Question

我正在使用Java mail api发送电子邮件。当我从自己的帐户向自己发送电子邮件时，它工作正常。但是，当我尝试向其他帐户发送电子邮件时，它会给我一个身份验证例外。这是我的代码：

package nl.cofely.MailHandler;

import java.util.Date;
import java.util.Properties;
import javax.activation.CommandMap;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.activation.MailcapCommandMap;
import javax.mail.BodyPart;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class Mail extends javax.mail.Authenticator {
private String _user;
private String[] _to;
private String _from;
private String _pass;

private String _port;
private String _sport;

private String _host;

private String _subject;
private String _body;

private boolean _auth;

private boolean _debuggable;

private boolean testMessageSend;

private Multipart _multipart;
static Mail instance;

private Mail() {
    _host = "smtp.gmail.com"; // default smtp server
    _port = "465"; // default smtp port
    _sport = "465"; // default socketfactory port

    _subject = "Person in trouble   !"; // email subject
    _body = ""; // email body

    _debuggable = false; // debug mode on or off - default off
    _auth = true; // smtp authentication - default on

    _multipart = new MimeMultipart();

    // There is something wrong with MailCap, javamail can not find a
    // handler for the multipart/mixed part, so this bit needs to be added.
    MailcapCommandMap mc = (MailcapCommandMap) CommandMap
            .getDefaultCommandMap();
    mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
    mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");

    mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
    CommandMap.setDefaultCommandMap(mc);
}
public static Mail getInstance(){
    if(instance == null){
        instance = new Mail();
    }
    return instance;
}

public void addAttachment(String filename) throws Exception {
    BodyPart messageBodyPart = new MimeBodyPart();
    DataSource source = new FileDataSource(filename);
    messageBodyPart.setDataHandler(new DataHandler(source));
    messageBodyPart.setFileName(filename);

    _multipart.addBodyPart(messageBodyPart);
}

@Override
public PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication(_user, _pass);
}

private Properties _setProperties() {
    Properties props = new Properties();

    props.put("mail.smtp.host", _host);

    if (_debuggable) {
        props.put("mail.debug", "true");
    }

    return props;
}

// the getters and setters
public String getBody() {
    return _body;
}

public void setBody(String _body) {
    _body = _body + " gebruiker: " + _from;
    this._body = _body;

public boolean send() throws Exception {

    if (!_user.equals("") && !_pass.equals("") && _to.length > 0

        msg.setFrom(new InternetAddress(_from));

        InternetAddress[] addressTo = new InternetAddress[_to.length];
        for (int i = 0; i < _to.length; i++) {
            addressTo[i] = new InternetAddress(_to[i]);
        }
        msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);

        System.out.println(_multipart.getBodyPart(0));

        // Put parts in message

        // send email

        return true;
    } else {

    }
}
public boolean sendTestMail() throws Exception{

}

}
public String getUser(){
    return _user;
}

public void updateUserInfo(String[] _to, String _from, String _pass){
    this._to = _to;
    this._from = _from;
    this._pass = _pass;
    this._user = _to[0].substring(0, _to[0].lastIndexOf("@"));
}

}

有人能说出这里发生了什么吗？感谢

尝试这样的事情：

public int sendMail(String reciever_email, String subject, String body) {
    final String username = "YOUR USER EMAIL";
    final String password = "PASSWORD";
    Properties props = new Properties();
    props.put("mail.smtp.user", username);
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.port", "25");
    props.put("mail.debug", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.EnableSSL.enable", "true");
    props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.setProperty("mail.smtp.socketFactory.fallbac k", "false");
    props.setProperty("mail.smtp.port", "465");
    props.setProperty("mail.smtp.socketFactory.port", "465");
    Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    });

    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(username));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(reciever_email));
        message.setSubject(subject);
        message.setText(body);
        Multipart multipart = new MimeMultipart("related");
        BodyPart htmlPart = new MimeBodyPart();
        htmlPart.setContent("<html>HELLO</html>", "text/html");

        multipart.addBodyPart(htmlPart);
        message.setContent(multipart);
        Transport.send(message);
        return 1;
    } catch (Exception e) {
        return 0;

    }
}
