Using spring-hateoas:1.2.1 with Spring Boot 2.4.0:
When a REST controller class annotated with @RequestMapping("${some-variable}/resources") returns a resource extending RepresentationModel, I get the following error :
{
"label": "uncatched exception",
"detailMessage": "Not enough variable values available to expand 'some-variable'",
"statusCode": 500
}
I pinned the issue to this suspect line in the core library :
|
WebApplicationContext context = ContextLoader.getCurrentWebApplicationContext(); |
From what I could read, ContextLoader.getCurrentWebApplicationContext() doesn't return the expected context when using Spring Boot, and it's actually returning null when I place a breakpoint there :
You can see (L.92) that the resolvePlaceholders method won't be called, explaining my error since the raw string is passed on.
Any idea on how we could fix this ? :)
