SpringBoot整合Redis时，使用LocalDate以下报错
org.springframework.data.redis.serializer.SerializationException: Could not read JSON: Cannot construct instance of `java.time.LocalDateTime`
(no Creators, like default constructor, exist): no String-argument constructor/factory method to deserialize from String value ('2021-03-06T11:27:13')
原因在于 localDateTime 无法完成反序列化，这里有2种解决方法。
1、直接在字段上面加两个注解即可
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)
private LocalDateTime createTime;
2、在 Redis 配置类加上如下代码。
