sendmailservlet.java

关于JAVA邮件开发的源代码...很有参考价值的源代码

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class SendMailServlet extends HttpServlet
{
	public void doGet(HttpServletRequest request,
		HttpServletResponse response) throws ServletException, IOException
	{
		String smtpServer = "smtp.sina.com.cn";//邮件服务器主机名
		String protocol = "smtp";//邮件传输协议
		String username = "it315_test";//登陆用户名
		String password = "123456";//登陆密码
		String from = "[e-mail] ";//发件人地址
		String to = "[e-mail] ";//收件人地址
		String subject = "authenticator demo";//邮件主题
		String body = "authenticator demo";//邮件内容
     
		//获得Session对象
		Context initCtx = new InitialContext();
		Context envCtx = (Context) initCtx.lookup("java:comp/env");
		Session session = (Session) envCtx.lookup("mail/Session");

		//创建代表邮件的MimeMessage对象
		MimeMessage msg = new MimeMessage(session);
		msg.setFrom(new InternetAddress(from)); 
		msg.setRecipients(Message.RecipientType.TO,
								InternetAddress.parse(to)); 
		msg.setSentDate(new Date());
		msg.setSubject(subject); 
		msg.setText(body);
		//保存并生成最终的邮件内容
		msg.saveChanges();

		Transport transport = session.getTransport();
		transport.connect(smtpServer,username,password);
		transport.sendMessage(msg,
        				  msg.getRecipients(Message.RecipientType.TO));
		transport.close();
		
		response.setContentType("text/html;charset=GB2312");
		PrintWriter out = response.getWriter();	
		out.println("您的邮件已经发送成出!");
	}

	public void doPost(HttpServletRequest request,
		HttpServletResponse response) throws ServletException, IOException
	{
		doGet(request,response);
	}
