Spring Gossip: HTML郵件

如果要使用HTML郵件的話，可以使用Spring的org.springframework.mail.javamail.MimeMessageHelper來建立HTML郵件，，直接使用實例來作示範：

HTMLMailDemo.java

package onlyfun.caterpillar;

import org.springframework.mail.javamail.JavaMailSenderImpl;
import javax.mail.internet.MimeMessage;
import org.springframework.mail.javamail.MimeMessageHelper;

public class HTMLMailDemo {
    public static void main(String[] args) throws Exception {
        JavaMailSenderImpl senderImpl = 
            new JavaMailSenderImpl();
        
        // 設定 Mail Server
        senderImpl.setHost("your_mail_server.com"); 
        
        // 建立郵件訊息
        MimeMessage mailMessage = 
            senderImpl.createMimeMessage();
        MimeMessageHelper messageHelper = 
            new MimeMessageHelper(mailMessage);
                
        // 設定收件人、寄件人、主題與內文
        messageHelper.setTo("xxx@your_mail_server.com");
        messageHelper.setFrom("xxx@your_mail_server.com");
        messageHelper.setSubject("Test");
        messageHelper.setText(
                "<html><head></head><body><h1>Hello! Spring!"
                + "</h1></body></html>", true);
        
        // 傳送郵件
        senderImpl.send(mailMessage); 
        
        System.out.println("郵件傳送OK...");
    }
}

在MimeMessageHelper類別的setText()方法上的boolean參數設定為true時，表示要啟用HTML格式的郵件。
