Java实现邮箱发送功能实例(阿里云邮箱推送)

前言

绑定阿里云域名,创建域名账户,并配置解析域名账户,获得发送邮箱的权限,上限两百封,超出要¥…

阿里云邮件推送控制台

https://aliyun.com/product/directmail

申请邮箱并解析域名

https://yq.aliyun.com/articles/707997

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 reSWqZbVvqAYceiveMailAccount;

}

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

junit

junit

4.11

test

com.sun.mail

javax.mail

1.6.2

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.InSWqZbVvqAYternetAddress;

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;

}

}
