分享一個完整的java發送短信驗證碼的完整實例，這是一個官方的使用demo，帶有60秒倒計時功能。效果:

我使用的是榛子云短信平臺, 官網地址:http://smsow.zhenzikj.com 我是java開發者，後端使用了springMvc，前端用的是jsp + jquery javascript

短信驗證碼實現流程 html

一、構造手機驗證碼，生成一個6位的隨機數字串；前端

二、使用接口向短信平臺發送手機號和驗證碼，而後短信平臺再把驗證碼發送到制定手機號上三、將手機號驗證碼、操做時間存入Session中，做爲後面驗證使用； java

四、接收用戶填寫的驗證碼、手機號及其餘註冊數據； jquery

五、對比提交的驗證碼與Session中的驗證碼是否一致，同時判斷提交動做是否在有效期內；六、驗證碼正確且在有效期內，請求經過，處理相應的業務。git

這裏省略了全部非空、手機號格式驗證spring

流程：

1)填寫手機號

2)獲取手機號碼，調用sendSms.html接口向手機發送短信驗證碼

3)用戶手機接收到驗證碼後，將其填寫到"驗證碼"文本框中

appId和appSecret換成你本身的，註冊以後可得到
