如何使用杰克逊反序列化JS日期? [英] How to deserialize JS date using Jackson?
问题描述
2011-04-08T09:00:00 / p>
当我尝试反序列化这个日期时,它将时区改为印度标准时间(当时增加+5:30)。这是我反序列化日期的方式:
SimpleDateFormat dateFormat = new SimpleDateFormat(yyyy-MM-dd'THH :mm:ss);
getObjectMapper()。getDeserializationConfig()。setDateFormat(dateFormat);
这样做也不会改变时区。我仍然得到IST的日期:
SimpleDateFormat dateFormat = new SimpleDateFormat(yyyy-MM-dd'T'HH:mm :ss);
dateFormat.setTimeZone(TimeZone.getTimeZone(GMT));
getObjectMapper()。getDeserializationConfig()。setDateFormat(dateFormat);
如何以时区的方式反序列出日期呢? / p>
我发现了一个工作,但是我需要在整个项目中注释每个日期的设置器。有没有办法在创建ObjectMapper时指定格式?
这是我所做的:
public class CustomJsonDateDeserializer extends JsonDeserializer< Date>
{
@Override
public Date deserialize(JsonParser jsonparser,
DeserializationContext deserializationcontext)throws IOException,JsonProcessingException {
SimpleDateFormat format = new SimpleDateFormat(yyyy -MM-dd'T'HH:mm:ss);
String date = jsonparser.getText();
try {
return format.parse(date);
} catch(ParseException e){
throw new RuntimeException(e);
}
}
}
并注释每个Date字段的setter方法:
@JsonDeserialize(using = CustomJsonDateDeserializer.class)
I'm getting a date string from ExtJS in the format:
"2011-04-08T09:00:00"
when i try to deserialize this date, it changes the timezone to Indian Standard Time (adds +5:30 to the time) . This is how i'm deserializing the date:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat);
Doing this also doesn't change the timezone. I still get the date in IST:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
dateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat);
How do I deserialize the date in the way in which it is coming without the hassles of Timezone?
I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?
Here's what I did:
public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
@Override
public Date deserialize(JsonParser jsonparser,
DeserializationContext deserializationcontext) throws IOException, JsonProcessingException {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String date = jsonparser.getText();
try {
return format.parse(date);
} catch (ParseException e) {
throw new RuntimeException(e);
}
}
}
And annotated each Date field's setter method with this:
@JsonDeserialize(using = CustomJsonDateDeserializer.class)
