Java instance code for sending mail (portable) _java

Take a Web project as an example, the code is portable

First you import the Mail.jar package, and then you create your own class

1:htmlsender class

Copy Code code as follows:

Package com.txq.mail;

Import java.util.Properties;

Import Javax.mail.Message;
Import javax.mail.MessagingException;
Import javax.mail.NoSuchProviderException;
Import javax.mail.Session;
Import Javax.mail.Transport;
Import javax.mail.internet.AddressException;
Import javax.mail.internet.InternetAddress;
Import Javax.mail.internet.MimeMessage;
Import Javax.mail.internet.MimeMultipart;
Import javax.mail.internet.MimeUtility;

/**
*
* @author Administrator
*
*/
public class Htmlsender {
Private MimeMessage message;
Private Properties props;
Private session session;
Private String name = "";
Private String Password = "";

Public Htmlsender (String host,string name,string password)
{
THIS.name = name;
This.password = password;
Props = System.getproperties ();

Props.put ("Mail.smtp.host", host);
Props.put ("Mail.smtp.auth", "true");
Myauthenticator auth = new Myauthenticator (Name,password);
Session = Session.getdefaultinstance (Props,auth);

message = new MimeMessage (session);
New Mimemultipart ();
}

public void Setfrom (String from)
{
Try
{
Message.setfrom (New InternetAddress (from));
}
catch (Addressexception e)
{
E.printstacktrace ();
}
catch (Messagingexception e)
{
E.printstacktrace ();
}
}

public void Setto (String to)
{
Try
{
Message.setrecipients (To) (Message.recipienttype.to,internetaddress.parse);
}
catch (Addressexception e)
{
E.printstacktrace ();
}
catch (Messagingexception e)
{
E.printstacktrace ();
}
}

public void Setsubject (String subject)
{
Try
{
Message.setsubject (subject);
}
catch (Exception e)
{
E.printstacktrace ();
}
}

public void Setcontect (String content)
{
Try
{
Message.setcontent (Content, "text/html;charset=utf-8");
}
catch (Exception e)
{
E.printstacktrace ();
}
}

public boolean Send ()
{
Try
{
Transport transport = Session.gettransport ("SMTP");
Transport.connect ((String) props.get ("Mail.smtp.host"), Name,password);
Transport.sendmessage (Message, message.getrecipients (Message.RecipientType.TO));
Transport.close ();
return true;
}
catch (Nosuchproviderexception e)
{
E.printstacktrace ();
return false;
}
catch (Messagingexception e)
{
E.printstacktrace ();
return false;
}
}
}

2:myauthenticator class

Copy Code code as follows:

Package com.txq.mail;

Import Javax.mail.Authenticator;
Import javax.mail.PasswordAuthentication;


public class Myauthenticator extends authenticator{
String name;
String password;
Public Myauthenticator (String name,string pasword)
{
THIS.name = name;
This.password = Pasword;
Getpasswordauthentication ();
}
Protected Passwordauthentication getpasswordauthentication ()
{
return new Passwordauthentication (Name,password);
}
}

3:mailaction class

Copy Code code as follows:

Package com.txq.action;

Import Java.io.PrintWriter;

Import Com.opensymphony.xwork2.ActionSupport;
Import Com.txq.mail.HTMLSender;

public class Mailaction extends Actionsupport {
Private String Email;
Public String SendEmail () {
Agent Host-Sina
String host = "smtp.sina.cn";
Account number-Sina account
String name = "Followmusic";
Password-Sina password
String password = "Followmusic";
Create a Send mail object
Htmlsender mail = new Htmlsender (Host,name,password);
Email account
Mail.setfrom ("followmusic@sina.cn");
e-Mail Billing Account
Mail.setto ("youxiangzhanghe@qq.com");
Message subject
Mail.setsubject ("Amoy interest");
Message content
Mail.setcontect ("Your friend invites you to Amoy interest ~");

if (Mail.send ())
{
return SUCCESS;
}
Else
{
return "error";
}
}
Public String Getemail () {
return email;
}
public void Setemail (String email) {
This.email = email;
}
}
