Spring boot集成mail发送邮件

需要先添加mail依赖

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

邮件的配置

spring:
  mail:
    host: smtp.163.com
    username: xxxxxx@163.com
    password: xxxxxxxxx   # 此密码为授权码
    enable: true
    smtp:
      auth: true
    starttls:
      enable: true
      required: true

启动文件

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class EmailSpringApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmailSpringApplication.class, args);
    }
}

编写测试类

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = EmailSpringApplication.class)
public class ApplicationTests {

    @Autowired
    private JavaMailSender mailSender;

    @Test
    public void sendSimpleEmail() {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        // 从这个邮箱发送
        mailMessage.setFrom("xxxxxx@163.com");
        // 发给下面的邮箱
//        mailMessage.setTo("xxxxxx@163.com");
//        mailMessage.setTo("xxxxxx@qq.com");
        // 邮箱的主题
        mailMessage.setSubject("主题： 验证码");
        // 邮箱的内容
        mailMessage.setText("12345678");
        mailSender.send(mailMessage);
    }
}

运行测试即可发送
