RestTemplate GET with parameteres with Spring Boot Controller - rest

Question

I'm creating a microservice that recieves data from Rest Template requests to API. I run microservice at localhost:8080 and API at localhost:13001 and test it with Postman. Test method returns String. And there is an issue when request has parameteres. With code below I always get "404 Not Found". But when API controller don't have any parameteres - method works. Can't solve this problem.
Sequence:
1) Postman (GET http://localhost:8080/test)
2) Microservice Controller (Rest Template exchange) --> code below
#RequestMapping(
method = [RequestMethod.GET],
produces = [MediaType.APPLICATION_JSON_VALUE],
path = ["/test"],
params = ["workspace_id"]
)
#ResponseBody
fun test(
authentication : OAuth2Authentication,
#RequestParam(value = "workspace_id")
workspaceId : UUID
) : String
{
return serviceDashboard.get(authentication, workspaceId)
}
3) Rest Template (GET http://localhost:13001/test?workspace_id=......) --> code below
#Autowired
lateinit var restTemplate : RestTemplate
override fun get(
authentication : OAuth2Authentication,
workspaceId : UUID
) : String
{
//Header
val token = (authentication.details as OAuth2AuthenticationDetails).tokenValue
val headers = HttpHeaders()
headers.setBearerAuth(token)
val entity = HttpEntity<Any>(headers)
//Parameters
val params = HashMap<String, UUID>()
params["workspace_id"] = workspaceId
//URI
val endpoint = URI.create("http://localhost:13001/test")
return restTemplate.exchange(endpoint.toString(), HttpMethod.GET, entity, String::class.java, params).body!!
}
4) API Controller (return data) --> code below
----------- Non-working version ----------------
#GetMapping(
produces = [MediaType.APPLICATION_JSON_VALUE],
params = ["workspace_id"],
path = ["/test"])
#ResponseBody
fun test(
#RequestParam(value = "workspace_id")
workspaceId : UUID
) : String
{
if ( workspaceId.toString() == "650a539a-0356-467e-a0d0-71d472c41aae") return "It works"
else return "It doesn't work"
}
----------- Working version ----------------
#GetMapping(
produces = [MediaType.APPLICATION_JSON_VALUE]
path = ["/test"])
#ResponseBody
fun test() : String
{
return "It works"
}

What is the annotation you are using at Class level.
You need to use #RestController.
