Springboot Thymeleaf 发邮件 将html内容展示在邮件内容中

 

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

 

 

代码：

package com.example.demo.email;

public interface MailService {

    void sendSimpleMail(String to, String subject, String content);

    void sendHtmlMail(String to, String cc,String subject, String content);

    void sendAttachmentsMail(String to, String subject, String content, String filePath);

}

@Component

public class MailServiceImpl implements MailService {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private JavaMailSender javaMailSender;

    @Value("${spring.mail.username}")
    private String from;

    @Value("${spring.mail.bcc}")
    private String bcc;

    @Override

        } catch (Exception e) {
            logger.error("发送简单邮件时发生异常！", e);
        }

    }

    @Override
    public void sendHtmlMail(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

            FileSystemResource avatar = new FileSystemResource("image/Jasmine.png");
            helper.addInline("avatar",avatar);

            javaMailSender.send(message);
            logger.info("发送HTML邮件成功！");
        } catch (MessagingException e) {
            logger.error("发送HTML邮件时发生异常！", e);
        }
    }

    @Override

            String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
            helper.addAttachment(fileName, file);

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

<html><body><img src="cid:avatar"/></body></html>

    @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);
        }

    }

　　更新于20190701 读取图片，加载到邮件内容中

利用springboot-mail除了发送上面三种邮件格式

简单邮件内容

html邮件内容

带有附件的邮件内容，还可以读取pic，组装到对应的html中

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);

　　获取pic的路径，如果是在程序中执行，可以给出相对路径

如果部署到服务上去，我给出server的详细路径也可

html中获取用格式：

<html><body><img src="cid:avatar"/></body></html>
