SpringBoot 邮件任务

SpringBoot 邮件任务

今天学习了异步任务和邮件任务等等，写篇随笔记录一下邮件任务

导入依赖(也可以自己创建SpringBoot项目时勾选上启动器)

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

开启POP3/SMTP服务(这里以QQ邮箱为例)
登录QQ邮箱，在设置->帐户寻找下面的服务

​

编写配置文件(这里使用properties)

# 填写自己的邮箱 这里以QQ邮箱为例
spring.mail.username=*********@qq.com
# 这里是自己邮箱的授权码，如果是QQ邮箱，需要自己去开启服务，并且获取授权码，其它邮箱就是自己的密码
spring.mail.password=************* 
spring.mail.host=smtp.qq.com
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
# 开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

测试

	@Autowired
    JavaMailSender javaMailSender;
	@Test
    void contextLoads() {
        //发送简单邮件
        SimpleMailMessage message = new SimpleMailMessage();
        message.setSubject("激活邮件");							//设置标题
        message.setText("您好,这是一封测试邮件,无需回复");           //设置正文
        message.setTo("2933253458@qq.com");						//发给谁
        message.setFrom("2933253458@qq.com");					//谁发的
        javaMailSender.send(message);
    }

	@Autowired
	JavaMailSender javaMailSender;
	@Test
    public void test01() throws MessagingException {
        //发送复杂邮件(html+附件)
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
        mimeMessageHelper.setSubject("激活邮件");   //设置邮件主题
        mimeMessageHelper.setText("<p>您好,这是一封测试邮件！<p>",true);//开启解析html
        //发送附件
        mimeMessageHelper.addAttachment("图片.png",new File("C:\Users\gaoteng\Desktop\Typora截图\QQ截图20200613091605.png"));
        //发给谁
        mimeMessageHelper.setTo("2933253458@qq.com");
        //谁发的
        mimeMessageHelper.setFrom("2933253458@qq.com");
        javaMailSender.send(mimeMessage);
    }

抽取工具类(这是在网上找的某大佬的，后面会附上链接)

因为测试结果太多，所以我就不贴图片了.

本篇随笔参考使用spring-boot-starter-mail实现邮件发送。
特别感谢!!!
