在尝试通过gmail从java发送电子邮件时，我收到以下异常。

I am getting the following exception while trying send an email from java via gmail.

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
nested exception is:

我引用了 http://www.tutorialspoint.com/javamail_api/javamail_api_gmail_smtp_server.htm 和使用java发送电子邮件，但SSL和TLS同样会出现异常。任何解决方案？

I referred http://www.tutorialspoint.com/javamail_api/javamail_api_gmail_smtp_server.htm and Send email using java but same exception is coming both for SSL and TLS. Any fix for this?

提前感谢

推荐答案

之后您可以在GMAIL中启用SMTP访问，还需要允许您的帐户不安全的客户端（如LucasF所建议的）
尝试此配置：

After you to enable SMTP access in GMAIL, also you need to allow unsecure clients for your account ( as suggested by LucasF) Try this configuration :

host :smtp.gmail.com
port :587
username :[e-mail]
password :yourpassword
   JavaMailProperties : 
     mail.transport.protocol : smtp
     mail.smtp.auth : true
     mail.smtp.starttls.enable :true
     mail.debug :true

我使用这个配置与import org.springframework.mail.SimpleMailMessage类，它的作品。

Me I use this configuration with import org.springframework.mail.SimpleMailMessage class and it's works.
