Let's get to the topic. Let's talk about a problem I solved today. Anyone who has used JSF knows that in JSF (a project that uses the JSF framework), the jump between pages is navigated through faces- config.xml files. Of course, you can do page jumps in other ways, but JSF doesn't recommend it. When doing page navigation, there is a "redirect" option, that is, "redirect". The code is as follows:
/ archives/admin/archivesAudit.jsp
AuditFinish
/ archives/admin/archivesBrowse.jsp
If you do not select this option, after jumping from the current page to another page, the address bar retains the requested URL,server as a forwarding action; if you select "redirect", the requested URL,server in the address bar will resend a requested URL. Of course, the rendered page is normal regardless of whether you make the "redirect" choice or not. However, if you are jumping from the add, modify, delete, etc. Pages to the list page. If you do not add "redirect" for navigation, when the list page is refreshed again after a successful submission, the action of the last submission will be performed again. The result is that the last addition, modification, or deletion will be done over and over again, and it is all the same data. Because the list page retains the same address as the last submitted URL, that's why the last committed action is performed. The solution is to add the "redirect" option when navigating the page!
