java - 如何通过邮递员发送日期并将其保存到数据库中？

问题描述

我想通过 Postman 发出请求，并通过下面的方法接受它。据我了解，由于我错误地处理了日期，会弹出一个错误。问题：如何通过邮递员发送日期并将其正确保存在数据库中？

登录 IDEA 和 Postman：

   Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize value of type `java.time.LocalDate` from String "23/02/2020": Failed to deserialize java.time.LocalDate: (java.time.format.DateTimeParseException) Text '23/02/2020' could not be parsed at index 0; nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.time.LocalDate` from String "23/02/2020": Failed to deserialize java.time.LocalDate: (java.time.format.DateTimeParseException) Text '23/02/2020' could not be parsed at index 0
 at [Source: (PushbackInputStream); line: 2, column: 20] (through reference chain: task.homerent.model.Contract["start_date"])]

询问：

{
    "start_date" : "23/02/2020",
    "end_date" : "27/02/2020",
    "id_house" : 2,
    "id_tenant" : 2
}

代码：

@PostMapping("/rent")
    @PreAuthorize("hasAuthority('user:write')")
    public void homeRent(@RequestBody House house) {
        System.out.println("ID арендатора");
        System.out.println(house.getId_tenant());
        System.out.println("Начало аренды");
        int dates = Integer.valueOf(String.valueOf(house.getStart_date()));
        LocalDate date = new LocalDate(dates); - an error is displayed LocalDate(int, int, int) has private access in 'java.time.LocalDate'`
        System.out.println(date);
    }

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;
}

解决方案

您需要使用LocalDate.of(int,int,int)来构造一个 LocalDate 实例
