Org.springframework.boot spring-boot-starter-mail

two。 Configure the mail property in application.properties

# static resource mapping, localhost:8080/ = / resourcesspring.resources.static-locations=classpath:META-INF/resources/,classpath:static/,classpath:templates/# https://blog.csdn.net/jawhiow/article/details/82625842# if the address that previously visited the home page is: http://localhost:8888/index.html, then after you configure this configuration Http://localhost:8888/default/index.htmlspring.mvc.static-path-pattern=/*# sets mailbox host spring.mail.host=smtp.qq.com# sets username spring.mail.username=xxxxxx@qq.com# sets password, the password here is the authorization code of QQ Mail to open SMTP instead of QQ password, whether authentication is required for spring.mail.password=xxxxxx# setting, if true, then username and password are required, # if false is set You don't have to set a user name and password, and of course it depends on whether your docking platform supports access without a password.
