Parameters
request current HTTP request
handler handler to use
Returns
  • the lastModified value for the given handler

public ModelAndView handle (HttpServletRequest request, HttpServletResponse response, Object handler)

Use the given handler to handle this request. The workflow that is required may vary widely.

Parameters
request current HTTP request
response current HTTP response
handler handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.

public boolean supports (Object handler)

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);

Parameters
handler handler object to check
Returns
  • whether or not this object can use the given handler
