Spring Boot Postgres JPA，不返回主键以响应findAll（）

Question

员工班

@Entity
@Table(name = "employees")
public class Employee {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "eid", unique = true, nullable = false)
    private long eid;
    
    @Column(name ="first_name")
    private String firstName;
    
    @Column(name ="last_name")
    private String lastName;

    @Column(name ="email_id")
    private String emailId;
        
    
    public Employee() {
        
    }
    
    public Employee(String firstName, String lastName, String emailId) {
        super();
        this.firstName = firstName;
        this.lastName = lastName;
        this.emailId = emailId;
    }
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getEmailId() {
        return emailId;
    }
    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }   
}

员工回购

@Repository
public interface EmployeeRepo extends JpaRepository<Employee, Long>{
}

控制器类

@CrossOrigin(origins = {"http://localhost:3000/"})
@RestController
@RequestMapping("/api/v1/")
public class EmployeeController {

    @Autowired  //Creates object internally on runtime
    private EmployeeRepo employeeRepo;
    
    //get all employee
    @GetMapping("/employees")
    public List<Employee> getAllEmployees(){
        return employeeRepo.findAll();      
    }
}

应用属性

Springjpa。数据库平台=组织。冬眠地方话PostgreSql方言

Springjpa。显示sql=true

spring.jpa.properties.hibernate.format_sql=true

spring.jpa.hibernate.ddl自动更新

当我向/api/v1/employees发送get请求时，我得到的响应是

[{“firstName”：“aa”，“lastName”：“bb”，“emailId”：”[e-mail]" } ]

我希望是[{“eid”：1，“firstName”：“aa”，“lastName”：“bb”，“emailId”：”[e-mail]" } ]

Answer 1

我相信你需要一个员工类eid的getter。

将该方法添加到Employee类。

public long getEid() {
   return this.eid;
}
