我可以使用以下代码和使用 Javamail API 发送电子邮件，通过它我可以使用“FROM”作为我的“yahoo 电子邮件 ID”发送到任何电子邮件 ID。代码:

mailFORM.html

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <title>Mail form in html</title>
    </head>
    <body>
    <table border="1" width="50%"  cellpadding="0" cellspacing="0">
    <tr>
    <td width="100%">
    <form method="POST" action="mail.jsp">
    <table border="1" width="100%" cellpadding="0" cellspacing="0">
    <h1>Mail API</h1>
    <tr>
    <td width="50%"><b>To:</b></td>
    <td width="50%"><input type="text" name="to" size="30"></td>
    </tr>
    <tr>
    <td width="50%"><b>From:</b></td>
    <td width="50%"><input type="text" name="from" size="30"></td>
    </tr>
    <tr>
    <td width="50%"><b>Subject:</b></td>
    <td width="50%"><input type="text" name="subject" size="30"></td>
    </tr>
    <tr>
    <td width="50%"><b>Description:</b></td>
    <td width="50%"><textarea name="description" type="text" 
cols="40" rows="15" size=100>
    </textarea>
    </td>
    </tr>
    <tr>
    <td><p><input type="submit" value="Send Mail" name="sendMail"></td>
    </tr>
    </table>
    </p>
    </form>
    </td>
    </tr>
    </table>
    </body>
    </html>

邮件.jsp

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <%@ page language="java" import="javax.naming.*,java.io.*,javax.mail.*,
    javax.mail.internet.*,com.sun.mail.smtp.*"%>
    <html>
    <head>
    <title>sending mail using contactus form</title>
    </head>
    <body>
    <%
    try{
    Session mailSession = Session.getInstance(System.getProperties());
    Transport transport = new SMTPTransport(mailSession,new URLName("smtp.mail.yahoo.com"));
    transport = mailSession.getTransport("smtps");
    transport.connect("smtp.mail.yahoo.com",465,"myyahooid@yahoo.com","myyahoopassword");
   MimeMessage m = new MimeMessage(mailSession);
   m.setFrom(new InternetAddress(%><%request.getParameter("from")%><%));
   Address[] toAddr = new InternetAddress[] {
   new InternetAddress(%><%request.getParameter("to")%><%)
   };
   m.setRecipients(javax.mail.Message.RecipientType.TO, toAddr );
   m.setSubject(%><%request.getParameter("subject")%><%);
   m.setSentDate(new java.util.Date());
   m.setContent(%><%request.getParameter("description")%><%, "text/plain");

   transport.sendMessage(m,m.getAllRecipients());
   transport.close();
   out.println("Thanks for sending mail!"); 
   }
   catch(Exception e){
   out.println(e.getMessage());
   e.printStackTrace();
   }
   %>
   </body>

现在，我想创建一个简单的 CONTACTUS 表单，出于显而易见的原因，我将从“mailFORM.html”文件中删除“TO”字段。因为我只希望任何访问者访问我的网站并通过输入 FROM、NAME、SUBJECT 和描述向“mycompanyid@domain.com”发送电子邮件。

那么如何解决这个输入用户名和密码的问题。因为我无法创建我在此处输入密码的代码。我无法为不同的 smtp 创建单独的代码...因为 VISITIR 访问我的网站联系页面可以通过输入他/她来自任何域的电子邮件来填写表格，例如 gmail、yahoo 等。

总而言之，我只想创建这样的表单(采用任何匿名网站)，它将详细信息发送到公司的特定电子邮件 ID，如“mycompanyid@domain.com”

最佳答案

在您的 JSP 文件中硬编码您的 To email id，但最好避免在 JSP 中编写您的 Java 代码，应该只编写方法调用。

private final String TO_EMAIL = "something@domain.com";

查看我的代码，它适用于所有 SMTPS。

package com.naveed.workingfiles;

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
 import org.apache.commons.mail.MultiPartEmail;

public class Mail {
String senderID;
String senderPassword;
String hostName;
int portNumber;
String attachmentPath;
String subject;
String body;
String cc;
String bcc;


// #=============================================================================================#
public String getBcc() {
    return bcc;
}

// #=============================================================================================#
public void setBcc(String bcc) {
    this.bcc = bcc;
}

// #=============================================================================================#
public String getCc() {
    return cc;
}

// #=============================================================================================#
public void setCc(String cc) {
    this.cc = cc;
}

// #=============================================================================================#
public String getBody() {
    return body;
}

// #=============================================================================================#
public void setBody(String body) {
    this.body = body;
}

// #=============================================================================================#
public String getSubject() {
    return subject;
}

// #=============================================================================================#
public void setSubject(String subject) {
    this.subject = subject;
}

// #=============================================================================================#

public String getSenderID() {
    return senderID;
}

// #=============================================================================================#
public void setSenderID(String senderID) {
    this.senderID = senderID;
}

public String getSenderPassword() {
    return senderPassword;
}

// #=============================================================================================#
public void setSenderPassword(String senderPassword) {
    this.senderPassword = senderPassword;
}

// #=============================================================================================#
public String getHostName() {
    return hostName;
}

// #=============================================================================================#
public void setHostName(String hostName) {
    this.hostName = hostName;
}

// #=============================================================================================#
public int getPortNumber() {
    return portNumber;
}

// #=============================================================================================#
public void setPortNumber(int portNumber) {
    this.portNumber = portNumber;
}

// #=============================================================================================#
public String getAttachmentPath() {
    return attachmentPath;
}

// #=============================================================================================#
public void setAttachmentPath(String attachmentPath) {
    this.attachmentPath = attachmentPath;
}

// #=============================================================================================#
public void sendMail(String receiverId) {

    try {
        // this below commented line for the HTML body text
        // MultiPartEmail htmlEmail = new HtmlEmail();
        // OR
        // HtmlEmail email = new HtmlEmail();

        MultiPartEmail email = new MultiPartEmail();
        // setting the port number
        email.setSmtpPort(getPortNumber());
        // authenticating the user
        email.setAuthenticator(new DefaultAuthenticator(getSenderID(),
                getSenderPassword()));
        // email.setDebug(true);
        email.setSSL(true);
        // setting the host name
        email.setHostName(getHostName());
        // setting the rciever id

        email.addTo(receiverId);

        // check for user enterd cc or not
        if (getCc() != null) {
            // add the cc
            email.addCc(getCc());
        }
        // check for user enterd bcc or not
        if (getBcc() != null) {
            // add the bcc
            email.addBcc(getBcc());
        }
        // setting the sender id
        email.setFrom(getSenderID());
        // setting the subject of mail
        email.setSubject(getSubject());
        // setting message body
        email.setMsg(getBody());
        // email.setHtmlMsg("<h1>"+getBody()+"</h1>");

        // checking for attachment attachment
        if (getAttachmentPath() != null) {
            // add the attachment
            EmailAttachment attachment = new EmailAttachment();
            attachment.setPath(getAttachmentPath());
            attachment.setDisposition(EmailAttachment.ATTACHMENT);
            email.attach(attachment);
        }

        // send the email
        email.send();
        // System.out.println("Mail sent!");
    } catch (Exception e) {
        // System.out.println("Exception :: " + e);
        e.printStackTrace();

    }
}// sendmail()
}// mail

只有您需要保存所有相应的域详细信息(主机名、端口)，基于用户电子邮件设置所有 setter 。下载所有需要的库。
