一. 写在前面
日志系统对于任何项目都是必不可少的,无论对于测试阶段的debug,性能测试,执行时间,操作记录还是线上的问题排查,访问记录等,日志系统都扮演着重要的角色。本篇分享的目的是能帮助需要的人快速搭建自己的LogSystem.,仅供参考。 先上个图呗,自认为页面还算清爽吧:
我的LogSystem使用Log4net入库的方式,网上特别多的分享,但是能完整运行下来的真是很少,所以现在需要和以后用得上的小伙伴抓紧收藏咯。
二. Log4Net自定义内容入库
Log4Net存日志的方式,给人的感觉实在是不实用,IT行业不都求一个自动化吗?废话不说了,先上Log4net入库系统的代码。
LogSystem数据库结构,我的建议是一个项目一个表。
在Log组件中,你需要这样几个类。下面分别给出代码:
LogContent.cs,这里定义了Log实体,在实体化实体的时候,通过给构造函数传参创建好这个对象。注释很详细了

LogHelper.cs,定义了日志级别,和写入方法

其实看到这里,最重要的并不是代码了,核心部分Log4net都帮我们写好了,关键在于你的配置,下面是log4net.config的内容。拿到你的web项目里是一样用的。但是不要忘了在你的项目中引用nuget:log4net哟。
log4net.config如下:在其中主要配置了log入库的参数和sql语句,当然还有sql连接。注释已经很详细了

这样一来,你的配置就完成了,你可以直接测试插入的情况:
三. 把Log信息可视化
我的UI使用的是Datatables.js,弹出框是layer,日期组件好像是layDate,下拉框是修改样式后的select2。UI代码是我自己的一个框架里的,内容太多就不贴出来了,你只需要和以前一样,把数据从库里查出来,绑定给任意你喜欢的数据表格上。由于单页面的日志系统没有什么复杂操作,就用个sqlHelper查一下就算了,代码和条件拼接如下
