用spring發送郵件時發生異常

Question

我正在嘗試用Java發送郵件，我用google搜索了它，發現了一段代碼，然后嘗試運行它，但它給了我一個例外：我正在使用Spring Hibernate Integration on Projects。在這項工作中，我有xml文件獲取包含按鈕，控制器和Java類的bean，jsp頁面。

請幫我解決問題。我嘗試了google中的很多代碼。最后遇到了同樣的異常：

如果您還有其他方法可以通過spring將消息發送到有效的mailid，請提供代碼。 謝謝

Answer 1

未經身份驗證，不能使用GMail。 您需要使用端口465而不是587 。

請查看http://email.about.com/od/accessinggmail/f/Gmail_SMTP_Settings.htm

用於從任何電子郵件程序通過Gmail發送郵件的Gmail SMTP服務器設置為：

Gmail SMTP server address: smtp.gmail.com
Gmail SMTP user name: Your full Gmail address (e.g. example@gmail.com)
Gmail SMTP password: Your Gmail password
    With Gmail 2-step authentication enabled, use an application-specific Gmail password.
Gmail SMTP port (TLS): 587
    Gmail SMTP port (SSL): 465 
Gmail SMTP TLS/SSL required: yes

        transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
        transport.close();

    }

Answer 2

非常感謝您的深思熟慮的禮物。我成功收到了郵件...我的網絡中存在端口號465的連接問題。今天已解決。

我只是嘗試使用javamail-1.4.5.jar的Java應用程序

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

 final String senderEmailID = "typesendermailid@gmail.com";

 final String emailServerPort = "465";
 String receiverEmailID = null;
 static String emailSubject = "Test Mail";
 static String emailBody = ":)";
 public MailSender(String receiverEmailID, String emailSubject, String emailBody)
 {
this.receiverEmailID=receiverEmailID;
this.emailSubject=emailSubject;
 this.emailBody=emailBody;
 Properties props = new Properties();
 props.put("mail.smtp.user",senderEmailID);
 props.put("mail.smtp.host", emailSMTPserver);
 props.put("mail.smtp.port", emailServerPort);

 SecurityManager security = System.getSecurityManager();
 try

 MimeMessage msg = new MimeMessage(session);
 msg.setText(emailBody);
 msg.setSubject(emailSubject);

 msg.addRecipient(Message.RecipientType.TO,

 }
