报错如下: 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) 查看后发现是数据从redis中取出时,Jackson2反序列化数据处理LocalDateTime类型时出错,原因是:J...

2. 分析可能导致“redis cannot deserialize”的原因 序列化与反序列化方法不匹配:如果存储数据时使用的序列化方法与读取数据时使用的反序列化方法不一致,就会导致反序列化失败。 Redis 配置问题:如果 Redis 的配置不正确,比如使用了错误的序列化器,也可能导致反序列化失败。 数据损坏:存储在 Redis 中的数据可能由于...

可以看出是sping对redis查询的返回结果进行deserialize的时候出错了 然异常的提示也很明确:序列号对象生成这个字节数组的方法是否与默认的反序列化方法相对应;应该就是对称性吧 , 你用A方法对B进行序列化然后用不对称的反序列化方法C进行反序列号 , 肯定会有问题 。 结果在国外大神的回复中找到了答案: by default...

redis Cannot deserialize 由于自己序列化了一次,然后redis中又配置了序列化的类,所以获取的时候编码不对,错误,这时不需要自己特意去实例化类后保存,直接用配置好的即可 <bean id="redisTemplate" class="org.springframework.data.redis.core.Str ...
