Springboot 集成Gmail

Spring Boot可以通过配置SMTP服务器来实现与Gmail的集成。以下是集成Gmail的步骤：
1. 在`application.properties`文件中添加以下配置：

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

请将`your-email@gmail.com`和`your-password`替换为您自己的Gmail帐户的电子邮件地址和密码。

2. 在您的Spring Boot应用程序中创建一个邮件服务类，例如`EmailService`，并注入`JavaMailSender`：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

@Service
public class EmailService {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendEmail(String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        javaMailSender.send(message);
    }
}

3. 在您的应用程序中使用`EmailService`发送电子邮件：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class EmailController {

    @Autowired
    private EmailService emailService;

    @GetMapping("/send-email")
    public String sendEmail() {
        emailService.sendEmail("recipient@example.com", "Test Email", "This is a test email.");
        return "Email sent successfully.";
    }
}

以上步骤将使您的Spring Boot应用程序能够通过Gmail SMTP服务器发送电子邮件。
