配置jboss发送电子邮件

Question

我想从 jboss 中的 servlet 发送电子邮件。我已经在 jboss mail-service.xml 文件中进行了更改。这是我的 servlet 代码。

import java.io.*;
import java.net.*;

import java.util.Properties;
import javax.mail.AuthenticationFailedException;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.servlet.*;
import javax.servlet.http.*;

public class Email extends HttpServlet {

    protected void processRequest(HttpServletRequest request, 
                                  HttpServletResponse response)
                   throws IOException, ServletException {

        final String err = "/error.jsp";
        final String succ = "/success.jsp";

        String from = "*******@gmail.com";
        String to = "*******@yahoo.in";
        String subject = "from servlet";
        String message = "HI";
        String login = "***@gmail.com";
        String password = "*******";

        try {
            Properties props = new Properties();
            props.setProperty("mail.host", "smtp.gmail.com");
            props.setProperty("mail.smtp.port", "465");
            props.setProperty("mail.smtp.auth", "true");
            props.setProperty("mail.smtp.starttls.enable", "true");

            Authenticator auth = new SMTPAuthenticator(login, password);

            Session session = Session.getInstance(props, auth);

            MimeMessage msg = new MimeMessage(session);
            msg.setText(message);
            msg.setSubject(subject);
            msg.setFrom(new InternetAddress(from));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            Transport.send(msg);

        } catch (AuthenticationFailedException ex) {
            /*request.setAttribute("ErrorMessage", "Authentication failed");

            RequestDispatcher dispatcher = request.getRequestDispatcher(err);
            dispatcher.forward(request, response);*/
            System.out.println("Authentication failed");

        } catch (AddressException ex) {
            /*request.setAttribute("ErrorMessage", "Wrong email address");

            RequestDispatcher dispatcher = request.getRequestDispatcher(err);
            dispatcher.forward(request, response);*/
            System.out.println("Wrong Email Address");

        } catch (MessagingException ex) {
            /*request.setAttribute("ErrorMessage", ex.getMessage());

            RequestDispatcher dispatcher = request.getRequestDispatcher(err);
            dispatcher.forward(request, response);*/
            System.out.println("asdsad"+ex.getMessage());
        }
            /*RequestDispatcher dispatcher = request.getRequestDispatcher(succ);
            dispatcher.forward(request, response);*/
             System.out.println("Success");
    }

    private class SMTPAuthenticator extends Authenticator {

        private PasswordAuthentication authentication;

        public SMTPAuthenticator(String login, String password) {
            authentication = new PasswordAuthentication(login, password);
        }

        protected PasswordAuthentication getPasswordAuthentication() {
            return authentication;
        }
    }

    protected void doGet(HttpServletRequest request, 
                         HttpServletResponse response)
                   throws ServletException, IOException {
        processRequest(request, response);
    }

    protected void doPost(HttpServletRequest request, 
                          HttpServletResponse response)
                   throws ServletException, IOException {
        processRequest(request, response);
    }
}

这是我的 mail-service.xml 文件。

mbean code="org.jboss.mail.MailService" name="jboss:service=Mail">

<attribute name="User">*****@gmail.com</attribute>

    <property name="mail.from" value="[email protected]" />

    <!-- Enable debugging output from the javamail classes -->
    <property name="mail.debug" value="false" />
  </configuration>
</attribute>
<depends>jboss:service=Naming</depends>

但是在运行时我收到以下异常和根本原因。

    type Exception report

我哪里出错了？

mailservice.xml 中没有任何更改。在您的 servlet 的 doPost 方法中，删除其他所有内容并粘贴此内容。我希望它对你有用。

 String host = "smtp.gmail.com";
        String from = "[email protected]";
        String pass = "*******";
        Properties props = System.getProperties();
        props.put("mail.smtp.starttls.enable", "true"); // added this line
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.user", from);
        props.put("mail.smtp.password", pass);
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.auth", "true");

        String[] to = {"[email protected]"}; // added this line

        Session session = Session.getDefaultInstance(props, null);
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));

        InternetAddress[] toAddress = new InternetAddress[to.length];

        // To get the array of addresses
        for( int i=0; i < to.length; i++ ) { // changed from a while loop
            toAddress[i] = new InternetAddress(to[i]);
        }
        System.out.println(Message.RecipientType.TO);

        for( int i=0; i < toAddress.length; i++) { // changed from a while loop
            message.addRecipient(Message.RecipientType.TO, toAddress[i]);
        }
        message.setSubject("sending in a group");
        message.setText("Welcome to JavaMail");
        Transport transport = session.getTransport("smtp");
        transport.connect(host, from, pass);
        transport.sendMessage(message, message.getAllRecipients());
        transport.close();
