To print MyBatis logs to a file, you can follow these steps:

  1. Firstly, make sure that the dependencies for slf4j and logback have been added to your project. These two libraries can assist you with managing and printing logs.
  2. Create a file named logback.xml in the project’s classpath to configure the way logs are outputted and formatted. This file can be placed in the src/main/resources directory.
  3. You can use the following configuration in the logback.xml file to output logs to a file:
<configuration>
  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <File>/path/to/your/log/file.log</File>
    <encoder>
      <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>
  <root level="DEBUG">
    <appender-ref ref="FILE" />
  </root>
</configuration>

/path/to/your/log/file.log is the path where you want to output the log file in the above configuration. You can modify this path according to your actual needs.

  1. recordback
<configuration>
  <!-- 其他配置项 -->
  <settings>
    <setting name="logImpl" value="LOG4J2" />
  </settings>
</configuration>

In the configuration above, setting the value of logImpl to LOG4J2 indicates using logback for log management.

Now, when you run MyBatis, it will output logs to the specified file. Make sure your application has permission to access the specified file path.
