SSM整合实现增删改查操作【保姆式教学】

准备工作
- 环境准备
- 数据库准备
开始干活
前端vue项目

准备工作

环境准备

IDEA
mysql 5.7.31
Tomcat 8.5.64
Maven 3.6.3

这是我的环境，版本别差太大就没问题。

数据库准备


CREATE DATABASE `ssmtest`;

USE `ssmtest`;

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user`(
	`userid` INT(10) NOT NULL AUTO_INCREMENT COMMENT '用户ID',
	`username` VARCHAR(100) NOT NULL COMMENT '用户名',
	`password` VARCHAR(100) NOT NULL COMMENT '用户密码',
	`value` INT(10) NOT NULL DEFAULT 1 COMMENT '状态，1正常',
	 KEY `userid`(`userid`)
	
) ENGINE=INNODB DEFAULT CHARSET=utf8;



INSERT INTO `user`(`userid`,`username`,`password`,`value`)VALUES
(1,'keafmd','666',1),
(2,'keafod','888',1);

开始干活

新建个Maven项目ssmtest，加上Web支持

创建完成的效果：

添加依赖
