java.lang.Object org.springframework.core.PrioritizedParameterNameDiscoverer
public class PrioritizedParameterNameDiscoverer
ParameterNameDiscoverer implementation that tries several ParameterNameDiscoverers
in succession. Those added first in the addDiscoverer
method have
highest priority. If one returns null
, the next will be tried.
The default behavior is always to return null
if no discoverer matches.
