private static String dateFormat;
private static SerializeConfig mapping = new SerializeConfig();
static {
dateFormat = "yyyy-MM-dd HH:mm:ss";
mapping.put(Date.class, new SimpleDateFormatSerializer(dateFormat));
}
String jsonString = JSONObject.toJSONString(deal,mapping,SerializerFeature.WriteDateUseDateFormat);
这个方法是把jsonString放入redis中,但有两个方法同时放一个redis中,这两个方法的deal实体类中的属性还不相同,其他代码都一样,不知道是不是这个问题,希望有大神给解释一下

It seems that the thread of SimpleDateFormat is not safe, and multi-thread concurrency will cause this

It doesn’t feel necessary to be so complicated, it’s very simple to use fastjson
Map<String, Object> map = new HashMap<>();
map.put("createTime", new Date());
map.put("name", "simeon");
String jstr = JSON.toJSONStringWithDateFormat(map, "yyyy-MM-dd HH:mm:ss");
