<T> ParamConverter<T> getConverter(java.lang.Class<T> rawType, java.lang.reflect.Type genericType, java.lang.annotation.Annotation[] annotations)
ParamConverter that can provide from/to string conversion
for an instance of a particular Java type.T - the supported Java type convertible to/from a String format.rawType - the raw type of the object to be converted.genericType - the type of object to be converted. E.g. if an String value
representing the injected request parameter
is to be converted into a method parameter, this will be the
formal type of the method parameter as returned by Class.getGenericParameterTypes.annotations - an array of the annotations associated with the convertible
parameter instance. E.g. if a string value is to be converted into a method parameter,
this would be the annotations on that parameter as returned by
Method.getParameterAnnotations().null.
