/*
StringRedisTemplate:操作的是 string Value 也是string 的数据；
Redis 中的 value的类型是：string，list,set,zset,hash
RedisTemplate:key -- Object value --Object

            key    valule
        原本 string   string
        name ---->namexxx
        现在读的时候，会将键进行序列化，讲序列化后的值再取值redis 去找这个键，由于原本的name的值是字符串没有进行序列化，所以找不到，
        redisTemplate 默认是做JdkSerializationRedisSerializer
        如果查找的是一个字符串，将序列化方式变成自负床方式序列化；
