The java code of logback custom logger

The java code of logback custom logger:

public static Logger getLogger(String jobName, Class<?> cls){
        Logger logger = (Logger) LoggerFactory.getLogger (cls);

        LoggerContext loggerContext = logger.getLoggerContext ();
        PatternLayoutEncoder encoder = new PatternLayoutEncoder();
        encoder.setContext(loggerContext);
        encoder.setPattern("%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n");
        encoder.start();

        RollingFileAppender appender = new RollingFileAppender();
        appender.setContext(loggerContext);
        TimeBasedRollingPolicy rollingPolicyBase = new TimeBasedRollingPolicy<>();
        rollingPolicyBase.setContext(loggerContext);
        rollingPolicyBase.setParent(appender);
        rollingPolicyBase.setFileNamePattern((String.format("%s/job-schedule/mesp-schedule-%s", logFilePath, jobName) + ".%d{yyyy-MM-dd}.%i.log"));
        SizeAndTimeBasedFNATP sizeAndTimeBasedFNATP = new SizeAndTimeBasedFNATP();
        sizeAndTimeBasedFNATP.setMaxFileSize("10MB");
        rollingPolicyBase.setTimeBasedFileNamingAndTriggeringPolicy(sizeAndTimeBasedFNATP);
        rollingPolicyBase.setMaxHistory(10);
        rollingPolicyBase.start();

        appender.setEncoder(encoder);
        appender.setRollingPolicy(rollingPolicyBase);
        appender.start();

        logger.setAdditive(false);
        logger.addAppender(appender);

        return logger;
    }
