我想每月(第28天)发送一次自动电子邮件。在本地该方法有效并且已发送电子邮件,但是当我在服务器上部署该应用程序时,发送电子邮件的方法不起作用,因此该电子邮件不会发送给用户。
我不知道出什么问题了?
注意:云上的prod数据库(putty)。
该应用程序可以在prod上运行,并且没有出现任何问题,但是发送电子邮件的方法不起作用,因为它不发送电子邮件
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootHelloWorldApplication.class, args);
Class.forName("com.mysql.cj.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/...","name database","password");
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
int day = calendar.get(Calendar.DATE);
if(day == 28) {
Statement ccf = con.createStatement();
ResultSet ddj = ccf.executeQuery("SELECT gestion_cra.employe.email FROM gestion_cra.employe");
while(ddj.next()) {
String mel = ddj.getString("email");
JavaMailUtil.senMail(mel);
}
}
sendMail方法:
public static void senMail(String recepiant) throws MessagingException {
Properties properties = new Properties();
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.host", "send.one.com");
properties.put("mail.smtp.port", "587");
String MyAccountEmail = "mail";
String Password ="password";
Session session = Session.getDefaultInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(MyAccountEmail, Password);
}
});
Message message = prepareMessage(session, MyAccountEmail, recepiant);
Transport.send(message);
