背景
- 项目开发中,我们或多或少会使用诸如NLog,Log4Net,Kafka+ELK等等日志套件;
- 基于关注点分离原则,业务开发的时候不应该关注日志具体实现;并且后续能方便切换其他日志套件;
- 这里先实现基于文件的日志服务,在下一篇将实现基于Kafka+ELK;
- 具体源码:MasterChief
- Nuget:Install-Package MasterChief.DotNet.Core.Log
- 欢迎Star,欢迎Issues;

怎么使用
private IKernel _kernel = null;
private ILogService _logService = null;
[TestInitialize]
public void SetUp()
{
_kernel = new StandardKernel(new LogModule());
Assert.IsNotNull(_kernel);
_logService = _kernel.Get<ILogService>();
}
[TestMethod()]
public void DebugTest()
{
_logService.Debug("DebugTest");
}
结语
- 整个实现很简单,就是业务或者功能不依赖具体实现类,这也是开发中最基本原则;
- 小弟不才,大佬轻拍;
