我正在创建一个应用程序2.2.1并尝试添加电子邮件工具到它.为此我已经在我的build.sbt文件中添加了依赖项.但是获得了下面解释的异常
我的代码
String smtpHost = Play.application().configuration().getString("smtp.host");
Integer smtpPort = Play.application().configuration().getInt("smtp.port");
String smtpUser = Play.application().configuration().getString("smtp.user");
String smtpPassword = Play.application().configuration().getString("smtp.password");
Email mail = new SimpleEmail();
try {
mail.setFrom("mymail@gmail.com");
mail.setSubject("hi");
mail.setMsg("This is the message");
mail.addTo("mymail2@gmail.com");
} catch (Exception e) {
e.printStackTrace();
}
mail.setHostName(smtpHost);
if (smtpPort != null && smtpPort > 1 && smtpPort < 65536) {
mail.setSmtpPort(smtpPort);
}
if (!smtpUser.isEmpty()) {
mail.setAuthentication(smtpUser,smtpPassword);
}
try {
mail.send();
} catch (Exception e) {
e.printStackTrace();
}
application.conf中包含的代码
# Email Configuration smtp.host=smtp.gmail.com smtp.port=587 smtp.ssl=yes smtp.user="mymail@gmail.com" smtp.password="123456" smtp.auth=true smtp.STARTTLS.enable=true
但我得到一个例外

我怎么解决这个问题？
解决方法
我认为您必须在发送电子邮件之前指定您发送TLS电子邮件.
mail.setTLS(true);
我不是100％肯定,但我认为它可以解决问题.
