StringRedisTemplate常用方法:

   這里給大家一個鏈接，StringRedisTemplate常用方法都在里面我就不一一列出來了  https://blog.csdn.net/awhip9/article/details/71425041

stringRedisTemplate.opsForValue().set("test", "100",60*10,TimeUnit.SECONDS);//向redis里存入數據和設置緩存時間  

stringRedisTemplate.boundValueOps("test").increment(-1);//val做-1操作  

stringRedisTemplate.opsForValue().get("test")//根據key獲取緩存中的val  

stringRedisTemplate.boundValueOps("test").increment(1);//val +1  

stringRedisTemplate.getExpire("test")//根據key獲取過期時間  

stringRedisTemplate.getExpire("test",TimeUnit.SECONDS)//根據key獲取過期時間並換算成指定單位  

stringRedisTemplate.delete("test");//根據key刪除緩存  

stringRedisTemplate.hasKey("546545");//檢查key是否存在，返回boolean值  

stringRedisTemplate.opsForSet().add("red_123", "1","2","3");//向指定key中存放set集合  

stringRedisTemplate.expire("red_123",1000 , TimeUnit.MILLISECONDS);//設置過期時間  

stringRedisTemplate.opsForSet().isMember("red_123", "1")//根據key查看集合中是否存在指定數據  

stringRedisTemplate.opsForSet().members("red_123");//根據key獲取set集合  
 

 

RedisTemplate常用方法

     RedisTemplate中定義了對5種數據結構操作
      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
