      <T> ParamConverter<T> getConverter(Class<T> rawType, Type genericType, Annotation[] annotations)
      Obtain a ParamConverter that can provide from/to string conversion for an instance of a particular Java type.
      Type Parameters:
      T - the supported Java type convertible to/from a String format.
      Parameters:
      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().
      Returns:
      the string converter, otherwise null.
