使用java email 进行邮箱验证

第一步，先写emailUntils类

package com.yinhe.utils;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

public class MailUtils {

public static void sendMail(String email, String emailMsg)
throws AddressException, MessagingException {
// 1.创建一个程序与邮件服务器会话对象 Session

Properties props = new Properties();
props.setProperty("mail.transport.protocol", "SMTP");
props.setProperty("mail.host", "smtp.163.com");
props.setProperty("mail.smtp.auth", "true");// 指定验证为true

// 创建验证器
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("peiyifeitest222@163.com", "peiyifei888");
}
};

Session session = Session.getInstance(props, auth);

// 2.创建一个Message，它相当于是邮件内容
Message message = new MimeMessage(session);

message.setFrom(new InternetAddress("peiyifeitest222@163.com")); // 设置发送者

message.setRecipient(RecipientType.TO, new InternetAddress(email)); // 设置发送方式与接收者

message.setSubject("用户激活");
// message.setText("这是一封激活邮件，请<a href='#'>点击</a>");

message.setContent(emailMsg, "text/html;charset=utf-8");

// 3.创建 Transport用于将邮件发送

Transport.send(message);
}
}

第二步；进行激活字段更改

public int activeUser(String uid) throws SQLException{
String sql="update user set state=1 where uid=?";
QueryRunner qr=new QueryRunner(DataSourceUtils.getDataSource());
return qr.update(sql,uid);

}

第三步，在servlet中进行方法调用

String emailMsg="恭喜你注册成功，<a href='http://localhost:8081/ShopStore/UserServlet?method=activeUser&activecode="+user.getUid()+"'>请点击此处激活邮箱"
+ "如果打不开，请复制以下网址进入：<br/> http://localhost:8081/ShopStore/UserServlet?method=activeUser&activecode="+user.getUid()+"</a>"; if(result){
try {
MailUtils.sendMail(user.getEmail(), emailMsg);
response.setContentType("text/html;charset=UTF-8");
response.getWriter().println("<script> confirm('邮件发送成功'); location.href='registerSuccess.jsp';</script>");
} catch (Exception e) {
// TODO Auto-generated catch block
response.setContentType("text/html;charset=UTF-8");
response.getWriter().println("<script> confirm('邮件发送失败'); location.href='registerFail.jsp';</script>");
}
