我试图从我的播放应用中发送电子邮件。我正在使用play-mailer plugin 我已完成所有说明，但仍无法连接到gmail
application.conf
play.mailer {
debug = true
host = smtp.gmail.com
port = 465
ssl = true
ttl = false
user = "to******f@gmail.com"
password = "T****in"
}
发送任务
public static void sendSignUpMsg(MailerClient mailerClient, String verificationLink) {
Email email = new Email()
.setSubject("Simple email")
.setFrom("t***f@gmail.com")
.addTo("d****i@gmail.com")
.setBodyText("A text message");
mailerClient.send(email);
}
所以我有异常

我在我的电脑上测试服务器，可能会导致这个问题吗？
答案 0 :(得分：0)
你可能只有一个错字。 你需要tls而不是ttl
从github页面：
play.mailer {
host (mandatory)
port (defaults to 25)
ssl (defaults to no)
tls (defaults to no)
user (optional)
password (optional)
debug (defaults to no, to take effect you also need to set the log level to "DEBUG" for the application logger)
timeout (defaults to 60s in milliseconds)
connectiontimeout (defaults to 60s in milliseconds)
mock (defaults to no, will only log all the email properties instead of sending an email)
}
