SLF4J-根据标签记录到不同的文件

我有一个要求，我需要创建日志文件，以使基于标签（最好是文本）的所有日志都需要记录到相应的日志文件中。

例如，

我有关于苹果，橙子和芒果的日志。

logger.info("Apples: They are red in color");
logger.info("Oranges: They are orange in color");
logger.info("Mangoes: They are yellowish in color");

按我的要求，第一个日志应记录到Apples.log，第二个Oranges.log和第三至Mangoes.log

日志文件应动态创建。

下面显示的是我的logback.xml文件

    <statusListener class="ch.qos.logback.core.status.NopStatusListener"/>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <Pattern>
                %d %-5p - %marker%m%n
            </Pattern>
        </encoder>
    </appender>
  <appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender">
    <discriminator>
      <key>fruitName</key>
      <defaultValue>Common_logs</defaultValue>
    </discriminator>
    <sift>
      <appender name="FILE-${instanceName}" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  
            <fileNamePattern>./Logs/${fruitName}/${instanceName}.log</fileNamePattern>
            <maxHistory>50</maxHistory>
            <cleanHistoryOnStart>false</cleanHistoryOnStart>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <encoder>
            <pattern>%d %-5p - %m%n</pattern>
        </encoder>
        </appender>
    </sift>
  </appender>

  <logger name="AssetInstanceService" level="info" additivity="false">
    <appender-ref ref="CONSOLE"/>
    <appender-ref ref="FILE"/>
    <appender-ref ref="SIFT" />
  </logger>

  <root level="info">
    <appender-ref ref="SIFT" />
    <appender-ref ref="CONSOLE"/>
    <appender-ref ref="FILE"/>
  </root>
</configuration>```
下面给出的是我的LogManager.java文件

package Data;

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

import ch.qos.logback.classic.LoggerContext; import ch.qos.logback.classic.joran.JoranConfigurator; import ch.qos.logback.core.joran.spi.JoranException;

public class LogManager {

static String configFile = "./logback.xml";

private static Logger _logger = LoggerFactory.getLogger(LogManager.class);
private static boolean _isInitialized = false;

private LogManager() {

}

public static Logger Instance() {
    if (_logger == null) {
        _logger = LoggerFactory.getLogger(LogManager.class);
    }
    return _logger;
}

public static Logger Instance(String instanceName) {
    if (!_isInitialized) {
        if (!CommonMethods.CheckFileExist(configFile)) {
            configFile = "../logback.xml";
            if (!CommonMethods.CheckFileExist(configFile)) {
                return null;
            }
        }
        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        JoranConfigurator configurator = new JoranConfigurator();
        lc.reset();
        configurator.setContext(lc);
        try {
            configurator.doConfigure(configFile);
            MDC.put("fruitName", instanceName);
        } catch (JoranException e) {
            System.out.println(e);
        }
        _isInitialized = true;
    }
    if (_logger == null) {
        _logger = LoggerFactory.getLogger(LogManager.class);
    }
    return _logger;
}

}``` 在这里，当我在main方法中初始化记录器时，运行jar文件时会创建我的日志。

但是我需要根据日志中的标记或ID创建具有不同名称的不同日志文件。
