Java 邮件认证失败异常

Question

我在使用 JavaMail 时遇到问题

javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8  https://support.google.com/mail/?p=BadCredentials ru12-20020a17090b2bcc00b001cb6527ca39sm4977241pjb.0 - gsmtp

我在 application.properties 上的配置

spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username={my email}
spring.mail.password={my password}
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

我在 Settings account.google.com 上阅读了一些解决方案，例如“打开不太安全的应用程序”，但那是旧文章，现在 google 不再允许使用此功能。

不知道怎么解决？

不要使用 Gmail 登录密码，而是使用您的 Gmail 安全性中生成的应用密码。生成应用密码的步骤在这里。 https://www.techmazza.com/solve-java-mail-authentication-failed-exception-in-springboot/
