通过接口修改logback日志级别

@GetMapping("setLoggerLevel")
    public R setLogger(String level, HttpServletRequest request) {
        String packageName = "com.xxx.xxx.xxx";
        LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
        switch (level) {
            case "error":
                loggerContext.getLogger(packageName).setLevel(Level.ERROR);
                break;
            case "warn":
                loggerContext.getLogger(packageName).setLevel(Level.WARN);
                break;
            case "info":
                loggerContext.getLogger(packageName).setLevel(Level.INFO);
                break;
            case "debug":
                loggerContext.getLogger(packageName).setLevel(Level.DEBUG);
                break;
            default:
                return R.error("参数错误");
        }
        return R.ok("日志级别已经设置为" + level);
    }
