JAVA实现发送邮件

做项目时用到的小工具做个备份（

tips:

需要导入javax.mail 我使用了maven导入X
`

 <!-- JavaMail相关依赖 --><dependency><groupId>javax.mail</groupId><artifactId>javax.mail-api</artifactId><version>1.4.7</version></dependency><dependency><groupId>javax.activation</groupId><artifactId>activation</artifactId><version>1.1.1</version></dependency>

开启服务

总之全都开了不会错X

在这里插入图片描述

开启通过验证后得到授权码


package Util;import com.sun.mail.util.MailSSLSocketFactory;import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;import java.util.Properties;public class emailutil implements Runnable {private String email;// 收件人邮箱private String code;public emailutil(String email,String code) {this.email = email;this.code = code;}@Overridepublic void run() {// 1.创建连接对象javax.mail.Session// 2.创建邮件对象 javax.mail.Message// 3.发送一封激活邮件String from = "XXXXXXX@qq.com";// 发件人电子邮箱String host = "smtp.qq.com"; // 指定发送邮件的主机smtp.qq.com(QQ)|smtp.163.com(网易)Properties properties = System.getProperties();// 获取系统属性properties.setProperty("mail.smtp.host", host);// 设置邮件服务器properties.setProperty("mail.smtp.auth", "true");// 打开认证try {//QQ邮箱需要下面这段代码，163邮箱不需要MailSSLSocketFactory sf = new MailSSLSocketFactory();sf.setTrustAllHosts(true);properties.put("mail.smtp.ssl.enable", "true");properties.put("mail.smtp.ssl.socketFactory", sf);// 1.获取默认session对象Session session = Session.getDefaultInstance(properties, new Authenticator() {public javax.mail.PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication("XXXXX@qq.com",  "kXXXXX"); // 发件人邮箱账号、授权码}});// 2.创建邮件对象Message message = new MimeMessage(session);// 2.1设置发件人message.setFrom(new InternetAddress(from));// 2.2设置接收人message.addRecipient(Message.RecipientType.TO, new InternetAddress(email));// 2.3设置邮件主题message.setSubject("账号激活");// 2.4设置邮件内容String content = "<html><head></head><body>【内容】</body></html>";message.setContent(content, "text/html;charset=UTF-8");// 3.发送邮件Transport.send(message);System.out.println("邮件成功发送!");} catch (Exception e) {e.printStackTrace();}}
