Jedis 操作各种redis中的数据结构

	@Test
    public void test2(){
        //获取链接
        Jedis jedis=new Jedis("localhost",6379);
        //存储
        jedis.set("username","zhangsan");
        //获取
        String username = jedis.get("username");
        System.out.println(username);
        //关闭链接
        jedis.close();
    }

可以使用setex()方法存储指定过期时间的key value
将activecode:hello键值对存入redis, 并且20秒后自动删除该键值对

jedis.setex("activecode",20,"hello");

	@Test
    public void test3() {
        //获取链接
        Jedis jedis = new Jedis("localhost", 6379);

        //存储hash
        jedis.hset("user", "name", "lisi");
        jedis.hset("user", "age", "23");
        jedis.hset("user", "gender", "male");

        //获取哈希
        String name = jedis.hget("user", "name");
        System.out.println(name);

        //获取hash的所有map中的数据
        Map user = jedis.hgetAll("user");

        //遍历集合
        Set keySet = user.keySet();
        for (String key : keySet) {
            //获取value
            String value = user.get(key);
            System.out.println(key + ":" + value);
        }
        //关闭链接
        jedis.close();
    }

	 @Test
    public void test4() {
        //获取链接
        Jedis jedis = new Jedis("localhost", 6379);

        //存储list
        jedis.lpush("mylist","a","b","c");//从做边存
        jedis.rpush("mylist","a","b","c");//从右边存

        //list范围获取
        List mylist = jedis.lrange("mylist", 0, -1);
        System.out.println(mylist);
        
        //关闭链接
        jedis.close();
    }

弹出操作

		//从左边弹出
        String element1 = jedis.lpop("mylist");
        System.out.println(element1);
        //从右边弹出
        String element2 = jedis.rpop("mylist");
        System.out.println(element2);

        //list范围获取
        List mylist2 = jedis.lrange("mylist", 0, -1);
        System.out.println(mylist2);

	@Test
    public void test5() {
        //获取链接
        Jedis jedis = new Jedis("localhost", 6379);

        //set存储
        jedis.sadd("myset","java","php","c++");

        //set获取
        Set myset = jedis.smembers("myset");
        System.out.println(myset);
        //遍历
        for (String s : myset) {
            System.out.println(s);
        }

        //关闭链接
        jedis.close();
    }

	@Test
    public void test6() {
        //获取链接
        Jedis jedis = new Jedis("localhost", 6379);

        //sortedset存储
        jedis.zadd("mysortedset",3,"孙悟空");
        jedis.zadd("mysortedset",2,"猪八戒");
        jedis.zadd("mysortedset",4,"二郎神");
        jedis.zadd("mysortedset",1,"沙悟净");

        //set获取
        Set mysortedset = jedis.zrange("mysortedset", 0, -1);
        System.out.println(mysortedset);

        //关闭链接
        jedis.close();
    }
