Jackson 将日期从 Twitter 反序列化为“ZonedDateTime”

Question

我想将日期从 Twitter 反序列化为ZonedDateTime. 我的程序在created_at反序列化领域失败。

我的域类

@JsonIgnoreProperties(ignoreUnknown = true)

public final class Tweet {

    public final String id;

    public final String idStr;

    public final ZonedDateTime created_at;

    public final String text;

    public final long timestamp_ms;

    public final User user;

    @JsonCreator

    public Tweet(@JsonProperty("id") String id,

                 @JsonProperty("id_str") String idStr,

                 @JsonProperty("created_at") ZonedDateTime created_at,

                 @JsonProperty("text") String text,

                 @JsonProperty("timestamp_ms") long timestamp_ms,

                 @JsonProperty("user") User user) {

        this.id = id;

        this.idStr = idStr;

        this.created_at = created_at;

        this.text = text;

        this.timestamp_ms = timestamp_ms;

        this.user = user;

    }

}

我的解析方法

public class TweetTest {

    @Test

    public void jackson_parsesDateTime() throws IOException {

        DateFormat dateFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy", Locale.ENGLISH);

        ObjectMapper mapper = new ObjectMapper();

        mapper.registerModule(new JavaTimeModule());

        mapper.setDateFormat(dateFormat);

        Tweet tweet = mapper.readValue(TWEET, Tweet.class);

        Assert.assertNotNull(tweet);

    }

    @Test

    public void ztd_parse() throws ParseException {

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss Z yyyy");

        ZonedDateTime.parse("Mon Aug 20 13:28:07 +0000 2018", formatter);

    }

}
