Configure the PathMatcher to use to match the destinations of incoming
messages to
@MessageMapping and
@SubscribeMapping methods.
By default
org.springframework.util.AntPathMatcher is configured.
However applications may provide an
AntPathMatcher instance
customized to use "." (commonly used in messaging) instead of "/" as path
separator or provide a completely different PathMatcher implementation.
Note that the configured PathMatcher is only used for matching the
portion of the destination after the configured prefix. For example given
application destination prefix "/app" and destination "/app/price.stock.**",
the message might be mapped to a controller with "price" and "stock.**"
as its type and method-level mappings respectively.
When the simple broker is enabled, the PathMatcher configured here is
also used to match message destinations when brokering messages.
