why does mailSender always get as a null? spring/jsf - spring

Question

I tried to send mail with spring in managedbean(jsf).But I get a nullpointer exception.
MailServiceImpl.class
#Service("MailService")
public class MailServiceImpl implements MailService, Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
#Autowired
private JavaMailSender mailSender;
#Autowired
private SimpleMailMessage alertMailMessage;
Logger log = Logger.getLogger(getClass());
#Override
public void sendMail(String from, String to, String subject, String body) {
try {
final SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(body);
if (mailSender != null) {
mailSender.send(message);
} else {
log.info("mailSender is null." + mailSender);
}
} catch (final MailException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
#Override
public void sendAlertMail(String alert) {
final SimpleMailMessage mailMessage = new SimpleMailMessage(
alertMailMessage);
mailMessage.setText(alert);
mailSender.send(mailMessage);
}
public JavaMailSender getMailSender() {
return mailSender;
}
public void setMailSender(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
}

mailSender always gets as a null.Why?How can I send an email properly?Thanks in advance.

Answer 1

I suspect in this case in the JSF bean you get an instance of the MailServiceImpl injected, which was created by the CDI container (or maybe JSF itself) and not Spring, so the fields in the object are null (obviously, because the CDI container doesn't know anything about Spring annotations).
If you want to inject Spring beans in a JSF managed bean, you have to put the following snippet in the faces-config class:
<application>
<el-resolver>
org.springframework.web.jsf.el.SpringBeanFacesELResolver
</el-resolver>
</application>
