当我尝试使用spring-MVC和XML配置文件通过Web应用程序发送消息时发生崩溃。
该应用程序似乎可以正常工作，但是当我按下按钮发送消息时，我遇到了以下嵌套异常：
邮件服务器连接失败；嵌套异常为javax.mail.MessagingException：无法将套接字转换为TLS；嵌套异常为：javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException ：找不到指向请求目标的有效认证路径。失败的消息：javax.mail.MessagingException：无法将套接字转换为TLS；嵌套的异常是：javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException ：找不到指向所请求目标的有效认证路径
我使用tomcat 7和Eclipse运行该项目。
我更改了configuration.file文件中的bean，并更改了Gmail安全配置，但仍然存在相同的问题。
