Java mail email sending instance

The project uses one requirement. After completing a specific task, you need to automatically send an email to the customer. It is relatively simple to read javamail... don't worry, you know, then start to write a simple entry, first Baidu find

Mail. jar, commons-email-X.X.jar, activation. Jar these three jar, put into the project

Write a Simple Mail object first

Package COM. shadow. MVC. VO; import Java. io. serializable;/*** mail attribute entity ** @ author shadow **/@ suppresswarnings ("serial") public class mail implements serializable {public static final string encodeing = "UTF-8 "; private string host; // server address private string sender; // sender's email address private string Explorer; // recipient's email address private string name; // sender's nickname private string username; // account private string password; // password private string subject; // topic private string message; // information (HTML supported) Public String gethost () {return host ;} public void sethost (string host) {This. host = host;} Public String getsender () {return sender;} public void setsender (string sender) {This. sender = sender;} Public String getreceiver () {return receiver;} public void setreceiver (string receiver) {This. extends ER = extends er;} Public String getname () {return name;} public void setname (string name) {This. name = Name;} Public String GetUserName () {return username;} public void setusername (string username) {This. username = username;} Public String GetPassword () {return password;} public void setpassword (string password) {This. password = password;} Public String getsubject () {return subject;} public void setsubject (string subject) {This. subject = subject;} Public String getmessage () {return message;} public void setmessage (string message) {This. message = message ;}}

Then write a tool class.

Package COM. shadow. extras. util; import Org. apache. commons. mail. emailexception; import Org. apache. commons. mail. htmlemail; import Org. apache. log4j. logger; import COM. shadow. MVC. VO. mail;/*** mail sending tool implementation class ** @ author shadow * @ create 2013/07/12 */public class mailutil {protected final logger = logger. getlogger (getclass (); Public Boolean send (mail) {// send emailhtmlemail email = new htmlemail (); try {// The Name Of The SMTP sending server is as follows: 163: "smtp.163.com" email. sethostname (mail. gethost (); // set email for the character set. setcharset (mail. encodeing); // email address of the recipient. addto (mail. getcycler (); // sender's email. setfrom (mail. getsender (), mail. getname (); // If you need authentication information, set authentication: User Name-password. The registration name and password email of the sender on the email server. setauthentication (mail. getUserName (), mail. getPassword (); // The subject email to be sent. setsubject (mail. getsubject (); // the message to be sent. Because htmlemail is used, you can use the HTML Tag email in the mail content. setmsg (mail. getmessage (); // send an email. send (); If (logger. isdebugenabled () {logger. debug (mail. getsender () + "send email to" + mail. getcycler ();} return true;} catch (emailexception e) {e. printstacktrace (); logger.info (mail. getsender () + "send email to" + mail. getcycler () + "failed"); Return false ;}}}

Finally, write a main method for testing.

Public static void main (string [] ARGs) {mail = new mail (); mail. sethost ("smtp.163.com"); // set up the email server. If you do not need 163 email, find the relevant mail. setsender ("shadowsick@163.com"); mail. setcycler ("shadowsick@163.com"); // recipient mail. setusername ("shadowsick@163.com"); // login account, is generally the same as the mailbox name mail. setpassword ("XXXXX"); // mail the sender's email logon password. setsubject ("aaaaaaaaa"); mail. setmessage ("bbbbbbbbbbbbbbbbbbb"); New mailutil (). send (Mail );}

Finally, let's look at the effect.
