二、在web中实现邮件的发送
编写邮件发送功能
发送邮件是一件非常耗时的事情，因此这里设计一个线程类来发送邮件
package me.gacl.web.controller;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import me.gacl.domain.User;
/**
* @ClassName: Sendmail
* @Description: Sendmail类继承Thread，因此Sendmail就是一个线程类，这个线程类用于给指定的用户发送Email
* @author: 孤傲苍狼
* @date: 2015-1-12 下午10:43:48
*
*/
public class Sendmail extends Thread {
//用于给用户发送邮件的邮箱
private String from = "gacl@sohu.com";
//邮箱的用户名
private String username = "gacl";
//邮箱的密码
private String password = "邮箱密码";
//发送邮件的服务器地址
private String host = "smtp.sohu.com";
private User user;
public Sendmail(User user){
this.user = user;
}
/* 重写run方法的实现，在run方法中发送邮件给指定的用户
* @see java.lang.Thread#run()
*/
@Override
public void run() {
try{
Properties prop = new Properties();
prop.setProperty("mail.host", host);
prop.setProperty("mail.transport.protocol", "smtp");
prop.setProperty("mail.smtp.auth", "true");
Session session = Session.getInstance(prop);
session.setDebug(true);
Transport ts = session.getTransport();
ts.connect(host, username, password);
Message message = createEmail(session,user);
ts.sendMessage(message, message.getAllRecipients());
ts.close();
}catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @Method: createEmail
* @Description: 创建要发送的邮件
* @Anthor:孤傲苍狼
*
* @param session
* @param user
* @return
* @throws Exception
*/
public Message createEmail(Session session,User user) throws Exception{
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(user.getEmail()));
message.setSubject("用户注册邮件");
String info = "恭喜您注册成功，您的用户名：" + user.getUsername() + ",您的密码：" + user.getPassword() + "，请妥善保管，如有问题请联系网站客服!!";
message.setContent(info, "text/html;charset=UTF-8");
message.saveChanges();
return message;
}
}
2.2编写处理用户注册的Servlet
package me.gacl.web.controller;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import me.gacl.domain.User;
import me.gacl.service.UserService;
public class RegisterServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try{
String username = request.getParameter("username");
String password = request.getParameter("password");
String email = request.getParameter("email");
User user = new User();
user.setEmail(email);
user.setPassword(password);
user.setUsername(username);
System.out.println("把用户信息注册到数据库中");
//用户注册成功之后就使用用户注册时的邮箱给用户发送一封Email
//发送邮件是一件非常耗时的事情，因此这里开辟了另一个线程来专门发送邮件
Sendmail send = new Sendmail(user);
//启动线程，线程启动之后就会执行run方法来发送邮件
send.start();
//注册用户
//new UserService().registerUser(user);
request.setAttribute("message", "恭喜您，注册成功，我们已经发了一封带了注册信息的电子邮件，请查收，如果没有收到，可能是网络原因，过一会儿就收到了！！");
request.getRequestDispatcher("/message.jsp").forward(request, response);
}catch (Exception e) {
e.printStackTrace();
request.setAttribute("message", "注册失败！！");
request.getRequestDispatcher("/message.jsp").forward(request, response);
}
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
