记录一次简单的springboot发送邮件功能

场景：经常在我们系统中有通过邮件功能找回密码，或者发送生日祝福等功能，今天记录下springboot发送邮件的简单功能

1.引入maven

<!--        邮件开发-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2.以qq邮箱为例，开启pop3/smtp,并记住授权码

3.在配置文件中配置相关信息（密码为刚刚开启的授权码，不是你邮箱登录密码）

4.创建发送邮箱类

package com.chen.dockerdemo.maildemo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

/**
 * @author chenxiaokang
 * @date 2020/1/14 16:14
 */
@Component
public class EmailService {
    @Autowired
    private JavaMailSender mailSender;

    /**
     * 简单的邮件发送测试
     */
    public void sendMsg(){
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        // 邮件发送者
        mailMessage.setFrom("729***064@qq.com");
        // 邮件接收者
        mailMessage.setTo("cxk***787***39@163.com");
        // 邮件主题
        mailMessage.setSubject("java 测试邮箱发送");
        // 邮件内容
        mailMessage.setText("你已成功收到我发的消息");
        mailSender.send(mailMessage);
    }
}

5.编写测试类

package com.chen.dockerdemo.controller;

import com.chen.dockerdemo.config.MyPro;
import com.chen.dockerdemo.maildemo.EmailService;
import lombok.extern.slf4j.Slf4j;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * @author chenxiaokang
 * @date 2020/1/14 13:54
 */
@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
class HelloWordControllerTest {

    @Autowired
    EmailService emailService;
    @Test
    void maiLSend(){
        emailService.sendMsg();
    }
}
6.邮件发送成功
