使用 SpringBoot 配置发送邮件功能
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
