版权

一、QQ开启SMTP

打开QQ邮箱，点击设置，进入账号，往下滑后，看见服务状态后，点击管理服务

进入管理服务后，打开服务，然后获取授权码

二、导入依赖

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

三、 yaml配置

  
spring:
  mail:
  host: smtp.qq.com
  username: "邮箱号" #可以改成你的邮箱号，需要开启smtp
  password: "授权码"
  default-encoding: UTF-8
  protocol: smtp
  port: 465
  properties:
    mail:
      smtp:
        auth: true
        socketFactory:
          class: javax.net.ssl.SSLSocketFactory
          port: 465
        ssl:
          enable: true
        starttls:
          enable: true
          required: true

四、Email工具类和EmailDTO 类

1.Email工具类

@Slf4j
@Component
public class EmailUtil{

    @Value("${spring.mail.username}")
    private String email;

    @Resource
    private JavaMailSender javaMailSender;

    @Resource
    private JavaMailSenderImpl mailSender;

    @Resource
    private TemplateEngine templateEngine;

    public void sendHtmlMail(EmailDTO emailDTO) {
        try {
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage);
            Context context = new Context();
            context.setVariables(emailDTO.getCommentMap());
            String process = templateEngine.process(emailDTO.getTemplate(), context);
            mimeMessageHelper.setFrom(email);
            mimeMessageHelper.setTo(emailDTO.getEmail());
            mimeMessageHelper.setSubject(emailDTO.getSubject());
            mimeMessageHelper.setText(process, true);
            javaMailSender.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

2. EmailDTO 类

用于封装发送所需要的信息，包括对方邮箱号，验证码、主题、内容、引用模板

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class EmailDTO implements Serializable {

    private String email;

    private String code;

    private String subject;

    private Map<String, Object> commentMap;

    private String template;

}

五、使用短信邮件发送示例

通过什么Map将所需要发送的内容进行封装，email为对方的邮箱号，subject为本次邮件的主题，最后通过EmailUtil 的sendHtmlMail（）方法进行发送即可。

	@Autowired
	private EmailUtil emailUtil;

	@Test
	public void sendMessage(){
		Map<String, Object> map = new HashMap<>();
		map.put("content", "-------发送的内容---------");
		EmailDTO emailDTO = EmailDTO.builder()
				.template("common.html")
				.email("需要发送的邮箱")
				.subject("主题")
				.commentMap(map).build();
		CompletableFuture.runAsync(()-> emailUtil.sendHtmlMail(emailDTO));
	}

common.html模板（放在项目src/main/resources/templates/common.html路径下）
