x-forwarded-proto broken in Spring Boot 2.1.1

For the following test:

@Test
fun `GET links uses proto headers`() {
     mvc.perform(get("/v1/").header("x-forwarded-proto", "https"))
              .andExpect(status().isOk)
              .andExpect(jsonPath("$._links.activate.href", startsWith("https")))
}

And the following implementation:

private fun buildLinkForUser(currentUser: User) =  
entityLinks.linkToCollectionResource(UserResource::class.java).withRel("activate")

Or alternatively with controller links, e.g.:

fun buildLinkForUser(): Link = linkTo(methodOn(UserController::class.java).activate())
                .withRel("activate")

I get the test passing in Spring Boot 2.0.7 and failing in Spring Boot 2.1.1 - because the link gets http instead of https.

I checked Spring Hateoas in both boot releases and it remains 0.25.0. Obviously, this makes me think this issue doesn’t belong here. However, I was hoping you could help me reassign it where it belongs?

For future readers, use-forward-headers has been deprecated in favour of forward-headers-strategy:

server.forward-headers-strategy=native

forward-headers-strategy defaults to none.

Spring Framework now defaults with Forwarded header support disabled. So you have to use that setting for any apps you need from here on.

I’ll consult with @odrotbohm about seeing if we can get a patch release out the door.
