我正在尝试使用数据库中的 java 发送电子邮件。在我出于某种原因运行我的主要方法后，我收到了这个错误:

Exception in thread "main" javax.mail.internet.AddressException: Illegal semicolon, not in group in string ``john@gmail.com;eric@gmail.com;carrie@gmail.com;mark@gmail.com;britney@gmail.com'' at position 23
    at javax.mail.internet.InternetAddress.parse(InternetAddress.java:929)
    at javax.mail.internet.InternetAddress.parse(InternetAddress.java:638)
    at javax.mail.internet.InternetAddress.parse(InternetAddress.java:615)
    at EmailSender.sendEmail(TestSendEmails.java:120)
    at EmailSender.sendEmail(TestSendEmails.java:128)
    at Main.main(Main.java:8)

我假设我的数组列表构建错误。这是我的代码:

public class TestSendEmails {
    private String emailTo;
    private String emailSubject;
    private String emailBody;
    private String emailAttachments;

    public TestSendEmails(){

    }

    public TestSendEmails(String emailTo, String emailSubject, String emailBody, String emailAttachments){
        super();
        this.emailTo = emailTo;
        this.emailSubject = emailSubject;
        this.emailBody = emailBody;
        this.emailAttachments = emailAttachments;
    }

    public String getEmailTo(){

    }

    }

    public String getEmailSubject(){

        this.emailBody = emailBody;
    }

    public String getEmailAttachments(){

    }

    public void setEmailAttachments(String emailAttachments){

class TestSendEmailD{
    private Connection con;

    private static final String GET_EMAILS = "Select * From Emails";

    private void connect() throws InstantiationException, IllegalAccessException, ClassNotFoundException, SQLException{

        PreparedStatement ps = con.prepareStatement(GET_EMAILS);
        ResultSet rs = ps.executeQuery();
        List<TestSendEmails> result = new ArrayList<TestSendEmails>();
        while(rs.next()){
            result.add(new TestSendEmails(rs.getString("emailTo"), rs.getString("emailSubject"),rs.getString("emailBody"),rs.getString("emailAttachments")));
        }
        disconnect();
        return result;
    }

    private void disconnect() throws SQLException{
        if(con != null){
            con.close();
        }
    }
}

class EmailSender{
    private Session session;

    private void init(){
        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "100.000.000.00");
        props.put("mail.smtp.port", "123");

        session = Session.getInstance(props,
                  new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication("work@gmail.comg", "1234");
                    }
                  });
    }

    public void sendEmail(TestSendEmails s) throws MessagingException{
        init();
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("work@gmail.com"));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(s.getEmailTo()));
        message.setSubject(s.getEmailSubject());
        message.setText(s.getEmailBody());
        Transport.send(message);
    }

    public void sendEmail(List<TestSendEmails> emails) throws MessagingException{
        for(TestSendEmails TestSendEmails:emails ){
            sendEmail(TestSendEmails);
        }
    }
}

这是我的 main.java:

public class Main {
    public static void main(String[] args) throws Exception {
        TestSendEmailD dao=new TestSendEmailD();
        List<TestSendEmails> list=dao.getTestSendEmails();
        EmailSender sender=new EmailSender();
        sender.sendEmail(list);
    }
}

有人可以帮忙吗？提前致谢。

最佳答案

默认情况下，它使用逗号(,) 分隔的电子邮件地址进行解析，而不使用分号(;),

InternetAddress[] parse = InternetAddress.parse("abc@gmail.com,pqr@gmail.com");
System.out.println(parse[0].getAddress());

输出:

abc@gmail.com
