有人能帮我测试一下junit服务、控制器和存储库吗。在为服务和控制器类编写测试用例时，我遇到了很多错误。
这是我的服务班

import com.controller.ValidatorClass;
import com.model.Entity;
import com.model.Status;
import com.repository.Repository;

@Service
public class Service {

    @Autowired
    private Repository repository;

    @Autowired
    private SequenceGeneratorService service;

    public ResponseEntity storeInDb(ExecutorEntity model) {
        ValidatorClass validation = new ValidatorClass();
        Map<String, String> objValidate = validation.getInput(model.getLink(), model.getUsername(), 
                model.getPassword(), model.getSolution());
        model.setId(service.getSequenceNumber(Entity.SEQUENCE_NAME));
        model.setStatus(Status.READY);
        repository.save(model);
        return new ResponseEntity(model, HttpStatus.OK);
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public List<String> handleValidationExceptions(MethodArgumentNotValidException ex) {
        return ex.getBindingResult()
            .getAllErrors().stream()
            .map(ObjectError::getDefaultMessage)
            .collect(Collectors.toList());
    }
}

这是我的控制器类

@RestController
@RequestMapping(value = "/create")
public class Controller {

    @Autowired
    private Service service;

    @RequestMapping(value = "/create", method = RequestMethod.POST)
    public ResponseEntity code(@Valid @RequestBody Entity model) {
        return service.storeInDb(model);
    }

我的模型课

@Transient  
    public static final String SEQUENCE_NAME = "user_sequence";

    @NotNull(message = "Name can not be Null")
    private String username;

    @NotNull(message = "Password can not be Null")
    private String password;

    @NotNull(message = "Jenkins Link can not be Null")
    private String Link;

    @NotNull(message = "Solution can not be Null")
    private String solution;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    private Status status; //enum class having READY and FAIL as values.

还有那些能手和二传手。
