# 使用Spring-Boot的Mail来发送邮件，只需要导入依赖，配置参数，即可开始使用 #

*  **1.导入spring-boot-starter-mail依赖**

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

*  **2.配置邮件参数，示例QQ邮箱**  
    邮箱授权码获取方法：[QQ邮箱获取授权码][QQ]

spring.mail.host=smtp.qq.com
    spring.mail.port=587
    #发送人的邮箱
    spring.mail.username=xxx@163.com
    #授权码
    spring.mail.password=xxxxxxxxxxxxxxxx
    spring.mail.default-encoding=UTF-8
    spring.mail.properties.mail.smtp.socketFactory=javax.net.ssl.SSLSocketFactory
    spring.mail.properties.mail.debug=true

*  **3.测试发送简单邮件**

@Autowired
        JavaMailSender javaMailSender;
    
        @Test
        public void testSendMail() throws Exception { 
            MimeMessage msg = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(msg, true);
            helper.setSubject("这是一个测试邮件主题");
            helper.setText("测试邮件的内容");
            //发送人邮箱，与配置文件中保持一致
            helper.setFrom("xxx@163.com");
            //接收人邮箱
            helper.setTo("xxx@qq.com");
            helper.setSentDate(new Date());
            javaMailSender.send(msg);
        }

*  **4.测试发送携带附件的邮件**

@Autowired
        JavaMailSender javaMailSender;
    	
    	@Test
        public void testSendMailAndAccessory() throws MessagingException { 
            MimeMessage msg = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(msg, true);
            helper.setSubject("这是一个测试邮件主题(含附件)");
            helper.setText("测试邮件的内容(含附件)");
            //发送人邮箱，与配置文件中保持一致
            helper.setFrom("xxx@163.com");
            //接收人邮箱
            helper.setTo("xxx@qq.com");
            helper.setSentDate(new Date());
            helper.addAttachment("course.jpg", new File("E:\\course.jpg"));
            javaMailSender.send(msg);
        }

*  **5.测试发送携带图片的邮件**

@Autowired
        JavaMailSender javaMailSender;
    	
    	@Test
        public void testSendMailAndImg() throws Exception { 
            MimeMessage msg = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(msg, true);
            helper.setSubject("这是一个测试邮件主题(含图片)");
            helper.setText("测试邮件的内容<br/>第一张图：<img src='cid:p01'/><br/>第二张图：<img src='cid:p02'/>", true);
            //发送人邮箱，与配置文件中保持一致
            helper.setFrom("xxx@163.com");
            //接收人邮箱
            helper.setTo("xxx@qq.com");
            helper.setSentDate(new Date());
            helper.addInline("p01", new File("E:\\1.jpg"));
            helper.addInline("p02", new File("E:\\2.png"));
            javaMailSender.send(msg);
        }

*  **6.使用thymeleaf模板发送邮件**

***额外依赖：***

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

***html模板 mail.html：***

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        <div>
            <h1>Hello 欢迎 <span style="color: red" th:text="${username}"></span> 使用该邮件！</h1>
        </div>
    </body>
    </html>

@Autowired
        JavaMailSender javaMailSender;
    	
    	@Autowired
        TemplateEngine templateEngine;
    
        @Test
        public void testByThymeleafSendMail() throws Exception { 
            MimeMessage msg = javaMailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(msg, true);
    
            helper.setSubject("这是一个测试邮件主题(thymeleaf)");
            
            //进行模板渲染
            Context context = new Context();
            context.setVariable("username", "小王");
            String process = templateEngine.process("mail.html", context);
            
            helper.setText(process, true);
    		//发送人邮箱，与配置文件中保持一致
            helper.setFrom("xxx@qq.com");
            //接收人邮箱
            helper.setTo("xxx@qq.com");
            helper.setSentDate(new Date());
            javaMailSender.send(msg);
        }
