准备工作
开通短信服务(可参考博主的“手机短信验证码”)
如果开通不成功,就只能借下别人已经开通好的短信,如果不想重复,可在其下创建一个新的模板管理
这里只是介绍如何使用
导入依赖
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-core</artifactId>
<version>4.5.1</version>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-dysmsapi</artifactId>
<version>1.1.0</version>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.62</version>
发送验证码到手机上,验证码生成工具类(内容较为固定,也可根据需求改)
package com.xsha.msmservice.utils;
import java.text.DecimalFormat;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Random;
/**

*/
public class RandomUtil {
private static final Random random = new Random();
private static final DecimalFormat fourdf = new DecimalFormat("0000");
private static final DecimalFormat sixdf = new DecimalFormat("000000");
public static String getFourBitRandom() {
return fourdf.format(random.nextInt(10000));
}
public static String getSixBitRandom() {
return sixdf.format(random.nextInt(1000000));
}
/**
* 给定数组,抽取n个数据
* @param list
* @param n
* @return
*/
public static ArrayList getRandom(List list, int n) {
Random random = new Random();
HashMap<Object, Object> hashMap = new HashMap<Object, Object>();
// 生成随机数字并存入HashMap
for (int i = 0; i < list.size(); i++) {
int number = random.nextInt(100) + 1;
hashMap.put(number, i);
}
// 从HashMap导入数组
Object[] robjs = hashMap.values().toArray();
ArrayList r = new ArrayList();
// 遍历数组并打印数据
for (int i = 0; i < n; i++) {
r.add(list.get((int) robjs[i]));
System.out.print(list.get((int) robjs[i]) + "\t");
}
System.out.print("\n");
return r;
}
}
发送验证码,验证码是有有效时间的(时间可以自己设置)
这里可以创建常量类读取配置文件的阿里云密钥等信息(可参考博主的“对象存储”)

return true;
}
// 过期则生成随机验证码,并在发送之后向redis中存入手机号对应的验证码

try {
SendSmsResponse response = client.getAcsResponse(request);
// 发送短信,尽量打印出来是否发送成功
new Gson().toJson(response);
// 将验证码放置在redis缓存中,并设置5分钟有效时间,最后一个参数是单位
redisTemplate.opsForValue().set(phone, code, 5, TimeUnit.MINUTES);
} catch (ServerException e) {
e.printStackTrace();
return false;
} catch (ClientException e) {

return true;
