使用java mail的网易smtp协议 发送邮件

package com.enation.newtest;

import java.security.GeneralSecurityException;
import java.util.Properties;

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

public class TestMail {

    public static void main(String[] args) throws MessagingException, GeneralSecurityException {
        Properties props = new Properties();

        // 开启debug调试
        props.setProperty("mail.debug", "true");
        // 发送服务器需要身份验证
        props.setProperty("mail.smtp.auth", "true");
        // 设置邮件服务器主机名
        props.setProperty("mail.host", "smtp.163.com");
        // 发送邮件协议名称
        props.setProperty("mail.transport.protocol", "smtp");

        Session session = Session.getInstance(props);

        Message msg = new MimeMessage(session);
        msg.setSubject("seenews 错误");
        StringBuilder builder = new StringBuilder();
        builder.append("url = " + "http://blog.csdn.net/never_cxb/article/details/50524571");
        builder.append("\n页面爬虫错误");
        builder.append("\n时间 2016 ");
        msg.setText(builder.toString());
        msg.setFrom(new InternetAddress("**发送人的邮箱地址**"));

        Transport transport = session.getTransport();
        transport.connect("smtp.163.com", "**发送人的邮箱地址**", "**你的邮箱密码或者授权码**");

        transport.sendMessage(msg, new Address[] { new InternetAddress("**接收人的邮箱地址**") });
        transport.close();
    }

}

这个代码使用的是网易

smtp.163.com服务，测试前把自己的账号开通smtp服务即可
