Я новичок в Spring Boot / JPA.Я пытаюсь выполнить операцию CRUD для модели такси.
Я получаю следующую ошибку:
com.microsoft.sqlserver.jdbc.SQLServerException: Неверное имя столбца 'taxi_id'
Любая помощь будет принята с благодарностью.
Это мой код хранилища:
package com.example.SpringBoot.Model.Repository;
import org.springframework.data.repository.CrudRepository;
import com.example.SpringBoot.Model.Taxi;
public interface DAO extends CrudRepository<Taxi, Integer>{
}
Контроллер
package com.example.SpringBoot.Controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.example.SpringBoot.Model.Taxi;
import com.example.SpringBoot.Model.Repository.DAO;
@RestController
public class TaxiController {
@Autowired
public DAO repo;
@PutMapping(path= "/Taxi" , produces = {"application/json"})
public Taxi insertTaxi(Taxi taxi) {
repo.save(taxi);
return taxi;
}
@DeleteMapping(path ="/Taxi/{TaxiId}")
public void deleteTaxi(@RequestParam int TaxiId) {
repo.deleteById(TaxiId);
}
@GetMapping(path ="/Taxi")
public List<Taxi> displayTaxi() {
return (List<Taxi>) repo.findAll();
}
}
Класс модели
package com.example.SpringBoot.Model;
import java.math.BigDecimal;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class Taxi {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int TaxiId;
private String TaxiType;
public int getTaxiId() {
return TaxiId;
}
public void setTaxiId(int taxiId) {
TaxiId = taxiId;
}
public String getTaxiType() {
return TaxiType;
}
public void setTaxiType(String taxiType) {
TaxiType = taxiType;
}
}
