SpringBoot整合阿里云短信服务

• 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>
  

• 编写配置文件

# 服务端口
server.port=8200
# 服务名称
spring.application.name=service-msg

# 返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

# redis配置
spring.redis.host=your_ip
spring.redis.port=6379
spring.redis.database=0
spring.redis.timeout=1800000
spring.redis.lettuce.pool.max-active=20
# 最大阻塞等待时间（负数表示没限制）
spring.redis.lettuce.pool.max-wait=-1
spring.redis.lettuce.pool.max-idle=5
spring.redis.lettuce.pool.min-idle=0

# aliyun 密钥及短信配置
aliyun.sms.accessKeyId=your_key
aliyun.sms.secret=your_secret
aliyun.sms.regionId=your_region_id
aliyun.sms.signName=your_sign_name
aliyun.sms.templateCode=your_template_code

• 编写一个常量类，读取配置文件

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class ConstantPropertiesUtils implements InitializingBean {
    @Value("${aliyun.sms.regionId}")
    private String regionId;
    @Value("${aliyun.sms.accessKeyId}")
    private String accessKeyId;
    @Value("${aliyun.sms.secret}")
    private String secret;
    @Value("${aliyun.sms.signName}")
    private String signName;
    @Value("${aliyun.sms.templateCode}")
    private String templateCode;

    public static String REGION_ID;
    public static String ACCESS_KEY;
    public static String ACCESS_SECRET;
    public static String SIGN_NAME;
    public static String TEMPLATE_CODE;

    @Override
    public void afterPropertiesSet() throws Exception {
        REGION_ID = this.regionId;
        ACCESS_KEY = this.accessKeyId;
        ACCESS_SECRET = this.secret;
        SIGN_NAME = this.signName;
        TEMPLATE_CODE = this.templateCode;        
    }
}

• 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”）

    package com.xsha.msmservice.service.impl;
    
    import com.alibaba.fastjson.JSONObject;
    import com.aliyuncs.DefaultAcsClient;

    import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest;
    import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;
    import com.aliyuncs.exceptions.ClientException;
    import com.aliyuncs.exceptions.ServerException;
    import com.aliyuncs.profile.DefaultProfile;
    import com.baomidou.mybatisplus.core.toolkit.StringUtils;
    import com.xsha.msmservice.service.MsmService;
    import com.xsha.msmservice.utils.RandomUtil;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.stereotype.Service;
    
    import java.util.HashMap;
    import java.util.Map;
    import java.util.concurrent.TimeUnit;
    
    @Service
    public class MsmServiceImpl implements MsmService {
    
        // 注入redis缓存对象
        @Autowired
        private RedisTemplate<String, String> redisTemplate;
    
        @Override
        public boolean sendMessage(String phone) {
            if(StringUtils.isEmpty(phone)) return false;
            // 先获取手机号对应的验证码（该验证码没过期）
            String code = redisTemplate.opsForValue().get(phone);
            if(!StringUtils.isEmpty(code)) {
                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
            code = RandomUtil.getFourBitRandom();
            Map<String, Object> map = new HashMap<>();
            map.put("code", code);
    
            // 设置短信配置
            DefaultProfile profile = DefaultProfile.getProfile(ConstantPropertiesUtils.REGION_ID, ConstantPropertiesUtils.ACCESS_KEY, ConstantPropertiesUtils.ACCESS_SECRET);
    
            IAcsClient client = new DefaultAcsClient(profile);
    
            SendSmsRequest request = new SendSmsRequest();
            request.setPhoneNumbers(phone);//接收短信的手机号码
            request.setSignName(ConstantPropertiesUtils.SING_NAME);//短信签名名称
            request.setTemplateCode(ConstantPropertiesUtils.TEMPLATE_CODE);//短信模板CODE
            request.setTemplateParam(JSONObject.toJSONString(map));//短信模板变量对应的实际值
    
            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) {
                e.printStackTrace();
                return false;
            }
            return true;
        }
    }
