Java Send mail

There should be more than one way for Java to send mail

All I'm saying here is that I will.

First add two jar packages Mail.jar and Activation.jar

Then write yourself a mail class that includes methods such as sending

1  Public classMail {2     PrivateString subject;3     PrivateString from;4     Privatestring[] recipients;5     PrivateString message;6 7     Private Static FinalString smtp_host_name = "";//your SMTP server address8     Private Static FinalString smtp_auth_user = "";//SMTP User name9     Private Static FinalString smtp_auth_pwd = "";//password;Ten      One      Public voidSend ()throwsmessagingexception{ A         Booleandebug =false; -  -Properties props =NewProperties (); theProps.put ("Mail.smtp.host", smtp_host_name); -Props.put ("Mail.smtp.auth", "true"); -  -Session session = Session.getdefaultinstance (props,Newsmtpauthenticator ()); + session.setdebug (debug); -  +         //Create a message AMessage msg =NewMimeMessage (session); atMsg.setfrom (Newinternetaddress (from)); -  -internetaddress[] Addressto =NewInternetaddress[recipients.length]; -          for(inti = 0; i < recipients.length; i++) -         { -Addressto[i] =Newinternetaddress (Recipients[i]); in         } - msg.setrecipients (Message.RecipientType.TO, addressto); to  +Msg.setheader ("X-priority", "3");//1: Emergency 3: normal 5: Slow - Msg.setsubject (subject); theMsg.setcontent (Message, "Text/plain; Charset=utf-8 "); * transport.send (msg); $     }Panax Notoginseng      -     //to certify the sender, open the following comment the     Private classSmtpauthenticatorextendsJavax.mail.Authenticator +     { A  the          Publicpasswordauthentication getpasswordauthentication () +         { -String username =Smtp_auth_user; $String Password =smtp_auth_pwd; $             return Newpasswordauthentication (username, password); -         } -     } the      -      PublicString Getsubject () {Wuyi         returnsubject; the     } -  Wu  -      Public voidSetsubject (String subject) { About          This. Subject =subject; $     } -  -  -      PublicString Getfrom () { A         returnfrom ; +     } the  -  $      Public voidSetfrom (String from) { the          This. from =from ; the     } the  the  -      Publicstring[] Getrecipients () { in         returnrecipients; the     } the  About  the      Public voidsetrecipients (string[] recipients) { the          This. Recipients =recipients; the     } +  -  the      PublicString getMessage () {Bayi         returnmessage; the     } the  -  -      Public voidsetmessage (String message) { the          This. Message =message; the     } the  the  -  the}

Such references in other classes are possible:

Private Static voidsendrenew (String tomail,string message) {Mail mail=NewMail (); Mail.setfrom ("License Manager <[email protected]>");//Sending PartyMail.setrecipients (NewString[]{tomail});//receiver, you can have multipleMail.setsubject ("Renew now!!");        Mail.setmessage (message); Try{mail.send ();//Send}Catch(Exception e) {System.out.println ("Error report failure.\n" +e); }    }

That's fine, but if you're using myeclipse, sometimes this happens.

Java.lang.noclassdeffounderror:com/sun/mail/util/lineinputstream
Workaround:
Enter the installation directory of the MyEclipse
D:\Genuitec\Common\plugins\com.genuitec.eclipse.j2eedt.core_8.5.0.me201003231033\data\libraryset\ee_5

(The blue part differs slightly in different versions )
Can see the Javaee.jar package,

Use the compression software to open the package file, then go to the Javax folder, delete the mail directory and the activation folder

( that is, the MyEclipse also comes with such a feature pack, except that the method is inconsistent with the JDK's JavaMail package, which results in a report exception )
After you delete the code, you will not get an error when you run it.
