【系统学习SpringBoot】SpringBoot初遇邮件服务

本篇博客主要记录博主学习SpringBoot邮件服务，主要内容有
【如何发送简单邮件】【发送html格式邮件】【发送带附件的邮件】【发送代图片的邮件】

---

一、SpringBoot配置邮件服务

【1】添加依赖

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

【2】添加配置

spring：
    mail:
       host: smtp.exmail.qq.com//腾讯的邮箱发送地址，【网易】的““mtp.qiye.163.com”
       username: *****@zslstudy.cn//博主使用的是腾讯企业邮箱，邮箱
       password: *********//这个是授权码不是登陆密码
       default-encoding: UTF-8

---

配置就这这两步，，下面详细说一下，，这个授权码的问题


【网易邮箱】，可以通过如下图获取授权码（博主试了，居然每次都设置失败，好伤心）

---

【腾讯企业邮箱】可通过如下方式获取授权码（亲测可用，很完美）

---

【qq邮箱】和腾讯企业邮箱差得有点远，，题主测了几次都不给力
生成方式和企业的类似，，下面是官方的教程（博主测了，没卵用，有兴趣的可以自己测一下，可能是博主哪里没设置好）

二、SpringBoot发送邮件
博主为了测试方便直接卸载Controller里了如下：

---

【发送简单邮件】

    @RequestMapping("sendmail")
    public String sendMail() {
        try {
            MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
            message.setFrom("小鼠标@zslstudy.cn");
            message.setTo("********@163.com");
            message.setSubject("简单文本");
            message.setText("测试邮件内容，，<h1>简单文本</h1>");

            this.mailSender.send(mimeMessage);

        } catch (MessagingException e) {
            e.printStackTrace();
        }
        return "send success";
    }

---

【发送html格式邮件】

    @RequestMapping("sendmail_html")
    public String sendMailHtml() {
        try {
            MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
            message.setFrom("小鼠标@zslstudy.cn");
            message.setTo("********@163.com");
            message.setSubject("带Html的邮件");
            message.setText("测试邮件内容<br/><hr/><br/><h2>带html</h2>", true);

            this.mailSender.send(mimeMessage);

        } catch (MessagingException e) {
            e.printStackTrace();
        }
        return "send success";
    }

---

【发送带附件的邮件】

   @RequestMapping("sendmail_attachment")
    public String sendMailAttachment() {
        try {
            MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true);
            message.setFrom("小鼠标@zslstudy.cn");
            message.setTo("********@163.com");
            message.setSubject("带附件的邮件");
            message.setText("测试邮件内容", true);

            //添加附件
            FileSystemResource file = new FileSystemResource(new File("src/main/resources/static/测试"));
            message.addAttachment("测试", file);
            this.mailSender.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
        return "send success";
    }

---

【发送代图片的邮件】

    @RequestMapping("sendmail_img")
    public String sendMailImg() {
        try {
            MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true);
            message.setFrom("小鼠标@zslstudy.cn");
            message.setTo("********@163.com");
            message.setSubject("带图片的邮件");
            message.setText("测试带图片的邮件发送");

            FileSystemResource res = new FileSystemResource(new File("src/main/resources/static/6.jpg"));
            message.addInline("2", res);//感觉不去作用,非要使用内镶图片的话，，感觉html格式的可以实现
            this.mailSender.send(mimeMessage);

        } catch (MessagingException e) {
            e.printStackTrace();
        }
        return "send success";
    }
