Why logback StaticMDCBinder hash High priority

Question

I also wrote one org.slf4j.impl.StaticMDCBinder, but always StaticMDCBinder of logback priority loading.

How do I gracefully prioritize my org.slf4j.impl.StaticMDCBinder;

package org.slf4j.impl;

import cn.jugg.agile.core.dapper.log.JaMDCAdapter;
import org.slf4j.spi.MDCAdapter;

// my StaticMDCBinder 
public class StaticMDCBinder {

    private static final StaticMDCBinder instance = new StaticMDCBinder();

    private StaticMDCBinder() {
    }

    public static StaticMDCBinder getSingleton() {
        return instance;
    }

    public MDCAdapter getMDCA() {
        return new JaMDCAdapter();
    }
}
