如何从 Java 发送 SMTP 消息？

Answer 1

以下是 Gmail smtp 的示例:

import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;

import javax.mail.*;

import javax.mail.internet.*;

import com.sun.mail.smtp.*;


public class Distribution {

    public static void main(String args[]) throws Exception {
        Properties props = System.getProperties();
        props.put("mail.smtps.host","smtp.gmail.com");
        props.put("mail.smtps.auth","true");
        Session session = Session.getInstance(props, null);
        Message msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress("mail@tovare.com"));;
        msg.setRecipients(Message.RecipientType.TO,
        InternetAddress.parse("tov.are.jacobsen@iss.no", false));
        msg.setSubject("Heisann "+System.currentTimeMillis());
        msg.setText("Med vennlig hilsennTov Are Jacobsen");
        msg.setHeader("X-Mailer", "Tov Are's program");
        msg.setSentDate(new Date());
        SMTPTransport t =
            (SMTPTransport)session.getTransport("smtps");
        t.connect("smtp.gmail.com", "admin@tovare.com", "<insert password here>");
        t.sendMessage(msg, msg.getAllRecipients());
        System.out.println("Response: " + t.getLastServerResponse());
        t.close();
    }
}

现在，仅当您希望将项目依赖项保持在最低限度时才这样做，否则我强烈建议您使用来自 apache 的类
