redis序列化LocalDateTime时报错：Could not read JSON: Cannot construct instance of `java.time.LocalDateTime`

在实体类中时间类型使用LocalDateTime时，存入redis中，取出时报错：

org.springframework.data.redis.serializer.SerializationException:
Could not read JSON: Cannot construct instance of java.time.LocalDateTime (no Creators, like default construct,exist):
no String-argument constructor/factory method to deserialize from String value (‘2019-11-13 18:05:32’)

解决方案：
LocalDateTime属性上加一下两个注解即可：

@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)
