首先要开启QQ邮箱SMTP/POP3服务 获取秘钥 为emaillPass
写在配置文件中
emailPass=XXXXXXXXhosts=smtp.qq.comfromAddress=XXXXXX@qq.comemailusername=XXXXXXdada
代码如下:
package com.zk.shop.utils;import java.util.Properties;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Component;import com.sun.mail.util.MailSSLSocketFactory;/** * JavaMail发送邮件:前提是QQ邮箱里帐号设置要开启POP3/SMTP协议 */@Componentpublic class SimpleMailSender { @Value("${fromAddress}") private String fromAddress; @Value("${emailusername}") private String emailusername; @Value("${emailPass}") private String emailPass; @Value("${hosts}") private String hosts; public void main(String[] args) throws Exception { } public boolean sendMSG(String type, String emailTo, String UUID) { try { Properties prop = new Properties(); // 开启debug调试，以便在控制台查看 // prop.setProperty("mail.debug", "true"); // 设置邮件服务器主机名 prop.setProperty("mail.host", "smtp.qq.com"); // 发送服务器需要身份验证 prop.setProperty("mail.smtp.auth", "true"); // 发送邮件协议名称 prop.setProperty("mail.transport.protocol", "smtp"); // 开启SSL加密，否则会失败 MailSSLSocketFactory sf = new MailSSLSocketFactory(); sf.setTrustAllHosts(true); prop.put("mail.smtp.ssl.enable", "true"); prop.put("mail.smtp.ssl.socketFactory", sf); // 创建session Session session = Session.getInstance(prop); // 通过session得到transport对象 Transport ts = session.getTransport(); // 连接邮件服务器：邮箱类型，帐号，授权码代替密码（更安全） System.out.println("emailusername=" + emailusername); ts.connect(hosts, emailusername, emailPass);// 后面的字符是授权码 // 创建邮件 Message message = createSimpleMail(type, emailTo, UUID, session); // 发送邮件 ts.sendMessage(message, message.getAllRecipients()); ts.close(); return true; } catch (Exception e) { return false; } } /** * @Method: createSimpleMail * @Description: 创建一封只包含文本的邮件 */ public MimeMessage createSimpleMail(String type, String emailTo, String UUID, Session session) throws Exception { // 创建邮件对象 MimeMessage message = new MimeMessage(session); // 指明邮件的发件人 message.setFrom(new InternetAddress(fromAddress)); // 指明邮件的收件人 message.setRecipient(Message.RecipientType.TO, new InternetAddress(emailTo)); // 邮件的标题 message.setSubject("修改密码"); // 邮件的文本内容 if ("create".equals(type)) message.setContent("尊敬的用户,您正在尝试注册帐号,请将后面内容复制到验证栏:" + UUID + "n如不是本人操作,请勿将验证码发送给他人!!!", "text/html;charset=UTF-8"); else if ("reset".equals(type)) message.setContent("尊敬的用户,您正在尝试修改密码,请将后面内容复制到修改密码处:" + UUID + "n如不是本人操作,请勿将验证码发送给他人!!!", "text/html;charset=UTF-8"); // 返回创建好的邮件对象 return message; }}
收到的邮件如下
