Spring Boot整合发送QQ邮箱功能

1. 创建Spring Boot项目

使用Spring Initializr（https://start.spring.io/）创建一个新的Spring Boot项目，并添加spring-boot-starter-mail依赖。

2. 添加配置

在application.properties或application.yml文件中添加QQ邮箱的SMTP配置。这里以application.yml为例：

spring:mail:host: smtp.qq.comport: 465username: [e-mail] # 你的QQ邮箱地址password: your-qq-auth-code # 你的QQ邮箱授权码properties:mail:smtp:auth: truestarttls:enable: truerequired: truessl:enable: true

请确保将[e-mail]和your-qq-auth-code替换为实际的QQ邮箱地址和授权码。

3. 创建邮件服务

在项目中创建一个名为EmailService.java的类，用于封装邮件发送的逻辑：

package com.example.demo.service;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;import javax.mail.internet.MimeMessage;@Service
public class EmailService {@Autowiredprivate JavaMailSender mailSender;public void sendSimpleEmail(String to, String subject, String content) {MimeMessage mimeMessage = mailSender.createMimeMessage();MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);helper.setFrom("[e-mail]"); // 发件人地址helper.setTo(to); // 收件人地址helper.setSubject(subject); // 邮件主题helper.setText(content); // 邮件内容try {mailSender.send(mimeMessage);System.out.println("Email sent successfully.");} catch (Exception e) {System.err.println("Failed to send email: " + e.getMessage());}}
}

同样地，请将[e-mail]替换为你的QQ邮箱地址。

4. 调用邮件服务

在Controller或其他需要发送邮件的地方调用EmailService的sendSimpleEmail方法：

package com.example.demo.controller;import com.example.demo.service.EmailService;
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 {@Autowiredprivate EmailService emailService;@GetMapping("/send-email")public String sendEmail() {String to = "[e-mail]"; // 收件人邮箱地址String subject = "Test Email from QQ"; // 邮件主题String content = "Hello, this is a test email sent from QQ."; // 邮件内容emailService.sendSimpleEmail(to, subject, content);return "Email sending initiated.";}
}

请将[e-mail]替换为实际的收件人邮箱地址。

5. 运行项目

启动Spring Boot项目，并访问
