第一次写短信服务，没想到一次就成功了，还是要谢谢同事给我提供的工具类吧，首先需要导入依赖

             
             
                 
      
       com.aliyun
                  
      
       aliyun-java-sdk-core
                  
      
       3.3.1
          
              
             
             
                 
      
       com.aliyun
                  
      
       aliyun-java-sdk-dysmsapi
                  
      
       1.1.0
              
     

然后就是工具类，一个是购买了短信服务的模板填写信息类，

public class GlobalConfigUtils {    /**     * 微信公众平台相关字段     */    public static final String WxAppId = "";    public static final String WxAppSecret = "";    /**     * 阿里云通信发送短信验证码相关     */    //必填:短信签名-可在短信控制台中找到    public static final String AliMsgSignName = "";    //必填:短信模板-可在短信控制台中找到    public static final String AliTemplateCode = "";    // 通知用户发快递的模板    public static final String AliNotichDeliveryTemplateCode = "";    public static final String AliAccessKeyId = "";    public static final String AliAccessKeySecret = "";}

另一个是短信发送的工具类，实现短信发送调用sendMsg(String phoneNumber, String code)就行。

public class AliyunSmsUtils {    //产品名称:云通信短信API产品,开发者无需替换    static final String product = "Dysmsapi";    //产品域名,开发者无需替换    static final String domain = "dysmsapi.aliyuncs.com";    //填写自己的appKey    static final String accessKeyId = GlobalConfigUtils.AliAccessKeyId;    static final String accessKeySecret = GlobalConfigUtils.AliAccessKeySecret;    /**     * 发送短信验证码     *     * @return     * @throws ClientException     * @throws ServerException     */    public static SendSmsResponse sendMsg(String phoneNumber, String code) throws ServerException, ClientException {        //可自助调整超时时间        System.setProperty("sun.net.client.defaultConnectTimeout", "10000");        System.setProperty("sun.net.client.defaultReadTimeout", "10000");        //初始化acsClient,暂不支持region化        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId, accessKeySecret);        DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", product, domain);        IAcsClient acsClient = new DefaultAcsClient(profile);        //组装请求对象-具体描述见控制台-文档部分内容        SendSmsRequest request = new SendSmsRequest();        //必填:待发送手机号        request.setPhoneNumbers(phoneNumber);        //必填:短信签名-可在短信控制台中找到        request.setSignName(GlobalConfigUtils.AliMsgSignName);        //必填:短信模板-可在短信控制台中找到        request.setTemplateCode(GlobalConfigUtils.AliTemplateCode);        //可选:模板中的变量替换JSON串,如模板内容为"亲爱的${name},您的验证码为${code}"时,此处的值为        request.setTemplateParam("{\"number\":" + "\"" + code + "\"}");        //选填-上行短信扩展码(无特殊需求用户请忽略此字段)        //request.setSmsUpExtendCode("90997");        //可选:outId为提供给业务方扩展字段,最终在短信回执消息中将此值带回给调用者//        request.setOutId("yourOutId");        //hint 此处可能会抛出异常，注意catch        SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request);        return sendSmsResponse;    }    public static SendSmsResponse sendMsg(Admin admin) throws ServerException, ClientException {        //可自助调整超时时间        System.setProperty("sun.net.client.defaultConnectTimeout", "10000");        System.setProperty("sun.net.client.defaultReadTimeout", "10000");        //初始化acsClient,暂不支持region化        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId, accessKeySecret);        DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", product, domain);        IAcsClient acsClient = new DefaultAcsClient(profile);        //组装请求对象-具体描述见控制台-文档部分内容        SendSmsRequest request = new SendSmsRequest();        //必填:待发送手机号        request.setPhoneNumbers(admin.getPhone());        //必填:短信签名-可在短信控制台中找到        request.setSignName(GlobalConfigUtils.AliMsgSignName);        //必填:短信模板-可在短信控制台中找到        request.setTemplateCode(GlobalConfigUtils.AliNotichDeliveryTemplateCode);        //可选:模板中的变量替换JSON串,如模板内容为"亲爱的${name},您的验证码为${code}"时,此处的值为        request.setTemplateParam("{\"name\":" + "\"" + admin.getNickname() + "\"}");        SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request);        return sendSmsResponse;    }}
