespace Guet.Services
{
/// <summary>
/// 公告表
/// </summary>
public class SysNoticeServices : BaseServices<SysNotice>, ISysNoticeServices
{

private ISysNoticeRepository dal;
private ISysUserRepository SysUserRepository;
private IMapper Mapper;
private readonly IUnitOfWork UnitOfWork;
private ILogger Logger;
public SysNoticeServices(IUnitOfWork UnitOfWork, ISysNoticeRepository dal, IMapper Mapper, ISysUserRepository SysUserRepository, ILogger Logger)
{
this.dal = dal;
base.baseDal = dal;
this.Mapper = Mapper;
this.UnitOfWork = UnitOfWork;
this.SysUserRepository = SysUserRepository;
this.Logger = Logger;
}

第五步，就可以直接通过Logger.Debug();
