How to make HATEOAS consider contextPath ?

[ludovic-andreas-toth]

Hi,

I have a problem described in more details here: https://stackoverflow.com/questions/61124099/context-path-not-considered-in-hateoas-links-when-upgrading-from-spring-boot-1-5.

Basically after upgrading to the latest version of spring boot(2.2.26), when using hateoas, the Links are not containing the context-path(server.servlet.context-path).

I have tried using forward-headers-strategy with both FRAMEWORK and NATIVE with a ForwardedHeaderFilter. Adiitionally, the x-forwarded-prefix cannot be set from the config with tomcat.

Are there any guidelines about how to deal with this issue or how to avoid it ?

Hmm. When I apply such a setting to spring-hateoas-examples, it works.

See spring-projects/spring-hateoas-examples#31.

If you rip out all forwarding settings and code, but keep the servlet context stuff, what happens then?

Based on no feedback and my own example working, I'm closing this issue. If you have further feedback, we can reopen this issue.

@gregturn I'm seeing this issue in my API behind Spring-Boot-Gateway. I hope it is just something I'm configuring incorrectly. I'm using Spring Boot Framework 3.0.2.

The incoming request is to localhost:8080/uswf-gateway/uswf-api/tags
The gateway is setup with:

 routes:
      - id: api
        uri: http://localhost:8081
        predicates:
        - Path=/uswf-gateway/uswf-api/**
        filters:
        - StripPrefix=1

So the gateway forwards to the API using this url: http://localhost:8081/uswf-api/tags

My API has a context-path of: /uswf-api, but my links are shows as:

"links": {
        "self": "http://localhost:8080/uswf-gateway/tags"
    }

I've tried setting server.forward-headers-strategy = framework and also the ForwardedHeaderFilter Bean as shown in the Hateoas documentation. Am I missing something?
