Spring implements the mail sending function

Foreword: in the past, we used to send mail directly with Java's built-in mail tool. Now spring has encapsulated it for us and provided a better and simpler mail sending tool javamailsender. The settings of the mail server are not mentioned here. Just go to the QQ mailbox settings directly. Here are the main steps:

Step 1: add Maven dependencies related to sending mail

Step 2: add relevant spring configuration and create a spring mail XML (if it is spring boot, please ignore), the content is as follows:

Step 3: create a specific mail sending tool class

Step 4: create a unit test and send an email

OK, all the steps here are over. Is it much simpler and more convenient than java mail? Try it yourself!

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
