Question

我需要在我的数据库中发送邮件到电子邮件ID，所以有一些代码，但它在发送邮件时显示错误信息。我有一些临时代码来发送邮件，但它有错误。所以请有人帮我修复我的错误。

 <%@page contentType="text/html" pageEncoding="UTF-8"%>
 <!DOCTYPE html>
 <%@ page import="java.io.*,java.util.*,javax.mail.*"%>
  <%@ page import="javax.mail.internet.*,javax.activation.*"%>
  <%@ page import="javax.servlet.http.*,javax.servlet.*" %>
   <%
   String result;
   // Recipient's email ID needs to be mentioned.
   String to = "shanimanu@gmail.com";

   // Sender's email ID needs to be mentioned
    String from = "ashkkumar1246@gmail.com";

    // Assuming you are sending email from localhost
   String host = "localhost";

   // Get system properties object
    Properties properties = System.getProperties();

   // Setup mail server
   properties.setProperty("mail.smtp.host", host);

   // Get the default Session object.
   Session mailSession = Session.getDefaultInstance(properties);

    try{
  // Create a default MimeMessage object.
  MimeMessage message = new MimeMessage(mailSession);
  // Set From: header field of the header.
  message.setFrom(new InternetAddress(from));
  // Set To: header field of the header.
  message.addRecipient(Message.RecipientType.TO,
                           new InternetAddress(to));
  // Set Subject: header field
  message.setSubject("This is the Subject Line!");

  // Send the actual HTML message, as big as you like
  message.setContent("<h1>This is actual message</h1>",
                        "text/html" );
    // Send message
    Transport.send(message);
    result = "Sent message successfully....";
   }catch (MessagingException mex) {
    mex.printStackTrace();
    result = "Error: unable to send message....";
    }
    %>
