springboot整合Mail

一、开启POP3/SMTP服务

 

 二、配置pom.xml

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

三、配置application.yml

# JavaMailSender 邮件发送的配置
spring:
  mail:
    host: smtp.qq.com
    username: 12345678@qq.com
    # 授权码
    password: aaaaaaaaaaaaaaaa
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true

四、编写工具类

@Component
public class MyEmailUtil {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendEmail(String sendTo, String title, String content, File file) {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();

        try {
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
            mimeMessageHelper.setFrom("12345678@qq.com");
            mimeMessageHelper.setTo(sendTo);
            mimeMessageHelper.setSubject(title);
            mimeMessageHelper.setText(content);
            if (file.exists()) {
                FileSystemResource fileSystemResource = new FileSystemResource(file);
                mimeMessageHelper.addAttachment(file.getName(), fileSystemResource);
            }
        } catch (MessagingException e) {
            e.printStackTrace();
        }

        javaMailSender.send(mimeMessage);
    }
}
