The preceding example results in changing the name of the reported span to `foo bar`, just before it gets reported (for example, to Zipkin).
Sleuth registers a `SpanHandler` bean that can automatically skip reporting spans of given name patterns. The property `spring.sleuth.span-handler.span-name-patterns-to-skip` contains the default skip patterns for span names. The property `spring.sleuth.span-handler.additional-span-name-patterns-to-skip` will append the provided span name patterns to the existing ones. In order to disable this functionality just set `spring.sleuth.span-handler.enabled` to `false`.
