基于Javamail发送邮件(QQ/网易邮件服务器)

一. 使用QQ邮箱作为smtp邮件服务器发送邮件

步骤1.开启QQ邮箱的POP3/SMTP服务:

开启后会得到一个16位授权码, 作为第三方使用邮件服务器的登录凭证.
注意: 修改邮箱密码后, 授权码会失效, 需要重新获取.

步骤2: 编写配置文件applicationContext-email.xml(此处使用xml配置方式):

	
		
			
			smtp.qq.com
		

		
			
				true
				
				25000
			
		
		
		
			[email protected]
		
		
		
			qazcrslpoghcbahh
		
		
			UTF-8
		
	

	
		
		
	

步骤3: 编写测试类:

package emailtest;

import java.util.Date;

import javax.annotation.Resource;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.util.StringUtils;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext-email.xml")
public class EmailTest {

	@Resource
	private JavaMailSender javaMailSender;

	@Resource
	private SimpleMailMessage simpleMailMessage;
	
	@Test
	public void sendMail() throws MessagingException{
		sendMail("[email protected]","验证码:6666","密码找回");
	}
	
	public void sendMail(String email, String content, String subject) throws MessagingException {
		MimeMessage message = javaMailSender.createMimeMessage();
		MimeMessageHelper messageHelper;
		messageHelper = new MimeMessageHelper(message, true, "UTF-8");
		messageHelper.setFrom(StringUtils.trimAllWhitespace(simpleMailMessage.getFrom()));
		messageHelper.setTo(email);
		messageHelper.setSubject(subject);
		messageHelper.setText(content, true);
		messageHelper.setSentDate(new Date());
		// 发送邮件
		javaMailSender.send(messageHelper.getMimeMessage());
		
	}
}

二. 使用网易邮箱作为smtp邮件服务器发送邮件

1.相似的, 先打开网易邮箱的POP3/SMTP服务, 设置授权码.

2.修改上述applicationContext.xml中配置信息:

	服务器地址改为smtp.163.com
	username更改为你的网易邮箱账号
	password则是你在开启POP3/SMTP服务时设置的授权码
	from的值和username值一样.
