1. 申请授权码

在客户端设置，开启授权密码，记得保存，

2.直接上代码

public static void main(String[] args) {//接收方emailString receive="11111111@";//邮件主题String subject="生日祝福！";//邮件内容String content="祝您生日快乐！";//发送方String sendEmail="22222222@";// 授权码,之前所保存的String password="5dxxxxxxxxhe";try {//设置服务器验证信息Properties prop = new Properties();prop.setProperty("mail.smtp.auth", "true");// 加密端口(ssl) prop.setProperty("mail.smtp.timeout", "994");// SSL加密MailSSLSocketFactory sf = new MailSSLSocketFactory();// 设置信任所有的主机sf.setTrustAllHosts(true);prop.put("mail.smtp.ssl.enable", "true");prop.put("mail.smtp.ssl.socketFactory", sf);//设置邮件内容JavaMailSenderImpl javaMailSend = new JavaMailSenderImpl();MimeMessage message = javaMailSend.createMimeMessage();MimeMessageHelper messageHelper = new MimeMessageHelper(message, true, "utf-8");//设置昵称String nick = MimeUtility.encodeText(sendEmail);// 邮件发送者messageHelper.setFrom(new InternetAddress(nick + " <" + sendEmail + ">"));messageHelper.setTo(receive);messageHelper.setSubject(subject);messageHelper.setText(content, true);//设置邮件服务器登录信息javaMailSend.setHost("smtphz.");javaMailSend.setUsername(sendEmail);javaMailSend.setPassword(password);javaMailSend.setJavaMailProperties(prop);javaMailSend.send(message);} catch (Exception e) {e.printStackTrace();}}

引入的包：

import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeUtility;import com.sun.mail.util.MailSSLSocketFactory;​​​​​​​import org.springframework.mail.javamail.JavaMailSenderImpl;import org.springframework.mail.javamail.MimeMessageHelper;

以上代码简单调整即可使用（只修改基础信息即可）

3.如果出现报错

AuthenticationFailedException Read timed out

4.邮件模板发送可参照：
