Spring 메일보내기

간단하게 메일보내는 기능이 필요해서 간단하게만 작업했다. javamail라이브러리를 찾아 mail.jar를 추가해주고, servlet.xml에 아래와 같이 추가해준다.

@Controller
public class AdgameController {
 SqlMapClientTemplate smct;
 private MailSender mailSender;
 
 public AdgameController(SqlMapClientTemplate smct,MailSender mailsender) { //생성자
  this.smct = smct;
  this.mailSender=mailsender;
        }
 
 
 
        @RequestMapping("/sendmail.html")
 public void sendMail(HttpServletRequest req,HttpServletResponse res){
 
  String title = req.getParameter("title");
  String content = req.getParameter("content");
 
          SimpleMailMessage message = new SimpleMailMessage();
  message.setFrom("보내는사람@이메일주소");
  message.setSubject(title);
  message.setText(content);
 
  message.setTo("받는사람@이메일주소");
  mailSender.send(message);
  
 }
} 

정말 심플하다.
