logback.xml的使用，将日志异步保存到数据库中

想要把日志异步保存到数据库中，首先需要创建一个数据库，然后创建三张固定的表：

https://github.com/xiaorenwu-dashijie/logback.git

xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
    
    <property name="LOG_HOME" value="/home/logs" />
    
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

            <pattern>%X{ip} %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{150} - %msg%npattern>
        encoder>
    appender>
      
    <appender name="INFO" class="ch.qos.logback.core.rolling.RollingFileAppender">  
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

        encoder>

在记录日志的时候，我们可能有这种需求，对于每个记录除了知道日志信息外，也要记录访问该系统的IP。

MDC便提供了这个功能，只需要在代码中添加下面的方法即可

MDC.put("ip", ip);

在配置文件中用下面的方式获取即可

%X{ip}
