3、添加模板

2、使用

1、导入maven依赖

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.28</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>tea-openapi</artifactId>
            <version>0.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>dysmsapi20170525</artifactId>
            <version>2.0.9</version>
        </dependency>

2、创建工具类，用于随机生成验证码RandomUtil.java

package com.tuzhi.service_msm.util;

import java.text.DecimalFormat;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Random;

/**
 * 获取随机数
 * 
 * @author qianyi
 *
 */
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;
   }
}

2、创建service业务类MsmServiceImpl.java

package com.tuzhi.service_msm.service.impl;

import com.alibaba.fastjson.JSONObject;
import com.aliyun.dysmsapi20170525.Client;
import com.aliyun.dysmsapi20170525.models.SendSmsRequest;
import com.aliyun.dysmsapi20170525.models.SendSmsResponse;
import com.aliyun.teaopenapi.models.Config;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;
import com.tuzhi.service_msm.service.MsmService;
import com.tuzhi.utilcommon.result.Result;
import com.tuzhi.utilcommon.result.ResultCode;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;

import java.util.Map;

@Service
public class MsmServiceImpl implements MsmService {

    //发送短信的方法
    @Override
    public boolean send(Map<String, Object> param, String phone){
        //配置文件
        Config config = new Config()
                .setAccessKeyId("LTAI5t8UDYKyZiH7fLespJrm")
                .setAccessKeySecret("oeQPbwJ8aWSyG9Q2sKtDifmZN0iIOU");
        config.endpoint = "dysmsapi.aliyuncs.com";
        try {
            //客户端
            Client client = new Client(config);

            SendSmsRequest request = new SendSmsRequest();
            request.setPhoneNumbers(phone);
            request.setSignName("阿里云短信测试");
            request.setTemplateCode("SMS_154950909");
            request.setTemplateParam(JSONObject.toJSONString(param));

            //发送
            client.sendSms(request);

        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }
}

3、创建控制层使用

@Autowired
private MsmService msmService;

@Autowired
private RedisTemplate<String,String> redisTemplate;

//发送短信的方法
@GetMapping("send/{phone}")
public Result sendMsm(@PathVariable String phone) {
    //1 从redis获取验证码，如果获取到直接返回
    String code = redisTemplate.opsForValue().get(phone);
    if(!StringUtils.isEmpty(code)) {
        return Result.ok();
    }
    //2 如果redis获取 不到，进行阿里云发送
    //生成随机值，传递阿里云进行发送
    code = RandomUtil.getFourBitRandom();
    Map<String,Object> param = new HashMap<>();
    param.put("code",code);
    //调用service发送短信的方法
    boolean isSend = msmService.send(param,phone);
    if(isSend) {
        //发送成功，把发送成功验证码放到redis里面
        //设置有效时间
        redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
        return Result.ok();
    } else {
        return Result.error().codeAndMessage(ResultCode.VALID_CODE_SEND_FAIL);
    }
}
     redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
        return Result.ok();
    } else {
        return Result.error().codeAndMessage(ResultCode.VALID_CODE_SEND_FAIL);
    }
}
