首先需要导入javax.mail.jar包，下载地址为https://java.net/projects/javamail/pages/Home

163邮箱需要打开客户端授权码

 

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

public class Email {
    public static void main(String[] args) throws Exception {
        Properties props = new Properties();
        props.setProperty("mail.host", "smtp.163.com");//设置发送主机
        props.setProperty("mail.smtp.auth", "true");// 设置是否需要验证
        Authenticator auth = new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("hfutlj", "********");//密码为163客户端授权码，不是登录密码
            }
        };
        Session session = Session.getInstance(props, auth);
        MimeMessage message = new MimeMessage(session);
        String nick = "";
        nick = javax.mail.internet.MimeUtility.encodeText("张三");//昵称的处理，否则为乱码
        message.setFrom(new InternetAddress(nick + "<[email protected]>"));
        message.setRecipient(RecipientType.TO, new InternetAddress("[email protected]"));
        message.setRecipient(RecipientType.CC, new InternetAddress("[email protected]"));

        message.setSubject("测试邮件");
        message.setContent("注意正文和标题部分不能写test、helloword等否则会被163视为垃圾邮件，报534错误", "text/html;charset=utf-8");

        Transport.send(message);
    }

}
