Servlet如何发送电子邮件呢？
下文讲述Servlet发送电子邮件的方法分享，如下所示:
实现思路:
Java发送邮件，通常笔者建议使用
JavaMail mail.jar 1.4.5
JAF(版本1.1.1)activation.jar
然后借助相应的API,进行电子邮件发送
例:
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
@Servlet("/sendMail")
public class SendEmail extends HttpServlet{
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
//收件人电子邮件ID
String to = "admin@java265.com";
//发件人电子邮件ID
String from = "admin@java265.com";
//假设您是从本地主机发送电子邮件
String host = "localhost";
//获取系统属性
Properties properties = System.getProperties();
//设置邮件服务器
properties.setProperty("mail.smtp.host", host);
//获取默认Session对象
Session session = Session.getDefaultInstance(properties);
//设置响应内容类型
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try{
// 创建一个默认的 MimeMessage 对象
MimeMessage message = new MimeMessage(session);
// 设置 From: header field of the header.
message.setFrom(new InternetAddress(from));
// 设置 To: header field of the header.
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
// 设置 Subject: header field
message.setSubject("This is the Subject Line!");
// 现在设置实际消息
message.setText("This is actual message");
// 发送消息
Transport.send(message);
String title = "发送电子邮件";
String res = "成功发送消息...";
String docType = "<!DOCTYPE html> \n";
out.println(docType +
"<html>\n" +
"<head><title>" + title + "</title></head>\n" +
"<body bgcolor=\"#f0f0f0\">\n" +
"<h1 align=\"center\">" + title + "</h1>\n" +
"<p align=\"center\">" + res + "</p>\n" +
"</body></html>");
}catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
