我清楚如果不涉及到跨时区，用LocalDateTime会更容易，但是现有系统设计时就用了ZonedDateTime
public class VO{
@JSONField(format="yyyy-MM-dd HH:mm:ss")
private ZonedDateTime modifyTime=ZonedDateTime .now();
//...getter/setter
}
System.err.println(JSON.toJSONString(new VO())); //{"modifyTime": "2017-01-04 13:21:39"} 输出的是东八区，也就是按照@JSONField输出本地时区的日期时间但是反序列化就不行了
JSON.parseObject("{'modifyTime': '2017-01-04 13:21:39'}", VO.class);

在Jdk8DateCodec中只对LocalDateTime进行了特殊处理，ZonedDateTime仅仅是ZonedDateTime.parse(text);
需要传入 类似 2017-01-04T13:21:39.005+08:00[Asia/Shanghai] 格式的才行，否则统统异常
jackson可以注册一个全局的类型，进行处理
@Configuration
public class JacksonConfiguration {
public static final DateTimeFormatter ISO_FIXED_FORMAT =
DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").withZone(ZoneId.of("Asia/Shanghai"));
@Bean
public Jackson2ObjectMapperBuilderCustomizer jacksonCustomizer() {
ObjectMapper objectMapper=new ObjectMapper();
objectMapper.registerModule(new JavaTimeModule());
return jackson2ObjectMapperBuilder -> jackson2ObjectMapperBuilder.serializers(new ZonedDateTimeSerializer(ISO_FIXED_FORMAT));
}
}在FastJson中有 JSON.parseObject(input, clazz, config, features)方法进行处理，但是，
ParserConfig config=new ParserConfig();
config.getDerializers().put(ZonedDateTime.class, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").withZone(ZoneId.of("Asia/Shanghai")));会报错，因为，value是ObjectDeserializer类型的
