Java、Spring：邮件发送不成功，会是什么问题呢？

Question

QQ邮箱的相关服务均已开启，代码如下：public class Demo {    public static void main(String[] args) {        JavaMailSenderImpl sender = new JavaMailSenderImpl();        sender.setHost("smtp.qq.com");        sender.setPort(465);        sender.setUsername("********@qq.com");        sender.setPassword("********");            Properties pro = System.getProperties();        pro.put("mail.smtp.auth", "true");        pro.put("mail.smtp.timeout", "25000");        sender.setJavaMailProperties(pro);        MimeMessage message = sender.createMimeMessage();        try {            MimeMessageHelper helper = new MimeMessageHelper(message, true);            helper.setFrom("********@qq.com"); // 发送人             helper.setTo("********@126.com"); // 收件人              helper.setSubject("Title"); // 标题            helper.setText("Content"); // 内容            sender.send(message);            System.out.println("发送完毕！");        } catch (MessagingException e) {            e.printStackTrace();        } catch (Exception e) {25秒超时后报错如下：org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.qq.com, port: 465. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: smtp.qq.com, port: 465; message exception details (1) are:Failed message 1:javax.mail.MessagingException: Could not connect to SMTP host: smtp.qq.com, port: 465    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:899)    at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:158)    at javax.mail.Service.connect(Service.java:233)    at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:389)    at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:340)    at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:336)    at Demo.main(Demo.java:31)有的邮箱密码不填邮箱密码，而是填分配的授权码，我用邮箱密码、授权码都不行...
