java - Play框架使用Apache Commons发送电子邮件

Question

我正在尝试创建一个页面，该页面在Play Framework上发送带有附件的电子邮件。我首先需要知道如何发送简单的电子邮件。我正在关注
Apache Commons Userguide for Email。

   Email email = new SimpleEmail();
        email.setHostName("smtp-mail.outlook.com");
        email.setSmtpPort(587);
        email.setAuthenticator(new DefaultAuthenticator("email@outlook.com", "password"));
        email.setSSLOnConnect(true);
        email.setFrom("user@outlook.com");
        email.setSubject("Subject");
        email.setMsg("This is a test mail ... :-)");
        email.addTo("add@outlook.com");
        email.send();

执行异常：[EmailException: Sending the email to the following server failed : smtp-mail.outlook.com:465]

即使将端口设置为465，我也不知道为什么说587

终端上的异常：Caused by: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp-mail.outlook.com, 465; timeout 60000;

程序将端口号接受为465的原因是什么。

使用gmail时也会发生相同的问题

在here中回答。

您必须登录Google的“ https://www.google.com/settings/security/lesssecureapps”并启用然后运行该程序。有用。

如果未启用，则会出现以下异常

org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.googlemail.com:465
