最近在做一个项目的时候,需要增加一个日志的功能,需要使用Log4Net记录日志,把数据插入到Oracle数据库,经过好久的研究终于成功了。把方法记录下来,以备以后查询。
直接写实现方法,分两步完成:
1、使用NuGet Manager管理工具,增加对Oracle.ManagedDataAccess.dll的引用。
2、配置具体的文件。
<?xml version="1.0"?>
<configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections><appSettings>
<add key="log4net.Internal.Debug" value="true "/> </appSettings> <log4net> <!-- 产生数据的脚本 Create table T_LogHistory ( id NUMBER not null, log_date DATE not null, log_thread VARCHAR2(50) not null, log_level VARCHAR2(50) not null, log_logger VARCHAR2(150) not null, log_operator VARCHAR2(50) not null, log_message VARCHAR2(500) not null, log_iP VARCHAR2(50) not null, log_machineName VARCHAR2(50) not null, log_browser VARCHAR2(50) not null, log_location VARCHAR2(500) not null, log_exception VARCHAR2(1500) not null, constraint pk_LogHistory primary key(id) ); Create Sequence seq_LogHistory_ID minvalue 1 maxvalue 9999999999999999999999999999 start with 1 increment by 1 nocache; --> <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender,log4net"> <!--BufferSize为缓冲区大小,只有日志记录超设定值才会一块写入到数据库--> <bufferSize value="1" /> <!--或写为<param name="BufferSize" value="10" />--><!--引用-->
