本篇內容主要講解“springboot中JavaMailer使用ssl發送郵件”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實用性強。下面就讓小編來帶大家學習“springboot中JavaMailer使用ssl發送郵件”吧!
springboot使用發送郵件非常簡單,都已經封裝好了
首先就是引入依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
然后配置發送郵箱的用戶名密碼等,這里以使用騰訊企業郵箱為例,因為需要配置了ssl,所以需要配置額外屬性properties,若不配置額外屬性使用默認配置端口25也可以發送,但有些情況不行,比如阿里云的ecs內就不允許訪問外網的25端口,因為被阿里云限制了。
spring: mail: host: smtp.exmail.qq.com username: 10000@qq.com password: 12345678 default-encoding: utf-8 properties: '[mail.smtp.auth]': true '[mail.smtp.timeout]': "5000" '[mail.smtp.socketFactory.port]': "465" '[mail.smtp.socketFactory.fallback]': false '[mail.smtp.socketFactory.class]': "javax.net.ssl.SSLSocketFactory"
然后使用javamail發送郵件
@ConditionalOnProperty(prefix = "spring.mail", name = "host") @Service public class CommonMailSender { @Value("${spring.mail.username}") private String from; @Autowired private JavaMailSender mailSender; /** * 簡單文本郵件 * @param to 接收者郵件 * @param subject 郵件主題 * @param contnet 郵件內容 */ @Async public void sendSimpleMail(String to, String subject, String contnet){ SimpleMailMessage message = new SimpleMailMessage(); message.setTo(to); message.setSubject(subject); message.setText(contnet); message.setFrom(from); mailSender.send(message); } /** * HTML 文本郵件 * @param to 接收者郵件 * @param subject 郵件主題 * @param contnet HTML內容 * @throws MessagingException */ @Async public void sendHtmlMail(List<String> to, String subject, String contnet) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setTo(to.toArray(new String[] {})); helper.setSubject(subject); helper.setText(contnet, true); helper.setFrom(from); mailSender.send(message); } /** * HTML 文本郵件 * @param to 接收者郵件 * @param subject 郵件主題 * @param contnet HTML內容 * @throws MessagingException */ @Async public void sendHtmlMail(String to, String subject, String contnet) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setTo(to); helper.setSubject(subject); helper.setText(contnet, true); helper.setFrom(from); mailSender.send(message); } /** * 附件郵件 * @param to 接收者郵件 * @param subject 郵件主題 * @param contnet HTML內容 * @param filePath 附件路徑 * @throws MessagingException */ @Async public void sendAttachmentsMail(String to, String subject, String contnet, String filePath) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setTo(to); helper.setSubject(subject); helper.setText(contnet, true); helper.setFrom(from); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = file.getFilename(); helper.addAttachment(fileName, file); mailSender.send(message); } }
注意這里的發送郵件方法會阻塞進程,所以使用了異步注解@Async
默認異步方法每次調用都會啟用一個新線程執行,非常耗資源,所以這里還需要配置一下異步的線程池
@Configuration @EnableAsync public class AsyncConfig extends AsyncConfigurerSupport { @Override public Executor getAsyncExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(7); executor.setMaxPoolSize(42); executor.setQueueCapacity(11); executor.setThreadNamePrefix("AsyncExecutor-"); executor.initialize(); return executor; } @Override public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() { return new SimpleAsyncUncaughtExceptionHandler(); } }
