Spring advanced-how to use Java code to implement mail sending (1), springjava
In some projects, such as the invoicing system, an alert message is issued for some inventory insufficiency, and the E-mail sending technology is required for registering users on the recruitment website to verify their email addresses. It may be easy to send emails. Open your browser, log on to your mailbox, write a letter, and send an email? So here we will talk about direct use of Java code to send emails.

Solution 1:

You can directly use SUN's JavaMail to send emails, but the code is very troublesome to write.

If you have handwritten A JavaMail email, you will be aware of the cumbersome api.

Solution 2:

Using apache Email, you can quickly send emails,

For more information, see http://commons.apache.org/email/userguide.html.

Solution 3:

Spring also provides an advanced abstraction layer for sending emails, which shields users from some details of the underlying email system and represents the client responsible for underlying resource processing.

The main package of the Spring mail abstraction layer is org. springframework. mail. It includes the main interface MailSender for sending emails, and the value object SimpleMailMessage. It encapsulates the attributes of simple emails, such as from, to, cc, subject, and text.

The package also contains a checked Exception inheritance tree rooted in MailException, which provides high-level abstraction of underlying mail system exceptions.

Ii. Spring configuration file Email-163.xml

 

Iii. Junit

 

 

Run successfully, you need to modify the user name and password configuration in the email-163.xml, as well as the content of the setForm in the test file.
