use this method to set timezone and replace @JsonFormat(pattern = “yyyy-MM-dd HH:mm:ss”, timezone=“GMT+8”)

(1)Model field

    @JSONField(format = DateTimeJsonFormatSerializer.TIME_FMT)//fastjson,JSON.toJSONString()@JsonSerialize(using = DateTimeJsonFormatSerializer.class)//jackson,影响http request@JsonDeserialize(using = DateTimeJsonFormatDeserializer.class)//jackson,影响http responseprivate Date deliverTime;
