Based on your comments & question for migration this is what I am suggesting:<\/p>\n

Map<LinkRelation, Optional<Link>> links = new HashMap<LinkRelation, Optional<Link>>();\n\nlinks.put(IanaLinkRelations.SELF, Optional.of(response.getLink(IanaLinkRelations.SELF)));\n\nlinks.put(IanaLinkRelations.NEXT, Optional.of(response.getLink(IanaLinkRelations.NEXT)));\n\nlinks.put(IanaLinkRelations.PREVIOUS, Optional.of(response.getLink(IanaLinkRelations.PREVIOUS)));\n<\/code><\/pre>\n
….<\/p>\n
\/\/calling addLinlk<\/code><\/p>\n
addLink(apmCoreBaseUrl, response, links, IanaLinkRelations.SELF);\n\naddLink(apmCoreBaseUrl, response, links, IanaLinkRelations.NEXT);\n\naddLink(apmCoreBaseUrl, response, links, IanaLinkRelations.PREVIOUS);\n<\/code><\/pre>\n
And inside addLink:<\/p>\n
private void addLink(String baseUrl, RegistrationsResource response, Map<LinkRelation, Optional> links, LinkRelation rel) {\n\n    links.get(rel).ifPresent(x->{\n     Link link = x;\n     String href = baseUrl;\n    if (link.getHref().contains(\"?\")) {\n      href = href + link.getHref().substring(link.getHref().indexOf('?'));\n    }\n    link = Link.of(href, rel);\n    response.add(link);\n    });\n  }\n<\/code><\/pre>\n
Tested with Java 11 & spring-hateoas 1.5.0. If you have any different versions, please let me know.<\/p>\n
Edit<\/strong><\/p>\n
As per OP mentioned, they are using hateoas version 2.6.7<\/code>.
\nThe response<\/code> reference in OP’s code is custom class which extending RepresentationModel<\/a>. So response.getLink(..)<\/code> will return type of Optional<Link><\/code>.
\nSo below workaround will work :<\/p>\n
Map<LinkRelation, Optional<Link>> links = new HashMap<LinkRelation, Optional<Link>>();\n\nlinks.put(IanaLinkRelations.SELF, response.getLink(IanaLinkRelations.SELF));\n<\/code><\/pre>\n
…<\/p>\n
No changes in addLink<\/code> & no changes in calling addLink<\/code> required, my original answer still valid for other operations.<\/p>\n<\/p><\/div>\n
