@Service("mailService")
public class MailService {
@Autowired
private MailSender mailSender;
@Autowired
private SimpleMailMessage alertMailMessage;
@Resource(name = "freemarkerEmailConfig")
private Configuration emailConfiguration;
public void sendMail(String from, String to, String subject, String body) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(body);
mailSender.send(message);
}
public void sendAlertMail(String alert) {
SimpleMailMessage mailMessage = new SimpleMailMessage(alertMailMessage);
mailMessage.setText(alert);
mailSender.send(mailMessage);
}
}
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.mail.ru" />
<property name="port" value="465" />
<property name="username" value="[email protected]" />
<property name="password" value="***********" />
<property name="javaMailProperties">

</property>
<property name="to">

</property>
<property name="subject"
value="Alert - Exception occurred. Please investigate" />
</bean>
You need to pass in a map to the method that sends email with freemarker template. In your case the map will look something like:
Freemarker will resolve variable names based on the keys you passed in.
If you use Spring, then configure the template directory in applicationContext.xml like this:
Put your template under
templates/emailfolder (relative to your webapp). Inject thefreemarkerEmailConfigbean defined in applicationContext into your service class:Now in your service class you can use emailConfiguration to retrieve the template and then process it with the map above like this:
FreeMarkerTemplateUtils is a class from Spring. Now
textwill contain the html with the all the variables substituted by values from the map. Just send the email withtextas html content:
