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");
	}
	
}
