[英]How to send time value from Postman to my REST api
I have a class with a variable of type Date, representing a time我有一个带有 Date 类型变量的类,表示时间
@Entity
public class Product implements Serializable {
private static final long serialVersionUID = -7181205262894478929L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int productId;
@NotNull()
private String productName;
@Temporal(TemporalType.DATE)
@DateTimeFormat(style = "yyyy-MM-dd")
@NotNull()
private Date date;
@Temporal(TemporalType.TIME)
@DateTimeFormat(style = "hh:mm")
@NotNull()
private Date time;
....
}
Now I'm trying CRUD methods on Postman, and when I send现在我正在 Postman 上尝试 CRUD 方法,当我发送
{ "productName": "name", "date": "2016-03-10", "time": "10:29" }
{ "productName": "name", "date": "2016-03-10", "time": "10:29" }
I get我得到
400 Bad Request
400 错误请求
with a description:附有说明:
The request sent by the client was syntactically incorrect.
客户端发送的请求在语法上不正确。
When I try without time, it passes.当我没有时间尝试时,它就过去了。
If you are using Jackson, you can try the following solutions:如果您使用的是 Jackson,您可以尝试以下解决方案:
JsonDeserializer
JsonDeserializer
Define a custom JsonDeserializer
:定义一个自定义
JsonDeserializer
:
public class TimeDeserializer extends JsonDeserializer<Date> {
private SimpleDateFormat format = new SimpleDateFormat("hh:mm");
@Override
public Date deserialize(JsonParser p, DeserializationContext ctxt)
throws IOException, JsonProcessingException {
String date = p.getText();
try {
return format.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
}
Then just annotate your time
attribute with @JsonDeserialize
:然后只需使用
@JsonDeserialize
注释您的time
属性:
@NotNull
@Temporal(TemporalType.TIME)
@DateTimeFormat(style = "hh:mm")
@JsonDeserialize(using = TimeDeserializer.class)
private Date time;
@JsonFormat
annotation @JsonFormat
注解Alternativelly, you could try the @JsonFormat
annotation, instead of creating a custom JsonDeserializer
:或者,您可以尝试使用
@JsonFormat
注释,而不是创建自定义JsonDeserializer
:
@NotNull
@Temporal(TemporalType.TIME)
@DateTimeFormat(style = "hh:mm")
@JsonFormat(shape=JsonFormat.Shape.STRING, pattern="hh:mm")
private Date time;
Is hh:mm
the format you really want? hh:mm
是您真正想要的格式吗?
hh
means hours in 1-12 format while HH
means hours in 0-23 format . hh
表示1-12 格式的小时数,而HH
表示0-23 格式的小时数。 If you go for the 1-12 format, you could consider using the AM/PM marker : hh:mm a
.如果您选择 1-12 格式,您可以考虑使用AM/PM 标记:
hh:mm a
。
For more details, have a look at the SimpleDateFormat
documentation.有关更多详细信息,请查看
SimpleDateFormat
文档。
change this改变这个
@Temporal(TemporalType.TIME)
@DateTimeFormat(style = "hh:mm")
@NotNull()
private Date time;
instead of代替
@NotNull()
private String time;
because you try parse to String value 10:29
not a valid representation for your time
variable因为您尝试解析为字符串值
10:29
不是您的time
变量的有效表示
