Question

使用servlet发送邮件时显示错误（在eclispe中）。我在类路径中也包含mail.jar和activation.jar。

我的servlet代码看起来像

import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Controller extends HttpServlet 
{
    private static final long serialVersionUID = 1L;
    public Controller() {
        super();
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
        doProcess(request,response);
    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
        doProcess(request,response);
    }
    protected void doProcess(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {
        final String user = request.getParameter("email");
        final String pwd = request.getParameter("pwd");
        String sub = request.getParameter("subject");
        String body = request.getParameter("msg");
        String to = "shiladitya1093@gmail.com";

        //Get the session object
        Properties props = new Properties();
        props.put("mail.smtp.host","localhost");
        props.put("mail.smtp.auth","true");
        Session session = Session.getDefaultInstance(props,  
                 new javax.mail.Authenticator() {  
                  protected PasswordAuthentication getPasswordAuthentication() {  
                   return new PasswordAuthentication(user,pwd);  
                   }  
                });

        //Compose message
        try{
            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(user));
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            message.setSubject(sub);
            message.setText(body);

        //Send message
            Transport.send(message);
        }catch(MessagingException e){
            throw new RuntimeException(e);
        }

        request.setAttribute("sendMsg","Message successfully send.");
        RequestDispatcher rd = request.getRequestDispatcher("contactus.jsp");
        rd.forward(request, response);
    }
}

错误如下：

HTTP状态500 - javax.mail.AuthenticationFailedException：535未定义SMTP服务器。在您的帐户中使用真实服务器地址而不是127.0.0.1。

Answer 1

您可以查看以下内容吗？ 1）您的SMTP服务器是否在本地计算机上配置。 2）尝试使用您要发送邮件的机器的机器名称或IP地址而不是localhost。

还要提供一些有关邮件目标的详细信息（即此邮件的目的地在何处）。在此基础上你可以得到更好的回应。
