一 概述
1.1 概述
我们在本地开发，在配置文件中配置了Mybatis的相关参数，将sql语句输入到控制台上，但是在生产上我们为了排错或者查看sql的执行过程，就需要查看日志，所以Mybatis执行sql不仅要能在控制台打印输出，还要能写入日志文件待查。之前看过的好多博客只是解决了日志向控制台打印的问题。怎么将日志写到制定的文件，遇到了好了问题，无法将日志写到制定的文件中，
麻蛋，网上一堆资料，都是瞎比咧咧，解决不了问题，自己通过专研，终于实现了将日志输入到制定的文件当中。由于Mybatis执行sql的日志级别为DEBUG，一般生产上需要的日志级别为INFO及以上。如果将DEBUG级别日志全部写入日志文件，会造成日志查问题的速度降低，难度大大提高。
所以建议：将Mybatis执行sql的日志只能向更高日志级别的日志文件追加或单独写入一个文件。
1.2 解决办法
当时配置好springboot和logback，无法将mybaits的sql语句写入到制定文件的原因是，日志的输出方式没有配对
将 log-impl: org.apache.ibatis.logging.stdout.StdOutImpl 改为：log-impl: org.apache.ibatis.logging.slf4j.Slf4jImpl
应该配置成：
1.3 logback中onmatch与onmismatch的区别
