[英]spring.jackson.date-format property does not work properly for the date serialization with @Temporal annotation
I have the following property in application.properties file: 我在application.properties文件中有以下属性:
spring.jackson.date-format=yyyy-MMM-dd
There is object definition to be serialized: 有序列化的对象定义:
public class InjuryDTO {
private Long id;
private String kindOfInjury;
private String muscle;
private String side;
private Integer outOfTraining;
private Date injuryDate;
private Long athleteId;
// getters and setters are omitted for brevity }
This is class from which InjuryDTO object is originally created: 这是最初创建InjuryDTO对象的类:
@Entity
@Table(name = "INJURY")
public class Injury {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "INJURY_ID")
private Long id;
@Column(name = "KIND_OF_INJURY")
private String kindOfInjury;
@Column(name = "MUSCLE")
private String muscle;
@Column(name = "SIDE")
private String side;
@Column(name = "OUT_OF_TRAINING")
private Integer outOfTraining;
@Temporal(value = TemporalType.DATE)
@Column(name = "INJURY_DATE")
private Date injuryDate;
@ManyToOne
@JoinColumn(name = "ATHLETE_ID")
@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private Athlete athlete;
// get,set-ters are removed for brevity
}
So, if the deserialization of this JSON property happens: 因此,如果发生此JSON属性的反序列化:
"injuryDate":"2018-Jun-02"
Jackson accepts this string and transforms it to the corresponding java.util.Date object, but when serialization happens with no commented @Temporal(value = TemporalType.DATE)
annotation then server gets back the following JSON property: "injuryDate":"2018-06-02"
. Jackson接受此字符串并将其转换为相应的java.util.Date对象,但是当序列化发生时没有注释
@Temporal(value = TemporalType.DATE)
注释时,服务器将返回以下JSON属性: "injuryDate":"2018-06-02"
。
Question is : Why @Temporal annotation affects the actual representation of the date property in JSON? 问题是 :为什么@Temporal注释会影响JSON中date属性的实际表示?
Try this one: 试试这个:
@Temporal(TemporalType.DATE)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
@Column(name="INJURY_DATE")
private Date injuryDate;
