springboot对JMS提供了很好的支持，对其做了起步依赖。

构架工程

创建一个springboot工程，在其pom文件加入：

        
     
      org.springframework.boot
         
     
      spring-boot-starter-mail
     
    

添加配置

spring.mail.host=smtp.163.comspring.mail.username=miles02@163.comspring.mail.password=spring.mail.port=25spring.mail.protocol=smtpspring.mail.default-encoding=UTF-8

在password 中填写自己的邮箱密码。

测试发邮件

测试代码清单如下：

spring 邮件测试
hello!this is spring mail test。
");        // cid为固定写法，imageId指定一个标识        sb.append("");        sb.append("");        // 启用html        mimeMessageHelper.setText(sb.toString(), true);        // 设置imageId        FileSystemResource img = new FileSystemResource(new File("E:/1.jpg"));        mimeMessageHelper.addInline("imageId", img);        // 发送邮件        mailSender.send(mimeMessage);        System.out.println("邮件已发送");    }    /**     * 发送包含附件的邮件     * @throws Exception     */    @Test    public void sendAttendedFileMail() throws Exception {        MimeMessage mimeMessage = mailSender.createMimeMessage();        // multipart模式        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true, "utf-8");        mimeMessageHelper.setTo("miles02@163.com");        mimeMessageHelper.setFrom("miles02@163.com");        mimeMessageHelper.setSubject("Spring Boot Mail 邮件测试【附件】");        StringBuilder sb = new StringBuilder();        sb.append("");        sb.append("
spring 邮件测试
hello!this is spring mail test。
");        sb.append("");        // 启用html        mimeMessageHelper.setText(sb.toString(), true);        // 设置附件        FileSystemResource img = new FileSystemResource(new File("E:/1.jpg"));        mimeMessageHelper.addAttachment("image.jpg", img);        // 发送邮件        mailSender.send(mimeMessage);        System.out.println("邮件已发送");    }}

测试已全部通过，没有坑。
