（1）创建新模块service_msm
（2）创建配置文件
# 服务端口 server.port=8005 # 服务名 spring.application.name=service-msm # mysql数据库连接 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/guli?serverTimezone=GMT%2B8 spring.datasource.username=guli spring.datasource.password=123123 spring.redis.host=192.168.140.132 spring.redis.port=6379 spring.redis.database= 0 spring.redis.timeout=1800000 spring.redis.lettuce.pool.max-active=20 spring.redis.lettuce.pool.max-wait=-1 #最大阻塞等待时间(负数表示没限制) spring.redis.lettuce.pool.max-idle=5 spring.redis.lettuce.pool.min-idle=0 #最小空闲 #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 #配置mapper xml文件的路径 mybatis-plus.mapper-locations=classpath:com/atguigu/msmservice/mapper/xml/*.xml #mybatis日志 mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl（3）创建启动类
package com.atguigu.msmservice; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; import org.springframework.context.annotation.ComponentScan; @ComponentScan({"com.atguigu"}) @SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//取消数据源自动配置 public class ServiceMsmApplication { public static void main(String[] args) { SpringApplication.run(ServiceMsmApplication.class, args); } }（4）引入依赖
<dependencies> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> </dependency> </dependencies>（5）编写MsmApiController
@Api(description="短信发送管理") @RestController @RequestMapping("/edumsm/msm") @CrossOrigin public class MsmApiController { @Autowired private MsmService msmService; @Autowired private RedisTemplate<String,String> redisTemplate; @ApiOperation(value = "根据手机号发送验证码") @GetMapping("send/{phone}") public R sendMsmPhone(@PathVariable String phone){ //1 从redis里根据手机号获取数据 String rphone = redisTemplate.opsForValue().get(phone); //2 如果能取出数据直接返回 if(!StringUtils.isEmpty(rphone)){ return R.ok(); } //3 如果取不出数据，调接口发送短信 //3.1生成验证码，随机四位数 String code = RandomUtil.getFourBitRandom(); //3.2把生成的验证码封装到map Map<String,String> map = new HashMap<>(); map.put("code",code); //3.3调用service方法 boolean isSuccess = msmService.sendMsm(phone,map); //4 如果发送成功，把校验码往redis里存一份 if(isSuccess){ redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES); return R.ok(); }else { return R.error().message("发送短信失败"); } } }（6）编写MsmService接口
package com.atguigu.msmservice.service; import java.util.Map; public interface MsmService { public boolean send(String PhoneNumbers, String templateCode, Map<String, Object> param); }（7）实现MsmService接口
@Service public class MsmServiceImpl implements MsmService { //根据手机号发送验证码 @Override public boolean sendMsm(String phone, Map<String, String> map) { //0 判断手机号 if(StringUtils.isEmpty(phone)) return false; //1 创建初始化对象 DefaultProfile profile = DefaultProfile.getProfile("default", "LTAI3buexRAagkdy", "A6hpWJbF3Zz6wj3jxuBe40Mwryt1Zz"); IAcsClient client = new DefaultAcsClient(profile); //2 创建request对象 CommonRequest request = new CommonRequest(); //3 向request里设置参数 request.setMethod(MethodType.POST); request.setDomain("dysmsapi.aliyuncs.com"); request.setVersion("2017-05-25"); request.setAction("SendSms"); request.putQueryParameter("PhoneNumbers", phone); request.putQueryParameter("SignName", "我的谷粒在线教育网站"); request.putQueryParameter("TemplateCode", "SMS_183195440"); request.putQueryParameter("TemplateParam", JSONObject.toJSONString(map)); try { //4 调用初始化兑现方法实现发送 CommonResponse response = client.getCommonResponse(request); //5 通过response获取发送是否成功 boolean success = response.getHttpResponse().isSuccess(); return success; } catch (ClientException e) { e.printStackTrace(); return false; } } }
