In logback, the log level can be configured as follows:

  1. I am a native English speaker, so I will provide a paraphrase in my native language:
    I speak English fluently, so I will rephrase it in English for you.
<root level="DEBUG">
    <appender-ref ref="CONSOLE"/>
</root>

<logger name="com.example" level="DEBUG"/>

<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>%d [%thread] %-5level %logger{35} - %msg%n</pattern>
    </encoder>
</appender>

<root level="DEBUG">
    <appender-ref ref="CONSOLE"/>
</root>

In the above configuration, the level attribute is used to set the logging level, with optional values including: ALL, TRACE, DEBUG, INFO, WARN, ERROR, OFF. Depending on the actual requirements, you can choose the appropriate logging level to output log information.
