Java使用JavaMail发送邮件的方法
本文实例讲述了Java使用JavaMail发送邮件的方法。分享给大家供大家参考，具体如下：
代码一、Email_Autherticator.java服务器验证代码
importjavax.mail.Authenticator;
importjavax.mail.PasswordAuthentication;
publicclassEmail_AutherticatorextendsAuthenticator{
Stringusername="你邮箱的用户名";
Stringpassword="你邮箱的密码";
publicEmail_Autherticator(){
super();
}
publicEmail_Autherticator(Stringuser,Stringpwd){
super();
username=user;
password=pwd;
}
publicPasswordAuthenticationgetPasswordAuthentication(){
returnnewPasswordAuthentication(username,password);
}
}
代码二、Mail.java发送邮件的代码
importjava.util.Date;
importjava.util.Properties;
importjavax.mail.Address;
importjavax.mail.Authenticator;
importjavax.mail.Message;
importjavax.mail.SendFailedException;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;
publicclassMail{
privateStringhost="smtp.126.com";
privateStringmail_head_name="thisisheadofthismail";
privateStringmail_head_value="thisisheadofthismail";
privateStringmail_to="254173774@qq.com";
privateStringmail_from="hackboyo@126.com";
privateStringmail_subject="thisisthesubjectofthistestmail";
privateStringmail_body="thisismail_bodyofthistestmail";
privateStringpersonalName="我的邮件";
publicvoidsendMail()throwsSendFailedException{
try{
Propertiesprops=newProperties();//获取系统环境
Authenticatorauth=newEmail_Autherticator();//进行邮件服务用户认证
props.put("mail.smtp.host",host);
props.put("mail.smtp.auth","true");
System.out.println(props);
Sessionsession=Session.getDefaultInstance(props,auth);
//设置session,和邮件服务器进行通讯
MimeMessagemessage=newMimeMessage(session);
message.setContent("Hello","text/plain");//设置邮件格式
message.setSubject(mail_subject);//设置邮件主题
message.setText(mail_body);//设置邮件内容
message.setHeader(mail_head_name,mail_head_value);//设置邮件标题
message.setSentDate(newDate());//设置邮件发送时期
Addressaddress=newInternetAddress(mail_from,personalName);
message.setFrom(address);//设置邮件发送者的地址
Addresstoaddress=newInternetAddress(mail_to);//设置邮件接收者的地址
message.addRecipient(Message.RecipientType.TO,toaddress);
System.out.println(message);
Transport.send(message);
System.out.println("SendMailOk!");
}catch(Exceptione){
e.printStackTrace();
}
//returnflag;
}
}
代码三、Test.java测试发送邮件的代码
publicclassTest{
publicstaticvoidmain(String[]args){
Mailm=newMail();
try{
m.sendMail();
}catch(Exceptione){
}
}
}
希望本文所述对大家Java程序设计有所帮助。
