I am printing date values in console it it is printing like this .Here I am getting time is wrong, I suppose to get time 07:30:04but I am getting 13:00:04except this everything is fine
我正在控制台中打印日期值,它是这样打印的。在这里我得到的时间是错误的,我想得到时间07:30:04但我得到13:00:04除了这一切都很好
PickUpDateAndTime:Sat Jun 10 13:00:04 IST 2017,ReturnDateAndTime:Sat Jun 10 13:00:04 IST 2017
Please help me with this.
请帮我解决一下这个。

The @JsonFormat annotations have timeZone issues. Please check the link for more details on issue.Hymanson-data-bind issueOverriding the timezone in ObjectMapper didnt worked either. I have solved the problem by implementing custom Date Deserializer as below:
@JsonFormat 注释有 timeZone 问题。请查看链接以获取有关问题的更多详细信息。Hymanson-data-bind 问题覆盖 ObjectMapper 中的时区也不起作用。我通过实现自定义日期反序列化器解决了这个问题,如下所示:
@Component
public class CustomDateDeserializer extends StdDeserializer<Date> {
/**
*
*/
private static final long serialVersionUID = 1L;
private SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); // specify your specific timezone
public CustomDateDeserializer() {
this(null);
}
public CustomDateDeserializer(Class<?> vc) {
super(vc);
}
@Override
public Date deserialize(JsonParser jsonparser, DeserializationContext context)
throws IOException, JsonProcessingException {
String date = jsonparser.getText();
try {
return formatter.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
}
and then apply the deserializer on setter method of your bean properties.
然后在 bean 属性的 setter 方法上应用反序列化器。
@JsonDeserialize(using = CustomDateDeserializer.class)
public void setReturnDateTime(Date returnDateTime) {
this.returnDateTime = returnDateTime;
}
similarly you can implement your custom serializer for vice versa operation.
同样,您可以实现您的自定义序列化程序,反之亦然。

The Hymanson @JsonFormat
annotation has a specific timezone
attribute. If you specify the timezone you wish to use, you can fix this issue.
Hymanson@JsonFormat
注释有一个特定的timezone
属性。如果您指定要使用的时区,则可以解决此问题。
Example:
例子:
@JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss", timezone = "Europe/Madrid")
参考:http: //fasterxml.github.io/Hymanson-annotations/javadoc/2.1.0/com/fasterxml/Hymanson/annotation/JsonFormat.html

I had the same problem before, it's a time zone problem, so I convert my date to string before sending, you can use this function to convert date to string :
我以前遇到过同样的问题,这是一个时区问题,所以我在发送之前将日期转换为字符串,您可以使用此函数将日期转换为字符串:
public static String dateFormatString(Date date, String pattern) {
if (date != null) {
SimpleDateFormat formatter = new SimpleDateFormat(pattern);
return formatter.format(date);
}
return null;
}
for the pattern you can use : yyyy-MM-dd HH:mm:ss
对于您可以使用的模式:yyyy-MM-dd HH:mm:ss
回答by Issam EL-ATIF
It is a time zone issue. When you don't specify a timezone Hymanson consider that date is in UTC time and convert it to your default locale which is IST. As you can see 07:30:04 UTCis equivalent to 13:00:04 IST.
这是一个时区问题。当您不指定时区时,Hymanson 考虑该日期是 UTC 时间并将其转换为您的默认语言环境,即 IST。如您所见07:30:04 UTC相当于13:00:04 IST。
You can specify timezone in input json like this "pickUpDateTime":"2017-06-10T07:30:04.000+05:30"
hence IST=UTC+5:30
您可以像这样在输入 json 中指定时区,"pickUpDateTime":"2017-06-10T07:30:04.000+05:30"
因此 IST=UTC+5:30
