1、Demo1 发送文本内容邮件

源码：

package com.peng.sun;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class Lession1 {

String host = "";

String user = "";

String password = "";

public void setHost(String host) {

this.host = host;

}

public void setAccount(String user, String password) {

this.user = user;

this.password = password;

}

public void send(String from, String to, String subject, String content) {

Properties props = new Properties();

props.put("mail.smtp.host", host); // 指定SMTP服务器

props.put("mail.smtp.auth", "true"); // 指定是否需要SMTP验证

try {

Session mailSession = Session.getDefaultInstance(props);

Message message = new MimeMessage(mailSession);

message.setFrom(new InternetAddress(from)); // 发件人

message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // 收件人

message.setSubject(subject); // 邮件主题

message.setText(content); // 邮件内容

message.saveChanges();

Transport transport = mailSession.getTransport("smtp");

transport.connect(host, user, password);

transport.sendMessage(message, message.getAllRecipients());

transport.close();

} catch(Exception e) {

System.out.println(e);

}

public static void main(String[] args) {

Lession1 sm = new Lession1();

sm.setHost("smtp.qiye.163.com"); // 指定要使用的邮件服务器

sm.setAccount("sunpeng@cfc-si.com", "*********"); // 指定帐号和密码

* @param String 发件人的地址

* @param String 收件人地址

* @param String 邮件标题

* @param String 邮件正文

sm.send("sunpeng@cfc-si.com", "sunpeng2@cfc-si.com", "标题", "HelloWold!");

}

2、Demo2 发送HTML内容邮件

//主要利用message.setContent(content, "text/html;charset=utf-8");来实现发送html内容的邮件

源码如下：
