1.QQ邮箱设置

　　1.1 进去QQ邮箱-->设置-->账号-->进行设置如下图

2.foxmail设置(由于我要利用它收邮件)

　　2.1 参照官方的设置即可 http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=371

　　ps：填写的邮箱密码是独立密码:需要注意的就是SSL链接要勾选;smtp端口是465

3.Java中代码配置(导入javax.mail.jar，如果jdk低于6，则需导入javax.activation.jar(用来出来MIME类型内容))

　　3.1 发送邮件配置代码

//发送邮箱验证        try {            Properties prop = new Properties();            prop.setProperty("mail.transport.protocol", "smtp");            prop.setProperty("mail.smtp.host", "smtp.qq.com");            prop.setProperty("mail.smtp.auth", "true");            prop.put("mail.smtp.port","465");       prop.put("mail.smtp.ssl.enable", "true");           prop.setProperty("mail.debug", "true");            Authenticator authenticator = new EmailAuthenticator("1274444444@qq.com", "密码（此处密码为从QQ邮箱的【设置】->【账户】->【POP3/IMAP/SMTP...】中获取的授权码）");            //创建会话            Session session = Session.getInstance(prop,authenticator);            //填写信封写信            Message msg = new MimeMessage(session);            msg.setFrom(new InternetAddress("1271099894@qq.com"));            msg.setRecipient(RecipientType.TO, new InternetAddress(user.getEmail()));            msg.setSubject(user.getUsername()+"激活邮箱!");            msg.setContent(user.getUsername()+",你好请到这个地址激活你的账号：http://www.estore.com/ActiveServlet?activecode="+user.getActivecode()                           ,"text/html;charset=utf8");            //验证用户名密码发送邮件            Transport transport = session.getTransport();            //transport.connect("1274444444@qq.com","qq邮箱验证码");            transport.send(msg);            transport.close();        }

　　3.2辅助类

     public class EmailAuthenticatorextends Authenticator {        String userName = null;        String password = null;        public PopAuthenticator() {        }        public PopAuthenticator(String username, String password) {            this.userName = username;            this.password = password;        }        protected PasswordAuthentication getPasswordAuthentication() {            return new PasswordAuthentication(userName, password);        }     }
