How can the file directory be dynamically set in logback?

To dynamically set the directory for Logback files, you can follow these steps:

1. LoggerContext from ch.qos.logback.classic
2. Woodcutter
3. Contextual Logging Framework
4. obtain the logger

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
Logger logger = loggerContext.getLogger("loggerName");

1. a FileAppender from ch.qos.logback.core

FileAppender<ILoggingEvent> fileAppender = new FileAppender<>();
fileAppender.setFile("path/to/log/file.log");
logger.addAppender(fileAppender);

1. Start the LoggerContext.

loggerContext.start();

This allows the dynamic configuration of Logback’s file directory. It is important to note that this code snippet needs to be executed when the application starts. If you need to change the file directory at runtime, you can repeat the steps above. Make sure to stop the LoggerContext before changing the file directory, and then start it again.
