需要的依赖主要如下：

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

代码如下：

主要文件有interface Mailserver 和 MailServerImpl

如何调用

Context context = new Context();
                context.setVariable("bugnum", "bugnum#"+bugNotifyBean.getId());
                context.setVariable("pro_img", "avatar");
                context.setVariable("bugdes", bugNotifyBean.getDescription());
                context.setVariable("bugstatus", bugNotifyBean.getBugStatus());
                context.setVariable("crname", bugNotifyBean.getCrname());
                context.setVariable("crnum", bugNotifyBean.getCrnum());
                context.setVariable("oname", bugNotifyBean.getOname());
                context.setVariable("pname", bugNotifyBean.getPname());
                context.setVariable("rca", bugNotifyBean.getRca());
                context.setVariable("tasknum", bugNotifyBean.getTasknum());
                context.setVariable("solution", bugNotifyBean.getSolution());
    
    
                String emailContent = templateEngine.process("emailTemplate", context);
                mailService.sendHtmlMail(developerEmail, testerEmail,"您好，有一个Bug要关注，谢谢!!", emailContent);

1. 买坑之旅

org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: IOException while sending message;  
nested exception is:  
java.io.FileNotFoundException: image\\Jasmine.png  
; message exception details (1) are:

2. html中带有图片，即

@Override
        public void sendHtmlMailwithImage(String to, String cc, String subject, String content) {
    
            MimeMessage message = javaMailSender.createMimeMessage();
            try {
                //true表示需要创建一个multipart message
                MimeMessageHelper helper = new MimeMessageHelper(message, true);
                helper.setFrom(from);
                helper.setTo(to);//邮件接收者
                helper.setCc(cc);
                helper.setSubject(subject);//邮件主题
                helper.setText(content, true);//邮件内容
    
                String imagePath="src/main/resources/proba.jpg";
                FileSystemResource fileSystemResource = new FileSystemResource(imagePath);
    
                //FileSystemResource avatar = new FileSystemResource("image/Jasmine.png");
                System.out.println(fileSystemResource);
                helper.addInline("avatar",fileSystemResource);
                javaMailSender.send(message);
                System.out.println("发送HTML邮件成功！");
            } catch (MessagingException e) {
                System.out.println("发送HTML邮件时发生异常！"+ e);
            }
    
        }
