Question

我想仅记录到文件并禁用控制台日志记录，但这不起作用。我认为以下应该有效，但事实并非如此。有谁知道我弄错了什么？

我正在尝试使用detachAndStopAllAppenders删除任何默认记录器，但仍然不会停止记录到控制台...

import android.util.Log;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.encoder.PatternLayoutEncoder;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.rolling.RollingFileAppender;
import ch.qos.logback.core.rolling.TimeBasedRollingPolicy;

public class FileLogger
{
    static Logger mLogger = LoggerFactory.getLogger(FileLogger.class);

    public FileLogger(FileLoggingSetup setup)
    {
        if (setup == null)
            throw new RuntimeException("You can't create a FileLogger without providing a setup!");

        init(setup);
    }

    private void init(FileLoggingSetup setup)
    {
        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        lc.reset();

        // 1) FileLoggingSetup - Encoder for File
        PatternLayoutEncoder encoder1 = new PatternLayoutEncoder();
        encoder1.setContext(lc);
        encoder1.setPattern(setup.mLogPattern);
        encoder1.start();

        // 2) FileLoggingSetup - rolling file appender
        RollingFileAppender<ILoggingEvent> rollingFileAppender = new RollingFileAppender<ILoggingEvent>();
        rollingFileAppender.setAppend(true);
        rollingFileAppender.setContext(lc);
        //rollingFileAppender.setFile(setup.mFolder + "/" + setup.mFileName + "." + setup.mFileExtension);

        // 3) FileLoggingSetup - Rolling policy (one log per day)
        TimeBasedRollingPolicy<ILoggingEvent> rollingPolicy = new TimeBasedRollingPolicy<ILoggingEvent>();
        rollingPolicy.setFileNamePattern(setup.mFolder + "/" + setup.mFileName + "_%d{yyyyMMdd}." + setup.mFileExtension);
        rollingPolicy.setMaxHistory(setup.mDaysToKeep);
        rollingPolicy.setCleanHistoryOnStart(true);
        rollingPolicy.setParent(rollingFileAppender);
        rollingPolicy.setContext(lc);
        rollingPolicy.start();

        rollingFileAppender.setTriggeringPolicy(rollingPolicy);
        rollingFileAppender.setEncoder(encoder1);
        rollingFileAppender.start();

        // add the newly created appenders to the root logger;
        // qualify Logger to disambiguate from org.slf4j.Logger
        ch.qos.logback.classic.Logger root = (ch.qos.logback.classic.Logger) mLogger;
        root.detachAndStopAllAppenders();
        root.addAppender(rollingFileAppender);
    }
}

gradle依赖

}

我正在通过mLogger.debug(logMessage);和类似的事件登录......

问题是，我在另一个库中注册另一个记录器并且log4j是全局设置的，因此我的小日志类正在登录到其他地方注册的一个记录器...
