通过JsonSerialize快速转Long型转为日期字符型

public class JSONDateSerial extends JsonSerializer<Long> {
    public JSONDateSerial() {
    }

    public void serialize(Long aLong, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
        DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
        jsonGenerator.writeString(df.format(LocalDateTime.ofInstant(Instant.ofEpochMilli(aLong), ZoneId.of("Asia/Shanghai"))));
    }
}

    /**
     * 结束时间
     */
    @JsonSerialize(using= JSONDateSerial.class)
    private Long endDate;
