Springboot实现发送邮箱

作者:互联网

1.首先开启自己邮箱客户端的功能,开启之后会给你一个密码

  1. 导入pom
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>
  1. 配置文件

    spring.mail.username=你的邮箱
    spring.mail.password=第一步配置会有一段密文
    spring.mail.host=smtp.qq.com
    
    #开启加密验证
    spring.mail.properties.mail.stml.ssl.enable=true
    
    

4.测试邮箱发送,我这边把方法直接给直接提取出来了

@SpringBootTest
class SpringbootQuerzApplicationTests {


    @Autowired
    private JavaMailSenderImpl mailSender;

    @Test
    void contextLoads() {
        HashMap<String, String> map = new HashMap<>();
        map.put("1.jpg","D:\\桌面和图片\\4k壁纸\\长发少女黑色吊带裙 好看的4k动漫美女壁纸3840x2160_彼岸图网.jpg");

        map.put("2.jpg","D:\\桌面和图片\\4k壁纸\\带眼镜的女生 面部 好看的人物插画绘画4k高清动漫壁纸_彼岸图网.jpg");
        try {
            sendMail("你好1","<div style='color=red'>你好</div>",true,map,"1625397016@qq.com","1625397016@qq.com");
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }


    /**
     *
     * @param Title 邮箱的标题
     * @param text 邮箱的内容
     * @param htmlflag 是否开启邮箱内容的html格式
     * @param Attachment 附件
     * @param to 发送给谁
     * @param from 你自己配置的
     * @throws MessagingException
     */
    private void sendMail(String Title, String text, Boolean htmlflag, Map<String,String>Attachment,String to,String from) throws MessagingException {

        //邮件消息
        MimeMessage mimeMessage = mailSender.createMimeMessage();

        //组装,增加更过功能
        MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage,true);


        //正文
        //标题
        messageHelper.setSubject(Title);
        //内容
        messageHelper.setText(text,htmlflag);

        //附件
        if(!Attachment.isEmpty()){
            List<String> keylist =new ArrayList<>(Attachment.keySet());
            for (int i = 0; i < keylist.size(); i++) {
                messageHelper.addAttachment(keylist.get(i),new File(Attachment.get(keylist.get(i))));
            }

        }
        //用户
        messageHelper.setTo(to);
        //发送给谁
        messageHelper.setFrom(from);


        mailSender.send(mimeMessage);
    }
    
    
}
