self4j 微服务日志配置-按微服务应用分别生成不同的日志文件

如题：
效果是：在/opt/myApps/logs/app1/app1.log /opt/myApps/logs/app2/app2.log 每个应用独立存储日志；

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <springProperty scope="context" name="APPLICATION_NAME" source="spring.application.name"/>
    <springProperty scope="context" name="LOG_HOME" source="logging.path"
                    defaultValue="/opt/myApps/logs"/>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n
            </pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <appender name="FILE"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_HOME}/${APPLICATION_NAME}/${APPLICATION_NAME}.log/</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/${APPLICATION_NAME}/%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxHistory>30</maxHistory>
            <timeBasedFileNamingAndTriggeringPolicy
                    class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <encoder>
            <pattern>
                %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
            </pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="FILE"/>
    </root>
</configuration>

其他补充：
springProperty 标签可以定义变量，读取springboot中的配置的值，在logback的配置文件中通过变量名来引用；
