      参数:
      mimeType - the string to parse
      返回:
      the mime type
      抛出:
      InvalidMimeTypeException - if the string cannot be parsed

    • parseMimeTypes

      public static List<MimeType> parseMimeTypes(String mimeTypes)
      Parse the comma-separated string into a list of MimeType objects.
      参数:
      mimeTypes - the string to parse

      the list of mime types
      抛出:
      InvalidMimeTypeException - if the string cannot be parsed

    • tokenize

      public static List<String> tokenize(String mimeTypes)
      Tokenize the given comma-separated string of MimeType objects into a List<String>. Unlike simple tokenization by ",", this method takes into account quoted parameters.
      参数:
      mimeTypes - the string to tokenize
      返回:
      the list of tokens

    • toString

    • sortBySpecificity

      public static void sortBySpecificity(List<? extends MimeType> mimeTypes)

      参数:
      mimeTypes - the list of mime types to be sorted
      抛出:
      IllegalArgumentException - if mimeTypes contains more than 50 elements
