在Spring Boot中实现邮件自动推送功能，你可以使用spring-boot-starter-mail库。以下是一个简单的例子，展示了如何配置邮件服务器并发送一封简单邮件。
- 添加依赖到你的
pom.xml：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>- 在
application.properties或application.yml中配置你的邮件服务器：
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- 创建一个MailService来发送邮件：
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.SimpleMailMessage;
@Service
public class MailService {
private final JavaMailSender mailSender;
@Autowired
public MailService(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
public void sendSimpleMail(String to, String subject, String text) {
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(to);
message.setSubject(subject);
message.setText(text);
mailSender.send(message);
}
}- 在你的应用中使用MailService来发送邮件：
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MailController {
private final MailService mailService;
@Autowired
public MailController(MailService mailService) {
this.mailService = mailService;
}
@GetMapping("/sendMail")
public String sendMail() {
mailService.sendSimpleMail("recipient@example.com", "Test Subject", "This is the email content");
return "Mail sent!";
}
}确保你的应用配置了正确的邮件服务器信息，并且sendMail端点可以被调用来发送邮件。这个例子展示了如何发送文本邮件，如果你需要发送HTML邮件或者附件，你可以使用MimeMessageHelper来扩展SimpleMailMessage。
