配置日志管理

新建logback.xml文件

大家可以根据项目修改LOG_HOME的value值,还有开发环境建议把下面这个注释掉,使用控制台输出日志,方便定位,真实环境,把控制台注释挂掉,改为日志文件输出

 logback.xml

 
<?xml version="1.0" encoding="UTF-8"?>
<!--dev env-->
<configuration>
    <!--
           fileError对应error级别,文件名以log-error-xxx.log形式命名

           fileDebug对应debug级别,文件名以log-debug-xxx.log形式命名
