异常如下：
Exception in thread "main" javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
nested exception is:
java.io.IOException: Couldn't connect using "javax.net.ssl.SSLSocketFactory" socket factory to host, port: smtp.gmail.com, 465; Exception: java.lang.reflect.InvocationTargetException

at javax.mail.Transport.send(Transport.java:81)
at smack.JavaMailTest.main(JavaMailTest.java:46)
一直是这个异常，用spring整合也是这个异常
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
nested exception is:
java.io.IOException: Couldn't connect using "javax.net.ssl.SSLSocketFactory" socket factory to host, port: smtp.gmail.com, 465; Exception: java.lang.reflect.InvocationTargetException
异常就已经说明了问题所在嘛
不能用"javax.net.ssl.SSLSocketFactory"连接smtp.gmail.com, 465

楼主。不是所有邮箱的smtp都可以连的，你在做这个整合前，先得测试一下这个smtp能不能用，有些事需要收费的，比如163的。
详细测试方法google之。
每次test程序前 先test下邮箱在OUTLOOK EXPRESS中能不能发邮件，不能的话程序就发不了邮件 貌似是这样的
