Chapter 11. Understanding the HornetQ Wildcard Syntax
HornetQ uses a specific syntax for representing wildcards in security settings, address settings, and when creating consumers.
A HornetQ wildcard expression contains words delimited by the character '
.' (full stop).
The special characters '
#' and '*' also have special meaning and can take the place of a word.
The character '
#' means "match any sequence of zero or more words".
The character '
*' means "match a single word".
So the wildcard 'news.europe.#' would match 'news.europe', 'news.europe.sport', 'news.europe.politics', and 'news.europe.politics.regional' but would not match 'news.usa', 'news.usa.sport' or 'entertainment'.
The wildcard 'news.*' would match 'news.europe', but not 'news.europe.sport'.
The wildcard 'news.*.sport' would match 'news.europe.sport' and also 'news.usa.sport', but not 'news.europe.politics'.
