Most likely your ReactJs app and Spring Boot app are running under different ports and you did not configure CORS in the Spring Rest mapped methods in order enable incoming requests from the host:port on which ReactJs is running:

@CrossOrigin(origins = "http://localhost:4200")
@GetMapping("/user")
public Greeting getUser(){}

You can also define it on the Controller itself:

@CrossOrigin(origins = "http://localhost:4200")
@RestController

You can also register a separate CORS filter for entire application: reference
