Spring+SpringMVC+MyBatis（SSM）在我们项目中是经常用到的，这篇文章主要讲解使用Intellij IDEA整合SSM，具体环境如下：
- 数据库：MySQL5.7
- 依赖管理：Maven
- IDE：Intellij IDEA
- JDK：1.8
- 服务器：Tomcat 9
首先用Intellij IDEA创建Maven项目，如果还不知道怎么创建的朋友可以先去百度谷歌，网上很多这种教程，这里我主要讲解SSM整合的过程，项目目录结构如下：
1.创建表，插入数据
CREATE TABLE user (
id INTEGER PRIMARY KEY AUTO_INCREMENT,
name CHAR(20) NOT NULL,
password CHAR(40) NOT NULL
)
ENGINE = InnoDB
AUTO_INCREMENT = 16
DEFAULT CHARSET = utf8;- 1
- 2
- 3
- 4
- 5
- 6
- 7
- 8
INSERT INTO user (id,name, password) VALUES (1,'A', '123');
INSERT INTO user (id,name, password) VALUES (2,'B', '456');- 1
- 2
2.添加Maven依赖
