1. 邮箱信息实体类

package cn.bitqian.mail.test;

/**
 * 邮件内容实体类
 * @author echo lovely
 * @date 2020/9/18 15:47
 */
public class MailInfo {

  // 发件人账户
  private String sendEmailAccount;

  // 发件人密码
  private String sendEmailPassword;

  // 收件人账户
  private String receiveMailAccount;

  // 发送人姓名
  private String sendPersonName;

  // 收件人姓名
  private String receivePersonName;

  // 邮件标题
  private String mailTitle;

  // 邮件正文
  private String mailContent;

  public MailInfo(String sendEmailAccount, String sendEmailPassword, String receiveMailAccount,
          String sendPersonName, String receivePersonName,
          String mailTitle, String mailContent) {
    this.sendEmailAccount = sendEmailAccount;
    this.sendEmailPassword = sendEmailPassword;
    this.receiveMailAccount = receiveMailAccount;
    this.sendPersonName = sendPersonName;
    this.receivePersonName = receivePersonName;
    this.mailTitle = mailTitle;
    this.mailContent = mailContent;
  }

  public String getSendEmailAccount() {
    return sendEmailAccount;
  }

  public void setSendEmailAccount(String sendEmailAccount) {
    this.sendEmailAccount = sendEmailAccount;
  }

  public String getSendEmailPassword() {
    return sendEmailPassword;
  }

  public void setSendEmailPassword(String sendEmailPassword) {
    this.sendEmailPassword = sendEmailPassword;
  }

  public String getReceiveMailAccount() {
    return receiveMailAccount;
  }

  public void setReceiveMailAccount(String receiveMailAccount) {
    this.receiveMailAccount = receiveMailAccount;
  }

  public String getMailTitle() {
    return mailTitle;
  }

  public void setMailTitle(String mailTitle) {
    this.mailTitle = mailTitle;
  }

  public String getMailContent() {
    return mailContent;
  }

  public void setMailContent(String mailContent) {
    this.mailContent = mailContent;
  }

  public String getSendPersonName() {
    return sendPersonName;
  }

  public void setSendPersonName(String sendPersonName) {
    this.sendPersonName = sendPersonName;
  }

  public String getReceivePersonName() {
    return receivePersonName;
  }

  public void setReceivePersonName(String receivePersonName) {
    this.receivePersonName = receivePersonName;
  }
}

2. jar包依赖

 <dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
 </dependency>

 <!-- mail dependency -->
 <dependency>
  <groupId>com.sun.mail</groupId>
  <artifactId>javax.mail</artifactId>
  <version>1.6.2</version>
 </dependency>

3. 发送邮箱实现

注意：

1. 更改下面的属性，与实体类对应

代码实现

package cn.bitqian.mail.test;

import org.junit.Test;

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Date;
import java.util.Properties;

/**
 * 邮件发送工具类
 * @author echo lovely
 * @date 2020/9/18 15:54
 */
public class MailSendUtils {

  // 邮箱smtp协议 这里是使用阿里云的
  public static final String myEmailSMTPHost = "smtpdm.aliyun.com";

  @Test
  public void test() {
    MailInfo mailInfo = new MailInfo("控制台所绑定的邮箱账户名",
        "绑定账户邮箱密码",
        "收件人邮箱名", "发件人姓名",
        "收件人姓名", "邮箱标题", "邮箱内容");
    try {
      sendEmail(mailInfo);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

  public void sendEmail(MailInfo mailInfo) throws Exception {

    // 1. 创建参数配置, 用于连接邮件服务器的参数配置
    Properties props = new Properties();          // 参数配置
    props.setProperty("mail.transport.protocol", "smtp");  // 使用的协议（JavaMail规范要求）
    props.setProperty("mail.smtp.host", myEmailSMTPHost);  // 发件人的邮箱的 SMTP 服务器地址
    props.setProperty("mail.smtp.auth", "true");      // 需要请求认证

    // 2. 根据配置创建会话对象, 用于和邮件服务器交互
    Session session = Session.getInstance(props);
    session.setDebug(true);                 // 设置为debug模式, 可以查看详细的发送 log

    // 3. 创建一封邮件
    MimeMessage message = new MailSendUtils().createMimeMessage(session, mailInfo);

    // 4. 根据 Session 获取邮件传输对象
    Transport transport = session.getTransport();

    // 5. 使用 邮箱账号 和 密码 连接邮件服务器, 这里认证的邮箱必须与 message 中的发件人邮箱一致, 否则报错
    transport.connect(mailInfo.getSendEmailAccount(), mailInfo.getSendEmailPassword());

    // 6. 发送邮件, 发到所有的收件地址, message.getAllRecipients() 获取到的是在创建邮件对象时添加的所有收件人, 抄送人, 密送人
    transport.sendMessage(message, message.getAllRecipients());

    // 7. 关闭连接
    transport.close();
  }

  public MimeMessage createMimeMessage(Session session, MailInfo mailInfo) throws Exception {
    // 1. 创建一封邮件
    MimeMessage message = new MimeMessage(session);

    // 2. From: 发件人（昵称有广告嫌疑，避免被邮件服务器误认为是滥发广告以至返回失败，请修改昵称）
    message.setFrom(new InternetAddress(mailInfo.getSendEmailAccount(), mailInfo.getSendPersonName(), "UTF-8"));

    // 3. To: 收件人（可以增加多个收件人、抄送、密送）
    message.setRecipient(MimeMessage.RecipientType.TO,
        new InternetAddress(mailInfo.getReceiveMailAccount(), mailInfo.getReceivePersonName(), "UTF-8"));

    // 4. Subject: 邮件主题（标题有广告嫌疑，避免被邮件服务器误认为是滥发广告以至返回失败，请修改标题）
    message.setSubject(mailInfo.getMailTitle(), "UTF-8");

    // 5. Content: 邮件正文（可以使用html标签）（内容有广告嫌疑，避免被邮件服务器误认为是滥发广告以至返回失败，请修改发送内容）
    message.setContent(mailInfo.getMailContent(), "text/html;charset=UTF-8");

    // 6. 设置发件时间
    message.setSentDate(new Date());

    // 7. 保存设置
    message.saveChanges();

    return message;
  }

}
