【异常】LocalDateTime序列化问题：Cannot construct instance of `java.time.LocalDateTime`

错误信息：

Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDateTime` (no Creators, like default construct, exist): no String-argument constructor/factory method to deserialize from String value ('2019-12-16T11:28:00.246')

解决：LocalDateTime属性加上注解

@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)
private LocalDateTime localDateTime;
