獲取QQ 授權碼

https://mail.qq.com/

接著后就會有對應的密鑰了

SpringBoot構建

依賴

這里的建議是 2.0系列的Springboot版本用低一點的郵件依賴

<!--    電子郵件    -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId><version>2.7.18</version>
</dependency>

Yaml配置

spring:mail:default-encoding: UTF-8host: smtp.qq.comport: 587username: 你的郵件password: 剛剛QQ生成的密鑰properties:mail:smtp:starttls:enable: trueauth: truesocketFactory:class: javax.net.ssl.SSLSocketFactorydebug: true

服務編寫

為了方便直接寫在 控制層 了

package com.takem.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@RestController
public class EmailController {@Autowiredprivate JavaMailSender mailSender;@GetMapping("/email")public String sendSimpleMessage() {SimpleMailMessage mailMessage = new SimpleMailMessage();mailMessage.setFrom("自己的郵箱");mailMessage.setTo("別人的郵箱");mailMessage.setText("這是內容");mailMessage.setSubject("這是郵件標題");mailSender.send(mailMessage);return "====完成發送！====";}
}

測試

以自己發給自己為例
