通过从数据库获取邮件结构在JAVA中发送邮件

问题描述 投票：0回答：1

我必须使用Java在ADF中发送邮件，但是邮件结构来自数据库，但是我不知道如何使用该结构并将动态值分配给它。以下是结构：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:template match="/">
        <html>

下面是我发送邮件的班级>>


import java.time.LocalDate;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

public class Mail {
    public static void main(String[] args) {

        String host = "smtp.gmail.com";
        final String user = "test.";// change accordingly
        final String password = "Wel";// change accordingly

        String to = "[email protected]";// change accordingly
        StringBuilder msg = new StringBuilder();

        // Get the session object
        Properties props = new Properties();
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.ssl.trust", "smtp.gmail.com");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.port", "587");

        Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(user, password);
            }
        });

        // Compose the message
        try {
            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(user));
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            message.setSubject("Dummy Email");
            message.setContent(text, "text/html");

            // send the message
            Transport.send(message);

            System.out.println("message sent successfully...");

        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

请告诉我如何在运行时通过使用JAVA从数据库获取该结构来为空文本框设置值
