出现错误
EmailUtility
类。sendEmail()
–它以SMTP服务器设置和邮件详细信息为参数。 我的EmailUtility
班
public class EmailUtility {
public static void sendEmail(String host, String port, final String userName, final String password,
String toAddress, String subject, String message) throws AddressException, MessagingException {
// setting SMTP server properties
Properties properties = new Properties();
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
Session session = Session.getInstance(properties, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
});
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(message);
// sending the e-mail
Transport.send(msg);
}
}
这是我的web.xml文件
<context-param>
<param-name>host</param-name>
<param-value>smtp.gmail.com</param-value>
</context-param>
<context-param>
<param-name>port</param-name>
<param-value>587</param-value>
</context-param>
<context-param>
<param-name>user</param-name>
<param-value>test.123@gmail.com</param-value>
</context-param>
<context-param>
<param-name>pass</param-name>
<param-value>12345698</param-value>
</context-param>
这是我的servlet类
public void init() {
// reading SMTP server setting from web.xml file
ServletContext context = getServletContext();
host = context.getInitParameter("host");
port = context.getInitParameter("port");
user = context.getInitParameter("user");
pass = context.getInitParameter("pass");
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// reading form fields
String recipient = request.getParameter("recipient");
String subject = request.getParameter("subject");
String content = request.getParameter("content");
System.out.println(recipient+" sub "+subject+" content "+content);
String resultMessage = "";
try {
EmailUtility.sendEmail(host, port, user, pass, recipient, subject,
content);
resultMessage = "The e-mail was sent successfully";
} catch (Exception ex) {
ex.printStackTrace();
resultMessage = "There were an error: " + ex.getMessage();
}
我在做正确的事,但不知道出什么问题
如果我在gmail中启用了不太安全的应用程序设置,那么它可以正常工作,我认为这不是解决此问题的正确方法,因为并非每个用户都愿意这样做
所以伙计们帮帮我,我不知道我在做什么怪诞,谢谢
编辑是否有其他资源可以用来在类似gmail到yahoo这样的跨平台上发送邮件,我愿意使用任何其他资源来完成我要尝试的任务
