一、邮箱验证码
1、随机生成验证码工具类
/*** 随机生成验证码工具类*/
public class ValidateCodeUtils {/*** 随机生成验证码* @param length 长度为4位或者6位* @return*/public static Integer generateValidateCode(int length){Integer code =null;if(length == 4){code = new Random().nextInt(9999);//生成随机数，最大为9999if(code < 1000){code = code + 1000;//保证随机数为4位数字}}else if(length == 6){code = new Random().nextInt(999999);//生成随机数，最大为999999if(code < 100000){code = code + 100000;//保证随机数为6位数字}}else{throw new RuntimeException("只能生成4位或6位数字验证码");}return code;}/*** 随机生成指定长度字符串验证码* @param length 长度* @return*/public static String generateValidateCode4String(int length){Random rdm = new Random();String hash1 = Integer.toHexString(rdm.nextInt());String capstr = hash1.substring(0, length);return capstr;}
}
2、邮箱配置
@Component
@Configuration
public class MailConfig {@Resourceprivate MailProperties mailProperties;public String getFrom() {return mailProperties.getFrom();}public JavaMailSender getMailSender(String username, String password) {JavaMailSenderImpl mailSender = new JavaMailSenderImpl();mailSender.setHost(mailProperties.getHost());mailSender.setPort(mailProperties.getPort());// 如果没有自定义的用户，就使用配置类里面的用户mailSender.setUsername(StringUtils.defaultString(username, mailProperties.getUsername()));mailSender.setPassword(StringUtils.defaultString(password, mailProperties.getPassword()));Properties props = mailSender.getJavaMailProperties();// starttls.enable = true 时为 smtpsprops.put("mail.transport.protocol", "smtps");props.put("mail.smtp.auth", mailProperties.getAuth());props.put("mail.smtp.starttls.enable", mailProperties.getStarttlsEnable());props.put("mail.smtp.ssl.trust", mailProperties.getSslTrust());props.put("mail.debug", "true");return mailSender;}
}
3、发送验证码
public void email(String email) {SimpleMailMessage message = new SimpleMailMessage();//接收者//邮件发送人message.setFrom(mailConfig.getFrom());// 邮件接收人（可以使用 String[] 发送给多个用户）if (StringUtils.isEmpty(email)){throw new ServiceException("指定接收者");}message.setTo(email);// 邮件标题message.setSubject("【phbbb】邮箱验证码");//随机生成6位验证码String code = ValidateCodeUtils.generateValidateCode(6).toString();System.out.println(code);//存储到redis 设置失效时间一分钟redisTemplate.opsForValue().set(CacheConstants.CAPTCHA_CODE_KEY + email,code,120, TimeUnit.SECONDS);// 邮件内容message.setText("修改用户资料的邮箱验证码为:" + code + "，验证码有效期为2分钟!");// 发送邮件mailConfig.getMailSender(null, null).send(message);}
二、短信发送验证码
1、短信发送工具类
/*** 短信发送工具类*/
@Component
public class SMSUtils {/*** 发送短信* @param signName 签名* @param templateCode 模板* @param phoneNumbers 手机号* @param param 参数*/private static final Logger log = LoggerFactory.getLogger(SMSUtils.class);@Value("${sms.accessKeyId}")private static String accessKeyId;@Value("${sms.secret}")private static String secret;@Value("${sms.signName}")private static String signName; // 短信签名@Value("${sms.templateCode}")private static String templateCode; //短信模板@Value("${sms.regionId}")private static String regionId; // 短信服务器区域public static void sendMessage(String phone,String code){DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId, secret);DefaultAcsClient client = new DefaultAcsClient(profile);CommonRequest request = new CommonRequest();request.setSysMethod(MethodType.POST);//下面两个不能动request.setSysProduct("Dysmsapi");request.setSysDomain("dysmsapi.aliyuncs.com");request.setSysVersion("2017-05-25");request.setSysAction("SendSms");//自定义参数(手机号,验证码,签名,模板)request.putQueryParameter("RegoinId", regionId);request.putQueryParameter("PhoneNumbers", phone);request.putQueryParameter("SignName", signName); //填自己申请的名称request.putQueryParameter("TemplateCode", templateCode);request.putQueryParameter("TemplateParam", "{\"code\":\"" + code + "\"}");try {CommonResponse response = client.getCommonResponse(request);boolean success = response.getHttpResponse().isSuccess();System.out.println(success + "短信发送成功");}catch (Exception e) {e.printStackTrace();}}
}
2、发送验证码
@ApiOperation("发送短信验证码")
@PostMapping("/sendSms")
public Result sendSms(String phone) {if(StringUtils.isNotEmpty(phone)){//生成随机的4位验证码String code = ValidateCodeUtils.generateValidateCode(4).toString();//调用阿里云提供的短信服务API完成发送短信SMSUtils.sendMessage(phone,code);//需要将生成的验证码保存到redis,设置失效时间五分钟redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);return success("手机验证码短信发送成功");}return error("短信发送失败");
}
