Spring Core 6.1.4 · org.springframework.core.PrioritizedParameterNameDiscoverer

ParameterNameDiscoverer implementation that tries several discoverer delegates in succession. Those added first in the addDiscoverer method have the highest priority. If one returns null, the next will be tried.

The default behavior is to return null if no discoverer matches.
