spring-data-rest generating wrong entity links in proxy setup

Question

I deployed my Spring Boot application behind an Apache powered reverse proxy. This proxy already sets the headers X-Forwarded-Proto and X-Forwarded-Host correctly. However, spring-data-rest generates weird entity and enpoint links. Eg requesting the news resource:

GET https://myproxyhost.net/api/news

responses with this:

{
  "_embedded" : {
    "news" : [ {
      "title" : "Testnews",
      "_links" : {
        "self" : {
          "href" : "https://myproxyhost.net/api/news/api/news/1"
        },
        "news" : {
          "href" : "https://myproxyhost.net/api/news/api/news/1{?projection}",
          "templated" : true
        }
      }
    } ]
  },
  "_links" : {
    "self" : {
      "href" : "https://myproxyhost.net/api/news/api/news"
    },
    "profile" : {
      "href" : "https://myproxyhost.net/api/news/api/profile/news"
    },
    "search" : {
      "href" : "https://myproxyhost.net/api/news/api/news/search"
    }
  },
  "page" : {
    "size" : 20,
    "totalElements" : 1,
    "totalPages" : 1,
    "number" : 0
  }
}

As you can see the links are somehow doubled and I have no idea why. The only spring-data-rest specific property I use is:

spring.data.rest.base-path=/api

Additionally in my local setup everything works fine, so I guess the proxy is somehow responsible for this.

Has anybody an idea what is going wrong here? Thanks in advance!

Answer 1

The problem was an incorrect configuration of the ReverseProxy settings which led to urls like

http://proxiedhost.net:8080//api/news

Which led therefore to the weird urls mentioned in the question above.
