spring cloud set logging.level does not work in application.yml(I have a logback-spring.xml, too) - spring

Question

these screenshot are my configurations about logback
logback-spring.xml
<root level="info">
<appender-ref ref="FILE"/>
<appender-ref ref="STDOUT"/>
</root>
application.properties
logging.file.path=./logs
logging.level.cn.hsa=debug
logging.level.root=info
logging.level.org.springframework.web=trace
It’s not working when i change logging.level.root to debug or others in application.properties, it's always use this configure in logback-spring.xml
I read spring source code, logback-srping.xml loaded before application.properties
but i dont know why these configures were not override

You can define something like this if you want to customize:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<springProperty scope="context" name="LOG_PATH" source="app.log.path"
defaultValue="your_log_path" />
<timestamp key="dateStamp" datePattern="yyyy-MM-dd" />
<appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<Pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
</Pattern>
</encoder>
</appender>
<springProfile name="test,prod">
<appender name="Access-FileAppender"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>${LOG_PATH}/logs/xyz.%d{yyyy-MM-dd}.log
</fileNamePattern>
<!-- keep 90 days' worth of history -->
<maxHistory>90</maxHistory>
</rollingPolicy>
<encoder>
<Pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
</Pattern>
</encoder>
</appender>
<appender name="Async-Access-FileAppender" class="ch.qos.logback.classic.AsyncAppender">
<appender-ref ref="Access-FileAppender" />
</appender>
</springProfile>
<root>
<level value="INFO" />
<appender-ref ref="consoleAppender" />
</root>
<springProfile name="local">
<logger name="com.xxx.yyy" level="DEBUG" additivity="false">
<appender-ref ref="consoleAppender" />
</logger>
</springProfile>
<springProfile name="dev">
<logger name="com.xxx.yyy" level="DEBUG" additivity="false">
<appender-ref ref="consoleAppender" />
</logger>
</springProfile>
<springProfile name="test,prod">
<logger name="com.xxx.yyy" level="INFO" additivity="true">
<appender-ref ref="consoleAppender" />
</logger>
</springProfile>
</configuration>
As you can see, test/prod have the similar logging configuration. Similarly, you can configure for local and dev as well.
Hope this helps.
