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，只有当您希望将项目依赖性保持在最低限度时才这样做，否则我可以热烈推荐使用来自apache的类

http://commons.apache.org/email/

此致

另一种方法是使用阿司匹林（https://github.com/masukomi/aspirin），如下所示：

MailQue.queMail(MimeMessage message)

..在构建了你的mimemessage之后。

Aspirin 是 smtp'服务器'，因此您无需进行配置。但请注意，向广泛的收件人发送电子邮件并不像看起来那么简单，因为接收邮件服务器和客户端应用程序的许多不同垃圾邮件过滤规则都适用。

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*; 

public void postMail(String recipients[], String subject,
    String message , String from) throws MessagingException {

    //Set the host smtp address
    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.jcom.net");

    // create some properties and get the default Session
    Session session = Session.getDefaultInstance(props, null);
    session.setDebug(false);

    // create a message
    Message msg = new MimeMessage(session);

    // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);

    InternetAddress[] addressTo = new InternetAddress[recipients.length]; 
    for (int i = 0; i < recipients.length; i++) {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
    msg.setRecipients(Message.RecipientType.TO, addressTo);

    // Optional : You can also set your custom headers in the Email if you Want
    msg.addHeader("MyHeaderName", "myHeaderValue");

    // Setting the Subject and Content Type
    msg.setSubject(subject);
    msg.setContent(message, "text/plain");
    Transport.send(msg);
}
