怎么用JAVA实现邮件发送

怎么用JAVA实现邮件发送

一个小例子，也可使用其他api
import java.util.Properties;import javax.mail.Address;import javax.mail.Authenticator;import javax.mail.BodyPart;import javax.mail.Message;import javax.mail.Multipart;import javax.mail.PasswordAuthentication;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;import javax.mail.internet.MimeUtility;public class Test {// testpublic static void main(String[] args) throws Exception {sendEmail("smtp.163.com", "测试", "测试", "！！！收件人地址！！！", "！！！发件人邮箱用户名！！！", "！！！邮箱密码！！！", "发件人昵称");}/** * * @param smtp * @throws Exception */public static void sendEmail(String emailServer, String subject, String mailBody, String receiver, final String username, final String password, String nickname) throws Exception {Properties props = new Properties();props.put("mail.smtp.auth", "true");props.setProperty("mail.transport.protocol", "smtp");props.setProperty("mail.smtp.host", emailServer);props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");props.setProperty("mail.smtp.socketFactory.fallback", "false");props.setProperty("mail.smtp.port", "465");props.setProperty("mail.smtp.socketFactory.port", "465");Session session = Session.getDefaultInstance(props, new Authenticator() {protected PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication(username, password);}});session.setDebug(true);MimeMessage mimeMsg = new MimeMessage(session);Multipart mp = new MimeMultipart();mimeMsg.setSubject(MimeUtility.encodeText(subject, "utf-8", null));nickname = MimeUtility.encodeText(nickname, "utf-8", null);mimeMsg.setFrom(new InternetAddress(username, nickname, "UTF-8"));BodyPart bp = new MimeBodyPart();bp.setContent(mailBody, "text/html;charset=utf-8");mp.addBodyPart(bp);mimeMsg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(receiver));mimeMsg.setContent(mp);mimeMsg.saveChanges();Transport transport = session.getTransport();transport.connect(username, password);Address[] allRecipients = mimeMsg.getAllRecipients();transport.sendMessage(mimeMsg, allRecipients);transport.close();}}2017-07-25
