Springboot 配置QQ企业邮箱在阿里云服务器的坑

为了防止垃圾邮件泛滥，阿里云ECS 基于安全考虑，目前已禁用 25 端口，不再开放smtp邮件的25端口，现在需要使用465/587端口进行smtp邮件发送。具体操作步骤如下：

1、QQ企业邮箱开启开启IMAP/SMTP服务

2、springboot引入mail包

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

3、application配置

spring:
  mail:
    default-encoding: UTF-8
    host: smtp.exmail.qq.com
    port: 587
    username: ***@qq.com
    password: ********
    properties:
            mail:
                smtp:
                    auth: true
                    timeout: 25000

4、代码示例

1. @RunWith(SpringJUnit4ClassRunner.class)
2. @SpringApplicationConfiguration(classes = Application.class)
3. public class ApplicationTests {
5. @Autowired
6. private JavaMailSender mailSender;
8. @Test
9. public void sendSimpleMail() throws Exception {
10. SimpleMailMessage message = new SimpleMailMessage();
11. message.setFrom("dyc87112@qq.com");
12. message.setTo("dyc87112@qq.com");
13. message.setSubject("主题：简单邮件");
14. message.setText("测试邮件内容");
16. mailSender.send(message);
17. }
19. }

5、保证阿里云服务器的端口开放
