StringRedisTemplate常用方法:


   这里给大家一个链接,StringRedisTemplate常用方法都在里面我就不一一列出来了  https://blog.csdn.net/awhip9/article/details/71425041



RedisTemplate常用方法


     RedisTemplate中定义了对5种数据结构操作
      redisTemplate.opsForValue();//操作字符串
      redisTemplate.opsForHash();//操作hash
      redisTemplate.opsForList();//操作list
      redisTemplate.opsForSet();//操作set
      redisTemplate.opsForZSet();//操作有序set





为人:谦逊、激情、博学、审问、慎思、明辨、 笃行
学问:纸上得来终觉浅,绝知此事要躬行
为事:工欲善其事,必先利其器。
态度:道阻且长,行则将至;行而不辍,未来可期
