应用场景举个例子：
当我一个服务需要启动n个端口，来监听n个来源的数据，并且处理数据逻辑一致；但是我想要它们的日志分开文件夹来打印，从而更好的分析问题，那么就可以用我下面提供的模版了；

动态生成日志logger，然后通过对象管理起来，然后我们可以从这个管理器内拿logger来打印日志，或者从LoggerFactory根据id去拿logger对象

    public void initLogger(Set<Integer> keySet) {
        // 获取 Logback 的 LoggerContext
        LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
        for (Integer port : keySet) {
            Logger logger = null;
            try {
                String currPath = bsePath + "/" + port + "/";
                // 创建 Logger
                logger = context.getLogger("LOGGER-" + port);
                logger.setLevel(Level.ALL);
                logger.setAdditive(false); // 禁止继承父 Logger 的 Appender

                // 创建 Appender
                RollingFileAppender<ILoggingEvent> appender = new RollingFileAppender<>();
                appender.setContext(context);
                appender.setName("DYNAMIC_APPENDER_" + port);
                appender.setFile(currPath + "app.log");

                // 配置滚动策略
                TimeBasedRollingPolicy<ILoggingEvent> rollingPolicy = new TimeBasedRollingPolicy<>();
                rollingPolicy.setContext(context);
                rollingPolicy.setParent(appender);
                rollingPolicy.setFileNamePattern(currPath + "log-%d{yyyy-MM-dd}.%i.log");
                rollingPolicy.setMaxHistory(3);
                rollingPolicy.setTotalSizeCap(FileSize.valueOf("7GB"));

                // 配置 SizeAndTimeBasedFNATP
                SizeAndTimeBasedFNATP<ILoggingEvent> triggeringPolicy = new SizeAndTimeBasedFNATP<>();
                triggeringPolicy.setContext(context);
                triggeringPolicy.setMaxFileSize(FileSize.valueOf("100MB"));
                triggeringPolicy.setTimeBasedRollingPolicy(rollingPolicy);
                rollingPolicy.setTimeBasedFileNamingAndTriggeringPolicy(triggeringPolicy);

                try {
                    rollingPolicy.start(); // 启动滚动策略
                } catch (Exception e) {
                    log.error("Failed to start rolling or triggering policy:", e);
                }

                // 配置编码器
                PatternLayoutEncoder encoder = new PatternLayoutEncoder();
                encoder.setContext(context);
                encoder.setPattern("%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n");
                encoder.start();
                // 设置 Appender
                appender.setRollingPolicy(rollingPolicy);
                appender.setEncoder(encoder);
                try {
                    appender.start();
                } catch (Exception e) {
                    log.error("Failed to start appender: ", e);
                }
                // 将 Appender 添加到 Logger
                logger.addAppender(appender);
                // 输出日志
                logger.info("测试日志，输出到动态路径文件:{}", currPath);
            } catch (Exception e) {
                log.error("初始化logger失败:{}", port);
                throw new RuntimeException(e);
            }
            LightManagerBo lightManagerBo = port2ManagerMap.computeIfAbsent(port, k -> new LightManagerBo());
            lightManagerBo.setLogger(logger);
        }
    }
