我面臨無法發送電子郵件的事實。我不明白原因。我使用 Spting Boot 2。該示例使用 JavaMailSender 類。但是你可以不用它的實現和在 application.properties 中指定的必要參數嗎？@Configurationpublic class MainConfiguration { @Bean public JavaMailSender getJavaMailSender() { JavaMailSenderImpl mailSender = new JavaMailSenderImpl(); mailSender.setHost("smtp.yandex.ru"); mailSender.setPort(465); mailSender.setUsername("[email protected]"); mailSender.setPassword("test122223"); Properties props = mailSender.getJavaMailProperties(); props.put("mail.transport.protocol", "smtp"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.debug", "true"); props.put("mail.smtp.socketFactory.port", "465"); props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory"); //props.put("mail.smtp.timeout", 1000); return mailSender; } @Bean public SimpleMailMessage templateSimpleMessage() { SimpleMailMessage message = new SimpleMailMessage(); message.setText("This is the test email template for your email:"); return message; }}2 分鐘后，出現錯誤："javax.mail.MessagingException: Could not connect to SMTP host"

嘗試添加
spring.mail.properties.mail.smtp.ssl.enable=true
或者
props.put("mail.smtp.ssl.enable", "true");
我不明白你為什么要使用配置類，如果你使用的是 spring boot 2，你可以將所有電子郵件配置放在你的 application.properties 文件中：
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.ssl.enable=true
spring.mail.host=smtp.yandex.ru
spring.mail.port=465
spring.mail.password=test122223

試試這個代碼：
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"[email protected]"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
try{
startActivity(Intent.createChooser(i, "Send mail..."));
}
catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MyActivity.this, "There are no email clients installed.",
Toast.LENGTH_SHORT).show();
}
