2.发送邮件代码

package com.yjq.email;

import java.util.Date;
import java.util.Properties;

import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendEmail {

    //发件人的邮箱和密码
    public static String myEmailAccount = "156xxx@163.com";
    public static String myEmailPassword = "123456";
    
    //发件人的SMTP服务器地址
    public static String myEmailSMTPHost = "smtp.163.com";
    
    //收件人邮箱
    public static String receiveEmailAccount = "14xxx@qq.com";
    
    public static void main(String[] args) 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.host", myEmailSMTPHost);  //发件人的邮箱的SMTP服务器地址
        props.setProperty("mail.smtp.auth", "true");  //请求认证，参数名称与具体实现有关
        
        //2.根据配置创建会话对象，用于和邮件服务器交互
        Session session = Session.getDefaultInstance(props);
        session.setDebug(true);  //设置debug模式，可以查看详细的发送日志
        
        //3.创建一封邮件
        MimeMessage message = createMimeMessage(session, myEmailAccount, receiveEmailAccount);
        
        //4.根据Session获取邮件传输对象
        Transport transport = session.getTransport();
        
        //5.使用邮箱帐号和密码连接邮件服务器
        transport.connect(myEmailAccount, myEmailPassword);
        
        //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());
        
        System.err.println("发送邮件成功！");
        
        //7.关闭连接
        transport.close();
        
    }
