[alibaba/fastjson]0001-01-01T00:00:00"这种格式的时间返序列化报NumberFormatException

如果数据中有这样格式的时间数据，反序列化的时候框架会抛出NumberFormatException。简单看了一下源码好像是里面判断时间的时候有点问题

  if ("0000-00-00".equals(strVal)
                    || "0000-00-00T00:00:00".equalsIgnoreCase(strVal)
                    || "0001-01-01T00:00:00+08:00".equalsIgnoreCase(strVal)) {
                return null;
            }
 int index = strVal.lastIndexOf('|');
            if (index > 20) {
                String tzStr = strVal.substring(index + 1);
                TimeZone timeZone = TimeZone.getTimeZone(tzStr);
                if (!"GMT".equals(timeZone.getID())) {
                    String subStr = strVal.substring(0, index);
                    JSONScanner dateLexer = new JSONScanner(subStr);
                    try {
                        if (dateLexer.scanISO8601DateIfMatch(false)) {
                            Calendar calendar = dateLexer.getCalendar();

                            calendar.setTimeZone(timeZone);

                            if (clazz == Calendar.class) {
                                return (T) calendar;
                            }

                            return (T) calendar.getTime();
                        }
                    } finally {
                        dateLexer.close();
                    }
                }
            }

            // 2017-08-14 19:05:30.000|America/Los_Angeles
//            
            long longVal = Long.parseLong(strVal);
            return (T) new java.util.Date(longVal);

判断没有包含这种0001-01-01T00:00:00格式的特殊时间数据类型

1.2.60 未复现。

Omega-Ariston

现在发现还有下面这种格式的时间也无法被正确解析，使用的版本是1.2.61

{
    "Email": "zhangsan@163.com",
    "RegTime": "2019-09-30T08:04:53.0650089+08:00",
    "UserName": "张三"
}

由于我们项目里面存在和.net接口交互，并且.net项目使用的JSON.Net序列化数据，时间格式默认使用的默认格式。Java项目使用fastjson在解析这种接口返回的时间数据的时候也会出现类似的异常
