spring boot 使用spring-boot-starter-mail发送邮件

1.引入依赖

    
        org.springframework.boot
        spring-boot-starter-mail
    

2.配置yml

spring: 
  mail:
    host: smtp.qq.com  //服务地址
    username:  //用户邮箱
    password: 授权码
    default-encoding: utf-8

3.工具类，在业务层或者控制层可以按照自己的思路调用

package com.example.demo.common.util;

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

@Component
public class SendMailUtil {
    @Autowired
    private JavaMailSender javaMailSender;


    public void sendMessage(String email,String text) {
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setTo(email);//目标邮箱
        simpleMailMessage.setSubject("主题");
        simpleMailMessage.setText(text);//正文
        simpleMailMessage.setFrom("[email protected]");//发送的邮箱
        javaMailSender.send(simpleMailMessage);
    }
}
