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; for (int i = 0; i < to.length; i++) { addressTo = new InternetAddress(to); } 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);}
