基于spring boot实现邮箱发送和邮箱验证

在Spring Boot中实现邮箱发送和验证可以使用spring-boot-starter-mail库。以下是一个简单的例子：

1. 添加依赖到你的pom.xml：

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

2. 配置application.properties或application.yml文件：

spring.mail.host=smtp.example.com
spring.mail.port=587
spring.mail.username=your_username
spring.mail.password=your_password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

3. 创建邮件发送服务：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;
 
@Service
public class EmailService {
 
    @Autowired
    private JavaMailSender mailSender;
 
    public void sendEmail(String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        mailSender.send(message);
    }
}

4. 创建邮件验证服务：（这部分取决于你的验证策略，可以是发送特定的验证链接或验证码邮件等）

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service
public class EmailVerificationService {
 
    @Autowired
    private EmailService emailService;
 
    public void sendVerificationEmail(String email, String verificationToken) {
        String verificationLink = "http://www.your-app.com/verify?token=" + verificationToken;
        emailService.sendEmail(email, "Account Verification", "Please verify your account by clicking on the following link: \n" + verificationLink);
    }
}

确保你的应用程序中包含了必要的配置，并且邮件服务器设置正确，这样你就可以通过注入EmailService来发送邮件，通过注入EmailVerificationService来进行邮件验证了。
