springboot实现邮件任务

导入关键jar包：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
    <version>2.2.6.RELEASE</version>
</dependency>

在application.properties中添加邮件配置：

#发送者的邮箱
spring.mail.username=[e-mail]
#邮箱秘钥
spring.mail.password=nxnoashhoanvdfaf
#邮箱主机
spring.mail.host=smtp.qq.com
#开启qq邮箱的安全认证
spring.mail.properties.mail.smtp.ssl.enable=true

在测试类中测试简单邮件任务

@SpringBootTest
class SpringbootShrioApplicationTests {
   
    //引入邮件实现类
    @Autowired
    JavaMailSenderImpl mailSender;
    @Test
    void contextLoads() {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setSubject("第一个邮件test");
        mailMessage.setText("你好");
        mailMessage.setTo("[e-mail]");
        mailMessage.setFrom("[e-mail]");

        mailSender.send(mailMessage );

    }

会在QQ邮箱中收到相应的信息

在测试类中测试复杂邮件任务，比如可以支持附件的传输

@Test
    void contextLoads2() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setSubject("复杂邮件");
        helper.setText("<p style='color:red'>复杂邮件测试内容</p>",true);
        helper.addAttachment("奥特.png",new File("E:\\桌面\\奥特.png"));
        helper.setTo("[e-mail]");
        helper.setFrom("[e-mail]");


        mailSender.send(mimeMessage);

    }

至此，springboot就简单的使用的邮件功能
