spring boot 使用邮箱

0、准备

导入邮箱启动器依赖

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

登录qq邮箱

1) 找到设置

2) 找到账户

3) 开启第三方控制发送邮箱

按照如图配置

1、配置application.properties

spring.mail.username=1051513344@qq.com
spring.mail.password=***
spring.mail.host=smtp.qq.com
spring.mail.properties.mail.smtp.ssl.enable=true

其中spring.mail.password为qq邮箱的授权码

qq邮箱生成授权码：

2、测试发送邮箱

简单文本邮箱

package com.laoxu.springboot;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;

@SpringBootTest
class SpringBoot05MailApplicationTests {


    @Autowired
    JavaMailSenderImpl mailSender;


    @Test
    void contextLoads() {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setSubject("通知-今晚开会");
        simpleMailMessage.setText("今晚19:30开会");
        simpleMailMessage.setTo("2448893124@qq.com");
        simpleMailMessage.setFrom("1051513344@qq.com");
        mailSender.send(simpleMailMessage);
    }

}

相关说明：

import javax.mail.internet.MimeMessage;
import java.io.File;

@SpringBootTest
class SpringBoot05MailApplicationTests {

    @Test
    void test02() throws Exception{
        MimeMessage mimeMessage = mailSender.createMimeMessage();

        helper.setTo("2448893124@qq.com");
        helper.setFrom("1051513344@qq.com");

        //上传文件
        helper.addAttachment("1.jpg",new File("C:\\Users\\xushunjie\\Desktop\\1.jpg"));
