Output

Execution Flow

• ClientLogic.java is our main class, and we are calling id2 [line number 15]
• So come to spconfig.xml and check line number 23, we are calling java4s.MailLogic.java having property mail of type JavaMailSender Interface (provided by spring), so it will moves to JavaMailSenderImpl (id1, implemented class of JavaMailSender) and there we have given all the Email related credentials
• JavaMailSender contains mail() method to send a mail
• JavaMailSender‘s mail() method contains MimeMessage class object as parameter, like mail(MimeMessage Object)
• Finally we set From,To,Subject,Msg and called send() that’s it

How simple its is ? 🙂
