現(xiàn)象
springboot+logback本地調(diào)試有sql日志，但是生產(chǎn)環(huán)境日志文件中沒(méi)有sql日志
解決
①注釋掉#mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
注釋掉就可以在生產(chǎn)打印sql日志，如果不注釋?zhuān)荒茉诳刂婆_(tái)打印sql
②主要是logback配置文件中
<logger name="com.keji.xiangmu" level="DEBUG"/>?
name原來(lái)是帶*號(hào)的盯捌，但是發(fā)現(xiàn)識(shí)別不了纤壁，打印不了日志轿亮，所以就具體到每一個(gè)dao的路徑空凸，或者寫(xiě)一個(gè)總路徑避矢，
完整的logback-spring.xml日志文件如下：
```
<configuration>
<property name="LOG_HOME" value="logs" />
<appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">

</appender>
