FastJson输出时间类型强转为时间戳

下面以fastjson 1.2.56版本为例

      <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.56</version>
        </dependency>

在FastJsonConfig中配置 以LocalDateTime

.setSerializeFilters((ValueFilter) (o, s, source) -> {
            if (source == null) {
                return "";
            }
            if (source instanceof LocalDateTime) {
                return ((LocalDateTime) source).toInstant(ZoneOffset.of("+8")).toEpochMilli();
            }
            return source;
        });
