## [一、开启SMTP服务][SMTP] ##

## 二、编码 ##

1、加依赖(pom.xml)

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

2、写配置（application.properties)

##mail
    spring.mail.host=smtp.qq.com
    spring.mail.username=自己的邮箱@qq.com
    spring.mail.password= 邮箱授权码
    #spring.mail.default-encoding=UTF-8
    spring.mail.properties.mail.smtp.ssl.enable=true
    spring.mail.properties.mail.smtp.ssl.trust=smtp.qq.com
    spring.mail.properties.mail.socketFactory.class=javax.net.ssl.SSLSocketFactory
    spring.mail.properties.mail.smtp.socketFactory.port=465
    spring.mail.properties.mail.smtp.port=465
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true

## 三、发送邮件 ##

1、发送html邮件

@RestController
    public class MailController {
        @Autowired
        private JavaMailSender javaMailSender;
        @Autowired
        private MailProperties mailProperties;
        @GetMapping("/html")
        public String html() throws MessagingException {
            MimeMessage message = javaMailSender.createMimeMessage();
            MimeMessageHelper messageHelper = new MimeMessageHelper(message);
    
            messageHelper.setFrom(this.mailProperties.getUsername());
            messageHelper.setTo("@qq.com");
            messageHelper.setSubject("HTML内容邮件测试");
            // 第二个参数表示是否html，设为true
            messageHelper.setText("<h1>HTML内容..</h1>", true);
    
            this.javaMailSender.send(message);
            return "success";
        }
    }

2、发送带附件的邮件

@GetMapping("/attach")
        public String attach() throws MessagingException {
            MimeMessage message = this.javaMailSender.createMimeMessage();
            // 第二个参数表示是否开启multipart模式
            MimeMessageHelper messageHelper = new MimeMessageHelper(message, true);
    
            messageHelper.setFrom(this.mailProperties.getUsername());
            messageHelper.setTo("@qq.com");
            messageHelper.setSubject("带附件的邮件测试");
            // 第二个参数表示是否html，设为true
            messageHelper.setText("<h1>HTML内容..</h1>", true);
            messageHelper.addAttachment("2b1ae927328f17aab060e2206198b91.jpg",
                    new File("src/main/resources/2b1ae927328f17aab060e2206198b91.jpg"));
    
            this.javaMailSender.send(message);
            return "success";
        }

## 注意： ##

附件路径问题：  
1、附件放在resource目录下应src/main/resources/2b1ae927328f17aab060e2206198b91.jpg

2、附件放在其他位置  
C:\\Users\\huo\\Desktop\\一个文件夹\\大二下学期\\2b1ae927328f17aab060e2206198b91.jpg
