Spring发送邮件
JavaMail API为Java提供了邮件发送和接受服务,支持常见的邮件协议 SMTP IMAP POP3,
发送纯文本邮件
- public class Main {
- public static void main(String[] args) throws AddressException,
- MessagingException {
- // 直接使用JavaMail API:
- Properties props = new Properties();
- // 设置SMTP服务器:
- props.put("mail.smtp.host", "smtp.gmail.com");
- props.put("mail.smtp.port", "465");
- props.put("mail.smtp.auth", "true");
- // 使用SSL安全连接:
- props.put("mail.smtp.starttls.enable", "true");
- props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
- send(props, "livebookstore", // Username
- "LiVe-BoOkStOrE", // Password
- "livebookstore@gmail.com", // From
- new String[] { "livebookstore2@gmail.com" }, // To
- "A test mail", // Subject
- "测试使用JavaMail API发送邮件" // Text
- );
- }
- public static void send(Properties props, final String username,
- final String password, String from, String[] to, String subject,
- String text) throws AddressException, MessagingException {
- Session session = Session.getInstance(props, new Authenticator() {
- protected PasswordAuthentication getPasswordAuthentication() {
- return new PasswordAuthentication(username, password);
- }
- });
- session.setDebug(true);
- Message message = new MimeMessage(session);
- message.setFrom(new InternetAddress(from));
- message.setSubject(subject);
- message.setText(text);
- message.setSentDate(new Date());
- Address[] addressTo = new Address[to.length];
- for (int i = 0; i < to.length; i++) {
- addressTo[i] = new InternetAddress(to[i]);
- }
- message.setRecipients(Message.RecipientType.TO, addressTo);
- message.saveChanges();
- Transport.send(message, addressTo);
- }
- }
Spring提供了非常方便的Mail抽象层,它通过一个MailSender接口,封装了邮件发送Bean,
而SimpleMailMessage封装了纯文本的简单邮件
把发送邮件的STMP配置注入Bean中
- <!-- 配置MailSender -->
- <bean id="mailSender"
- class="org.springframework.mail.javamail.JavaMailSenderImpl">
- <property name="host" value="smtp.gmail.com" />
- <property name="port" value="465" />
- <property name="username" value="livebookstore" />
- <property name="password" value="LiVe-BoOkStOrE" />
- <property name="javaMailProperties">
- <props>
- <prop key="mail.smtp.auth">true</prop>
- <prop key="mail.smtp.starttls.enable">true</prop>
- <prop key="mail.smtp.socketFactory.class">
- javax.net.ssl.SSLSocketFactory
- </prop>
- </props>
- </property>
- </bean>
- // 使用Spring提供的MailSender:
- ApplicationContext context = new ClassPathXmlApplicationContext(
- "config.xml");
- JavaMailSender mailSender = (JavaMailSender) context.getBean("mailSender");
- sentBySpring(mailSender);
- private static void sentBySpring(JavaMailSender mailSender) {
- // 创建一个纯文本邮件:
- SimpleMailMessage mail = new SimpleMailMessage();
- mail.setFrom("livebookstore@gmail.com");
- mail.setTo("livebookstore2@gmail.com");
- mail.setSubject("Another test mail");
- mail.setText("测试使用Spring MailSender发送邮件");
- // 发送:
- mailSender.send(mail);
- }
发送Mime邮件
Spring提供助手类MimeMessageHepler,能方便的操作MimeMessage
- private static void sentMime(JavaMailSender mailSender)
- throws MessagingException {
- // 发送Mime邮件:
- MimeMessage mime = mailSender.createMimeMessage();
- MimeMessageHelper helper = new MimeMessageHelper(mime, true, "UTF-8");
- helper.setFrom("livebookstore@gmail.com");
- helper.setTo("livebookstore2@gmail.com");
- helper.setSubject("Test mime mail");
- // 设定为HTML格式:
- helper.setText("<html><body>访问Live在线书店:<br>"
- + "<a href='http://www.livebookstore.net' target='_blank'>"
- + "<img src='cid:logo'></a></body></html>", true);
- // 添加附件嵌入HTML中显示,在img标签中用"cid:xxx",
- // 对应附件通过addInline()添加
- helper.addInline("logo", new ClassPathResource("logo.gif"));
- helper.addAttachment("freebsd.gif", new ClassPathResource("freebsd.gif"));
- // 发送:
- mailSender.send(mime);
- }
