嘗試在 Postman 上測驗我的 api 后，我收到此錯誤。
employeemanager 是一個 MySQL 資料庫。
這是我的模型
@Entity
@Table(name = "employee")
public class Employee implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(nullable = false, updatable = false)
private Long id;
private String name;
private String email;
private String jobTitle;
private String phone;
private String imageUrl;
@Column(nullable = false, updatable = false)
private String employeeCode;
public Employee() {
}
public Employee(Long id, String name, String email, String jobTitle, String phone, String imageUrl, String employeeCode) {
this.id = id;
this.name = name;
this.email = email;
this.jobTitle = jobTitle;
this.phone = phone;
this.imageUrl = imageUrl;
this.employeeCode = employeeCode;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {

}
public void setName(String name) {
this.name = name;
}
public String getEmail() {

}
public void setEmail(String email) {

}
public String getJobTitle() {

}
public String getEmployeeCode() {

}
public void setEmployeeCode(String employeeCode) {

}
@Override
public String toString() {
return getClass().getSimpleName() "("
"id = " id ", "
"name = " name ", "
"email = " email ", "
"jobTitle = " jobTitle ", "
"phone = " phone ", "
"imageUrl = " imageUrl ", "
"employeeCode = " employeeCode ")";
}
}
這是我的存盤庫
package com.example.employeemanager.repository;
import com.example.employeemanager.model.Employee;
import org.springframework.data.jpa.repository.JpaRepository;
import java.util.Optional;
public interface EmployeeRepo extends JpaRepository<Employee, Long> {
Optional<Employee> findEmployeeById(Long id);
void deleteEmployeeById(Long id);
}
這是我的服務
package com.example.employeemanager.service;

import com.example.employeemanager.model.Employee;
import com.example.employeemanager.repository.EmployeeRepo;

import java.util.UUID;
@Service
public class EmployeeService {
private final EmployeeRepo employeeRepo;
@Autowired
public EmployeeService(EmployeeRepo employeeRepo) {
this.employeeRepo = employeeRepo;
}
public Employee addEmployee(Employee employee) {
employee.setEmployeeCode(UUID.randomUUID().toString());
return employeeRepo.save(employee);
}
public List<Employee> findAllEmployees() {
return employeeRepo.findAll();
}
public Employee updateEmployee(Employee employee) {
return employeeRepo.save(employee);
}
public Employee findEmployeeById(Long id) {
return employeeRepo.findEmployeeById(id)
.orElseThrow(() ->new UserNotFoundException("User by id" id " was not found"));
}
public void deleteEmployee(Long id) {
employeeRepo.deleteEmployeeById(id);
}
}
這是 application.properties
