How Java uses javamail to send mail _java

This example describes how Java uses JavaMail to send mail. Share to everyone for your reference, specific as follows:

Code one, Email_autherticator.java server authentication code

Import Javax.mail.Authenticator;
Import javax.mail.PasswordAuthentication;
public class Email_autherticator extends Authenticator {
  String username = "Username of your mailbox";
  String password = "Password for your mailbox";
  Public Email_autherticator () {
 super ();
  }
  Public Email_autherticator (String user,string pwd) {
 super ();
 Username = user;
 Password = pwd;
  }
  Public Passwordauthentication getpasswordauthentication () {return
 new Passwordauthentication (username, password);
  }

Code two, Mail.java code to send mail

Import Java.util.Date;
Import java.util.Properties;
Import javax.mail.Address;
Import Javax.mail.Authenticator;
Import Javax.mail.Message;
Import javax.mail.SendFailedException;
Import javax.mail.Session;
Import Javax.mail.Transport;
Import javax.mail.internet.InternetAddress;
Import Javax.mail.internet.MimeMessage;
  public class Mail {private String host = ' smtp.126.com ';
  Private String Mail_head_name = "This are head to this mail";
  Private String Mail_head_value = "This are head to this mail";
  Private String mail_to = "254173774@qq.com";
  Private String Mail_from = "hackboyo@126.com";
  Private String Mail_subject = "This are the subject of this Test mail";
  Private String Mail_body = "This is mail_body to this test mail";
  Private String personalname = "my Mail";  public void SendMail () throws sendfailedexception{try {properties props = new properties ()//Get System Environment authenticator
   Auth = new Email_autherticator ()//Mail Service user authentication Props.put ("Mail.smtp.host", host); Props. put ("Mail.smtp.auth", "true");
   System.out.println (props);
   Session session = Session.getdefaultinstance (Props,auth);
   Set session, and mail server to communicate mimemessage message = new MimeMessage (session); Message.setcontent ("Hello", "Text/plain");//Set Message Format message.setsubject (mail_subject);/Set message theme message.settext (mail _body);/Set the message content Message.setheader (Mail_head_name, mail_head_value);//Set the message title Message.setsentdate (new Date ());/
   Set the email send period address = new internetaddress (mail_from,personalname); Message.setfrom (address)//Set the Mail sender's addresses toaddress = new internetaddress (mail_to);/Set the address of the mail recipient Message.addrecip
   Ient (message.recipienttype.to,toaddress);
   SYSTEM.OUT.PRINTLN (message);
   Transport.send (message);
 System.out.println ("Send Mail ok!");
 catch (Exception e) {e.printstacktrace ();
  }//return Flag;

 }
}

Code three, Test.java test the code to send the message

public class Test {public
  static void Main (string[] args) {
 mail m = new Mail ();
 try {
   m.sendmail ();
 } catch (Exception e) {
 }
  }
}
