## 快速上手: ##

#### pom.xml ####

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

#### application.yml ####

spring: 
        mail:
            # host: smtp.exmail.qq.com #企业
            host: smtp.qq.com  # 个人
            # 端口号465或587
            port: 587
            # 你的邮箱 或者 企业邮箱
            username: you_email@qq.com
            # 这里QQ邮箱开通POP3/SMTP提供的授权码，如果邮箱服务商没有授权码，可以使用密码代替
            password: pwd_or_code
            # 下面默认就好
            protocol: smtp
            default-encoding: UTF-8

com.quaint.demo.mail.helper.MailHelper

@Component
    public class MailHelper { 
    
        /** * 注入 JavaMailSender */
        @Autowired
        private JavaMailSender mailSender;
    
        /** * 注入配置文件中的 username 用来当发送邮件的邮箱 */
        @Value("${spring.mail.username}")
        private String senderEmail;
    
    
        // ======= function test ======= 
    
        /** * 发送包含简单文本的邮件 * @param toMail 要发送的 邮箱地址 * @param title 邮件标题 * @param text 邮件内容 */
        public void sendText(String toMail,String title,String text) { 
            SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
            // 设置收件人
            simpleMailMessage.setTo(new String[] { toMail});
            //寄件人
            simpleMailMessage.setFrom(senderEmail);
            simpleMailMessage.setSubject(title);
            simpleMailMessage.setText(text);
            // 发送邮件
            mailSender.send(simpleMailMessage);
    		System.out.printf("---邮件已发送---");
        }
    
        /** * 发送包含简单html文本的邮件 * @param toMail 要发送的 邮箱地址 * @param title 邮件标题 * @param text 邮件内容 * @throws Exception ex */
        public void sendHtml(String toMail,String title,String text) throws Exception { 
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage);
            //发送到传进来的邮箱
            mimeMessageHelper.setTo(toMail);
            mimeMessageHelper.setFrom(senderEmail);
            mimeMessageHelper.setSubject(title);
            StringBuilder sb = new StringBuilder();
            sb.append("<html><head></head><body>");
            sb.append(text);
            sb.append("</body></html>");
            // 启用html
            mimeMessageHelper.setText(sb.toString(), true);
            // 发送邮件
            mailSender.send(mimeMessage);
    		System.out.printf("---邮件已发送---");
