How to send Emails via Spring - spring

Question

In my JavaFx project I inject my controllers like so, which works fine:
#Configuration
public class AppFactory {
#Bean
public HomeController homeController() throws IOException {
return (HomeController) loadController("/wakiliproject/Home.fxml");
}
FXMLLoader loader = null;
protected Object loadController(String url) throws IOException {
loader = new FXMLLoader(getClass().getResource(url));
loader.load();
return loader.getController();
}
}
However, for non-controller classes, I get a null pointer exception, probably because the class never gets injected. Say, for example, I try to call a method in a non-controller class from another non-controller class like so:
Sending email via Spring, for example:
public class HomeController extends Application {
#Autowired
MailMail mailMail;
// Send email here
public void sendEmailMethod() {
System.out.println("Here ----------------------------------------------------------------");
mailMail.sendMail("olireylikesyou#gmail.com", "tryrevilo#yahoo.com", "Hello", "Subjecto");
}
// The other class methods
The other classes:
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com" />
<property name="username" value="mygmailusername#gmail.com" />
<property name="password" value="gmailpassword" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
</props>
</property>
</bean>
<bean id="mailMail" class="wakiliproject.ServerSide.EMail.MailMail">
<property name="mailSender" ref="mailSender" />
</bean>
--
public class MailMail {
private MailSender mailSender;
public void setMailSender(MailSender mailSender) {
this.mailSender = mailSender;
}
public void sendMail(String from, String to, String subject, String msg) {
//creating message
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(msg);
//sending message
mailSender.send(message);
}
}
The stacktrace:

Answer 1

had a similar problem... got me some attempts to configure it right in my application.properties (I'm injecting JavaMailSender using spring)
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.properties.mail.smtp.auth = true;
spring.mail.properties.mail.socketFactory.port=587
spring.mail.properties.mail.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.socketFactory.fallback=false
later i was required to enable looser security to my account during the test:
"change your settings at https://www.google.com/settings/security/lesssecureapps so that your account is no longer protected by modern security standards"
or i got an authentication error.
I hope that helps

According to Mladen Uzelac You need to set some properties for your SMTP connection.
