Spring在集成Redis时遇到键存在前缀错误的问题

    @Autowired
    RedisTemplate redisTemplate;
    
    User user=new User(5,"tomhs","tttt");
        ValueOperations opsForValue = redisTemplate.opsForValue();
        //存放key,
        opsForValue.set("user"+user.getId(),user);
    
        //读取数据;
        System.out.println(opsForValue.get("user" + user.getId()));
