In log4j2, you can configure log file deletion operations using the Delete strategy. Here are some common examples of delete strategy configurations:<\/p>\n

    \n
  1. Delete older log files based on the maximum storage space of the log file.<\/li>\n<\/ol>\n
    <DefaultRolloverStrategy>\r\n    <Delete basePath=\"logs\" maxDepth=\"2\">\r\n        <IfFileName glob=\"logs\/app-*.log\" \/>\r\n        <IfLastModified age=\"7d\" \/>\r\n    <\/Delete>\r\n<\/DefaultRolloverStrategy>\r\n<\/code><\/pre>\n
    The above settings will delete app-*.log files in the logs folder that have a last modified date older than 7 days.<\/p>\n
      \n
    1. Delete old log files based on the number of log files.<\/li>\n<\/ol>\n
      <DefaultRolloverStrategy>\r\n    <Delete basePath=\"logs\" maxDepth=\"1\">\r\n        <IfFileName glob=\"logs\/app-*.log\" \/>\r\n        <IfAccumulatedFileSize exceeds=\"100 MB\" \/>\r\n    <\/Delete>\r\n<\/DefaultRolloverStrategy>\r\n<\/code><\/pre>\n
      The above configuration will remove the app-*.log files in the logs folder until the total file size exceeds 100 MB.<\/p>\n
        \n
      1. Delete old log files based on custom conditions.<\/li>\n<\/ol>\n
        <DefaultRolloverStrategy>\r\n    <Delete basePath=\"logs\" maxDepth=\"1\">\r\n        <IfFileName glob=\"logs\/app-*.log\" \/>\r\n        <If condition=\"java.nio.file.Files.isRegularFile(java.nio.file.Paths.get($${basePath}), java.nio.file.LinkOption.NOFOLLOW_LINKS) && java.nio.file.Files.getLastModifiedTime(java.nio.file.Paths.get($${basePath}), java.nio.file.LinkOption.NOFOLLOW_LINKS).toMillis() <= 0\" \/>\r\n    <\/Delete>\r\n<\/DefaultRolloverStrategy>\r\n<\/code><\/pre>\n
        The above settings will delete the app-*.log files in the logs folder if the file exists and the last modification time is less than or equal to 0.<\/p>\n
