JAVA實現發短信功能

相信這類型短信，大家收到的很多吧！但是，你知道這個是怎麼實現的嗎？肯定不是有人專門一個一個的發的，肯定是在程序裏批量執行的（這條短信肯定不止你一個人收到，當然，驗證碼肯定是你一個人收到的，但肯定不是人給你發的，肯定是程序給你發的）。

那麼，用程序該怎麼實現短信的發送功能呢？

首先我們需要短信發送的幾個jar包。

然後看代碼。

所以說，這個都實現了，像短信驗證碼啊，營銷短信啊，就只需要加邏輯控制，判斷，然後照樣調發送方法。好啦，今天就先寫到這。哎，我的視頻剪輯這段時間要擱淺了，總是計劃趕不上變化啊！學習是條不歸路啊！好像真的是找不到盡頭，發現不懂不明白的越來越多。
