JavaMail (ii): Using JavaMail to send complex messages

Previous article we learned to use JavaMail to send Simple mail, this article we use JavaMail send a slightly more complex message (including text, pictures, attachments). Only the core code is posted here, the rest of the code can refer to JavaMail (i): send Simple Mail with JavaMail

Test code:

 Public classJavamailtest { Public Static voidMain (string[] args) {
Set up message-related information mailsenderinfo mailinfo=NewMailsenderinfo (); Mailinfo.setmailserverhost ("Smtp.163.com"); Mailinfo.setmailserverport ("25"); Mailinfo.setvalidate (true); Mailinfo.setusername ("[Email protected]"); Mailinfo.setpassword (""); Your email password, if your mailbox opens the client authorization password, here is your client authorization password mailinfo.setfromaddress ("[Email protected]"); Mailinfo.settoaddress ("[Email protected]"); Mailinfo.setsubject ("This is a test e-mail"); Mailinfo.setcontent (Hello This is a test e-mail "); String[] FileName= {"Craftsman. docx"};        Mailinfo.setattachfilenames (FileName); Try {            //Email.sendtextmail (Mailinfo); //Email.sendhtmlmail (mailinfo);Email.sendcomplexmail (Mailinfo); } Catch(Exception e) {e.printstacktrace (); }    }}
