Logback 使用TurboFilter实现日志级别等内容的动态修改操作

public class ForceWarnFilter extends TurboFilter {
    @Override
    public FilterReply decide(Marker marker, Logger logger, Level level, String format, Object[] params, Throwable throwable) {
        if (level == Level.ERROR && logger.getName().equals("org.springframework.cloud.sleuth.instrument.web.ExceptionLoggingFilter")) {
            logger.warn(marker, format, params);
            return FilterReply.DENY;
        }
        return FilterReply.NEUTRAL;
    }
}

    <turboFilter class="com.didispace.log.filter.ForceWarnFilter" />

LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
lc.addTurboFilter(new MyTurboFilter());

 public void testLog(String key, String level, String level2){
        LoggerContext loggerContext= (LoggerContext) LoggerFactory.getILoggerFactory();
        //设置全局日志级别
        ch.qos.logback.classic.Logger logger=loggerContext.getLogger("root");
        logger.setLevel(Level.toLevel(level));

            ch.qos.logback.classic.Logger vLogger = loggerContext.getLogger(key);
            if (vLogger!=null)
                vLogger.setLevel(Level.toLevel(level2));
