Class FileServiceBuilder

java.lang.Object
com.linecorp.armeria.server.file.FileServiceBuilder
public final class FileServiceBuilder extends Object
Builds a new FileService and its FileServiceConfig. Use the factory methods in FileService if you do not override the default settings.

  • Method Details

    • clock

      public FileServiceBuilder clock​(Clock clock)
      Sets the Clock that provides the current date and time.

    • maxCacheEntries

      public FileServiceBuilder maxCacheEntries​(int maxCacheEntries)
      Sets the maximum allowed number of cached file entries. If not set, up to 1024 entries are cached by default.

    • entryCacheSpec

      public FileServiceBuilder entryCacheSpec​(String entryCacheSpec)
      Sets the Caffeine specification string of the cache that stores the content of the HttpFiles read by the FileService. If not set, Flags.fileServiceCacheSpec() is used by default.

    • serveCompressedFiles

      public FileServiceBuilder serveCompressedFiles​(boolean serveCompressedFiles)
      Sets whether pre-compressed files should be served. FileService supports serving files compressed with gzip, with the extension ".gz", and brotli, with the extension ".br". The extension should be appended to the original file. For example, to serve index.js either raw, gzip-compressed, or brotli-compressed, there should be three files, index.js, index.js.gz, and index.js.br. By default, this feature is disabled.

      Some tools for precompressing resources during a build process include gulp-zopfli and gulp-brotli, which by default create files with the correct extension.

    • maxCacheEntrySizeBytes

      public FileServiceBuilder maxCacheEntrySizeBytes​(int maxCacheEntrySizeBytes)
      Sets the maximum allowed size of a cached file entry. The file bigger than this value will not be cached. If not set, 65536 is used by default.

    • autoIndex

      public FileServiceBuilder autoIndex​(boolean autoIndex)
      Sets whether FileService auto-generates a directory listing for a directory without an index.html file. By default, this feature is disabled. Consider the security implications of when enabling this feature.
