Here's an example for Gmail smtp:
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("[email protected]"));;
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("[email protected]", 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", "[email protected]", "<insert password here>");
t.sendMessage(msg, msg.getAllRecipients());
System.out.println("Response: " + t.getLastServerResponse());
t.close();
}
}
Now, do it this way only if you would like to keep your project dependencies to a minimum, otherwise i can warmly recommend using classes from apache
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，否则我可以热烈推荐使用来自 apache 的类

Another way is to use aspirin (https://github.com/masukomi/aspirin) like this:
另一种方法是像这样使用阿司匹林（https://github.com/masukomi/aspirin）：
MailQue.queMail(MimeMessage message)
..after having constructed your mimemessage as above.
..在按照上面构建你的 mimemessage 之后。
Aspirin isan smtp 'server' so you don't have to configure it. But note that sending email to a broad set of recipients isnt as simple as it appears because of the many different spam filtering rules receiving mail servers and client applications apply.
阿司匹林是一个 smtp“服务器”，因此您不必对其进行配置。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应用了许多不同的垃圾邮件过滤规则。

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);
}
