创建名称为“出租车”的bean时出错

Question

当我试图运行我的项目时，我遇到了以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'taxeIRImpl': Unsatisfied dependency expressed through field 'taxeIRDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taxeIRDao' defined in com.example.taxe.dao.TaxeIRDao defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Invocation of init method failed; nested exception is org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract com.example.taxe.bean.TaxeIR com.example.taxe.dao.TaxeIRDao.findbyMoisAndAnneAndEmploye(int,int,com.example.taxe.bean.Employe)!

这是我的豆子：

@Entity
public class TaxeIR {
    @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private int mois;
    private int annee;
    @ManyToOne
    private Employe employe;
    @ManyToOne
    private Employeur employeur;
    private double salaire;
    private double cotisation;
    private String employeICE;
    @ManyToOne
    private User user;

@Entity
public class Employe {
    @Id @GeneratedValue (strategy = GenerationType.IDENTITY)
    private Long id;
    private String cin;
    private String nom;
    private String prenom;
    private double salaire;
    @ManyToOne
    private Employeur employeur;

@Repository
public interface TaxeIRDao extends JpaRepository<TaxeIR, Long> {
    TaxeIR findbyMoisAndAnneAndEmploye(int mois,int annee,Employe employe);
    List<TaxeIR> findByEmployeCin(String cin);
    List<TaxeIR> findByUserLogin(String login);
    List<TaxeIR> findByEmployeICE(String rc);
}

@Service
public class TaxeIRImpl implements TaxeIRService {
    @Autowired
    TaxeIRDao taxeIRDao;

    @Override
    public List<TaxeIR> findByEmployeCin(String cin) {
        return findByEmployeCin(cin);}

    @Override
    public List<TaxeIR> findByUserLogin(String login) {
        return findByUserLogin(login);}

    @Override
    public TaxeIR findbyMoisAndAnneAndEmploye(int mois, int annee, Employe employe) {
        return findbyMoisAndAnneAndEmploye(mois,annee,employe);}

    @Override
    public List<TaxeIR> findByEmployeICE(String rc) {
        return taxeIRDao.findByEmployeICE(rc);}
    @Override
    public int save(TaxeIR taxeIR) {
        TaxeIR taxeIRfound = findbyMoisAndAnneAndEmploye(taxeIR.getMois(),taxeIR.getAnnee(),taxeIR.getEmploye());
        if(taxeIRfound!=null)
            return -1;
        else {
            taxeIRDao.save(taxeIR);
            return 1;
        }
    }
}

@RestController
@RequestMapping("/api/v1/taxeIR")
public class TaxeIRWs {
    @Autowired
    private TaxeIRImpl taxeIRImpl;
    @GetMapping("/cin/{cin}")
    public List<TaxeIR> findByEmployeCin(@PathVariable String cin) {
        return taxeIRImpl.findByEmployeCin(cin);
    }
    @GetMapping("/login/{login}")
    public List<TaxeIR> findByUserLogin(@PathVariable String login) {
        return taxeIRImpl.findByUserLogin(login);
    }
    @GetMapping("/mois/{mois}/annee/{annee}")
    public TaxeIR findbyMoisAndAnneAndEmploye(@PathVariable int mois,@PathVariable int annee,@RequestBody  Employe employe) {
        return taxeIRImpl.findbyMoisAndAnneAndEmploye(mois, annee, employe);
    }

    @GetMapping("/rc/{rc}")
    public List<TaxeIR> findByEmployeICE(@PathVariable String rc) {
        return taxeIRImpl.findByEmployeICE(rc);
    }
    @PostMapping("/")
    public int save(@RequestBody TaxeIR TaxeIR) {
        return taxeIRImpl.save(TaxeIR);
    }
}

我查看了我所有的文件，我自己似乎找不到错误，就像我在标题中所说的，我是初学者，我需要一些帮助。

预期的结果是让它运行，让我能够通过邮递员与它互动

Answer 1

这是一个愚蠢的小错误，但魔鬼在细节上。

此方法需要使用CamelCase：

TaxeIR findbyMoisAndAnneAndEmploye(int mois,int annee,Employe employe);

你有“findby”，它必须是“findby”。首都B。
