上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException

Question

我正在开发 spring 启动应用程序。在尝试了许多解决方案后，它没有得到 resolved.Please 帮助：

控制台： org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为 'doctorController' 的 bean 时出错：通过字段 'doctorService' 表示的不满足的依赖关系；嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为 'doctorService' 的 bean 时出错：通过字段 'doctorRepo' 表示的不满足的依赖关系；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为 'doctorRepository' 的 bean 时出错：调用 init 方法失败；嵌套异常是 org.springframework.data.mapping.PropertyReferenceException：未找到类型 Doctor 的属性 id！

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'doctorService': Unsatisfied dependency expressed through field 'doctorRepo';嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为 'doctorRepository' 的 bean 时出错：调用 init 方法失败；嵌套异常是 org.springframework.data.mapping.PropertyReferenceException：未找到类型 Doctor 的属性 id！

控制器：

@RestController
public class DoctorController {

    @Autowired
    private DoctorService doctorService;

    @RequestMapping("/hms/doctor")
    public List<Doctor> getAllDoctor()
    {
        return doctorService.getAllDoctor();
    }

    @RequestMapping(method=RequestMethod.POST,value="hms/doctor")
    public void addDoctor(@RequestBody Doctor doctor)
    {
        doctorService.addDoctor(doctor);

    }
}

服务class:

@Service
public class DoctorService {

    Logger logger= LoggerFactory.getLogger(DoctorService.class);

    @Autowired
    private DoctorRepository doctorRepo;

    public List<Doctor> getAllDoctor(){

        logger.error("error happened");
        logger.trace(" Error !!!");
        List<Doctor> doctor= new ArrayList<Doctor>();
        doctorRepo.findAll().forEach(doctor::add);      
        return doctor;

    }

    public Doctor getDoctorById(String doctorId) {
        return doctorRepo.findById(doctorId);       
    }

    public Doctor getDoctorByPhoneNumber(long phoneNumber)
    {
        return doctorRepo.findByPhoneNumber(phoneNumber);

    }


    public void addDoctor(Doctor doctor) {
        doctorRepo.save(doctor);                
    }

    public void updateDoctor(String doctorId,Doctor doctor) {
        doctorRepo.save(doctor);
    }
}

存储库：

public interface DoctorRepository extends CassandraRepository<Doctor, Integer>
{

    Doctor findById(String doctorId);

    Doctor findByPhoneNumber(long phoneNumber);

    void deleteById(String doctorId);

}

型号class:

@Entity
public class Doctor {

    @GeneratedValue(strategy=GenerationType.SEQUENCE)
    @PrimaryKey
    private int doctorId;
    private String doctorName;
    private long phoneNumber;
    private String specialization;
    private int totalExperience;
    private String workingDays[]= {"Mon","Tue","Wed","Thu","Fri","Sat","Sun"};

    public Doctor() {

    }

    public Doctor(int doctorId, String doctorName, long phoneNumber, String specialization, int totalExperience,
            String[] workingDays) {`enter code here`
        super();
        this.doctorId = doctorId;
        this.doctorName = doctorName;
        this.phoneNumber = phoneNumber;
        this.specialization = specialization;
        this.totalExperience = totalExperience;
        this.workingDays = workingDays;
// getters and setters

Answer 1

Doctor的Id是doctorId，所以

 Doctor findById(...
 void deleteById(...

应该是

Doctor findByDoctorId(...
void deleteByDoctorId(...

或将 doctorId 更改为简单的 id，使用 getter 和 setter。
