Question

javax.mail.MessagingException: Exception reading response; nested exception is:
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

Answer 1

由于许多原因，可能会发生

javax.mail.MessagingException 。由于您尚未发布任何代码，因此几乎无法正确说出导致此问题的原因。

查看错误的第二部分＆＃34; PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径＆＃34;

现在我不能100％肯定地说，但最有可能这些错误与证书有关。即很可能您的Java运行时不信任证书。

通常，Java通过标准信任链机制验证证书。但是如果该链终止于Java不信任的证书，那么Java将以上述方式抱怨。

The solution if this is the case would be to 

1. Download the certificate from the remote SMTP server

2. Import the certificate into your local truststore
