发帖数: 34805 | 1 I am using spring MVC, some form simply takes a while before a result can be
returned. Impatient user will click the button multiple times, is there
any built-in function in spring to prevent double submissions?
The redirect after submit will prevent browser refresh double submission,
but not double click button submission problem. |

发帖数: 34805 | 4 I'd rather rely on some server side solution.
What if user clicks quickly and the javascript is slow?
Use a token in session seems to be a good solution.
Spring has a handleInvalidSubmission function in AbstractFormController
which should be overrided.
Check google, you can do it multiple times, and you'll only
receive one email.

发帖数: 1879 | 5 Well, certainly you can also use a unique id to acompany each submission
so the duplicate submission can be easily detected, but I think that is
rather unnecessary. Another common approach is to use a time counter to
internally ignore submissions during very short durations for the same
request from the same session.
Just speaking from experiences of dealing CGI and JavaScript.

发帖数: 2416 | 6 javascript can't be relied on, but it's still useful - saves a server trip
whenever possible.
There are a few server-side solutions:
1. Set sessionForm to true in the controller. A duplicated submission would
come when there isn't a form in the session (having been consumed by the
first one), which would make it invalid. This isn't a fail-safe solution.
There can be race conditions.
2. As coconut said, generate a token/timestamp and put it in a hidden field.
If a token comes in for the second ti

What do you mean race condition? Open 2 windows and click them side
by side? If that's the case, I don't think it'll be a problem for
my current project, I'll just pick whichever to submit.

Yeah, something like that. I guess practically it's not as serious as the
race conditions in program code. Could be a little wacky if you need to run
automated load tests though.
