logback scanPeriod is not working

logback scanPeriod 配置不生效解決

必須修改 target 內部的才能生效，修改 resources的 logback.xml 不生效。
You must modify the content of target‘s logback.xml instead of that of resources.

Demo
1、logback.xml （6秒掃描一次，待會把 indi 的level改成error看效果）

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="6 seconds" debug="true">
    <!-- 控制檯輸出 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level [%thread%X{sourceThread}]%logger{24} - %msg%n</pattern>
        </encoder>
    </appender>
    
    <logger name="indi" level="info" additivity="false">
        <appender-ref ref="STDOUT"/>
    </logger>

    <!--<logger name="indi" />-->

    <root level="DEBUG">
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>

2、Demo.class

package indi.sword.logback.demo;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Demo {
    public static void main(String[] arg) throws Exception{
        Logger logger = LoggerFactory.getLogger(Demo.class);
        while(true) {
            Thread.sleep(1000);
            logger.debug("debug");
            logger.info("info");
            logger.warn("warn");
            logger.error("error");

            logger.error("======");
        }
    }
}
