Log print sql when using mybatis/ibatis in SpringBoot
The console prints the sql corresponding to mybatis/ibatis
Just add the following configuration in the configuration file and adjust the log output level you want to see your sql print log in the console.
(For example, the configuration format of .properties, if it is in yaml format, you can modify it yourself)
# 配置sql日志的打印级别（这里设置成自己mapper的所在路径）
logging.level.com.xxx.jay.cust.mapper=info
Print the sql corresponding to mybatis/ibatis in the log file of the host
After completing the first configuration, it is found that the sql corresponding to the service is still not printed in the log file (app.log or catalina.out) of the host. The reason is that the output mode of the mybatis print log configured in the configuration file uses org.apache.ibatis.logging.stdout.StdOutImpl.
Checking the StdOutImpl class, it is found that the print is the System.out.println() console output print, so the sql corresponds The log is under console.log on the host.
# 配置mybatis输出日志的方式，使用的为默认的StdOutImpl
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
You can customize the output mode of mybatis print log according to StdOutImpl, and configure it as your own output mode class in the configuration file. You can print the SQL corresponding to the service in the log file (app.log or catalina.out) of the host to facilitate the location of online problems.

mybatis.configuration.log-impl=com.xxx.jay.utils.SqlLogUtils
Complete the above two steps: 1. Define the type of mybatis output log you want. 2. The configuration file is configured as a newly defined class.
It can be realized that the sql printed when using mybatis/ibatis is output in the host log
