Jedis操作hash和Jedis操作list

Jedis操作hash

/**
 * hash
 */
@Test
public void test3(){
    //1.获取连接
    Jedis jedis = new Jedis();//如果使用空参构造，默认值"localhost",6379端口
    //存储hash
    jedis.hset("user","name","lisi");
    jedis.hset("user","age","23");
    jedis.hset("user","gender","male");
    //获取hash
    String name = jedis.hget("user", "name");
    System.out.println(name);
    //获取hash所有map中的数据
    Map<String, String> user = jedis.hgetAll("user");
    Set<String> keySet = user.keySet();
    for (String key : keySet) {
        //获取value
        String value = user.get(key);
        System.out.println(key+":"+value);
    }

    //关闭连接
    jedis.close();
}

Jedis操作list

    /**
     * list
     */
    @Test
    public void test4(){
        //1.获取连接
        Jedis jedis = new Jedis();//如果使用空参构造，默认值"localhost",6379端口
        //存储list
        jedis.lpush("mylist","a","b","c");//从左边存
        jedis.rpush("mylist","a","b","c");//从右边存
        //list 范围获取
        List<String> mylist = jedis.lrange("mylist", 0, -1);
        System.out.println(mylist);
        //弹出
        String element1 = jedis.lpop("mylist");
        System.out.println(element1);

        String element2 = jedis.rpop("mylist");
        System.out.println(element2);

        //list 范围获取
        List<String> mylist2 = jedis.lrange("mylist", 0, -1);
        System.out.println(mylist2);
        //关闭连接
        jedis.close();
    }
