这是一个Redis存储token出现的问题,异常场景是这样的:

        我在Redis中以token为Key存入了登录用户的信息,每次请求都会被拦截校验,还会在一些特定的场景更改登录用户的信息并且以token覆盖Redis里面的数据,在一次覆盖以后抛出了异常

完整异常是这样的:

异常场景是以下一段代码,经过多次排查才发现了可以之处,尝试了一下修改出现问题的地方,发现问题就解决了,对Redis的认识并不多,大胆猜测这存储的时候因为我覆盖时候的对象不是同一个了,内存地址发生了变化,才会导致我出现的问题

public ResultModel openAnAccount(@RequestHeader("toKen") String toKen, @RequestBody         
            UserEntity userEntity) throws BusinessException{
        UserEntity user = getTokenUser(toKen);
        // 这一步是从Redis中获取到的用户信息

        }
        userEntity.setId(user.getId());
        userEntity.setIsIdentification(65);
        user.setIsIdentification(65);
        userService.openAnAccount(userEntity);
        Map<String, Object> map = new HashMap<>();
        map.put("openAnAccount", "开户成功, 您完成了实名");
        redisTemplate.opsForValue().set(toKen, userEntity, 30 * 24 * 60 * 60);
        // 问题就出在了这一步, 上面我从Redis中获取到的对象和我现在放入Redis中覆盖的对象不一样
        return new ResultModel().success(map);
    }

解决场景:把Redis的set方法里传的对象改成获取时候得到的对象问题即可解决;

        redisTemplate.opsForValue().set(toKen, user, 30 * 24 * 60 * 60);
        // 把这一步 覆盖Redis中的对象替换成前面从Redis中获取下来的对象

问题解决:希望可以得到我的猜测结果,或者有大佬帮我讲解一下Redis
