javamail邮件发送

Posted 2021-01-07 爱吃香蕉和菠萝

第一步：maven引入javamail相关jar包

<!-- javamail邮件发送 -->
		<dependency>
			<groupId>javax.mail</groupId>
			<artifactId>mail</artifactId>
			<version>1.4.4</version>
		</dependency>
<!-- javamail邮件发送 -->

　　　　

第二步：工具类已测试（注意：发送人邮箱要开启smtp服务，使用授权码作为密码）

public class SendMailText {

        Properties props = new Properties();
        //设置用户的认证方式

        Session session = Session.getInstance(props);
        //设置调试信息在控制台打印出来
        session.setDebug(true);
        //3、创建邮件的实例对象
        Message msg = getMimeMessage(session,title,content);
        //4、根据session对象获取邮件传输对象Transport

        //设置发件人的账户名和密码
        transport.connect(senderAccount, senderPassword);
        //发送邮件，并发送到所有收件人地址，message.getAllRecipients() 获取到的是在创建邮件对象时添加的所有收件人, 抄送人, 密送人

        //如果只想发送给指定的人，可以如下写法
        //transport.sendMessage(msg, new Address[]{new InternetAddress("[email protected]")});
         
        //5、关闭邮件连接
        transport.close();
    }
     
    /**
     * 获得创建一封邮件的实例对象

        msg.setFrom(new InternetAddress(senderAddress));
        /**

        msg.setRecipient(MimeMessage.RecipientType.TO,new InternetAddress(recipientAddress));
        //设置邮件主题
        msg.setSubject(title,"UTF-8");
