java代码实现邮件发送.doc

1、在我的资源库里面下载支持的jar包，下载地址：http://download.csdn.net/detail/harderxin/4451541
2、测试代码：
packagecom.email.test;

importjava.util.Properties;
importjavax.mail.Address;
importjavax.mail.Message;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;

publicclassTestEmail{
publicvoidSendEmailTest(){
Propertiesprops=newProperties();
props.put("mail.smtp.host","smtp.qq.com");
props.put("mail.smtp.auth","true");//允许smtp校验
SessionsendMailSession=Session.getInstance(props,null);

try{
Transporttransport=sendMailSession.getTransport("smtp");
//连接你的QQ，注意用户名和密码必须填写正确，否则权限得不到
transport.connect("smtp.qq.com","[e-mail]","****");
MessagenewMessage=newMimeMessage(sendMailSession);

//设置mail主题
Stringmail_subject="更改邮件发送人测试";
newMessage.setSubject(mail_subject);

//设置发信人地址
StringstrFrom="[e-mail]";
strFrom=newString(strFrom.getBytes(),"iso-8859-1");
newMessage.setFrom(newInternetAddress(strFrom));
//AddressaddressFrom[]={new（参考：http://www.linbayan8.com）
//InternetAddress("[e-mail]"),new
//InternetAddress("[e-mail]")};
//改变发件人地址
//newMessage.addFrom(addressFrom);
//设置收件人地址
AddressaddressTo[]={newInternetAddress("[e-mail]")};
newMessage.setRecipients(Message.RecipientType.TO,addressTo);

//设置mail正文
newMessage.setSentDate(newjava.util.Date());
Stringmail_text="java实现邮件发送！";
newMessage.setText(mail_text);

newMessage.saveChanges();//保存发送信息
transport.sendMessage(newMessage,newMessage
.getRecipients(Message.RecipientType.TO));//发送邮件

transport.close();
//Transport.send(newMessage);
System.out.println("发送成功!");
}catch(Exceptione){
System.out.println("发送失败！");
System.out.println(e);
}

}
