发送电子邮件 jhipster 时无法将连接转换为 SSL

Question

我想注册后发邮件通知，我都是按照jhipster关于配置邮件的文档做的：

mail:
    host: smtp.gmail.com
    port: 587
    username: *******@gmail.com
    password: *****
    protocol: smtp
    tls: true
    properties.mail.smtp:
        auth: true
        starttls.enable: true
        ssl.trust: smtp.gmail.com

根据 stackoverflow 上的另一个问题，我允许 google 帐户连接不太安全的应用程序，但我仍然遇到以下异常：

org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Unable to convert connection to SSL (javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed
: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target). Failed messages: javax.mail.MessagingException: Unable to convert connection to SSL (javax.net.ssl.SSLHandshakeException: sun.security.validator
.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target)

我应该怎么做才能解决这个问题？

提前谢谢你。

也许您是从没有 SSL 证书的服务器发送电子邮件？
