短信技术

1.新建一个Springboot项目

2.导入依赖

<!--引入依赖-->
<dependency><groupId>com.aliyun</groupId><artifactId>aliyun-java-sdk-core</artifactId><version>4.5.3</version>
</dependency>
<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.75</version>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

3.创建Service、ServiceImpl、Controller

package com.dyt.service;import java.util.Map;public interface SendSms {public boolean send(String phoneNum, String TemplateCode, Map<String,Object> code);
}

package com.dyt.service.impl;import com.alibaba.fastjson.JSON;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.dyt.service.SendSms;
import org.springframework.stereotype.Service;import java.util.Map;@Service
public class SendSmsImpl implements SendSms {@Overridepublic boolean send(String phoneNum, String TemplateCode, Map<String, Object> code) {//连接阿里云DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "LTAI4FsqKCo7EFEejszonBYn", "密码");//构建一个客户端IAcsClient client = new DefaultAcsClient(profile);//构建一个请求CommonRequest request = new CommonRequest();request.setSysMethod(MethodType.POST);request.setSysDomain("dysmsapi.aliyuncs.com");request.setSysVersion("2017-05-25");//事件名称request.setSysAction("SendSms");//自定义参数（手机号、验证码、签名、模版）request.putQueryParameter("RegionId", "cn-hangzhou");request.putQueryParameter("PhoneNumbers", phoneNum);request.putQueryParameter("SignName", "DYT");request.putQueryParameter("TemplateCode", TemplateCode);request.putQueryParameter("TemplateParam", JSON.toJSONString(code));try {CommonResponse response = client.getCommonResponse(request);System.out.println(response.getData());return response.getHttpResponse().isSuccess();} catch (ServerException e) {e.printStackTrace();} catch (ClientException e) {e.printStackTrace();}return false;}
}

package com.dyt.controller;import com.aliyuncs.utils.StringUtils;
import com.dyt.service.SendSms;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.UUID;
import java.util.concurrent.TimeUnit;@RestController
@CrossOrigin //跨域支持
public class SendSmsApiController {@Autowiredprivate SendSms sendSms;@Autowiredprivate RedisTemplate<String,String> redisTemplate;@GetMapping("/send/{phone}")public String code(@PathVariable("phone")String phone){String code = redisTemplate.opsForValue().get(phone);if(!StringUtils.isEmpty(code)){return phone+":"+code+"已存在，还没有过期";}//生成验证码并存储到redis中code = UUID.randomUUID().toString().substring(0, 4);HashMap<String, Object> map = new HashMap<>();map.put("code", code);boolean isSend = sendSms.send(phone, "模版Code", map);if(isSend){redisTemplate.opsForValue().set(phone, code,5, TimeUnit.SECONDS);return phone+":"+code+"发送成功";}else{return "发送失败";}}
}

4.配置application.properties

server.port=9098spring.redis.host=127.0.0.1
spring.redis.port=6379

5.启动测试
