Answer 1

Try on your controller

Normal GET:

return "path/to/jsp";

Redirect:

return "redirect:/login";

When use redirect prefix, it will return to http://host/yourapp/login

Spring documentation for redirect prefix

For redirect example:

@RequestMapping(value = "/logout", method = RequestMethod.GET)
public String logoit() {
    return "redirect:/";
}

Answer 2

假设您的控制器方法返回一个String，您可以执行以下操作：

return "redirect:/path/to/page";
