Spring+SpringMVC+MyBatis整合（山东数漫江湖）

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
