Java发送邮件工具类

大家好，又见面了，我是你们的朋友全栈君。

0. 准备工作

发送邮箱需要去开启 POP3/SMTP服务, 下面所有的密码都是授权码!!!!
qq邮箱的设置在QQ邮箱-->设置-->账号-->进行设置

1.一般邮箱

package com.zgd.bos.utils;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;
public class MailUtils { 

//邮件服务器主机地址
// private static String HOST="localhost";
private static String HOST="smtp.163.com";
//帐号
// private static String ACCOUNT = "test@zgd.com";
private static String ACCOUNT = "test@163.com";
//密码
// private static String PASSWORD = "123";
private static String PASSWORD = "zhang123";
/** * @param toUser 发送邮件给谁 * @param title 邮件的标题 * @param emailMsg 邮件信息 */
public static void sendMail(String toUser,String title, String emailMsg)throws AddressException, MessagingException { 

// 1.创建一个程序与邮件服务器会话对象 Session
Properties props = new Properties();
//设置发送的协议
props.setProperty("mail.transport.protocol", "SMTP");
//设置发送邮件的服务器
props.setProperty("mail.host", HOST);
props.setProperty("mail.smtp.auth", "true");// 指定验证为true
// 创建验证器
Authenticator auth = new Authenticator() { 

public PasswordAuthentication getPasswordAuthentication() { 

//设置发送人的帐号和密码 帐号 授权码
return new PasswordAuthentication(ACCOUNT, PASSWORD);
}
};
//会话
Session session = Session.getInstance(props, auth);
// 2.创建一个Message，它相当于是邮件内容
Message message = new MimeMessage(session);
//设置发送者
message.setFrom(new InternetAddress(ACCOUNT));
//设置发送方式与接收者
message.setRecipient(RecipientType.TO, new InternetAddress(toUser)); 
//设置邮件主题
message.setSubject(title);
// message.setText("这是一封激活邮件，请<a href='#'>点击</a>");
//设置邮件内容
message.setContent(emailMsg, "text/html;charset=utf-8");
// 3.创建 Transport用于将邮件发送
Transport.send(message);
}
public static void main(String[] args) throws AddressException, MessagingException { 

// MailUtils.sendMail("test@foxmail.com", "祝福邮件2", "哈哈哈");
MailUtils.sendMail("test@foxmail.com", "祝福邮件2", "这是正文");
}
}
