本文介绍了一个使用Java实现的邮件发送工具类，该工具通过SMTP协议利用163邮箱服务发送HTML格式的内容邮件。文中详细展示了如何配置邮件发送所需的属性，并通过Session和Transport实现了邮件的发送过程。

package com.li72.util;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;

public class EmailUtil {

public static void sendEmail(String email,String content)throws Exception{

  Properties pro=new Properties();
  pro.setProperty("mail.transport.protocol", "smtp");
// pro.setProperty("mail.host", "localhost");
  //pro.setProperty("mail.smtp.host", "smtp.163.com");
  pro.setProperty("mail.smtp.host","smtp.163.com");
  pro.setProperty("mail.smtp.auth", "true");
  Session session=Session.getDefaultInstance(pro, new Authenticator() {

   @Override
   protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication("15576967929@163.com","********");
   }
  });
  Message msg=new MimeMessage(session);

  msg.setFrom(InternetAddress.parse(MimeUtility.encodeText("15576967929@163.com"))[0]);
  msg.setSubject("主题");
  //msg.setRecipient(Message.RecipientType.TO, new InternetAddress(email));//收件人
  msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(email,false));//收件人
  //msg.setSentDate(new Date());
  msg.setContent(content, "text/html,utf-8");

  System.out.println(""+msg);
  Transport.send(msg);
}
