编码测试：
- 连接数据库
- 操作命令
- 断开连接
事务：

        Jedis jedis=new Jedis("127.0.0.1",6379);
        jedis.flushDB();
        Transaction multi =jedis.multi();
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("hello","world");
        jsonObject.put("name","zzh");
        String result = jsonObject.toJSONString();
        try {
            multi.watch("user1","user2"); //监控 user1和user2
            multi.set("user1", result);
            multi.set("user2", result);
            multi.exec();// 执行事务
        }catch (Exception e){
            e.printStackTrace();
            multi.discard();//放弃事务
        }finally {
            System.out.println(jedis.get("user1"));
            System.out.println(jedis.get("user2"));
            jedis.close();//关闭连接
        }
