發送電子郵件在我的JavaFX項目我注入我的控制器像這樣，這工作得很好：如何通過Spring
@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();
}
}
然而，對於非控制類，我得到一個空指針異常，可能是因爲類永遠不會被注射。說，例如，我嘗試調用在非控制器類的方法從另一個非控制器類，像這樣：
通過Spring發送電子郵件，例如：
public class HomeController extends Application {
@Autowired
MailMail mailMail;
// Send email here
public void sendEmailMethod() {
System.out.println("Here ----------------------------------------------------------------");
mailMail.sendMail("[email protected]", "[email protected]", "Hello", "Subjecto");
}
// The other class methods
其他類：
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com" />
<property name="username" value="[email protected]" />
<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);
}
}

似乎你有發送郵件配置的問題。你配置了「STARTTLS」嗎？ – 2014-11-06 07:43:17
