2. Service class (Simplemailsender)

Package Sendemail.email;import Java.util.date;import Java.util.properties;import javax.mail.address;import    Javax.mail.message;import Javax.mail.session;import Javax.mail.BodyPart;    Import javax.mail.MessagingException;    Import Javax.mail.Multipart;    Import Javax.mail.Transport;    Import javax.mail.internet.InternetAddress;    Import Javax.mail.internet.MimeBodyPart;    Import Javax.mail.internet.MimeMessage;  Import Javax.mail.internet.MimeMultipart; /** * Send message format settings * @author Administrator * */public class Simplemailsender {/** * in (text) (textbox) Send mail * @param mailin FO message to be sent */public boolean sendtextmail (Mailsenderinfo mailinfo) {Properties pro = Mailinfo.getproperties ();   Session sendmailsession = session.getinstance (pro);          try {//Create a mail message based on session MailMessage = new MimeMessage (sendmailsession);          Create mail Sender address from = new InternetAddress (mailinfo.getfromaddress ()); Set the sender of the mail message mailmessage.sEtfrom (from);          Create the recipient address of the message, and set it to the mail message in addr to = new InternetAddress (mailinfo.gettoaddress ());          Mailmessage.setrecipient (message.recipienttype.to,to);          Set the subject of the mail message Mailmessage.setsubject (Mailinfo.getsubject ());          Sets the time mailmessage.setsentdate the mail message is sent (new Date ());          Set the main content of the mail message String mailcontent = Mailinfo.getcontent ();          Mailmessage.settext (mailcontent);      Send mail mailmessage.savechanges ();      Transport Transport = Sendmailsession.gettransport ("SMTP");      Transport.connect (Mailinfo.getmailserverhost (), Mailinfo.getusername (), Mailinfo.getpasswrod ());         Transport.sendmessage (Mailmessage,mailmessage.getallrecipients ());                return true;          } catch (Messagingexception ex) {ex.printstacktrace ();   } return false;   /** * Send mail in HTML format * @param mailinfo message message to be sent */public static Boolean Sendhtmlmail (Mailsenderinfo mailinfo) {  Properties Pro = Mailinfo.getproperties ();     Constructs a session session Sendmailsession = Session.getdefaultinstance (pro) for sending mail based on mail session properties and Password verifier;   try {//Create a mail message based on session MailMessage = new MimeMessage (sendmailsession);   Create mail Sender address from = new InternetAddress (mailinfo.getfromaddress ());     Set the sender Mailmessage.setfrom (from) of the mail message;     Create the recipient address of the message, and set it to the mail message in addr to = new InternetAddress (mailinfo.gettoaddress ());     The Message.RecipientType.TO property indicates the recipient's type is to Mailmessage.setrecipient (message.recipienttype.to,to);     Set the subject of the mail message Mailmessage.setsubject (Mailinfo.getsubject ());     Sets the time mailmessage.setsentdate the mail message is sent (new Date ());     The Minimultipart class is a container class that contains objects of type MimeBodyPart Multipart Mainpart = new Mimemultipart ();     Create a mimebodypart bodypart html = new MimeBodyPart () that contains HTML content; Set HTML content html.setcontent (Mailinfo.getcontent (), "text/html;     Charset=utf-8 ");     Mainpart.addbodypart (HTML); Will MinimultipartThe object is set to the message content mailmessage.setcontent (Mainpart);     Send mail mailmessage.savechanges ();     Transport Transport = Sendmailsession.gettransport ("SMTP");     Transport.connect (Mailinfo.getmailserverhost (), Mailinfo.getusername (), Mailinfo.getpasswrod ());  Transport.sendmessage (Mailmessage,mailmessage.getallrecipients ());     return true;     } catch (Messagingexception ex) {ex.printstacktrace ();    } return false; }    }

3. Test Class (MailTest)

Package sendemail.email;/** * Test class * @author Administrator * */public class MailTest {public static void main (string[] args {//Set mail try {mailsenderinfo maininfo = new Mailsenderinfo (); Maininfo.setmailserverhost ("smtp.163.com"); Maininfo.setvalidate (True); Maininfo.setusername ("**************"); Maininfo.setpasswrod ("********"); Maininfo.setfromaddress ("********");    Maininfo.settoaddress ("********");    Maininfo.setsubject ("Lalalala"); Maininfo.setcontent ("----");   Simplemailsender.sendhtmlmail (maininfo);//Send stylistic format   } catch (Exception e) {e.printstacktrace ();}}}

Attention:

Maininfo.setpasswrod ("********"); is not the password to login 163 mailbox, is 163 mailbox authorization code.
