spring.mail.host=smtp.mailtrap.io
spring.mail.port=2525
spring.mail.username=2d9a7d89fcc8f8
spring.mail.password=9bb8e9090abd96
EmailCfg :
#Component
public class EmailCfg {
#Value("${spring.mail.host}")
private String host;
#Value("${spring.mail.port}")
private int port;
#Value("${spring.mail.username}")
private String username;
#Value("${spring.mail.password}")
private String password;
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {

}
EmailMsg :
public class EmailMsg {
#NotNull
private String name;
#NotNull

private String email;
#NotNull
#Min(10)
private String feedback;
public String getName() {
return name;

Controller :
#CrossOrigin(origins = StringsConstants.FRONT_BASE_URL, maxAge = 3600)
#Api("Events Controller")
#RestController
#RequestMapping(StringsConstants.EVENTS_URL)
public class EventsController {
#Autowired
private EmailCfg emailCfg;
#PostMapping(value = "/sendMail")
#PreAuthorize("hasRole('USER')")
public void sendFeedback(#RequestBody EmailMsg feedback,
BindingResult bindingResult){
if(bindingResult.hasErrors()){
throw new ValidationException("Feedback is not valid");
}
// Create a mail sender
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost(this.emailCfg.getHost());
mailSender.setPort(this.emailCfg.getPort());
mailSender.setUsername(this.emailCfg.getUsername());
mailSender.setPassword(this.emailCfg.getPassword());
// Create an email instance
SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setFrom(feedback.getEmail());
mailMessage.setTo("rc#feedback.com");
mailMessage.setSubject("New feedback from " + feedback.getName());
mailMessage.setText(feedback.getFeedback());
// Send mail
mailSender.send(mailMessage);
