getParameterNames

@Nullable
public String[] getParameterNames(Method method)

Description copied from interface: ParameterNameDiscoverer

Return parameter names for a method, or null if they cannot be determined.

Specified by:

getParameterNames in interface ParameterNameDiscoverer

Parameters:

method - the method to find parameter names for

Returns:

an array of parameter names if the names can be resolved, or null if they cannot
