Send a message with an attachment

     /** * Send mail with attachments * @param to * @param subject * @param content * @param filePath */Public V OID Sendattachmentsmail (string to, string subject, string content, String filePath) {MimeMessage message = SENDER.C        Reatemimemessage (); Try {//true represents the need to create a multipart message mimemessagehelper helper = new Mimemessagehelper (message, True            );            Helper.setfrom (from);            Helper.setto (to);            Helper.setsubject (subject);            Helper.settext (content, true);            Filesystemresource file = new Filesystemresource (new file (FilePath));            String fileName = filepath.substring (Filepath.lastindexof (file.separator));            Helper.addattachment (fileName, file);   Helper.addattachment (fileName2, file2);            Add multiple attachment sender.send (message); Logger.info ("The message with the attachment has been sent.        "); } catch (Messagingexception e) {logger.error ("an exception occurred when sending messages with attachments!        ", e); }    }

Send messages embedded in static resources

/** * Send messages embedded in static resources (typically pictures) * @param to * @param subject * @param     Content message contents, need to include the ID of a static resource, for example:  * @param rscpath Static resource path and file name * @param rscid static resource ID        */public void Sendinlineresourcemail (string to, string subject, string content, String Rscpath, String rscid) {        MimeMessage message = Sender.createmimemessage (); Try {//true represents the need to create a multipart message mimemessagehelper helper = new Mimemessagehelper (message, True            );            Helper.setfrom (from);            Helper.setto (to);            Helper.setsubject (subject);            Helper.settext (content, true);            Filesystemresource res = new Filesystemresource (new File (Rscpath));            Helper.addinline (Rscid, RES);            Sender.send (message); Logger.info ("a message embedded in a static resource has been sent.        "); } catch (Messagingexception e) {logger.error ("an exception occurred when sending messages embedded in a static resource!        ", e); }    }
