I'm trying to send a mail using Spring tool (via JavaMail library). I follow the directions on this link: http://www.codejava.net/frameworks/spring/sending-e-mail-with-spring-mvc#SpringEmail.
Firstly I thought that the bean was incorrect, but it seems correct to me.
<bean class="org.springframework.mail.javamail.JavaMailSenderImpl"
id="mailSender">
<!-- SMTP settings -->
<property value="smtp.gmail.com" name="host" />
<property value="587" name="port" />
<property value="xxxxxx@gmail.com" name="username" />
<property value="***********" name="password" />
<property name="javaMailProperties">
<!-- additional properties specific to JavaMail -->
<props>
<prop key="mail.transport.protocol">smtp</prop>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.starttls.enable">true</prop>
</props>
</property>
</bean>
The Implementation file I created is as follows:
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import gr.hua.intranet.model.Representative;
public class mailDAOImp implements mailDAO {
private DataSource dataSource;
private MailSender mailSender;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
@Override
public void SentConfirmation(Representative customer) {
mail NewMail = new mail();
NewMail.fastMailSet(customer, "Your registration confirmed", "Now you can log in to our Systems.\n"
+ "Username: " + customer.getAAM() + "\n Password: " + customer.getUsername(), null);
SimpleMailMessage email = new SimpleMailMessage();
email.setTo(NewMail.Address);
email.setSubject(NewMail.Sbj);
email.setText(NewMail.Msg);
// sends the e-mail
mailSender.send(email);
}
@Override
public void SentMail(Representative representative, String Reason, String msg) {
mail NewMail = new mail();
NewMail.fastMailSet(representative, "Newsletter: " + Reason, msg, null);
SimpleMailMessage email = new SimpleMailMessage();
email.setTo(NewMail.Address);
email.setSubject(NewMail.Sbj);
email.setText(NewMail.Msg);
// sends the e-mail
mailSender.send(email);
}
@Override
public void SentNewsLater(String Reason, String msg) {
String query = "SELECT * FROM NewsletterRecivers WHERE 1";
Representative representative = null;
Connection con = null;
PreparedStatement ps = null;
ResultSet rs = null;
try {
con = dataSource.getConnection();
ps = con.prepareStatement(query);
rs = ps.executeQuery();
while (rs.next()) {
representative = new Representative();
representative.setMail(rs.getString("Mail"));
SentMail(representative, Reason, msg);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
rs.close();
ps.close();
con.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
@Override
public void SenRegistrationCompletle(Representative customer) {
mail NewMail = new mail();
NewMail.fastMailSet(customer, "Newsletter registration is successful.",
"From now on you' ll recive newslatters.", null);
SimpleMailMessage email = new SimpleMailMessage();
email.setTo(NewMail.Address);
email.setSubject(NewMail.Sbj);
email.setText(NewMail.Msg);
// sends the e-mail
mailSender.send(email);
}
}
I the message seems not being null but mailSender.send(email) gives me:
