Redis5种数据类型

• 字符串

   @GetMapping("/string")
    public String stringTest(){
        redisTemplate.opsForValue().set("str","Hello World");
        String str = (String)redisTemplate.opsForValue().get("str");
        return str;
    }

• 列表

@GetMapping("/list")
    public List<String> listTest(){
       ListOperations<String,String> listOperations= redisTemplate.opsForList();
       listOperations.leftPush("list","Hello");
       listOperations.leftPush("list","World");
       listOperations.leftPush("list","java");
      List<String> list = listOperations.range("list",0,2);
      return list;
    }

• 集合

@GetMapping("/set")
    public Set<String> setTest(){
     SetOperations<String,String> setOperations = redisTemplate.opsForSet();
     setOperations.add("set","Hello");
     setOperations.add("set","Hello");
     setOperations.add("set","Java");
     Set<String> set =setOperations.members("set");
     return set;
    }

• 有序集合

@GetMapping("/zset")
    public Set<String> zsetTest(){
        ZSetOperations<String,String> zSetOperations =   redisTemplate.opsForZSet();
        zSetOperations.add("zset","Hello",3);
        zSetOperations.add("zset","World",2);
        zSetOperations.add("zset","Python",1);
      Set<String> set =  zSetOperations.range("zset",0,2);
      return set;
    }

• 哈希

@GetMapping("/hashTest")
    public void hashTest(){
     HashOperations<String,String,String> hashOperations = redisTemplate.opsForHash();
     hashOperations.put("key","hashkey","hello");
        System.out.println(hashOperations.get("key","hashkey"));
    }
