SerializationException: Could not read JSON: Unrecognized field

org.springframework.data.redis.serializer.SerializationException: Could not read JSON: Unrecognized field

原因：对象中如果有setXXX或getXXX方法，或返回值为Boolean或boolean的isXXX方法，但没有对应的XXX字段，使用Jackson2JsonRedisSerializer序列化后json中会有对应的key值XXX，从而会导致反序列化失败。

解决办法：在类加上注解@JsonIgnoreProperties(ignoreUnknown = true)忽略实体中没有对应的json的key值，或者在set、get或is开头的方法上加上@JsonIgnore注解。

代码定位：（第一次序列化时调用，后续从缓存中取）
