使用java实现简单的邮件发送

package com.wxt;

import com.sun.mail.util.MailSSLSocketFactory;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class MailDemo01 {
    public static void main(String[] args) throws Exception {
        Properties prop=new Properties();
        prop.setProperty("mail.host","smtp.qq.com");///设置QQ邮件服务器
        prop.setProperty("mail.transport.protocol","smtp");///邮件发送协议
        prop.setProperty("mail.smtp.auth","true");//需要验证用户密码
        //QQ邮箱需要设置SSL加密
        MailSSLSocketFactory sf=new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);
        prop.put("mail.smtp.ssl.enable","true");
        prop.put("mail.smtp.ssl.socketFactory",sf);

        //使用javaMail发送邮件的5个步骤
        //1.创建定义整个应用程序所需要的环境信息的session对象
        Session session=Session.getDefaultInstance(prop, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("1043001092@qq.com","rskbkghnaooybcgc");
            }
        });
        //开启session的debug模式，这样可以查看到程序发送Email的运行状态
        session.setDebug(true);
        //2.通过session得到transport对象
        Transport ts=session.getTransport();
        //3.使用邮箱的用户名和授权码连上邮件服务器
        ts.connect("smtp.qq.com","1043001092@qq.com","rskbkghnaooybcgc");
        //4.创建邮件：写文件
        //注意需要传递session
        MimeMessage message=new MimeMessage(session);
        //指明邮件的发件人
        message.setFrom(new InternetAddress("1043001092@qq.com"));
        //指明邮件的收件人
        message.setRecipient(Message.RecipientType.TO,new InternetAddress("1043001092@qq.com"));
        //邮件标题
        message.setSubject("通过java发送邮件");
        //邮件的文本内容
        message.setContent("这是第一个java发送的邮件","text/html;charset=UTF-8");
        //5.发送邮件
        ts.sendMessage(message,message.getAllRecipients());

        //6.关闭连接
        ts.close();

    }
