Error page

The default 404, 500 processing in the Blade program is output directly in the interface. If you want to use a html page rendering error page, you can customize it. Set mvc.view.404=my_404.html in the app.properties configuration file. The my_404.html here should be in the templates root directory, and you can get the title, message, stackTrace built-in variables (the stackTrace is only needed when a 500 error occurs).

Let’s take an example. By default, 404 will appear in the interface:

404 Not Found - /someurl

We can define an error page named my_404.html stored in the templates directory, whose content is:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>${title}</title>
  </head>
  <body>
    My 404 Page: ${message}
  </body>
</html>

Remember to add mvc.view.404=my_404.html to the application.properties configuration file. Try opening an unknown page again:

My 404 Page: /someurl
