如何解决Spring Boot-从应用程序发送电子邮件显示禁止错误
我想在我的Spring Boot应用程序中实现一个简单的反馈服务。用户必须提供三种不同类型的数据：发件人电子邮件，主题和消息。点击发送按钮后，它将把该消息发送到我们提到的电子邮件中（已发送到 application.yml 文件中）。但是，当我尝试使用swagger测试它时，它显示 Forbidden 错误并返回我的控制器路径。
编辑：我在控制器的send方法中放置了一个断点，但是Intellij无法识别该断点。我不确定，在邮件配置中可能仍然存在问题。
昂扬的I / p：
{
"body": "Hello","subject": "Hii","toemail": "The GMail I mentioned in application.yml"
}
点击发送后日志没有错误：
