spring - SpringController Servlet.init() 发送邮件时出现异常
问题描述
我正在尝试发送邮件。但它显示 HTTP 状态 500 - Servlet。servlet Spring Controller 的 init() 抛出异常。服务器遇到了一个内部错误，导致它无法完成这个请求。
我正在通过默认邮件 ID 发送邮件，但无法发送邮件。
emailform 包含收件人和主题、消息字段。在 spring-mvc.xml 中提供的默认邮件 ID。所以我们找不到错误，请检查我的代码是否有任何错误。我认为一切都是正确的。但它显示 Servlet.init() for servlet SpringController 抛出异常。
例外
