值不存储在数据库中

  • 772

如果我发送值，为什么我的 id_house 和 id_tenant 为空？日期已正确保存。我如何询问谁租了哪间公寓。很可能我以某种方式处理不正确，因为在实体中我将它们列为类。一般来说，我不明白到底与什么有关。

我接受价值观：

@PostMapping("/rent")
    @PreAuthorize("hasAuthority('user:write')")
    public void homeRent(@RequestBody Contract contract) {
        contractRepository.save(contract);
    }

合同：

@Data
@Entity
@Table(name = "contract", schema = "public")
public class Contract {
    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

@ManyToOne
@JoinColumn(name = "id_house")
@ToString.Exclude
@EqualsAndHashCode.Exclude
@JsonIgnore
private House house;

@ManyToOne
@JoinColumn(name = "id_tenant")
@EqualsAndHashCode.Exclude
@ToString.Exclude
@JsonIgnore
private User user;

@Column(name = "end_date")
private LocalDate end_date;
@Column(name = "start_date")
private LocalDate start_date;
}

通过邮递员请求：

{
    "start_date" : "2020-03-12",
    "end_date" : "2020-03-19",
    "id_house" : 2,
    "id_tenant" : 3
}

    问题很容易解决，需要保存类，这是我的实现：

    public class ContractDto {

    @NotNull
    @NotEmpty
    private LocalDate start_date;

    @NotNull
    @NotEmpty
    private LocalDate end_date;

    @NotNull
    @NotEmpty
    private Long id_house;

    @NotNull
    @NotEmpty
    private Long id_tenant;

    public LocalDate getStart_date() {
        return start_date;
    }

}

    如何保存的示例：

     @PostMapping("/rent")
 @PreAuthorize("hasAuthority('user:write')")
    public void homeRent(@RequestBody ContractDto contractDto) {
    House house = houseRepository.findById(contractDto.getId_house()).orElseThrow();
    User user = userRepository.findById(contractDto.getId_tenant()).orElseThrow();
    Contract contract = new Contract();
    contract.setHouse(house);
    contract.setUser(user);
    contract.setStart_date(contractDto.getStart_date());
    contract.setEnd_date(contractDto.getEnd_date());
    
    contractRepository.save(contract);
  }
