Getting UnsatisfiedDependency exception(No qualifying bean of type found) even though bean is defined and using Service annotation

I am trying to run my basic restapi application which has some pojo defined and using service layer to fetch data from h2 database. But when i run the application, i am getting bean not found for one of the service object.

ProjectResController.java

    @RestController
@RequestMapping(ProjectRestController.ENDPOINT)

public class ProjectRestController {
public static final String ENDPOINT = "/api/v2/projects";

public static final String PATH_VARIABLE_ID = "id";
public static final String ENDPOINT_SYSTEM_ID = "/{systemId}/projects";
private static final String API_PARAM_ID = "ID";
@Autowired
private SdlcService sdlcService;
@Autowired
private ProjectService projectService;
@ApiOperation("Get a Project")
@GetMapping(ENDPOINT_ID)
public Project getProject(
@ApiParam(name = API_PARAM_ID, required = true) @PathVariable(PATH_VARIABLE_ID) final long projectId) {
return projectService.getProject(projectId);
}
@ApiOperation("Create a Project")
@PostMapping(ENDPOINT_SYSTEM_ID)
public Project createProject(@PathVariable(value = "systemId") Long systemId, @Valid @RequestBody Project project) {
sdlcService.findById(systemId).ifPresent(project::setSdlcSystem);
return projectService.saveProject(project);
}
}

Error

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Description:

Field sdlcService in com.restapi.restapi.Controller.ProjectRestController required a bean of type 'com.restapi.restapi.Service.SdlcService' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'com.restapi.restapi.Service.SdlcService' in your configuration.

You should annotate SdlcServiceImpl (and not it's interface) with @Service.

From @Service javadoc:
>Indicates that an annotated class is a "Service" (...)
>
>This annotation serves as a specialization of @Component, allowing for implementation classes to be autodetected through classpath scanning.
