之前学习的java后台实现的邮件的简单代码与大家分享一下，欢迎拍砖！

也没有时间仔细整理，大概使用到的包包括：

代码示例如下：

package com.mail.impl;

import java.util.ArrayList;
import java.util.Properties;
import java.util.StringTokenizer;

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