前置

说明：实现qq邮箱发送信息，可以不用redis

1.开启POP3/SMTP服务

里面会要求发送短信，并得到密码，这个验证码后面会用到

2.依赖导入

email依赖

<!-- 发送邮箱--><dependency><groupId>commons-email</groupId><artifactId>commons-email</artifactId><version>1.1</version></dependency><dependency><groupId>javax.mail</groupId><artifactId>mail</artifactId><version>1.4.7</version></dependency><dependency><groupId>javax.activation</groupId><artifactId>activation</artifactId><version>1.1.1</version></dependency>

redis依赖

<!-- 整合redis --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><!--spring2.X集成redis所需common-pool2--><dependency><groupId>mons</groupId><artifactId>commons-pool2</artifactId><version>2.6.0</version></dependency>

3.写业务

redis配置类，用的时候直接粘贴

@Configuration//表示配置类@EnableCaching//表示缓存注解public class RedisConfig extends CachingConfigurerSupport {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, Object> template = new RedisTemplate<>();RedisSerializer<String> redisSerializer = new StringRedisSerializer();Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);ObjectMapper om = new ObjectMapper();om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(om);template.setConnectionFactory(factory);//key序列化方式template.setKeySerializer(redisSerializer);//value序列化template.setValueSerializer(jackson2JsonRedisSerializer);//value hashmap序列化template.setHashValueSerializer(jackson2JsonRedisSerializer);return template;}@Beanpublic CacheManager cacheManager(RedisConnectionFactory factory) {RedisSerializer<String> redisSerializer = new StringRedisSerializer();Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);//解决查询缓存转换异常的问题ObjectMapper om = new ObjectMapper();om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(om);// 配置序列化（解决乱码的问题）,过期时间600秒RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofSeconds(600)).serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer)).serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)).disableCachingNullValues();RedisCacheManager cacheManager = RedisCacheManager.builder(factory).cacheDefaults(config).build();return cacheManager;}}

application.properties配置

补充：SMTP协议：smtps（端口465）v.msa（端口587）端口465和587用于电子邮件客户端到电子邮件服务器通信

msm.email=自己邮箱# hostmsm.host=# 端口 587和465都可以msm.port=587# 发送短信的密码msm.password=上面的密码spring.redis.host=hadoop102spring.redis.port=6379spring.redis.database= 0spring.redis.timeout=1800000spring.redis.lettuce.pool.max-active=20spring.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=5spring.redis.lettuce.pool.min-idle=0

创建一个右键的工具类获取参数

@Componentpublic class EmailUtils implements InitializingBean {@Value("${msm.email}")private String email;@Value("${msm.host}")private String host;@Value("${msm.port}")private String port;@Value("${msm.password}")private String password;public static String EMAIL;public static String HOST;public static String PORT;public static String PASSWORD;@Overridepublic void afterPropertiesSet() throws Exception {this.EMAIL = email;this.HOST = host;this.PORT = port;this.PASSWORD = password;}}

serviceImpl实现方法

@Servicepublic class MsmServiceImpl implements MsmService {@Overridepublic Boolean send(Map<String, Object> param, String email) {if(StringUtils.isEmpty(email)) return false;try {SimpleEmail mail = new SimpleEmail();mail.setSslSmtpPort(EmailUtils.PORT);mail.setHostName(EmailUtils.HOST);// 设置密码验证器mail.setAuthentication(EmailUtils.EMAIL, EmailUtils.PASSWORD);// 设置邮件发送者mail.setFrom(EmailUtils.EMAIL);mail.addTo(email);// 设置邮件编码mail.setCharset("UTF-8");// 设置邮件主题mail.setSubject("浪浪课间");// 设置邮件内容mail.setMsg("10分钟内有效,您的验证码为："+param.get("code"));// 设置邮件发送时间mail.setSentDate(new Date());// 发送邮件mail.send();return true;} catch (EmailException e) {throw new GuliException(20001,"邮件发送异常");}}

controller层

@RestController@RequestMapping("/edumsm/msm")@CrossOriginpublic class MsmController {@Autowiredprivate MsmService msmService;@Autowiredprivate RedisTemplate<String,String> redisTemplate;// 发送短信方法@GetMapping("send/{email}")public R sendMsm(@PathVariable String email){// 1.先从redis获取验证码，如果获取到直接返回String s = redisTemplate.opsForValue().get(email);if(!StringUtils.isEmpty(s)){return R.ok();}// 如果redis获取不到，进行邮件的发送// 生成随机数，传递到邮箱进行发送String code= RandomUtil.getFourBitRandom();Map<String,Object> param =new HashMap<>();param.put("code",code);// 调用service里面短信调用的方法Boolean isSend=msmService.send(param,email);if(isSend){// 发送成功，把发送成功的验证码再放到redis中// 设置有效时间// 设置5分钟redisTemplate.opsForValue().set(email,code,5, TimeUnit.MINUTES);return R.ok();}else {return R.error().message("邮箱发送失败");}}}

4.测试

打开swagger接口进行测试

结果：

邮件：

redis获取数据
