无法在Azure项目中发送电子邮件Java

Question

我有一个问题，我进行了很多研究，花了很多时间，但无法解决。

我有一个Java Web应用程序，它在一天中的特定时间向某些用户发送警报电子邮件。 完成了本地测试，并且一切正常，但是当我将应用程序上到Azure时，它不会发送电子邮件。 我正在使用来自Gmail的电子邮件进行身份验证和发送电子邮件。

我正在使用Commons Email 1.4。

由于我启用了Gmail选项，因此无法通过设备发送低安全性。

public static String sendEmail(String to, String name, String subject, String body) {
        SimpleEmail email = new SimpleEmail();
        try {
            email.setHostName("smtp.gmail.com");
            email.setSmtpPort(465);
            email.setAuthenticator(new DefaultAuthenticator("xxxxxxxxxx@gmail.com", "xxxxxxxxxxxxxxxx"));
            email.setSSLOnConnect(true);
            email.setFrom("xxxxxxxxxxxxxxx@gmail.com");
            email.setSubject(subject);
            email.setMsg(body);
            email.addTo(to, name);
            email.send();

            return "sent";
        } catch (EmailException e) {
            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw);
            e.printStackTrace(pw);
            return sw.toString(); 
        }
    }

希望对我有帮助。 我不知道该怎么办。 谢谢！

我转载了这个问题。 这是由于Gmail安全政策所致，该政策允许安全性较低的应用。 您可以参考Google accouts帮助https://support.google.com/accounts/answer/6010255?hl=zh_CN 。

解决方案是打开不安全应用程序的访问权限，请参见下图：

点击https://www.google.com/settings/security/lesssecureapps?hl=zh-CN的 “安全应用程序少”部分，然后将其打开，请参见下文。

但是，如果要在Azure上发送电子邮件，我建议在Azure上使用SendGrid进行发送，请参阅https://azure.microsoft.com/zh-cn/documentation/articles/store-sendgrid-java-how -发送电子邮件/尝试一下。
