本文为大家分享了SpringBoot使用邮箱发送验证码实现注册功能实例,供大家参考,具体内容如下
网站设计、成都网站制作的关注点不是能为您做些什么网站,而是怎么做网站,有没有做好网站,给创新互联一个展示的机会来证明自己,这并不会花费您太多时间,或许会给您带来新的灵感和惊喜。面向用户友好,注重用户体验,一切以用户为中心。
这里有两种方式:
使用Apache Common包中开源的email组件,通过实例化HtmlEmail()对象,可通过配置外置字典、或yml等配置文件实现灵活配置;
依赖:
org.apache.commons commons-email 1.5
使用SpringBoot Starter email组件;
依赖:
org.springframework.boot spring-boot-starter-mail
我这里是采用的第一种方式,简单易懂;
首先需要配置Email的各项参数,其中hostname、host、username、passsword(注意:此处的密码并不是登录的密码,而是邮箱开启smtp服务的令牌);
我这里使用SpringBoot的yml配置文件,可以通过切换不同的环境:local/dev/test/pro/prod等等环境实现灵活配置,该配置为自定义配置;
我此处使用的是本人的163邮箱,在实际开发中需要换为公司的或项目专用邮箱;
(注意:此种方式有缺陷,即为不能从外部进行灵活配置,只能写死配置文件,在实际使用上应该配置为数据字典,可以在外部直接进行灵活配置)
yml:
##Email配置 email: host-name: smtp.163.com #服务地址,可以直接在web端登录,找到smtp服务看到,163邮箱默认开放25端口,可暂时不设置 authentication: username: xxx.163.com password: xxx #手动的设置令牌 form: mail: xxx@163.com #发送方,必须为你设置的username一致 name: elog #发送方显示的名称,可以随意设置 charset: UTF-8 #编码格式,一般设置为UTF-8
util:
package com.hisw.rest.utils; import com.hisw.common.exception.RRException; import org.apache.commons.mail.HtmlEmail; /** * @ClassName EmailCodeUtils * @Description TODO 邮箱验证码工具类 * @Author liwenju * @Date 2019/5/15 14:20 * @Version 1.0 **/ public class EmailCodeUtils { /** * 生成6位随机验证码 * @return */ public static String getNumber(){ String str = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ"; String code = ""; for(int i= 0;i<6;i++){ int index = (int)(Math.random()*str.length()); code+=str.charAt(index); } return code; } /** * 发送邮箱验证码 * @param receiverEmail * @param subject * @param msg */ public static void sendEmailCode(String EMAIL_HOST_NAME,String EMAIL_FORM_MAIL, String EMAIL_FORM_NAME,String EMAIL_AUTHENTICATION_USERNAME, String EMAIL_AUTHENTICATION_PASSWORD,String receiverEmail, String subject,String msg){ try{ HtmlEmail email = new HtmlEmail(); email.setHostName(EMAIL_HOST_NAME); email.setCharset("utf-8"); email.setFrom(EMAIL_FORM_MAIL,EMAIL_FORM_NAME); email.setAuthentication(EMAIL_AUTHENTICATION_USERNAME,EMAIL_AUTHENTICATION_PASSWORD); email.addTo(receiverEmail); email.setSubject(subject); email.setMsg(msg); email.send(); }catch (Exception ex){ throw new Exception("发送验证码失败,原因:"+ex.getMessage()); } } }
注意:在静态工具类的方法中,不可直接调用@Value(value="$xxx")来获取yml的配置文件的参数值,否则会获取不到值。故不在该util类中直获取。如下所示:
/** * 获取邮箱配置 */ @Value(value = "${email.host-name}") public String EMAIL_HOST_NAME;
方法示例:
/** * 获取邮箱配置 */ @Value(value = "${email.host-name}") public String EMAIL_HOST_NAME; @Value(value = "${email.authentication.username}") public String EMAIL_AUTHENTICATION_USERNAME; @Value(value = "${email.authentication.password}") public String EMAIL_AUTHENTICATION_PASSWORD; @Value(value = "${email.charset}") public String EMAIL_CHARSET; @Value(value = "${email.form.mail}") public String EMAIL_FORM_MAIL; @Value(value = "${email.form.name}") public String EMAIL_FORM_NAME; @Autowired private SysUserDao sysUserDao; @Autowired private SysUserTokenDao sysUserTokenDao; @Autowired private redisUtils redisUtils; private Logger logger = LoggerFactory.getLogger(LoginUserServiceImpl.class); /** * 验证码过期时间60s */ private Integer redisExpire = 60 * 1000; /*** * 根据邮箱验证用户 * @param account * @return */ public SysUserEntity queryByEmail(String account){ SysUserEntity sysUserEntity = new SysUserEntity(); sysUserEntity.setEmail(account); return sysUserDao.selectOne(sysUserEntity); } /** * 判断该邮箱是否已存在 * @param email * @return */ public Boolean checkEmail(String email){ //首先判断该用户是否已存在 if (StringUtils.isNotEmpty(email)){ EntityWrapperuserEntityWrapper = new EntityWrapper<>(); userEntityWrapper.eq("email",email); List sysUserList = sysUserDao.selectList(userEntityWrapper); //如果已存在该用户 return sysUserList.size() <= 0; } return true; } /** *发送邮箱验证码 * */ public R sendRegisterEmailCode(String email) { try { //验证邮箱规则 if (!RegexUtils.checkEmail(email)){ throw new RRException("The mailbox does not conform to the specification!"); } if (!checkEmail(email)){ throw new RRException("This mailbox already exists. Please change the user's email and try again!"); } String emailCode = EmailCodeUtils.getNumber(); //发送验证码 EmailCodeUtils.sendEmailCode(EMAIL_HOST_NAME, EMAIL_FORM_MAIL, EMAIL_FORM_NAME, EMAIL_AUTHENTICATION_USERNAME, EMAIL_AUTHENTICATION_PASSWORD, email, EmailTextTemplate.REGISTER_SUBJECT, EmailTextTemplate.REGISTER_CONTENT + emailCode + EmailTextTemplate.CONTENT_SUFFIX); logger.info("验证码发送成功:{}", email); //发送成功,将该验证码按照规定格式放入redis redisUtils.set(RestRedisConstant.REST_ELOG_REGISTER_EMAIL_CODE_KEY + email, emailCode, redisExpire); logger.info("Redis存储验证码成功:{}", emailCode); return R.ok("The verification code has been sent to your mailbox and is valid for 60 seconds."); } catch (Exception ex) { return R.error(ex.getMessage()); } } /** *验证验证码 / public R checkRegisterEmailCode(String email, String code) { try { String redisCode = redisUtils.get(RestRedisConstant.REST_ELOG_REGISTER_EMAIL_CODE_KEY+email); //判断是否已过期 if (StringUtils.isEmpty(redisCode)){ return R.error("The E-mail verification code has expired, please try again."); } //判断验证码是否正确 if (!StringUtils.equals(redisCode,code)){ return R.error("The E-mail verification code is wrong. Please try again."); } //验证成功,从redis中移除该key&value redisUtils.delete(RestRedisConstant.REST_ELOG_REGISTER_EMAIL_CODE_KEY+email); return R.ok("The E-mail verification code has been verified."); }catch (Exception ex){ throw new RRException(ex.getMessage()); } }
说明:R.error (msg)/ throw new RRExcepion(msg)中,msg应该以enum或常量的方式组织起来;
在发送验证码、校验验证码时,应该有一个工具类,验证一个邮箱在特定的短时间内只能发送或验证几次验证码,超过此限制,应该拒绝处理请求;
