How to specify the output path of pig register Project Log

springboot,logback-spring.xml Don't take effect

Usually springboot project ,
Just in src/main/resources Add below logback-spring.xml that will do ,

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">
	<property name="log.path" value="/opt/pig/logs/${project.artifactId}"/>
	<!--  Color log format  -->

	<!-- Console log output -->
	<appender name="console" class="ch.qos.logback.core.ConsoleAppender">

	</appender>

	<!-- Log file debug output -->
	<appender name="debug" class="ch.qos.logback.core.rolling.RollingFileAppender">

	</appender>

	<!-- Log file error output -->

	</appender>

	<!-- Level: FATAL 0 ERROR 3 WARN 4 INFO 6 DEBUG 7 -->
	<root level="INFO">

	</root>
</configuration>

Then I started the project , However, it is found that no log files are generated to the configured directory ,

I'm in again application.yml Specified in logback Configuration file for ：

logging:
  config: classpath:logback-spring.xml

But it still doesn't take effect , What's going on here ？

My project is an open source project pig Registration Center for pig-register, It quoted nacos-core This jar package ,
I feel it is because of this dependence （ Because I start it locally pig-register At the time of C I have seen nacos Output log file ）, I went to see naco-core This project , Found that it had a META-INF/logback/nacos.xml,
Inside nacos Of logback The configuration file ,
Then I found it in LoggingSpringApplicationRunListener This configuration file is used in ,

LoggingSpringApplicationRunListener implements SpringApplicationRunListener

See here , I sort of understand what's going on ,

spring boot It's using LoggingApplicationListener To initialize the log system ,

System.setProperty(CONFIG_PROPERTY, DEFAULT_NACOS_LOGBACK_LOCATION);

This step will be LoggingApplicationListener Medium CONFIG_PROPERTY namely logging.config Set up in order to "META-INF/logback/nacos.xml",

And then look at nacos-core Of /META-INF/spring.factories,

Sure enough, it was designated here SpringApplicationRunListener For the front LoggingSpringApplicationRunListener,
such pig-register quote nacos-core When , Will nacos Of LoggingSpringApplicationRunListener Sign up to spring boot In the container （ When it starts ）,
such SpringApplicationRunListener I won't go again resource seek logback.xml、logback-spring.xml Such a default configuration file ,
So the configuration file we added doesn't work .

that , Is there no way to modify the log configuration ？

No, it isn't , We can do this at startup ：

nohup java -Dserver.port=8848 -Dlogging.level.root=INFO -Xmx256M -Xms256M -jar pig-register.jar --logging.config=classpath:logback-spring.xml >> /dev/null 2>&1 &

Specify to use our configuration file .

Impropriety , Also please correct me .
