本文介绍如何使用JavaMail API实现简单的纯文本邮件发送过程，包括配置邮件服务器、接收用户输入、构造邮件内容并发送。

简单的纯文本邮件发送：
1.本人安装了一个CMailServer5.3来测试邮件的收发。
 2.下载接下来需要用到的的jar包，有如下几个：
 3.启动Eclipse，建立一个标准的web项目，并在web-info/lib下引入jar包。
4.编写一个邮件输入页面：
 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>JavaMail1.html</title> </head> <body> <form action="SEND1" method="post"> From:<input type="text" name="from"><br> TO:<input type="text" name="to"><br> Subject:<input type="text" name="subject"><br> Context:<textarea rows="4" cols="30" name="context"></textarea><br> <input type="submit" value="Send"> </form> </body></html>5.编写sevlet : SEND1.java
package com.servlet;import java.io.IOException;import java.io.PrintWriter;import java.util.Date;import java.util.Properties;import javax.mail.Address;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;  public class SEND1 extends HttpServlet ...{   public SEND1() ...{ super(); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException ...{ response.setContentType("text/html"); PrintWriter out = response.getWriter(); request.setCharacterEncoding("gb2312"); String from = request.getParameter("from"); String to = request.getParameter("to"); String subject = request.getParameter("subject"); String context = request.getParameter("context"); // 确定要发送的邮件服务器的地址 String mailserver = "codedestiny-pc"; try ...{ // 设置邮件的传输协议 Properties prop = System.getProperties(); prop.put("mail.smtp.host", mailserver); // 建立邮件发送的连接 Session session = Session.getDefaultInstance(prop, null); // 创建发送的信息的载体 Message msg = new MimeMessage(session); // 设置相关的邮件属性 msg.setFrom(new InternetAddress(from)); // 点到点的发送 msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); /**//* * 群发 msg.setRecipients(Message.RecipientType.TO, new InternetAddress[]{new InternetAddress(to),new InternetAddress(to)}); //借助循环的标准发送 */ msg.setSubject(subject); msg.setSentDate(new Date()); msg.setText(context); // 发送 Transport.send(msg); } catch (Exception e) ...{ e.printStackTrace(); } out.print("send ok"); out.flush(); out.close(); } }6.测试。 |
