Log4net 数据库存储（四）

1.新建一个空的ASP.Net 空项目，然后添加Default.aspx窗体

2.添加配置文件：log4net.config

  1 <?xml version="1.0" encoding="utf-8"?>
  2 <configuration>
  3 
  4     <system.web>
  5       <compilation debug="true" targetFramework="4.0" />
  6     </system.web>
  7 
  8   <configSections>
  9     <!--添加配置节点-->
 10     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
 11   </configSections>
 12 
 13   <log4net>
 14     <!--定义输出到数据库-->
 15     <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
 16       <!--日志缓存写入条数-->
 17       <!--bufferSize表示批处理的日志事件，可以避免每次日志事件都访问数据库,原本是<bufferSize value="100" />一百条才插入-->
 18       <bufferSize value="1" />

 21       <connectionString value="DATABASE=log4netDB;SERVER=DESKTOP-F0T373H\WZH;UID=sa;PWD=18855162320;Connect Timeout=15;" />
 22       <!--日志数据库脚本-->

 35           <conversionPattern value="%thread" />
 36         </layout>
 37       </parameter>
 38       <!--日志类型LogLevel -->

 54         </layout>
 55       </parameter>
 56       <!--自定义UserId -->
 57       <parameter>
 58         <parameterName value="@UserId" />
 59         <dbType value="String" />
 60         <size value="20" />
 61         <layout type="log4net保存到数据库中.MyLayout">
 62           <conversionPattern value="%Property{UserID}" />
 63         </layout>

 82       </parameter>-->
 83       <!--自定义Message -->
 84       <parameter>
 85         <parameterName value="@Message" />
 86         <dbType value="String" />
 87         <size value="200" />
 88         <layout type="log4net保存到数据库中.MyLayout">
 89           <conversionPattern value="%Property{Message}" />
 90         </layout>
 91       </parameter>
 92       <!--异常信息Exception -->
 93       <parameter>
 94         <parameterName value="@exception" />
 95         <dbType value="String" />
 96         <size value="2000" />
 97         <layout type="log4net.Layout.ExceptionLayout" />
 98       </parameter>
 99     </appender>
100     <root>
101       <!--配置可输出日志级别-->
102       <level value="all"/>
103       <!--应用配置-->
104       <appender-ref ref="AdoNetAppender"/>
105     </root>
106   </log4net>
107   
108 </configuration>

3.在项目中的Properties中AssemblyInfo.cs的末尾添加
 1 [assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]  

4.添加实体类：LogEntity.cs 

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 
 6 namespace log4net保存到数据库中
 7 {
 8     public class LogEntity
 9     {
10         public string UserID { get; set; }
11         public string UserName { get; set; }
12 
13         public string Message { get; set; }
14     }
15 }
