// 连接协议

} /**

String receiveUser){
try {
// 发件人
InternetAddress from = new InternetAddress(FROMADDRESS);//发送人地址
message.setFrom(from);
// 收件人
InternetAddress to = new InternetAddress(receiveUser);

// 邮件标题
message.setSubject(headName);
String content = sendHtml.toString();
// 邮件内容,也可以使纯文本"text/plain"
message.setContent(content, "text/html;charset=UTF-8");
message.setSentDate(new Date());
message.saveChanges();
Transport transport = s.getTransport("smtp");
//这种方式应用于163网易邮箱和QQ邮箱,最后一个参数是授权码,网易的授权码可以自动设置,而QQ邮箱的授权码需通过短信才可收到
// transport.connect(FROMADDRESS,"25660663abc");
// transport.connect(FROMADDRESS,"yigoehcqlbxkhfid");
//QQ企业邮箱,新浪邮箱,由于企业QQ邮箱和新浪邮箱开通POP3/SMTP/IMAP服务时,不需要授权码
transport.connect(VALUE_SMTP, FROMADDRESS, SEND_PWD); // 发送
transport.sendMessage(message, message.getAllRecipients());
transport.close();
System.out.println("send success!");
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
} public static void main(String[] args) {
SendmailUtil se = new SendmailUtil();
se.doSendHtmlEmail("邮件标题1111", "邮件内容", "1481596361@qq.com");
}
}

以上例子是JavaMail实现邮箱之间发送邮件功能,需要注意的是发送邮箱是否需要授权码,需要授权码书写的方式和不需要授权码书写的方式不一致,主要区别在

transport.connect方法的参数,而接收邮件的邮箱却不规定,任意邮箱都可以。
需要导入一些包:

具体根据自身的情况进行导入,一般来说mail.jar或者javax.mail.jar和activation.jar需导入
