springboot发送html邮件

Spring Boot可以通过JavaMailSender发送HTML邮件。以下是发送HTML邮件的步骤：

1. 在pom.xml文件中添加以下依赖项：

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

2. 在application.properties文件中添加SMTP服务器的配置信息：

spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=your-email@gmail.com
spring.mail.password=your-email-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

3. 创建一个邮件服务类，该类使用JavaMailSender发送HTML邮件：

@Service
public class EmailService {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendHtmlEmail(String to, String subject, String htmlBody) throws MessagingException {
        MimeMessage message = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, true, "UTF-8");
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(htmlBody, true);
        javaMailSender.send(message);
    }
}

4. 在需要发送HTML邮件的地方调用邮件服务类的sendHtmlEmail方法：

@Autowired
private EmailService emailService;

public void sendEmail() throws MessagingException {
    String to = "recipient-email@example.com";
    String subject = "Test HTML Email";
    String htmlBody = "<h1>Hello World!</h1><p>This is a test HTML email.</p>";
    emailService.sendHtmlEmail(to, subject, htmlBody);
}

以上就是使用Spring Boot发送HTML邮件的步骤。
