springboot通过qq邮箱发邮件失败？？

Question

application.properties配置信息

spring.mail.host=smtp.qq.com  
spring.mail.protocol=smtp  
spring.mail.default-encoding=UTF-8  
spring.mail.password=********** 
spring.mail.username=1*****[e-mail]  
spring.mail.port=465  
spring.mail.properties.mail.stmp.socketFactory.class=javax.net.ssl.SSLSocketFactory  
spring.mail.properties.mail.stmp.socketFactory.port=465  
spring.mail.properties.mail.debug=true  
spring.mail.properties.mail.smtp.auth=true  
spring.mail.properties.mail.smtp.starttls.enable=true  
spring.mail.properties.mail.smtp.starttls.required=true

发送邮件代码：

`SimpleMailMessage msg = new SimpleMailMessage();  
  msg.setTo("1588974**@163.com");  
  msg.setFrom("122******[e-mail]");  
  msg.setSubject("测试");  
  msg.setSentDate(new Date());  
  msg.setText("测试邮件");  
  javaMailSender.send(msg);`

我已经开启了qq的SMTP服务。授权码是正确的。但是还是不能发送邮件

报错信息：

DEBUG: JavaMail version 1.6.2
DEBUG: successfully loaded resource: /META-INF/javamail.default.address.map
DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Oracle]
DEBUG SMTP: useEhlo true, useAuth true

DEBUG SMTP: EOF: [EOF]
DEBUG SMTP: could not connect to host "smtp.qq.com", port: 465, response: -1

题主贴出的配置和代码有两个问题：
1、端口号。根据QQ邮箱的官方说明，端口号可以是465或587，但我测试的时候465是超时的，587就正常。
2、运行贴出的代码尝试发邮件，会报错，报错信息

java.net.ConnectException: Connection refused: connect. Failed messages: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: localhost, 25; timeout -1;

根据这个信息，host和port这两个参数都没有作为参数传入，运行的时候压根就没有连去QQ邮箱的服务器。

因为弄了一轮都发不出，于是归零重新找资料实现。
下面是我的代码，参考的是spring的官方文档。
配置文件沿用题主的。用了springboot，版本号2.2.3.RELEASE。

package zsh.sf_answer1.mail;

        JavaMailSenderImpl sender = new JavaMailSenderImpl();
        sender.setHost(host);//发件邮箱
        sender.setUsername(username);//*1
        sender.setPassword(password);
        sender.setPort(Integer.parseInt(port));
        MimeMessage message = sender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message);
        helper.setFrom(username);//与*1要一致，不配置会报错
        helper.setSubject("TestMail Type I");
        helper.setTo(sendTo);//收件邮箱
        helper.setText("Thank you for ordering!");//邮件内容
        helper.setSentDate(new Date());

        }catch(Exception e) {
            e.printStackTrace();
        }
    }

    String host;
    String username;
    String password;
    String port;

    @Autowired
    public void setUsername(@Value("${spring.mail.username}") String username) {
