java ssl mail_使用Javamail和Greenmail进行SMTPS / SSL
我正在尝试编写一个测试,它将使用
JavaMail SMTP或SMTPS通过SSL和身份验证向我正在运行的
Greenmail服务器发送消息.
我写了一个快速的小子,它应该完全符合我的要求：
import java.util.Properties;
import javax.mail.Session;
import javax.mail.Transport;
import com.icegreen.greenmail.user.GreenMailUser;
import com.icegreen.greenmail.util.GreenMail;
public class MailTest {
public static void main(String[] args) throws Exception {
GreenMail greenmail = new GreenMail();
try {
greenmail.start();
String email = "foo@bar";
String userid = "user";
String password = "pa$$word";
GreenMailUser setUser = greenmail.setUser(email, userid, password);
setUser.create();
GreenMailUser user = greenmail.getManagers().getUserManager().getUser(userid);
System.out.println("User created:" + user.getEmail() + ":" + user.getLogin() + ":" + user.getPassword());
int portSmtps = greenmail.getSmtps().getPort();
System.out.println("Smtps started on port:" + portSmtps);
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", "localhost");
props.put("mail.smtp.socketFactory.port", portSmtps);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
Session session = Session.getInstance(props);
Transport transport = session.getTransport("smtp");
transport.connect("localhost", portSmtps, userid, password);
System.out.println("Transport is connected: " + transport.isConnected());
} finally {
greenmail.stop();
}
}
}
我的问题是我有几个例外：

我试过在这里看一些其他答案,但我一定错过了一些东西：
对不起,很长的帖子,并提前感谢任何建议.
