    Description copied from interface: HandlerAdapter
    Given a handler instance, return whether or not this HandlerAdapter can support it. Typical HandlerAdapters will base the decision on the handler type. HandlerAdapters will usually only support one handler type each.
    A typical implementation:
    return (handler instanceof MyHandler);
    Specified by:
    supports in interface HandlerAdapter
    Parameters:
    handler - the handler object to check
    Returns:
    whether or not this object can use the given handler

    handle in interface HandlerAdapter
    Parameters:
