你是否因?yàn)轫?xiàng)目出現(xiàn)問題，查找日志文件定位錯(cuò)誤花費(fèi)N多時(shí)間，是否為此苦不堪言，沒關(guān)系！現(xiàn)在通過這篇文章，將徹底解決你的煩惱，這篇文篇介紹，如何通過logback配置文件將日志進(jìn)行分級(jí)打印，一個(gè)配置文件徹底搞定日志查找得煩惱。

創(chuàng)建日志配置文件
在工程resources文件夾下新建文件夾log，并在該文件夾下創(chuàng)建logback.xml文件,加入以下配置：
${CONSOLE_LOG_PATTERN}
UTF-8
debug
${LOG_PATH}/log_debug.log
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
UTF-8
${LOG_PATH}/debug/log-debug-%d{yyyy-MM-dd}.%i.log
500MB
30
debug
ACCEPT
DENY
${LOG_PATH}/log_info.log
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
UTF-8
${LOG_PATH}/info/log-info-%d{yyyy-MM-dd}.%i.log
500MB
30
info
ACCEPT
DENY
${LOG_PATH}/log_warn.log
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
UTF-8
${LOG_PATH}/warn/log-warn-%d{yyyy-MM-dd}.%i.log
500MB
30
warn
ACCEPT
DENY
${LOG_PATH}/log_error.log
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
UTF-8
${LOG_PATH}/error/log-error-%d{yyyy-MM-dd}.%i.log
500MB
30
error
ACCEPT
DENY
注意：loback配置文件中
name的屬性值一定要是當(dāng)前工程的java代碼的完整目錄,因?yàn)?b>mybatis打印的日志級(jí)別是debug級(jí)別的，因此需要配置debug級(jí)別日志掃描的目錄。
