Spring Async: How to call spring hateoas ControllerLinkBuilder inside Async method

Question

I am calling ControllerLinkBuilder.linkTo method inside a spring Async method and it fails to find the current request.

service.setUrl(linkTo(Controller.class, Controller.METHOD_GET,
                headers.getFirst(HEADER_SOURCE), id).toString());

Exception:

java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Could not find current request via RequestContextHolder
Caused by: java.lang.IllegalStateException: Could not find current request via RequestContextHolder

Answer 1

I tried to reconstruct your problem and weren't able to. Have you tried using something like the following?

linkTo(methodOn(EnvironmentRequestStateTransitioner.class)
    .approveRegistrationRequest(23L))
    .withRel("approve")

That worked fine for me using spring-boot-starter-parent version 1.3.2.RELEASE.

Complementing the _Manan reponse, You can set the attribute inheritance to true on your properties file. Please add the following line:

spring.freemarker.request-context-attribute=true
