需求：移动端输入手机号，获取验证码。点击登录，验证验证码是否输入错误、是否超时等情况，一旦校验通过，将用户数据保存到数据中（业务逻辑）。
前提：注册阿里用户，开通短信服务，申请key、秘钥、签名、短信模板。参考：
第一部分：准备工作
1、pom.xml文件添加阿里云短信服务的依赖
com.aliyun aliyun-java-sdk-core 4.0.6 com.aliyun aliyun-java-sdk-dysmsapi 1.1.0
此处可能会报错，官网也说了，好像这个版本的不是很稳定吧。异常可能是：
Java.lang.NoClassDefFoundError:com/aliyuncs/exceptions/ClientException
解决：
（1）方法一：检查lib文件下是否有aliyun-java-sdk-core包，没有的话就手动先添加上吧。
（2）方法二：将版本号改为3.3.1，即低版本
com.aliyun aliyun-java-sdk-core 3.3.1
2、下载官方demo，这个是发送短信的工具。

//hint 此处可能会抛出异常，注意catch QuerySendDetailsResponse querySendDetailsResponse = acsClient.getAcsResponse(request); return querySendDetailsResponse; } public static void main(String[] args) throws ClientException, InterruptedException { //发短信 SendSmsResponse response = sendSms(); System.out.println("短信接口返回的数据----------------"); System.out.println("Code=" + response.getCode()); System.out.println("Message=" + response.getMessage()); System.out.println("RequestId=" + response.getRequestId()); System.out.println("BizId=" + response.getBizId()); Thread.sleep(3000L); //查明细 if(response.getCode() != null && response.getCode().equals("OK")) { QuerySendDetailsResponse querySendDetailsResponse = querySendDetails(response.getBizId()); System.out.println("短信明细查询接口返回数据----------------"); System.out.println("Code=" + querySendDetailsResponse.getCode()); System.out.println("Message=" + querySendDetailsResponse.getMessage()); int i = 0; for(QuerySendDetailsResponse.SmsSendDetailDTO smsSendDetailDTO : querySendDetailsResponse.getSmsSendDetailDTOs()) { System.out.println("SmsSendDetailDTO["+i+"]:"); System.out.println("Content=" + smsSendDetailDTO.getContent()); System.out.println("ErrCode=" + smsSendDetailDTO.getErrCode()); System.out.println("OutId=" + smsSendDetailDTO.getOutId()); System.out.println("PhoneNum=" + smsSendDetailDTO.getPhoneNum()); System.out.println("ReceiveDate=" + smsSendDetailDTO.getReceiveDate()); System.out.println("SendDate=" + smsSendDetailDTO.getSendDate()); System.out.println("SendStatus=" + smsSendDetailDTO.getSendStatus()); System.out.println("Template=" + smsSendDetailDTO.getTemplateCode()); } System.out.println("TotalCount=" + querySendDetailsResponse.getTotalCount()); System.out.println("RequestId=" + querySendDetailsResponse.getRequestId()); } } } 第二部分：创建自己的MySessionContext
注意：由于移动端没有sessionId，我们需要自己传输sessionId获取session值。但出于安全性考虑，jdk现在去掉了通过sessionId获取session的方法。
解决：自建工具类，通过sessionId获取session。
1、创建一个MySessionContext.java类
public class MySessionContext { private static MySessionContext instance; private HashMap sessionMap; private MySessionContext() { sessionMap = new HashMap (); } public static MySessionContext getInstance() { if (instance == null) { instance = new MySessionContext(); } return instance; } public synchronized void addSession(HttpSession session) { if (session != null) { sessionMap.put(session.getId(), session); } } public synchronized void delSession(HttpSession session) { if (session != null) { sessionMap.remove(session.getId()); } } public synchronized HttpSession getSession(String sessionID) { if (sessionID == null) { return null; } return sessionMap.get(sessionID); } } 2、然后建立session监听，要实现HttpSessionListener接口
public class SessionListener implements HttpSessionListener { private MySessionContext myc = MySessionContext.getInstance(); public void sessionCreated(HttpSessionEvent httpSessionEvent) { HttpSession session = httpSessionEvent.getSession(); myc.addSession(session); } public void sessionDestroyed(HttpSessionEvent httpSessionEvent) { HttpSession session = httpSessionEvent.getSession(); myc.delSession(session); } } 3、接着，在web.xml中配置session监听器
com.chinapost.manager.utils.SessionListener

第三部分：实现业务
1、controller层
/** * app登录，附加：验证码时效性 * @param conditionStr * @return */ @RequestMapping(value = "/anLogin", method = RequestMethod.POST) @ResponseBody public ResponseModel anLogin(@RequestBody String conditionStr){ return androidLoginService.anLogin(conditionStr); } /** * 点击发送验证码 * @param conditionStr * @return */ @RequestMapping(value = "/getVerificationCode", method = RequestMethod.POST) @ResponseBody public ResponseModel getVerificationCode(@RequestBody String conditionStr) { return androidLoginService.getVerificationCode(conditionStr); } 2、service实现层
package com.test.service.androidService.impl;import com.alibaba.fastjson.JSON;import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;import com.test.dao.CarDriverMapper;import com.test.entity.business.CarDriver;import com.test.entity.common.
