First, need a dependency.
You can add dependency using mouse right click to pom.xml then typing mail.
Or this way.
Add this code.
-
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
Second, add package folder and java file Email.java, EmailSender.java.
Email.java is setter and getter, EmailSender.java is sender.
This is Email.java
public class Email {
-
-
-
-
return receiver;
}
public void setReceiver
(String receiver
) {
this.receiver = receiver;
}
-
return subject;
}
public void setSubject
(String subject
) {
this.subject = subject;
}
-
return content;
}
public void setContent
(String content
) {
this.content = content;
}
}
Email.java consist of subject, content and receiver.
This is EmailSender.java
import javax.mail.MessagingException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailException;
import org.springframework.mail.javamail.JavaMailSender;
public class EmailSender {
@Autowired
protected JavaMailSender mailSender;
public void SendEmail(Email email) throws Exception {
MimeMessage msg = mailSender.createMimeMessage();
try {
msg.setSubject(email.getSubject());
msg.setText(email.getContent());
msg.setRecipients(MimeMessage.RecipientType.TO , InternetAddress.parse(email.getReceiver()));
}catch(MessagingException e) {
System.
out.
println("MessagingException");
e.printStackTrace();
}
try {
mailSender.send(msg);
}catch(MailException e) {
System.
out.
println("MailException발생");
e.printStackTrace();
}
}
}
EmailSender getting content, receiver and subject from Email.java then Sending using JavaMailSender.
This is Controller code.
@Autowired
private EmailSender emailSender;
@Autowired
private Email email;
@RequestMapping("/sendpw.do")
public ModelAndView sendEmailAction
(@RequestParam Map<
String, Object> paramMap, ModelMap model
) throws Exception {
ModelAndView mav;
-
-
String pw=mainService.
getPw(paramMap
);
-
if(pw!=null) {
email.setContent("비밀번호는 "+pw+" 입니다.");
email.setReceiver(e_mail);
email.setSubject(id+"님 비밀번호 찾기 메일입니다.");
emailSender.SendEmail(email);
mav= new ModelAndView("redirect:/login.do");
return mav;
}else {
mav=new ModelAndView("redirect:/logout.do");
return mav;
}
}
This code getting id and e-mail from jsp.
And check the information.
If id and e-mail is right getting password from database.
This is bean setting.
<!-- gmail -->
<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >
<property name="host" value="smtp.gmail.com" />
<property name="port" value="587" />
<property name="defaultEncoding" value="utf-8"/>
<property name="username" value="your id@gmail.com" />
<property name="password" value="your password" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.starttls.enable">true</prop>
<prop key="mail.smtp.auth">true</prop>
</props>
</property>
</bean>
<bean id="email" class="spring.board.email.Email">
</bean>
<bean id="emailSender" class="spring.board.email.EmailSender">
