WRITE_DATES_WITH_ZONE_ID feature not working when applied on @JsonFormat annotation #83
Description
Copied over from FasterXML/jackson-databind#1175 as was assigned to wrong module.
Firstly thank you for a fantastic library :-) Just one small issue:-
I am using Jackson 2.7.3 and I would like to specify the date format pattern and whether or not to display timezone information on a per property basis. Therefore I have specified
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy hh:mm:ss", with = JsonFormat.Feature.WRITE_DATES_WITH_ZONE_ID)
on my date property - see example class below:-
private static class DummyClassWithDate {
@JsonProperty("name")
private String name;
@JsonProperty("age")
private int age;
@JsonProperty("date")
@JsonFormat
(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy hh:mm:ss Z", with = JsonFormat.Feature.WRITE_DATES_WITH_ZONE_ID)
private DateTime date;
public DummyClassWithDate() {
}
public DummyClassWithDate(String name, int age, DateTime date) {
this.name = name;
this.age = age;
this.date = date;
}
public String getName() {
return name;
}
public int getAge() {
return age;
}
public DateTime getDate() {
return date;
}
public void setName(String aName) {
name = aName;
}
public void setAge(int anAge) {
age = anAge;
}
public void setDate(DateTime aDate) {
date = aDate;
}
}
However, although the pattern is being used, the timezone is not being preserved when serialized. Here is a unit test which shows the problem:
private final DummyClassWithDate dummyClassWithDateIncludingTimezone = new DummyClassWithDate("Test", 50, new DateTime(2015, 11, 23, 22, 06, 39, DateTimeZone.forID("Asia/Krasnoyarsk")));
@Test
public void testJacksonAnnotatedPOJOWithDateWithTimezoneToJson() throws Exception {
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());
assertEquals("{\"name\":\"Test\",\"age\":50,\"date\":\"23-11-2015 10:06:39 +0800[Asia/Krasnoyarsk]\"}",mapper.writeValueAsString(dummyClassWithDateIncludingTimezone));
}
and the results of running the test:
junit.framework.ComparisonFailure:
Expected :{"name":"Test","age":50,"date":"23-11-2015 10:06:39 +0800[Asia/Krasnoyarsk]"}
Actual :{"name":"Test","age":50,"date":"23-11-2015 02:06:39 +0000"}
If I change my test to add in:
mapper.configure(SerializationFeature.WRITE_DATES_WITH_ZONE_ID, true);
this fixes the issue however this is applying the setting to dates on ALL classes and I really only want it applied to specific properties.
