- 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
<!--aliyun--> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <version>4.5.1</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-dysmsapi</artifactId> <version>1.1.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.62</version> </dependency>
- 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”)
