public Class ServletWebRequest

Implements org.springframework.web.context.request.WebRequest.checkNotModified.

Doc from org.springframework.web.context.request.WebRequest.checkNotModified.

Check whether the requested resource has been modified given the supplied last-modified timestamp (as determined by the application).

This will also transparently set the "Last-Modified" response header and HTTP status when applicable.

Typical usage:

public String myHandleMethod(WebRequest request, Model model) {
  long lastModified = // application-specific calculation
  if (request.checkNotModified(lastModified)) {
    // shortcut exit - no further processing necessary
    return null;
  }
  // further request processing, actually building content
  model.addAttribute(...);
  return "myViewName";
}

This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

If the "If-Modified-Since" header is set but cannot be parsed to a date value, this method will ignore the header and proceed with setting the last-modified timestamp on the response.

Parameters

lastModifiedTimestamp:long

the last-modified timestamp in milliseconds that the application determined for the underlying resource

Returns:boolean

whether the request qualifies as not modified, allowing to abort request processing and relying on the response telling the client that the content has not been modified

@Override

Implements org.springframework.web.context.request.WebRequest.checkNotModified.

Doc from org.springframework.web.context.request.WebRequest.checkNotModified.

Check whether the requested resource has been modified given the supplied ETag (entity tag), as determined by the application.

This will also transparently set the "ETag" response header and HTTP status when applicable.

Typical usage:

public String myHandleMethod(WebRequest request, Model model) {
  String eTag = // application-specific calculation
  if (request.checkNotModified(eTag)) {
    // shortcut exit - no further processing necessary
    return null;
  }
  // further request processing, actually building content
  model.addAttribute(...);
  return "myViewName";
}

Parameters

etag:String

the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.

Returns:boolean

true if the request does not require further processing.
