How to insert table in mail with java mail service
Inserting a table in an email using JavaMail service can be a bit tricky, but it's doable. Here's a step-by-step guide to help you achieve this:
Step 1: Create a table as a HTML string
First, you need to create a table as a HTML string. You can use a library like Apache POI to generate the table, or you can create it manually. Here's an example of a simple table:
<table border="1" cellpadding="5" cellspacing="0">
<tr>
<th>Column 1</th>
<th>Column 2</th>
</tr>
<tr>
<td>Row 1, Cell 1</td>
<td>Row 1, Cell 2</td>
</tr>
<tr>
<td>Row 2, Cell 1</td>
<td>Row 2, Cell 2</td>
</tr>
</table>
Step 2: Create a MimeMessage
Next, you need to create a MimeMessage
object using JavaMail API. You can do this by creating a MimeMessage
object and setting its content type to text/html
.
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
// Create a MimeMessage object
MimeMessage message = new MimeMessage(session);
// Set the content type to text/html
message.setContentType("text/html");
Step 3: Set the table as the email body
Now, you need to set the table as the email body. You can do this by creating a MimeBodyPart
object and setting its content to the HTML table string.
// Create a MimeBodyPart object
MimeBodyPart bodyPart = new MimeBodyPart();
// Set the content to the HTML table string
bodyPart.setContent(tableHtmlString, "text/html");
Step 4: Add the body part to the message
Finally, you need to add the body part to the message. You can do this by creating a Multipart
object and adding the body part to it.
// Create a Multipart object
Multipart multipart = new MimeMultipart();
// Add the body part to the multipart
multipart.addBodyPart(bodyPart);
// Set the multipart as the message body
message.setContent(multipart);
Step 5: Send the email
Now, you can send the email using the Transport
object.
// Send the email
Transport.send(message);
Here's the complete code:
import javax.mail.*;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
import java.util.Properties;
public class SendEmailWithTable {
public static void main(String[] args) {
// Create a Properties object
Properties props = new Properties();
props.put("mail.smtp.host", "your-smtp-host");
props.put("mail.smtp.port", "your-smtp-port");
props.put("mail.smtp.auth", "true");
// Create a Session object
Session session = Session.getInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("your-email", "your-password");
}
});
// Create a MimeMessage object
MimeMessage message = new MimeMessage(session);
// Set the content type to text/html
message.setContentType("text/html");
// Create a table as a HTML string
String tableHtmlString = "<table border=\"1\" cellpadding=\"5\" cellspacing=\"0\">\n" +
" <tr>\n" +
" <th>Column 1</th>\n" +
" <th>Column 2</th>\n" +
" </tr>\n" +
" <tr>\n" +
" <td>Row 1, Cell 1</td>\n" +
" <td>Row 1, Cell 2</td>\n" +
" </tr>\n" +
" <tr>\n" +
" <td>Row 2, Cell 1</td>\n" +
" <td>Row 2, Cell 2</td>\n" +
" </tr>\n" +
"</table>";
// Create a MimeBodyPart object
MimeBodyPart bodyPart = new MimeBodyPart();
// Set the content to the HTML table string
bodyPart.setContent(tableHtmlString, "text/html");
// Create a Multipart object
Multipart multipart = new MimeMultipart();
// Add the body part to the multipart
multipart.addBodyPart(bodyPart);
// Set the multipart as the message body
message.setContent(multipart);
// Send the email
Transport.send(message);
}
}
Note that you need to replace the placeholders (your-smtp-host
, your-smtp-port
, your-email
, and your-password
) with your actual email settings.
