## 实现 ##

新建Junit方法HashTest，然后依次打开以下注释代码

@Test
         public void HashTest()
         {
             //Map<String,String> map = new HashMap<String,String>();
             //map.put("key1","value1");
             //map.put("key2","value2");
             //map.put("key3","value3");
             //添加名称为hash的hash元素
             //jedis.hmset("hash",map);
    
             //向名称为hash的hash中添加元素
             //jedis.hset("hash","key5","value5");
             //System.out.println("散列hash的所有键值对为："+jedis.hgetAll("hash"));
             //System.out.println("散列hash的所有键为："+jedis.hkeys("hash"));
             //System.out.println("散列hash的所有值为："+jedis.hvals("hash"));
             //System.out.println("将key6保存的值加上一个整数，如果keys不存在则添加key6:"+jedis.hincrBy("hash","key6",3));
             //System.out.println("删除一个或者多个键值对:"+jedis.hdel("hash","key2"));
             System.out.println("散列hash的键值对的个数为:"+jedis.hlen("hash"));
             System.out.println("判断hash中是否存在key2:"+jedis.hexists("hash","key2"));
         }
