java发送qq邮件

1.登录qq邮箱

1）点击设置

2）点击账户

3）开启第一个服务，我已经开过了

4）开启验证（让你发送指定内容到某个号码），完成后点击我已发送，就会出现授权码，授权码很重要保留好

2.java操作来发送qq邮件

1）引入依赖

        <dependency><groupId>javax.mail</groupId><artifactId>mail</artifactId><version>1.4.7</version></dependency>

2）相关代码

public class QQSMSUtils {public static void main(String[] args) throws Exception {testMail();}private static void testMail () throws Exception {// 给用户发送邮件的邮箱final String from = "1137625116@qq.com";// 邮箱的用户名final String username = "1137625116@qq.com";// 邮箱授权码，刚刚保存的授权码，不是qq密码final String password = "oiknpwwrimuahghf";// 发送邮件的服务器地址，QQ服务器final String host = "smtp.qq.com";// 接收人邮箱final String to = "2864254910@qq.com";// 邮件主题final String title = "验证码发送";// 使用QQ邮箱时配置Properties prop = new Properties();prop.setProperty("mail.host", "smtp.qq.com");    // 设置QQ邮件服务器prop.setProperty("mail.transport.protocol", "smtp");      // 邮件发送协议prop.setProperty("mail.smtp.auth", "true");      // 需要验证用户名和密码// 关于QQ邮箱，还要设置SSL加密，其他邮箱不需要
//            MailSSLSocketFactory sf = new MailSSLSocketFactory();
//            sf.setTrustAllHosts(true);
//            prop.put("mail.smtp.ssl.enable", "true");
//            prop.put("mail.smtp.ssl.socketFactory", sf);// 创建定义整个邮件程序所需的环境信息的 Session 对象，QQ才有，其他邮箱就不用了Session session = Session.getDefaultInstance(prop, new Authenticator() {@Overrideprotected PasswordAuthentication getPasswordAuthentication() {// 发件人邮箱用户名，授权码return new PasswordAuthentication(username, password);}});// 开启 Session 的 debug 模式，这样就可以查看程序发送 Email 的运行状态session.setDebug(true);// 通过 session 得到 transport 对象Transport ts = session.getTransport();// 使用邮箱的用户名和授权码连上邮箱服务器ts.connect(host, username, password);// 创建邮件，写邮件MimeMessage message = new MimeMessage(session);message.setFrom(new InternetAddress(from)); // 指明邮件的发件人message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));   // 指明邮件的收件人message.setSubject(title);     // 邮件主题message.setContent("验证码为:8824", "text/html;charset=utf-8");    // 邮件内容// 发送邮件ts.sendMessage(message, message.getAllRecipients());System.out.println("验证码发送成功");// 释放资源ts.close();}}

关于QQ邮箱，还要设置SSL加密，其他邮箱不需要这段内容我注释掉了，不然报错

3）点击运行，发送成功，控制台输出
