用下面的java代码以编程方式创建一个附加器，我需要用我的partternLayout添加MDC

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.PatternLayout;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.ConsoleAppender;
import ch.qos.logback.core.encoder.LayoutWrappingEncoder;
import org.slf4j.LoggerFactory;

public class AppenderExample {
    public static void main(String[] args) {
        // 创建LoggerContext对象
        LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();

        // 创建附加器
        ConsoleAppender<ILoggingEvent> appender = new ConsoleAppender<>();
        appender.setContext(loggerContext);

        // 创建PatternLayout对象，并设置格式
        PatternLayout patternLayout = new PatternLayout();
        patternLayout.setPattern("%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n");
        patternLayout.setContext(loggerContext);
        patternLayout.start();

        // 创建LayoutWrappingEncoder对象，并设置PatternLayout
        LayoutWrappingEncoder<ILoggingEvent> encoder = new LayoutWrappingEncoder<>();
        encoder.setContext(loggerContext);
        encoder.setLayout(patternLayout);
        encoder.start();

        // 设置附加器的编码器
        appender.setEncoder(encoder);

        // 设置附加器的阈值
        appender.setThreshold(Level.ALL);

        // 将附加器添加到Logger对象中
        Logger logger = loggerContext.getLogger("com.example");
        logger.addAppender(appender);

        // 设置MDC的值
        logger.debug("Setting MDC value");
        MDC.put("key", "value");

        // 输出日志
        logger.info("Hello, World!");

        // 清除MDC的值
        MDC.clear();
    }
}
