阿里云上的使用QQ邮箱发送邮件

直接上代码了 由于阿里云禁用了25端口所以替换成465端口并修改协议为ssl才能发送邮件

参考我的另一篇博客

public class SendEmail {

    private static final Logger logger = LogManager.getLogger(SendEmail.class);

    private final static String smtpHost = "SMTP.qq.com";//配置Email session对象
    private final static String messageType = "text/html;charset=UTF-8";//相应内容类型，编码类型
    private final static String subject = "Imax(民大二手平台) 密码修改";//主题
    private final static String fromEmail = "[email protected]";//发送邮件的邮箱
    private final static String password = "thblmuldeba";//密码

    public boolean sendMessage(String to, String id, String username) {
        try {
            final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";//SSL加密
            MailSSLSocketFactory sf = new MailSSLSocketFactory();
            sf.setTrustAllHosts(true);
            String messageText = appendString(id, username);
            //第一步：配置javax.mail.Session对象
            Properties props = new Properties();   // 创建Properties 类用于记录邮箱的一些属性

            //第二步：编写消息
            InternetAddress fromAddress = new InternetAddress(fromEmail);// 设置发件人的邮箱
            InternetAddress toAddress = new InternetAddress(to); // 设置收件人的邮箱
            MimeMessage message = new MimeMessage(mailSession);

            message.setSubject(subject);   // 设置邮件标题
            message.setContent(messageText, messageType);// 设置邮件的内容体

            // 第三步：发送消息
            Transport transport = mailSession.getTransport("smtp");
            transport.connect(smtpHost, fromEmail, password);
            transport.send(message, message.getRecipients(RecipientType.TO)); // 发送邮件啦

            return false;
