[alibaba/fastjson]时间格式问题2018-05-21T14:39:44.9077913+08:00

9077913 这个值过大，不是毫秒数，这个是什么格式？

和第三方对接api时返回的时间格式，对方是用C#开发的。

目前的解决方法是使用LocalDateTime

@JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")
private LocalDateTime xxxDate;

但是这样也只能解析和S个数相同的时间

2018-05-21T14:39:44.9077913+08:00 解析成功
2018-05-21T14:39:44.907791+08:00 解析失败

第三方返回的S长度又不固定，比较难解决

我也遇到这个问题了，也是跟.net系统交互的时候，对方序列化过来的时间格式是： "2019-01-25T17:34:13.1920977+08:00" 这边fastjson反序列化失败

    static class Model{
        public Date date;
    }

    public static void main(String[] args) throws Exception {
        String json = "{\"date\":\"2019-01-25T17:34:13.1920977+08:00\"}";

        System.out.println("jackson:" + new ObjectMapper().readValue(json, Model.class).date);
        System.out.println("fastjson:" + JSON.parseObject(json, Model.class).date);
    }

@wenshao jackson（2.9.8）可以正确解析，fastjson（1.2.56）无法解析

最新版本 1.2.59，已经解决。

@JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")

1.2.59

@Data
public class LocalModel {

    @JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")
    private LocalDateTime localDateTime;

    @JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")
    private LocalDateTime localDateTime2;

    public static void main(String[] args) {
        String json = "{\n" +
                "\t\"localDateTime\":\"2018-05-21T14:39:44.9077913+08:00\"\n" +
                "}";
        LocalModel localModel = JSONObject.parseObject(json, LocalModel.class);
        System.out.println(JSON.toJSONString(localModel));
    }
}

报错

@Omega-Ariston

这是因为 java.time.LocalDateTime 不支持时区偏移量, 也就是 +08:00. 建议使用 java.time.OffsetDateTime

@lombok.Data
public class LocalModel {

    @com.alibaba.fastjson.annotation.JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")
    private java.time.OffsetDateTime localDateTime;

    @com.alibaba.fastjson.annotation.JSONField(format = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSXXX")
    private java.time.OffsetDateTime localDateTime2;

    public static void main(String[] args) {
        String json = "{\n" +
                "\t\"localDateTime\":\"2018-05-21T14:39:44.9077913+08:00\"\n" +
                "}";
        LocalModel localModel = com.alibaba.fastjson.JSONObject.parseObject(json, LocalModel.class);
        System.out.println(com.alibaba.fastjson.JSON.toJSONString(localModel));
    }
}
