Answer 1

Use

@GetMapping(value= "/operation", produces = "application/json")

Call

GET:   localhost:8080/operationsOnEmployee/operation

Also, make sure you don't have any path defined in application.properties

server.servlet.context-path= #some path

Answer 2

Try to provide mapping URL inside @GetMapping to map your method as :

@GetMapping("/mappingURL")

GET URL : localhost:8080/operationsOnEmployee/mappingURL

If not clean the project and re-run
