1 /**2 * This type of test message is sent in HTML form3 */4  Public classSinglemailsend {5     StaticApplicationContext Actx =6         NewClasspathxmlapplicationcontext ("Applicationcontext.xml");7     StaticMailSender sender = (mailsender) actx.getbean ("MailSender");8     StaticSimplemailmessage MailMessage =9(simplemailmessage) Actx.getbean ("MailMessage"));Ten      Public Static voidMain (String args[])throwsmessagingexception { OneMailmessage.setsubject ("Hello"); AMailmessage.settext ("This is a small program that sends mail through the spring framework"); -Mailmessage.setto ("****** @qq. com"); - sender.send (mailmessage); the     } -}
