1.预热阶段：以qq邮箱为例  
(1)点击设置，切换到账户界面。

(2)下拉至POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务，开启POP3/SMTP选项。(**获取授权码，保存！**)

2.发送阶段：  
(1)引入jar包依赖：

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

(2)application.yml配置邮箱信息：

spring:
      #配置邮箱基本信息
      mail:
        #配置 SMTP 服务器地址
        host: smtp.qq.com
        #SMTP 服务器的端口
        port: 587
        #配置邮箱用户名
        username: 2636677955@qq.com
        #配置密码(POP3/SMTP授权码)
        password: fhfffugewpzmeaic
        #默认的邮件编码
        default-encoding: UTF-8
        properties:
          mail:
            smtp:
              #配饰 SSL 加密工厂
              socketFactoryClass: javax.net.ssl.SSLSocketFactory
            #开启 DEBUG 模式：发送邮件时打印日志
            debug: true

(3)发送邮件：

邮件一：

@Autowired
        JavaMailSender javaMailSender;
        @Test
        public void sendSimpleMail() {
            SimpleMailMessage message = new SimpleMailMessage();
            #设置邮件主题
            message.setSubject("一封测试邮件");
            #设置邮件发送者
            message.setFrom("2636677955@qq.com");
            #设置邮件接收者(可多个)
            message.setTo("2822911343@qq.com");
            //邮件抄送人(可多个)
    //        message.setCc("13xxxxx63@qq.com");
            //邮件隐秘抄送人(可多个)
    //        message.setBcc("16xxxxx66@qq.com");
    		#设置邮件发送日期
            message.setSentDate(new Date());
            #设置邮件的正文
            message.setText("测试邮件信息");
            #发送
            javaMailSender.send(message);
        }

效果展示如下：

邮件二：带附件的邮件

@Test
        public void sendAttachFileMail() throws MessagingException {
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
            helper.setSubject("一封附件测试邮件");
            helper.setFrom("2636677955@qq.com");
            helper.setTo("2822911343@qq.com");
    //        helper.setCc("13xxxxx63@qq.com");
    //        helper.setBcc("16xxxxx66@qq.com");
            helper.setSentDate(new Date());
            helper.setText("测试邮件信息");
            #邮箱附件地址
            helper.addAttachment("javaPic.jpg",new File("C:\\Users\\Administrator\\Desktop\\任务\\1.png"));
            javaMailSender.send(mimeMessage);
        }

邮件三：Thymeleaf 作邮件模板  
Thymeleaf 的自动化配置提供了一个 TemplateEngine，通过 TemplateEngine 可以方便的将 Thymeleaf 模板渲染为 HTML。

a.引入jar包依赖：

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

b.在 resources/templates 目录下创建一个 mail.html 作为邮件发送模板：

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <p>欢迎加入 CSDN 大家庭，您的基本信息如下：</p>
    <table border="1" width="150">
        <tr>
            <td>姓名</td>
            <td th:text="${userName}"></td>
        </tr>
        <tr>
            <td>密码</td>
            <td th:text="${passWord}"></td>
        </tr>
        <tr>
            <td>rel名字</td>
            <td th:text="${realName}"></td>
        </tr>
    </table>
    <br />
    <div style="color: #FF0000">good good study、day day up</div>
    </body>
    </html>

c.邮件测试

@Autowired
        TemplateEngine templateEngine;
    
        @Test
        public void sendThymeleafMail() throws MessagingException {
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
            helper.setSubject("一封附件测试邮件");
            helper.setFrom("2636677955@qq.com");
            helper.setTo("2822911343@qq.com");
    //        helper.setCc("37xxxxx37@qq.com");
    //        helper.setBcc("14xxxxx098@qq.com");
            helper.setSentDate(new Date());
            Context context = new Context();
            context.setVariable("userName", "尤雨溪");
            context.setVariable("passWord","123456");
            context.setVariable("realName", "vue");
            String process = templateEngine.process("mail.html", context);
            helper.setText(process,true);
            javaMailSender.send(mimeMessage);
        }
