org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'ServiceBean:mistraServiceImpl:com.mistra.dubbo.api.MistraService:${mistra.service.version}' defined in null

@RestController
public class ConsumerController {

    @Reference(version = "${mistra.service.version}")
    private MistraService mistraService;

    @RequestMapping("/sayHello/{name}")
    public String sayHello(@PathVariable("name") String name) {
        return mistraService.welcome(name);
    }
}
