public String[] getParameterNames(Method method)

Implements org.springframework.core.ParameterNameDiscoverer.getParameterNames.

Doc from org.springframework.core.ParameterNameDiscoverer.getParameterNames.

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

Individual entries in the array may be null if parameter names are only available for some parameters of the given method but not for others. However, it is recommended to use stub parameter names instead wherever feasible.

Parameters
method:Method

the method to find parameter names for

Returns:String[]

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