怎么使用SpringBoot发送邮件

使用Spring Boot发送邮件需要进行以下步骤：

1. 添加Spring Boot邮件依赖：在项目的pom.xml文件中添加Spring Boot的邮件依赖：

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

2. 在application.properties或application.yml文件中配置邮件服务器的相关信息，例如：

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

3. 创建一个邮件发送服务类，例如EmailService：

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.mail.MailException; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.stereotype.Service;  @Service public class EmailService {      private JavaMailSender javaMailSender;      @Autowired     public EmailService(JavaMailSender javaMailSender) {         this.javaMailSender = javaMailSender;     }      public void sendEmail(String to, String subject, String text) {         try {             SimpleMailMessage message = new SimpleMailMessage();             message.setTo(to);             message.setSubject(subject);             message.setText(text);             javaMailSender.send(message);             System.out.println("邮件发送成功！");         } catch (MailException e) {             System.out.println("邮件发送失败：" + e.getMessage());         }     } } 

4. 在需要发送邮件的地方调用EmailService的sendEmail方法发送邮件：

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController;  @RestController public class EmailController {      private EmailService emailService;      @Autowired     public EmailController(EmailService emailService) {         this.emailService = emailService;     }      @GetMapping("/send-email")     public String sendEmail() {         emailService.sendEmail("recipient@example.com", "测试邮件", "这是一封测试邮件。");         return "邮件发送成功！";     } } 

以上是使用Spring Boot发送邮件的基本步骤。可以根据实际需求进行更多的配置和定制。
