**使用Jackson2JsonRedisSerializer序列化LocalDateTime类型数据到Redis取出报错问题**

**大概错误提示：**org.[springframework][].data.redis.serializer.SerializationException: Could not read JSON: Cannot construct instance of \`java.time.LocalDateTime\` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

原因：我在redis.config文件配置序列化时，使用Jackson2JsonRedisSerializer来序列化数据到数据库时存入的数据格式不对，应该是yyyy-MMMM-…格式。

**解决方法：**

**方法1：**手动序列化和反序列化数据

**方法2(推荐)** **：**改用阿里的[fastJson][]作为序列化工具 或者使用其他

例如GenericFastJsonRedisSerializer 或FastJsonRedisSerializer
