java实现基于SMTP发送邮件的方法
本文实例讲述了java实现基于SMTP发送邮件的方法。分享给大家供大家参考。具体实现方法如下：
importjava.util.Date;
importjava.util.Properties;
importjavax.mail.Authenticator;
importjavax.mail.Message;
importjavax.mail.PasswordAuthentication;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;
importorg.apache.log4j.Logger;
publicclassMailUtil{
privatestaticLoggerlogger=Logger.getLogger(MailUtil.class);
/**
*发送邮件
*
*@paramsmtp
*SMTP服务器
*@paramuser
*用户名
*@parampassword
*密码
*@paramsubject
*标题
*@paramcontent
*邮件内容
*@paramfrom
*发件人邮箱
*@paramto
*收件人邮箱
*/
publicstaticvoidsend(Stringsmtp,finalStringuser,
finalStringpassword,Stringsubject,Stringcontent,Stringfrom,
Stringto){
try{
Propertiesprops=newProperties();
props.put("mail.smtp.host",smtp);
props.put("mail.smtp.auth","true");
Sessionssn=Session.getInstance(props,newAuthenticator(){
@Override
protectedPasswordAuthenticationgetPasswordAuthentication(){
returnnewPasswordAuthentication(user,password);
}
});
MimeMessagemessage=newMimeMessage(ssn);
//由邮件会话新建一个消息对象
InternetAddressfromAddress=newInternetAddress(from);
//发件人的邮件地址
message.setFrom(fromAddress);
//设置发件人
InternetAddresstoAddress=newInternetAddress(to);
//收件人的邮件地址
message.addRecipient(Message.RecipientType.TO,toAddress);
//设置收件人
message.setSubject(subject);
//设置标题
message.setText(content);
//设置内容
message.setSentDate(newDate());
//设置发信时间
Transporttransport=ssn.getTransport("smtp");
transport.connect(smtp,user,password);
transport.sendMessage(message,message
.getRecipients(Message.RecipientType.TO));
//transport.send(message);
transport.close();
logger.info("邮件发送成功");
}catch(Exceptione){
logger.warn("邮件发送失败",e);
}
}
}
希望本文所述对大家的java程序设计有所帮助。
