1、使用 SpringBoot 配置发送邮件功能

项目总体结构

用户表设计

SET FOREIGN_KEY_CHECKS=0;
CREATE DATABASE sample;
USE sample;
set names utf8;
-- ----------------------------
-- Table structure for tab_mail
-- ----------------------------
DROP TABLE IF EXISTS `tab_mail`;
CREATE TABLE `tab_mail` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(100) DEFAULT NULL,
  `password` varchar(100) DEFAULT NULL,
  `email` varchar(100) DEFAULT NULL,
  `active_code` varchar(100) DEFAULT NULL,
  `active_status` int(11) DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2、搭建 SpringBoot 环境

配置 pom.xml 文件
