Question

我设计了一个联系表格，我需要收到来自＆＃34;联系我们的邮件。页面，关于特定的电子邮件ID。

这是我的表格：

contact.html

<form action="contactservlet" method="post">
    <h4>Get in  <i>Touch</i></h4>   
    <input type="text" id="name" name="name" placeholder="NAME" class="input-style" />
    <input type="email" id="emailid" name="emailid" placeholder="EMAIl" oninput="sendRequest('GET','Checkemailid',1)" required="required" class="input-style" />
    <input type="text" id="mobno" name="mobno" placeholder="Enter Mobile No." required="required" class="input-style"/>
    <textarea type="text" id="message" name="message" placeholder="MESSAGE" required="required" class="input-style"></textarea>
    <div class="contact-btn">
        <a title="" href="#"><input type="submit" id="submit" value="Submit"/></a>
    </div>
</form>

我不知道如何撰写contactservlet.java。

试试这个，

ContactUs.html

<form action="ContactServlet" method="post">
 <h4>Get in  <i>Touch</i></h4>   
 <input type="text" id="name" name="name" placeholder="Name" />
 <input type="email" id="emailId" name="emailId" placeholder="Email" />
 <input type="text" id="mobileNo" name="mobileNo" placeholder="Enter Mobile No." />
 <textarea type="text" id="message" name="message" placeholder="Message"></textarea>
 <input type="submit" id="submit" value="Submit"/>
</form>

对于发送邮件，我们使用了JavaMail API。 Download和Documentation。

ContactServlet.java -> doPost()

    //This data will be added to your Database using DAO Layer....
    String name=request.getParameter("name");
    String emailId=request.getParameter("emailId");
    Long mobno=Long.parseLong(request.getParameter("mobileNo"));
    String message= request.getParameter("message");
    //Call Some function that do database storage.....

    //Sending Mail Through Gmail SMTP
    //Separate this code at DAO/Service Layer -  -  -
    final String gmailUsername = "somethin@gmail.com";
    final String gmailPassword = "somethin@123";
    try{
    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.port", "587");

    Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(gmailUsername, gmailPassword);
                }
            });
    Message mailMessage = new MimeMessage(session);
    mailMessage.setFrom(new InternetAddress("somethin@gmail.com"));
    mailMessage.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse(emailId));
    mailMessage.setSubject("Type Subject : ");
    mailMessage.setText("Type LONGGGG Message Here......");

    Transport.send(mailMessage);
    } catch(MessagingException e){
        e.printStackTrace();
    }

我需要代码才能从“联系我们”页面发送邮件
