springboot与任务（邮件任务）

• 邮件发送需要引入spring-boot-starter-mail
• Spring Boot 自动配置MailSenderAutoConfiguration
• 定义MailProperties内容，配置在application.yml中
• 自动装配JavaMailSender

• 测试邮件发送

1. pom文件配置：

       <!--邮件发送-->
           <dependency>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-mail</artifactId>
           </dependency>

2. applicationproperties配置：

   spring.mail.username=442624769@qq.com
   #自己邮箱的授权码
   spring.mail.password=lufufllqrylobijg
   spring.mail.host=smtp.qq.com
   
   #开启安全（有时需要）
   spring.mail.properties.mail.smtp.ssl.enable=true

3. 测试类：

   @RunWith(SpringRunner.class)
   @SpringBootTest
   public class Springboot04TaskApplicationTests {
   
       @Autowired
       JavaMailSenderImpl mailSender;
   
       @Test
       public void contextLoads() {
           //创建一个简单的消息邮件
           SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
           simpleMailMessage.setSubject("通知-今晚开会");
           simpleMailMessage.setText("今晚7点30开会");
   
           simpleMailMessage.setTo("2163370170@qq.com");
           simpleMailMessage.setFrom("442624769@qq.com");
           mailSender.send(simpleMailMessage);
       }
   
       @Test
       public void test02() throws MessagingException {
           //创建一个复杂的消息邮件
   
           MimeMessage mimeMessage = mailSender.createMimeMessage();
           //准备上传文件
           MimeMessageHelper helper =  new MimeMessageHelper(mimeMessage,true);
           //邮件设置
           helper.setSubject("通知-今晚开会");
           //设置写的这段内容为html
           helper.setText("<b style='color:red'>今天7：30开会</b>",true);
   
           helper.setTo("2163370170@qq.com");
           helper.setFrom("442624769@qq.com");
   
           //上传文件
           helper.addAttachment("1.png",new File("C:\\Users\\44262\\Desktop\\1.png"));
   
           mailSender.send(mimeMessage);
   
       }
   }
