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.com
port: 465
username: your-qq-email@qq.com # 你的QQ邮箱地址
password: your-qq-auth-code # 你的QQ邮箱授权码
properties:
mail:
smtp:
auth: true
starttls:
enable: true
required: true
ssl:
enable: true
请确保将your-qq-email@qq.com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 {
@Autowired
private JavaMailSender mailSender;
public void sendSimpleEmail(String to, String subject, String content) {
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
helper.setFrom("your-qq-email@qq.com"); // 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your-qq-email@qq.com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 {
@Autowired
private EmailService emailService;
@GetMapping("/send-email")
public String sendEmail() {
String to = "recipient-email@example.com"; // 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recipient-email@example.com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
