The problem is when a form POST happens and then the controller does a redirect it seems that the redirect does not know it is behind Zuul.
Form:
@RequestMapping(value = "/create-something", method = RequestMethod.GET)
public String getForm(Model model, @CookieValue(value = "XSRF-TOKEN", defaultValue = "none", required=true) String token) {
model.addAttribute("title", "Create New Something");
model.addAttribute("_csrf", token);
return "views/create-something";
}
POST:
@RequestMapping(value = "/create-something", method = RequestMethod.POST)
public String postForm(Model model, @ModelAttribute Something something) {
SomethingClient.createSomething(something);
return "redirect:" + something.getName() + "/";
}
This setup will result in the redirect trying to hit the internal IP of the UI service not the public Zuul URL.
After trying different approaches I finally settled on a direct URL. Not sure if there is a better solution but this does work and resolves the above problem.
New POST:
@RequestMapping(value = "/create-something", method = RequestMethod.POST)
public String postForm(Model model, @ModelAttribute Something something) {
SomethingClient.createSomething(something);
return "redirect:http://domain.com/ui/" + something.getName() + "/";
}
Another thought would be an interceptor. That felt like added complexity times a large number of UI services.
