当我更改写入日志的文件时，我遇到此错误
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="ConsoleAppender" target="SYSTEM_OUT">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger{36} - %msg%n"/>
</Console>
<File name="FileAppender" fileName="logs/api.log" append="false">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</File>
</Appenders>
<Loggers>
<Root level="INFO">
<AppenderRef ref="ConsoleAppender" />
<AppenderRef ref="FileAppender" />
</Root>
<Logger name="myPackage" level="DEBUG" additivity="false">
<AppenderRef ref="ConsoleAppender" />
<AppenderRef ref="FileAppender" />
</Logger>
</Loggers>
</Configuration>
这是更改添加日志的文件的方法
public static void updateLogger(String fileName, String appenderName, String packageName) {
LoggerContext context = (LoggerContext) LogManager.getContext(false);
Configuration configuration = context.getConfiguration();
Layout<? extends Serializable> oldLayout = configuration.getAppender(appenderName).getLayout();
// Delete old appender/logger
configuration.getAppender(appenderName).stop();
configuration.removeLogger(packageName);
// Create new appender/logger
LoggerConfig loggerConfig = new LoggerConfig(packageName, Level.ALL, false);
FileAppender appender = FileAppender.newBuilder()
.withFileName(fileName)
.withAppend(true)
.setName(appenderName)
.setLayout(oldLayout)
.build();
appender.start();
loggerConfig.addAppender(appender, Level.ALL, null);
configuration.addLogger(packageName, loggerConfig);
context.updateLoggers();
}
这里是我调用该方法的地方
FileUtils.updateLogger("logs/logs/log" + ".txt", "FileAppender", "mypackage");Spring Boot中更改日志文件时出错 - 日志写入成功，但出现错误

我希望深入了解发生此错误的原因并寻求潜在解决方案的指导。该场景涉及动态更改我的 Spring Boot 应用程序中的日志文件。尽管日志已成功写入新文件，但错误消息不断出现，我也希望日志也附加到控制台。如果您能帮助我理解为什么会发生此错误以及如何解决它，我将不胜感激。谢谢！
您收到状态记录器错误的直接原因是您从“myPackage”记录器配置中删除了附加程序，但没有从根记录器配置中删除它。
如果您想从所有记录器配置中删除附加程序并停止它，请运行：
// Removes from all logger configuration and stops the appender
configuration.removeAppender(appenderName);
// Now we can also remove the logger configuration
configuration.removeLogger(packageName);
如果您想从仅一个特定的记录器配置中删除附加程序，您需要：
LoggerConfig#removeAppenderConfiguration#getLoggers
