邮件任务

1. 引入pom依赖

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

2. application.properties

   spring.mail.username=你的QQ邮箱
   spring.mail.password=你的QQ授权码
   spring.mail.host=smtp.qq.com
   # qq需要配置ssl
   spring.mail.properties.mail.smtp.ssl.enable=true
   

   授权码获取步骤：

   在QQ邮箱中的设置->账户->开启pop3和smtp服务

3. Spring单元测试

   @SpringBootTest
   class SwaggerDemoApplicationTests {
       @Autowired
       JavaMailSenderImpl mailSender;
   
       @Test
       void contextLoads() {
           //邮件设置1：一个简单的邮件
           SimpleMailMessage message = new SimpleMailMessage();
           message.setSubject("我是主题");
           message.setText("我是正文");
   
           message.setTo("你的邮箱@qq.com");
           message.setFrom("你的邮箱@qq.com");
           mailSender.send(message);
       }
       
        @Test
       public void contextLoads2() throws MessagingException {
           //邮件设置2：一个复杂的邮件
           MimeMessage mimeMessage = mailSender.createMimeMessage();
           MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
   
           helper.setSubject("我是主题");
           helper.setText("我是正文");
   
           //发送附件
           helper.addAttachment("1.jpg",new File("D:\\dell\\下载\\a.png"));
   
           helper.setTo("你的邮箱@qq.com");
           helper.setFrom("你的邮箱@qq.com");
           mailSender.send(mimeMessage);
       }
   
   }
   

然后你的邮箱就会收到邮件啦！
