Sending of Java and Spring Mail

Method One:

Java send e-mail: Here to send QQ Mail as an example:

Package test;

Import java.util.Properties;

Import Javax.mail.Authenticator;
Import Javax.mail.BodyPart;
Import Javax.mail.Message;
Import javax.mail.PasswordAuthentication;
Import javax.mail.Session;
Import Javax.mail.Transport;
Import javax.mail.internet.InternetAddress;
Import Javax.mail.internet.MimeBodyPart;
Import Javax.mail.internet.MimeMessage;
Import Javax.mail.internet.MimeMultipart;

public class Mysendemail {
public static void Main (string[] args) {
try {
String userName = "Sender qq number @qq.com";
String Password = "Sender's mailbox password";
String smtp_server = "smtp.qq.com"; QQ Mailbox mail server address
String from_mail_address = userName;
String to_mail_address = "The receiver QQ number @qq.com";
Authenticator auth = new Popupauthenticator (userName, password);
Properties Mailprops = new properties ();
Mailprops.put ("Mail.smtp.host", smtp_server);
Mailprops.put ("Mail.smtp.auth", "true");
Mailprops.put ("username", username);
Mailprops.put ("password", password);

Session mailsession = session.getdefaultinstance (Mailprops, auth);
Mailsession.setdebug (TRUE);
MimeMessage message = new MimeMessage (mailsession);
Message.setfrom (New InternetAddress (from_mail_address));
Message.setrecipient (Message.RecipientType.TO, New internetaddress (
to_mail_address));
Message.setsubject ("Mail testw");

Mimemultipart multi = new Mimemultipart ();
BodyPart Textbodypart = new MimeBodyPart ();
Textbodypart.settext ("Java e-mail test content w");
Textbodypart.setfilename ("37af4739a11fc9d6b311c712.jpg");
Textbodypart.setfilename ("E:\\api\\w3c.chm");

Multi.addbodypart (Textbodypart);
Message.setcontent (multi);
Message.savechanges ();
Transport.send (message);
} catch (Exception ex) {
System.err.println ("The reason the message failed to send is:" + ex.getmessage ());
SYSTEM.ERR.PRINTLN ("Specific cause of error");
Ex.printstacktrace (System.err);
}
}
}

Class Popupauthenticator extends Authenticator {
Private String username;
private String password;

Public Popupauthenticator (string username, string pwd) {
This.username = Username;
This.password = pwd;
}

Public Passwordauthentication getpasswordauthentication () {
return new Passwordauthentication (This.username, This.password);
}

Method Two: Use spring to provide the mail function, also to send QQ mailbox as an example:

　　Beans.xml File Code:

<?xml version= "1.0" encoding= "UTF-8"?>
<beans xmlns= "Http://www.springframework.org/schema/beans"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"
xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/ Spring-beans-2.5.xsd
HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP http://www.springframework.org/schema/aop/spring-aop-2.5.xsd ">
<!--Note: The parameters here (such as user name, password) are for the sender of the message--
<bean id= "MailSender" class= "Org.springframework.mail.javamail.JavaMailSenderImpl" >
<property name= "Host" >
<value>smtp.qq.com</value>
</property>
<property name= "Javamailproperties" >
<props>
<prop key= "Mail.smtp.auth" >true</prop>
<prop key= "Mail.smtp.timeout" >25000</prop>
</props>
</property>
<property name= "username" >
<value> Sender QQ No. @qq.com</value>
</property>
<property name= "Password" >
<value> Sender QQ Email password </value>
</property>

</bean>
</beans>

Java code to send the message:

Package test;

Import Java.util.UUID;

Import Org.springframework.context.ApplicationContext;
Import Org.springframework.context.support.ClassPathXmlApplicationContext;
Import Org.springframework.mail.SimpleMailMessage;
Import Org.springframework.mail.javamail.JavaMailSender;

public class SendMail {

Public ApplicationContext CTX = null;
Public SendMail () {
Get context
CTX = new Classpathxmlapplicationcontext ("Beans.xml");
}
public void Send () {
Get Javamailsender Bean
Javamailsender sender = (javamailsender) ctx.getbean ("MailSender");
Simplemailmessage mail = new Simplemailmessage (); <span style= "COLOR: #ff0000" > Note Simplemailmessage can only be used to send messages in text format </SPAN>


try {
Mail.setto ("Recipient @qq.com");//Recipient
Mail.setfrom ("sender @qq.com");//sender, here can also be another email alias, not with the username in the XML consistent
Mail.setsubject ("Spring Mail test!"); /Theme
Mail.settext ("Springmail simple send test, with random verification code:" +uuid.randomuuid (). toString (). substring (0, 6));//message content

Sender.send (mail);
} catch (Exception e) {
E.printstacktrace ();
}
}

public static void Main (string[] args) {
for (int i=0;i<100;i++) {

SendMail SendMail = new SendMail ();
Sendmail.send ();
SYSTEM.OUT.PRINTLN ("Send complete ...");

}

}
}

Complete....
