我认为如果在Servlet中这样做会更好。
看看这里,我将给出一个基本示例,它将从html表单中获取参数,并在servlet中进行操作,如:
`@WebServlet("/Servlet")
public class Servlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public Servlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
response.setContentType("text/html");
RequestDispatcher requestDispatcher;
String from = request.getParameter("sender");
String password = request.getParameter("pass");
String to = request.getParameter("receiver");
String subject = request.getParameter("subject");
String message = request.getParameter("message");
Properties properties = System.getProperties();
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.port", "587");
if (from.contains("hotmail")) {
properties.put("mail.smtp.host", "smtp.live.com");
} else if (from.contains("gmail")) {
properties.put("mail.smtp.host", "smtp.gmail.com");
} else if (from.contains("yahoo")) {
properties.put("mail.smtp.host", "smtp.mail.yahoo.com");
} else {
out.println("<h2 style='color:red;'>Unknown domain name!!</h2><br>"
+ "<p>Please use 'Yahoo or Gmail or Hotmail'</p>");
}
Session messageSession = Session.getDefaultInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(from, password);
}
});
try {
MimeMessage mimeMessage = new MimeMessage(messageSession);
mimeMessage.setFrom(new InternetAddress(from));
mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
mimeMessage.setSubject(subject);
mimeMessage.setText(message);
Transport.send(mimeMessage);
requestDispatcher = request.getRequestDispatcher("index.html");
requestDispatcher.forward(request, response);
out.println("<h2 style='color:green;'>Message sended successfully.</h2><br>" + "<p>Welldone.</p>");
} catch (MessagingException e) {
requestDispatcher = request.getRequestDispatcher("index.html");
out.println("<h2 style='color:red;'>Fatal Error!!</h2><br>" + "<p>" + e.getMessage() + "</p>");
}
}
}
`
和基本HTML表单:
<body>
<h1 align="center">Send Email Form</h1>
<form class="cf" action="Servlet" method="post">
<div align="center">
<table>
<tr>
<td>From : </td><td><input type="email" name="sender" size="30px" class="input-email"
placeholder="Email address"></td>
</tr>
<tr>
<td>Password : </td><td><input type="password" name="pass" size="30px" class="input-email"
placeholder="Sender Password"></td>
</tr>
<tr>
<td>To : </td><td><input type="email" name="receiver" size="30px" class="input-email"
placeholder="Email address"></td>
</tr>
<tr>
<td>Subject : </td><td><input type="text" name="subject" size="30px" class="input-email"
placeholder="Subject"></td>
</tr>
<tr>
<td>Message : </td><td><textarea name="message" id="input-message"
class="text" placeholder="Message"></textarea></td>
</tr>
<tr>
<td><input type="submit" value="SEND" class="button">
</td>
<td><input type="reset" value="CLEAR" class="button">
</td>
</tr>
</table>
</div>
</form>
