Java实现注册邮箱激活验证 即邮件发送功能

1.引入所需jar包

<dependency>

  <groupId>javax.mail</groupId>

  <artifactId>mail</artifactId>

  <version>1.4.4</version>

</dependency>

2.工具类

package cn.tedu.rs.common.util;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class MailUtil {

public static boolean sendEmail(String fromEmail,String toEmail,String[] connent) throws MessagingException{
Properties prop=new Properties();
prop.setProperty("mail.host", "stmp.qq.com");
prop.setProperty("mail.transport.protocol", "smtp");
prop.setProperty("mail.smtp.auth", "true");
//使用javaMail发送邮件的5个步骤
//创建session
Session session=Session.getInstance(prop);
//开启session的debug模式，这样就可以查看到成语发送Email的运行状态（测试人员用）session.setDebug(true);
//2.通过session得到transport对象
Transport ts=session.getTransport();
//3.使用邮箱的用户名和密码链接上邮件服务器，发送邮件时，发送人需要提交邮箱的用户名和密码（授权码）给smtp服务器，用户名和密码都通过验证之后
//才能够正常发送邮件给收件人，QQ邮箱需要使用SSL，端口号465或587       ts.connect("smtp.qq.com",587,"QQ号","授权码");  
ts.connect("smtp.qq.com",587,connent[2],"qivdayxytalhbbgg");  
//4、创建邮件  
Message message;  
try {  
message = createSimpleMail(fromEmail,toEmail,connent,session);  
//5、发送邮件  
ts.sendMessage(message,message.getAllRecipients());  
} catch (Exception e) {  
// TODO Auto-generated catch block  
e.printStackTrace();  
}  
ts.close();  
return true;
}
/**
* 创建邮件
* @param session
* @return
* @throws MessagingException 
* @throws AddressException 
*/
public static Message createSimpleMail(String fromEmail,String toEmail,String[] connent,Session session) throws AddressException, MessagingException{
//创建邮件
MimeMessage message=new MimeMessage(session);
//指明邮件的发送人
message.setFrom(new InternetAddress(fromEmail));
//指明收件人
message.setRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
//设置邮件的标题
message.setSubject(connent[0]);
//设置邮件的内容
message.setContent(connent[1],"text/html;charset=UTF-8");
//返回创建好的邮件对象  
return message;  
}

}

3.直接调用sendEmail方法传入相应参数即可
