第二个类：SimpleMailSender.java

package com.util.mail;

import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;

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

/**
* 简单邮件（不带附件的邮件）发送器

public class SimpleMailSender  {
/**
  * 以文本格式发送邮件
  * @param mailInfo 待发送的邮件的信息

public boolean sendTextMail(MailSenderInfo mailInfo) {
  // 判断是否需要身份认证
  MyAuthenticator authenticator = null;
  Properties pro = mailInfo.getProperties();
  if (mailInfo.isValidate()) {
  // 如果需要身份认证，则创建一个密码验证器
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
  }
  // 根据邮件会话属性和密码验证器构造一个发送邮件的session
  Session sendMailSession = Session.getDefaultInstance(pro,authenticator);
  try {
  // 根据session创建一个邮件消息
  Message mailMessage = new MimeMessage(sendMailSession);
  // 创建邮件发送者地址
  Address from = new InternetAddress(mailInfo.getFromAddress());
  // 设置邮件消息的发送者
  mailMessage.setFrom(from);
  // 创建邮件的接收者地址，并设置到邮件消息中
  Address to = new InternetAddress(mailInfo.getToAddress());
  mailMessage.setRecipient(Message.RecipientType.TO,to);
  // 设置邮件消息的主题
  mailMessage.setSubject(mailInfo.getSubject());
  // 设置邮件消息发送的时间

  String mailContent = mailInfo.getContent();
  mailMessage.setText(mailContent);
  // 发送邮件
  Transport.send(mailMessage);
  return true;
  } catch (MessagingException ex) {
  ex.printStackTrace();
  }
  return false;
}

/**
  * 以HTML格式发送邮件
  * @param mailInfo 待发送的邮件信息
  */
public static boolean sendHtmlMail(MailSenderInfo mailInfo){
  // 判断是否需要身份认证
  MyAuthenticator authenticator = null;
  Properties pro = mailInfo.getProperties();

  // 创建邮件发送者地址

  // Message.RecipientType.TO属性表示接收者的类型为TO
  mailMessage.setRecipient(Message.RecipientType.TO,to);

  // MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
  Multipart mainPart = new MimeMultipart();
  // 创建一个包含HTML内容的MimeBodyPart

  // 设置HTML内容

  // 发送邮件
  Transport.send(mailMessage);
  return true;
  } catch (MessagingException ex) {
  ex.printStackTrace();
  }
  return false;
}
}

第三个类：MyAuthenticator.java

package com.util.mail;

import javax.mail.*;
 
public class MyAuthenticator extends Authenticator{
String userName=null;
String password=null;

public MyAuthenticator(){
}
public MyAuthenticator(String username, String password) {
this.userName = username;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName, password);
}
}


下面给出使用上面三个类的代码：


public static void main(String[] args){
         //这个类主要是设置邮件
  MailSenderInfo mailInfo = new MailSenderInfo();
  mailInfo.setMailServerHost("smtp.163.com");
  mailInfo.setMailServerPort("25");
  mailInfo.setValidate(true);
  mailInfo.setUserName("*****@163.com");
  mailInfo.setPassword("**********");//您的邮箱密码
  mailInfo.setFromAddress("*****@163.com");
  mailInfo.setToAddress("*****@163.com");
  mailInfo.setSubject("设置邮箱标题");
  mailInfo.setContent("设置邮箱内容");
         //这个类主要来发送邮件
  SimpleMailSender sms = new SimpleMailSender();
          sms.sendTextMail(mailInfo);//发送文体格式
          sms.sendHtmlMail(mailInfo);//发送html格式
}
