我有一个 Java Web 项目。我正在尝试将联系我们部分添加到我的网络项目中。 Netbeans 没有警告我任何内容，但是当我填写文本框并单击按钮时，邮件不会发送。
这是我的servlet代码：
@WebServlet(name = "MailDispatcherServlet", urlPatterns = {"/MailDispatcherServlet"})
public class MailDispatcherServlet extends HttpServlet {
@EJB
private MailSenderBean mailSender;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
String toEmail = request.getParameter("email");
String subject = request.getParameter("subject");
String message = request.getParameter("message");
String fromEmail = "[email protected]";
String usurname = "gorkemsoftware";
String password = "mypasword";
try (PrintWriter out = response.getWriter()) {
/* TODO output your page here. You may use following sample code. */
mailSender.sendEmail(fromEmail, usurname, password, toEmail, subject, message);
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>MAIL STATUS</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>MAIL STATUS !!!</h1>");
out.println("<b>MAIL SENT SUCCESSFULLY </b><br>");
out.println("Click <a href='frmMail.jsp'>here</a> to go back!!!");
out.println("</body>");
out.println("</html>");
}
}
这是我的 Bean 代码：
@Stateless
public class MailSenderBean {
public void sendEmail(String fromEmail, String username, String password,
String toEmail, String subject, String message){
try {
Properties props = System.getProperties();
props.put("mail.smtp.host", "stmp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.fallback", "false");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(true);
Message mailMessage = new MimeMessage(mailSession);
mailMessage.setFrom(new InternetAddress(fromEmail));
mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
mailMessage.setContent(message, "text/html");
mailMessage.setSubject(subject);
Transport transport = mailSession.getTransport("smtp");
transport.connect("smtp.gmail.com", username, password);
transport.sendMessage(mailMessage, mailMessage.getAllRecipients());
} catch (Exception ex) {
Logger.getLogger(MailSenderBean.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
有人可以告诉我这个项目出了什么问题吗？邮件地址和密码也正确。我更改了 Gmail 的安全设置。
这是我单击发送按钮时的输出：
邮件状态！！！
邮件发送成功
点击此处返回！！！
我认为通过 SSL（端口 465）发送邮件时我们有 pb： 我更喜欢对您的代码进行一些更改，如下所示：
public void sendEmail(String fromEmail, String username, String password,
String toEmail, String subject, String message){
try {
Properties props = System.getProperties();
props.put("mail.smtp.host", "stmp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.ssl.enable", "true"); // added
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.fallback", "false");
Authenticator auth = new SMTPAuthenticator(username, password); // changed
Session mailSession = Session.getInstance(props, auth); // changed
mailSession.setDebug(true);
Message mailMessage = new MimeMessage(mailSession);
mailMessage.setFrom(new InternetAddress(fromEmail));
mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
mailMessage.setContent(message, "text/html");
mailMessage.setSubject(subject);
InternetAddress[] smtpAddress = { new InternetAddress("stmp.gmail.com") }; // changed
Transport transport = mailSession.getTransport(smtpAddress[0]); // changed
transport.connect();// changed
transport.sendMessage(mailMessage, mailMessage.getAllRecipients());
transport.close(); // added
} catch (Exception ex) {
Logger.getLogger(MailSenderBean.class.getName()).log(Level.SEVERE, null, ex);
}
}
SMTPAuthenticator 类：
private class SMTPAuthenticator extends Authenticator {
String username = null;
String password = null;
SMTPAuthenticator(String user, String pass) {
username = user;
password = pass;
}
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
}
