Based on your comments & question for migration this is what I am suggesting: Map<LinkRelation, Optional<Link>> links = new HashMap<LinkRelation, Optional<Link>>(); links.put(IanaLinkRelations.SELF, Optional.of(response.getLink(IanaLinkRelations.SELF))); links.put(IanaLinkRelations.NEXT, Optional.of(response.getLink(IanaLinkRelations.NEXT))); links.put(IanaLinkRelations.PREVIOUS, Optional.of(response.getLink(IanaLinkRelations.PREVIOUS))); …. //calling addLinlk addLink(apmCoreBaseUrl, response, links, IanaLinkRelations.SELF); addLink(apmCoreBaseUrl, response, links, IanaLinkRelations.NEXT); addLink(apmCoreBaseUrl, response, links, IanaLinkRelations.PREVIOUS); And inside addLink: private void addLink(String baseUrl, RegistrationsResource response, Map<LinkRelation, Optional> links, LinkRelation … Read more

When you extend from Repository you have to provide two generics: The type of the model (postJob) The type of the ID (field with @Id) annotation In your case the @Id annotated field is a long, while your repository extends from Repository<postJob, String>. This causes trouble, because now Spring is unable to find a findOne() … Read more

Define a method like this one: public static String convert(String monthInSomeYear, Locale locale) { // create something that … Read more

Meaning sometimes you’d log in and it’d retain the proper session and you could go the the localhost:8080/ui page and not get the Whitelabel Error page… sometimes you’d still get it. On the Gateway server… 1) Added RequestMethod.POST @Controller public … Read more
I don’t know your codes, because you provided none. So I’ll try to guess. It seems like you do not say to your client he will download an image. Try adding this to your response header : Content-type: image/jpeg I’ll give some example code, but I can’t promise it will work for you. @GetMapping(path = … Read more
