Java实现腾讯企业邮箱收发邮件

个人邮箱发邮件很容易，网上很多工具类，使用企业邮箱发邮件其实原理是一样的，主要是加上一个企业邮箱必备的SSL，开启安全协议。
直接上代码，如下

package com.xxxx.util.sendemail;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

import com.sun.mail.util.MailSSLSocketFactory;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.security.GeneralSecurityException;
import java.util.Date;
import java.util.Properties;

/**
 * 发邮件工具类
 */
public class MailUtils {

	private static String account = "sendmail@xxxx.cn";// 登录账户
	private static String password = "xxxxxx";// 登录密码
	private static String host = "smtp.exmail.qq.com";// 服务器地址
	private static String port = "465";// 端口
	private static String protocol = "smtp";// 协议

//初始化参数
	public static Session initProperties() {
		Properties properties = new Properties();
		properties.setProperty("mail.transport.protocol", protocol);
		properties.setProperty("mail.smtp.host", host);
		properties.setProperty("mail.smtp.port", port);
		// 使用smtp身份验证
		properties.put("mail.smtp.auth", "true");
		// 使用SSL,企业邮箱必需 start
		// 开启安全协议
		MailSSLSocketFactory mailSSLSocketFactory = null;
		try {
			mailSSLSocketFactory = new MailSSLSocketFactory();
			mailSSLSocketFactory.setTrustAllHosts(true);
		} catch (GeneralSecurityException e) {
			e.printStackTrace();
		}
		properties.put("mail.smtp.enable", "true");
		properties.put("mail.smtp.ssl.socketFactory", mailSSLSocketFactory);
		properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
		properties.put("mail.smtp.socketFactory.fallback", "false");
		properties.put("mail.smtp.socketFactory.port", port);
		Session session = Session.getDefaultInstance(properties, new Authenticator() {
			@Override
			protected PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication(account, password);
			}
		});
		// 使用SSL,企业邮箱必需 end
		// TODO 显示debug信息 正式环境注释掉
		session.setDebug(true);
		return session;
	}

//@param sender 发件人的姓名
//@param subject 邮件的主题
//@param content 邮件的内容
//@param receiverList 接收者的列表,多个接收者之间用","隔开
//@param fileSrc 附件地址
	public static int send(String sender, String subject, String content, String receiverList, String fileSrc) {
		try {
			Session session = initProperties();
			MimeMessage mimeMessage = new MimeMessage(session);
			mimeMessage.setFrom(new InternetAddress(account, sender));// 发件人,可以设置发件人的别名
			// 收件人,多人接收
			InternetAddress[] internetAddressTo = new InternetAddress().parse(receiverList);
			mimeMessage.setRecipients(Message.RecipientType.TO, internetAddressTo);
			// 主题
			mimeMessage.setSubject(subject);
			// 时间
			mimeMessage.setSentDate(new Date());
			// 容器类 附件
			MimeMultipart mimeMultipart = new MimeMultipart();
			// 可以包装文本,图片,附件
			MimeBodyPart bodyPart = new MimeBodyPart();
			// 设置内容
			bodyPart.setContent(content, "text/html; charset=UTF-8");
			mimeMultipart.addBodyPart(bodyPart);
			// 添加图片&附件
			bodyPart = new MimeBodyPart();
			bodyPart.attachFile(fileSrc);
			mimeMultipart.addBodyPart(bodyPart);
			mimeMessage.setContent(mimeMultipart);
			mimeMessage.saveChanges();
			Transport.send(mimeMessage);
			return 1;
		} catch (MessagingException e) {
			e.printStackTrace();
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		return  -1;
	}

	public static void main(String[] args) {
		send("乱码行空","主题聚会","内容周五晚上xxx餐厅不见不散","1111111@qq.com","D:\Desktop\feifei.jpg");
