如何在Cucumber step实现中@Autowire一个REST服务类(Spring boot)？

@RestController
@RequestMapping("/api")
public class MyRestController {
    @Autowired
    private MyService myService;

    @GetMapping("/data")
    public String getData() {
        return myService.getData();
    }
}

@RunWith(Cucumber.class)
@ContextConfiguration(classes = {MyRestController.class, MyStepDefinitions.class})
public class MyStepDefinitions {
    @Autowired
    private MyRestController myRestController;

    // Step definitions...
}

            <name>json</name>
        </plugin>
    </plugins>
</cucumber-jvm-parallel-plugin>

@Given("I have a REST service")
public void iHaveARestService() {
    // Call REST service method
    String data = myRestController.getData();
    // Assertion or further steps...
}
